Characterization of patient population receiving bioactive glass bone graft substitute as intraoperative treatment for orthopaedic trauma fractures. J Orthop 2024; 55:129-133. [PMID: 38706585 PMCID: PMC11063113 DOI: 10.1016/j.jor.2024.04.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Accepted: 04/14/2024] [Indexed: 05/07/2024] Open
Abstract
Background Bioactive glass synthetic bone grafts are used to treat osseous defects in orthopaedic surgery. Characterization of the clinical scenarios associated with bioactive glass use in the context of orthopaedic trauma, are not well established. This study aims to characterize population demographics, operative variables, as well as postoperative variables, for patients who required bone grafting for treatment of traumatic orthopaedic injuries and received a bioactive glass bone substitute intraoperatively. Methods The electronic medical record at a large Level I trauma center was queried for fracture patients between January 1st, 2019, and April 30th, 2022. Our retrospective cohort included fracture patients who received Fibergraft Matrix or Fibergraft Putty intraoperatively, and their respective control groups. This study ascertained patient demographic variables, operative variables, and postoperative variables. Differences in categorical variables were tested with Fischer's Exact Tests, while differences in continuous variables were tested with ANOVA. Statistical significance was determined as P < 0.05. If the overall Group model was significant for a given variable, post-hoc Fischer's Exact or Tukey HSD tests were used to assess pairwise significance between individual Group pairs. Results A total of four categories across our analysis of demographic, operative, and postoperative variables displayed significant differences amongst subject Groups (P ≤ 0.03). Individual groups were compared such that significant differences between subject groups could be appreciated for a specific variable. FM subjects had greater length of surgery, billable costs, and vitamin D supplementation at the time of surgery compared to FM controls. Similarly, FP subjects had greater length of surgery, billable cost, and implants used intraoperatively compared to FP controls. Conclusion This analysis revealed Fibergraft patients to have greater length of surgery and billable cost, with respect to their matched controls. These data suggest that Fibergraft patients had more severe orthopaedic fractures compared to matched controls.

Eur J Trauma Emerg Surg 2024:10.1007/s00068-024-02596-7. [PMID: 39020128 DOI: 10.1007/s00068-024-02596-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Accepted: 07/02/2024] [Indexed: 07/19/2024]
Abstract
PURPOSE In pertrochanteric femur fractures the risk for fracture healing complications increases with the complexity of the fracture. In addition to dynamization along the lag screw, successful fracture healing may also be facilitated by further dynamization along the shaft axis. The aim of this study was to investigate the mechanical stability of additional axial notch dynamization compared to the standard treatment in an unstable pertrochanteric femur fracture treated with cephalomedullary nailing. METHODS In 14 human cadaver femora, an unstable pertrochanteric fracture was stabilized with a cephalomedullary nail. Additional axial notch dynamization was enabled in half of the samples and compared against the standard treatment (n = 7). Interfragmentary motion, axial construct stiffness and load to failure were investigated in a stepwise increasing cyclic load protocol. RESULTS Mean load to failure (1414 ± 234 N vs. 1428 ± 149 N, p = 0.89) and mean cycles to failure (197,129 ± 45,087 vs. 191,708 ± 30,490, p = 0.81) were equivalent for axial notch dynamization and standard treatment, respectively. Initial construct stiffness was comparable for both groups (axial notch dynamization 684 [593-775] N/mm, standard treatment 618 [497-740] N/mm, p = 0.44). In six out of seven specimens the additional axial dynamization facilitated interfragmentary compression, while maintaining its mechanical stability. After initial settling of the constructs, there were no statistically significant differences between the groups for either subsidence or rotation of the femoral head fragment (p ≤ 0.30). CONCLUSION Axial notch dynamization provided equivalent mechanical stability compared to standard treatment in an unstable pertrochanteric fracture. Whether the interfragmentary compression generated by axial notch dynamization will promote fracture healing through improved fracture reduction needs to be evaluated clinically.

Abstract
The study aimed to validate a newly developed postoperative stability score for evaluating clinical follow-up in elderly patients with low-energy hip fractures. From 1 January 2020 to 31 December 2021, we enrolled patients aged over 65 who underwent cephalomedullary nail fixation using proximal femoral nail antirotation II (PFNAII) and had at least 6 months of follow-up; excluding multiple fractures, pathological fractures, and periprosthetic fractures. We collected general patient data. Parameters such as TAD, Parker's ratio (AP and lateral), and the new postoperative stability score were recorded. A loss of reduction was defined using the decline in the Chang reduction quality criteria (CRQC) score within one month. Among the 108 enrolled patients, 23 (21.3%) experienced a loss of reduction, with a mean age of 82.1 years and a mean follow-up time of 7.4 months. Univariate analysis showed no significant association between loss of reduction and general data. However, the new postoperative stability score correlated significantly with loss of reduction (mean scores: 6.68 vs. 4.83, p = 0.045). Multivariate analysis confirmed this association (odds ratio: 0.076, 95% confidence interval: 0.022-0.263, p < 0.05). The newly developed postoperative stability score, incorporating surgical technique assessment, improves prediction accuracy for loss of reduction in elderly intertrochanteric fracture (ITF) patients.

Abstract
In this retrospective cohort study of adult stem cell transplanted patients (n = 8463), a significant increased risk of both MOF and hip fractures was seen compared with the Swedish population and occurred in mean more than 2 years after stem cell transplantation. PURPOSE To explore the risk for osteoporotic fracture in patients who have undergone hematopoietic stem cell transplantation (HSCT) compared with the Swedish population. METHODS The risk of osteoporotic fractures was determined in a retrospective population cohort study of adult (≥ 18 years) Swedish patients (n = 8463), who were transplanted with HSCT 1997-2016 and compared with all adults living in Sweden during the same period. RESULTS In the total study group (n = 8463), 90 hip fractures (1.1% both in males and females) and 361 major osteoporotic fractures (MOF) (3.2% in men and 6.0% in women) were identified. In the total study population, the ratio of observed and expected number of hip fracture for women was 1.99 (95% CI 1.39-2.75) and for men 2.54 (95% CI 1.91-3.31). The corresponding ratio for MOF in women was 1.36 (CI 1.18-1.56) and for men 1.61 (CI 1.37-1.88). From 2005 onwards, when differentiation in the registry between allo- and auto-HSCT was possible, the observed number of hip fracture and MOF in allo-HSCT (n = 1865) were significantly increased (observed/expected hip fracture 5.24 (95% CI 3.28-7.93) and observed/expected MOF 2.08 (95% CI 1.63-2.62)). Fractures occurred in mean 2.7 (hip) and 2.5 (MOF) years after allo-HSCT. Graft-versus-host disease (GVHD) was not associated with an increased risk of fracture. CONCLUSION Patients who underwent HSCT had an increased risk of both hip and major osteoporotic fracture compared with the Swedish population and occurred in 4.3% of patients. GVHD was not statistically significantly associated with fracture risk.

Abstract
Osteoporotic fractures, also known as fragility fractures, are reflective of compromised bone strength and are associated with significant morbidity and mortality. Such fractures may be clinically silent, and others may present clinically with pain and deformity at the time of the injury. Unfortunately, and even at the time of detection, most individuals sustaining fragility fractures are not identified as having underlying metabolic bone disease and are not evaluated or treated to reduce the incidence of future fractures. A multidisciplinary international working group with representation from international societies dedicated to advancing the care of patients with metabolic bone disease has developed best practice recommendations for the diagnosis and evaluation of individuals with fragility fractures. A comprehensive narrative review was conducted to identify key articles on fragility fractures and their impact on the incidence of further fractures, morbidity, and mortality. This document represents consensus among the supporting societies and harmonizes best practice recommendations consistent with advances in research. A fragility fracture in an adult is an important predictor of future fractures and requires further evaluation and treatment of the underlying osteoporosis. It is important to recognize that most fragility fractures occur in patients with bone mineral density T scores higher than -2.5, and these fractures confirm the presence of skeletal fragility even in the presence of a well-maintained bone mineral density. Fragility fractures require further evaluation with exclusion of contributing factors for osteoporosis and assessment of clinical risk factors for fracture followed by appropriate pharmacological intervention designed to reduce the risk of future fracture. Because most low-trauma vertebral fractures do not present with pain, dedicated vertebral imaging and review of past imaging is useful in identifying fractures in patients at high risk for vertebral fractures. Given the importance of fractures in confirming skeletal fragility and predicting future events, it is recommended that an established classification system be used for fracture identification and reporting.

Osteoporos Int 2024:10.1007/s00198-024-07156-8. [PMID: 38922398 DOI: 10.1007/s00198-024-07156-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Accepted: 06/16/2024] [Indexed: 06/27/2024]
Abstract
Oslo in Norway has had the highest incidence of hip fractures in the world. The incidence in Oslo has been thoroughly described every decade since the late 1970s. The incidence in Oslo has previously been higher compared to the rest of Norway but has now decreased to a level below the country average. PURPOSE The purpose of this study was to report the incidence of hip fractures in Oslo in 2019 and compare it with the incidence rates from the previous four decades. METHODS Patients residing in Oslo in 2019 with a new hip fracture identified by searching the Oslo hospital's patient administrative systems and protocols from the operating theaters. The diagnosis was verified through medical records and/or radiographs. To compare with previous studies, the direct standardization method was used with the population of Oslo in 2019 as the standard. RESULTS A total of 758 hip fractures, 70% women, were identified in 2019. The age-standardized incidence rates per 10,000 person-years in 2019 (95% CI) were 45 (41.1-48.8) for women and 30 (25.8-33.8) for men. In women, there has been a continuous decline in age-standardized rates the last three decades and in men the last two decades. The most pronounced decline was seen in the oldest age groups over 70 years. There has been a secular decline in both cervical and trochanteric fractures; however, the decrease in trochanteric fractures was most distinct for males, with more than two times higher risk in 1996/1997 compared to 2019. CONCLUSION Incidence rates for hip fractures in Oslo in 2019 were the lowest rate reported since 1978. The decrease was significant for both men and women. For the first time, the incidence rates are below the national rates of Norway. However, the rates are still among the highest worldwide.

Abstract
Purpose Hip fractures are associated with increased mortality. The identification of risk factors of mortality could improve patient care. The aim of the study was to identify risk factors of mortality after surgery for a hip fracture and construct a mortality model. Materials and Methods A cohort study was conducted on patients with hip fractures at two institutions. Five hundred and ninety-seven patients with hip fractures that were treated in the tertiary hospital, and another 147 patients that were treated in a secondary hospital. The perioperative data were collected from medical charts and interviews. Functional Assessment Measure score, Short Form-12 and mortality were recorded at 12 months. Patients and surgery variables that were associated with increased mortality were used to develop a mortality model. Results Mortality for the whole cohort was 19.4% at one year. From the variables tested only age >80 years, American Society of Anesthesiologists category, time to surgery (>48 hours), Charlson comorbidity index, sex, use of anti-coagulants, and body mass index <25 kg/m2 were associated with increased mortality and used to construct the mortality model. The area under the curve for the prediction model was 0.814. Functional outcome at one year was similar to preoperative status, even though their level of physical function dropped after the hip surgery and slowly recovered. Conclusion The mortality prediction model that was developed in this study calculates the risk of death at one year for patients with hip fractures, is simple, and could detect high risk patients that need special management.

Abstract
INTRODUCTION Despite the recent increase in the use of cephalomedullary nails for trochanteric hip fractures, factors that may be associated with peri‑implant femoral fracture (PIFF) after cephalomedullary nailing for trochanteric fractures remain unknown. We investigated the factors associated with PIFF after cephalomedullary nailing of trochanteric hip fractures in older patients. METHODS A nested case-control study was conducted using a database of patients aged ≥65 years who underwent surgery with cephalomedullary nails for trochanteric fractures caused by low-energy trauma during 2005-2021. The cases were defined as patients who developed PIFF after surgery, while controls were patients who did not develop PIFF and who were followed up for ≥3 years after surgery. Four controls were randomly matched to each case for sex and age. First, potential factors associated with PIFF were compared between cases and controls. Second, multivariable conditional logistic regression analysis was employed to assess factors possibly associated with PIFF, controlling for potential confounding factors. RESULTS Of 1531 patients who underwent surgery with cephalomedullary nails because of trochanteric fractures, we assessed 34 cases and 136 controls (N = 170; mean age 85.7 ± 7 years; and females, 94 %). PIFF was significantly associated with patients having undergone total knee arthroplasty (adjusted odds ratios [95 % confidence intervals], 4.41 [1.16-16.8]) and those with AO/OTA classification 31A3 fracture (A3 fracture) (2.3 [1.12-4.76]), after adjusting for potential confounding factors. CONCLUSIONS Our results showed that PIFF was more likely to develop among older patients with a clinical history of total knee arthroplasty and A3 fracture. These findings suggest that such patients may require careful follow-up with rigorous assessments after cephalomedullary nailing for trochanteric fractures.

Abstract
INTRODUCTION Hip fractures are life-changing injuries with associated one-year mortality up to 30%. Five locations in the world have been termed "blue zones," where the longevity of the population is markedly higher than that of surrounding areas and there are 10 times more centenarians. The United States has one blue zone (Loma Linda, California), which is believed to be because of the lifestyle of the Seventh-day Adventist population living there. We hypothesized that patients from the blue zone experience low-energy, frailty-driven, osteoporotic hip fractures later in life and an increased postinjury longevity relative to non-blue zone control subjects. METHODS A review of patients treated for hip fracture between January 2010 and August 2020 from a single institution was conducted. Demographic data were collected, and the end point of mortality was assessed using death registry information, queried in April 2024. Groups were divided into blue zone and non-blue zone. Statistical analysis was conducted with P < 0.05 considered significant. RESULTS Complete data were available for 1,032 patients. The blue zone cohort sustained low-energy hip fractures 12 years later in life (83.2 versus 71.1, P < 0.01). Propensity score matching was used to account for this difference. After propensity score matching, age, body mass index, American Society of Anesthesiologists score, surgery performed, sex, mechanism, ethnicity, diabetes, chronic obstructive pulmonary disease, CHF, chronic kidney disease grade, dementia, surgical time, and drug/tobacco/marijuana use were similar between groups. Blue zone patients had lower mortality at both 1 and 2 years postoperatively (12% versus 24%, P = 0.03 and 20% versus 33%, P = 0.03, respectively), had more hypertension (76% versus 62%, P = 0.03), reported lower alcohol use (7% versus 20%, P < 0.01), and included more Seventh-day Adventists (64% versus 15%, P < 0.01). CONCLUSION The blue zone lifestyle affected the onset of frailty and delayed osteoporotic hip fracture by 12 years in this propensity-matched cohort study. Postoperative mortality was also markedly lower in the blue zone cohort.

Abstract
Prozessänderungen im perioperativen Setting werden selten analysiert, weil ihre Ergebnisse nicht unmittelbar fassbar sind und es einer hohen Fallzahl bedarf. Primäres Ziel war es, Prozessänderungen retrospektiv anhand proximaler Femurfrakturen (PF) zu evaluieren und deren Effekt mit verschiedenen Zielkriterien zu überprüfen. Sekundäres Ziel war die Definition möglicher Qualitätskriterien für die Versorgung von PF.Retrospektive Analyse der Datenbank eines Level-1-Traumazentrums zu PF. Eingeschlossen wurden alle osteosynthetisch und endoprothetisch versorgten PF im Behandlungszeitraum vom 01.01.2006 bis 31.12.2021. Der Zeitraum von 16 Jahren wurde für die Statistik trichotom aufgeteilt und die ersten 6 Jahre als Ausgangsbasis verwendet. Insgesamt 10 Prozessänderungen wurden in den folgenden 10 Jahren vorgenommen. Die Auswirkungen dieser Änderungen wurden anhand 1. der operativen Revisionsrate, 2. der Infektionsrate, 3. der perioperativen Transfusionsrate sowie 4. der 1-Jahres-Letalität überprüft.Insgesamt 4163 PF wurden analysiert. Hinsichtlich der Zielkriterien zeigten die Änderungen der ersten 5 Jahre (2012-2016; intramedulläres Verfahren für Osteosynthesen sowie Einwegabdeckung und Einwegkittel) den stärksten Effekt mit einer erstmaligen Senkung der operativen Revisionsrate unter 10% auf Dauer. Weitere Prozessoptimierungen der letzten 5 Jahre (2017-2021) erbrachten ebenfalls messbare Verbesserungen (Senkung der Infektions- und Transfusionsrate). Die 1-Jahres-Letalität blieb unverändert, auch während der COVID-19-Pandemie.Prozessänderungen bei PF führen nicht unmittelbar zu objektiv messbaren Verbesserungen. Rückblickend erscheint der Paradigmenwechsel von extra- auf intramedulläre Osteosynthese den höchsten Effekt erzielt zu haben, wenngleich über die letzten 10 Jahre eine schrittweise Besserung aller Zielkriterien eintrat - mit Ausnahme der Letalität. Als objektive Qualitätskontrolle sollte eine 1-Jahres-Revisionsrate unter 10% angestrebt sein.

Abstract
PURPOSE Although trochanteric fractures (TF) are a frequent event in the geriatric population, studies reporting on complication rates associated with surgical treatment are sparse. Thus, this study investigated the relevance of fracture-, implant-, and surgery-associated complications in TF. Furthermore, the role of possible risk factors for the before mentioned complications was investigated. METHODS A consecutive series of patients with TF treated by intramedullary nailing with a sliding screw device was evaluated. Data were sampled retrospectively from the hospital patient information system and anonymized at the source. Demographic data and information regarding fracture pattern, the treatment performed, hospital stay, and evaluation of operative and follow-up radiographs were analyzed. Intraoperative problems (i.e., technical problems with the implant, intraoperative fracture) and postoperative complications were investigated. RESULTS Postoperative surgical complications were noted in 11.7%. The most frequent surgical problem was a difficult fracture reduction (13%) and intraoperative fracture dislocation (3.6%). The most frequent postoperative complication was intra-hospital mortality (3.6%), delayed/non-union (2.7%), and a cut-out of the lag screw in the femoral head (2.3%). Implant failure (1,4%) was significantly associated with morbid obesity while cut-out (2,3%) correlated with a higher tip-apex distance (TAD). A complex fracture type and a suboptimal screw position significantly increased the cut-out rate to 5% (p = 0.018). CONCLUSION Complications after TF treatment occur frequently. While patient-associated variables such as morbid obesity cannot be influenced by the surgeon, correct fracture reduction and implant positioning remain to be of highest importance.

Abstract
OBJECTIVE This study aimed to critically assess existing risk prediction models for postoperative mortality in older individuals with hip fractures, with the objective of offering substantive insights for their clinical application. DESIGN A comprehensive search was conducted across prominent databases, including PubMed, Embase, Cochrane Library, SinoMed, CNKI, VIP, and Wanfang, spanning original articles in both Chinese and English up until 1 December 2023. Two researchers independently extracted pertinent research characteristics, such as predictors, model performance metrics, and modeling methodologies. Additionally, the bias risk and applicability of the incorporated risk prediction models were systematically evaluated using the Prediction Model Risk of Bias Assessment Tool (PROBAST). RESULTS Within the purview of this investigation, a total of 21 studies were identified, constituting 21 original risk prediction models. The discriminatory capacity of the included risk prediction models, as denoted by the minimum and maximum areas under the subject operating characteristic curve, ranged from 0.710 to 0.964. Noteworthy predictors, recurrent across various models, included age, sex, comorbidities, and nutritional status. However, among the models assessed through the PROBAST framework, only one was deemed to exhibit a low risk of bias. Beyond this assessment, the principal limitations observed in risk prediction models pertain to deficiencies in data analysis, encompassing insufficient sample size and suboptimal handling of missing data. CONCLUSION Subsequent research endeavors should adopt more stringent experimental designs and employ advanced statistical methodologies in the construction of risk prediction models. Moreover, large-scale external validation studies are warranted to rigorously assess the generalizability and clinical utility of existing models, thereby enhancing their relevance as valuable clinical references.

Abstract
Most trochanteric fractures are treated by fixation, most often intramedullary. Nevertheless, the desire to have patients walk as soon as possible and the fear of fixation failure has driven some surgeons to carry out an arthroplasty instead, especially for unstable fractures and/or in patients with severe osteoporosis, in order to avoid the difficult conversion to arthroplasty later on if the fixation fails. The aim of this review was to specify the role, technique and results of performing arthroplasty in this context. In which fractures? Unstable fractures (A2.2, A2.3 and A3), especially in osteoporotic bone, which are the most difficult to reduce and fix, and in cases with associated osteoarthritis. For which patients? Arthroplasty should not be done in patients who have ASA≤3 due to greater blood loss and longer operative time. Since the postoperative Parker score often drops, arthroplasty should not be done in patients having a Parker score<6. What are the technical problems? Arthroplasty must be done by an experienced surgeon because of the lack of anatomical landmarks, although fracture fixation has its own demands (satisfactory reduction, appropriate length and position of cervicocephalic screw). What are the results and complications? Despite several comparative studies (randomized trials, meta-analysis and prospective studies), it is difficult to draw any conclusions. These studies show worse performance of dynamic hip screws relative to intramedullary nails. The complication and revision rates were higher for nails than arthroplasty, but not in every study, while the functional outcomes with nails (with or without immediate weightbearing) were better than those of arthroplasty beyond 6 months. What is the mortality rate? It was lower after nailing in a few studies but was mainly determined by the patient's comorbidities and preoperative Parker score. The best indication for arthroplasty may be self-sufficient patients over 70 years of age who have an unstable fracture with severe osteoporosis. Nevertheless, new studies should be done to compare arthroplasty to nailing with immediate return to weightbearing in patients having the same type of fracture, defined using 3D CT scan. Level of evidence: Expert advice.

Abstract
Delirium is associated with greater morbidity, higher mortality, and longer periods of hospital day after hip fracture. There are number of studies on postoperative delirium after a hip fracture. However, few studies have made a distinction between preoperative and postoperative delirium. The purpose of this study is to compare risk factors and clinical outcome between preoperative and postoperative delirium in elderly patients with a hip fracture surgery. A total of 382 consecutive patients aged > 65 years who underwent operation for hip fracture were enrolled. Among them, the patients diagnosed with delirium were divided into 2 groups (a preoperative delirium group and a postoperative delirium group) according to the onset time of delirium. To evaluate risk factors for preoperative and postoperative delirium, we analyzed demographic data, preoperative laboratory data, and perioperative data. To compare clinical outcomes between preoperative and postoperative delirium, we analyzed postoperative complications, KOVAL score, regression, readmission, and 2-year survival rate. Delirium was diagnosed in 150 (39.3%) patients during hospitalization. Preoperative and postoperative delirium occurred in 67 (44.6%) and 83 (55.4%) patients, respectively. Independent risk factors of preoperative delirium included age (odds ratio: 1.47, 95% confidential interval [CI]: 1.13-2.23, P = .004), stroke (odds ratio [OR]: 2.70, 95% CI: 1.11-6.01, P = .015), American Society of Anesthesiologist (OR: 1.68, 95% CI: 1.137-2.24, P = .033), and time from admission to operation (OR: 1.08, 95% CI: 1.01-1.16, P = .031). There was no significant difference in preoperative KOVAL score between the 2 groups. However, postoperative KOVAL score (5.1 ± 2.0 vs 4.4 ± 2.1, P = .027) and regression rate (68.7% vs 44.6%, P = .029) were significantly higher in the preoperative delirium group than in the postoperative delirium group. Moreover, the 2-year survival rate was significantly lower in the preoperative delirium group than in the postoperative delirium group (62.7% vs 78.3%, P = .046). Characteristics, risk factors, and prognosis are different for patients with preoperative delirium and postoperative delirium. Preoperative delirium patients showed different risk factors with poorer prognosis and higher mortality. Therefore, hip fracture patients with risk factors for preoperative delirium should be monitored more carefully due to their greater risk of mortality.

Abstract
INTRODUCTION AND IMPORTANCE Knee arthroplasties as an effective intervention is primarily performed in patients with primary osteoarthritis and rheumatoid arthritis. Risk of hip fracture may be either decreased or increased in patients with Knee arthroplasties. There is conflicting evidence in this regard. Over the years, some studies have reported the occurrence of hip fractures following this operation as a rare but severe complication. The aim of the present case series was to report diagnosis and treatment of the mentioned five cases. CASE PRESENTATION During a period of two years, five patients with a diagnosis of a subtrochanteric fracture and history of total knee arthroplasty who referred to hospital were selected to include in the present case series. CLINICAL DISCUSSION: the presence of RA and treatment with glucocorticoids, a reduction of BMD following knee replacement surgery, and ultimately, an increase in physical activity and movement after the arthroplasty due to the improvement of preoperational pain, may all contribute in a complex manner to the observed outcome of increased fracture risk in the hip following TKA. CONCLUSION In summary, special care including using medications to improve BMD should be taken to minimize the risk of such an event.

Abstract
OBJECTIVE Intertrochanteric fracture is one type of hip fracture, which is the most serious consequence of osteoporosis. Along with the growing elderly population, intertrochanteric fracture is expected to rise increasingly. The aim of this study was to assess excess mortality after intertrochanteric fractures and to identify the predictors of long-term mortality by therapy among patients aged 50 years and older in Tianjin. METHODS This is a retrospective cohort study on mortality for 3029 patients aged 50 years and older in Tianjin experiencing an intertrochanteric fracture between December 26, 2014 and December 31, 2018. Data were from Tianjin Hospital Hip Fracture (THHF) cohort. Follow-up period was until March 31, 2022. Mortality, excess mortality, and comorbidities were analyzed and stratified by therapy and gender. Time dependent Cox models were performed to estimate the effects of the variables. RESULTS Absolute mortality for all the patients was 5.90% at 3 months, 12.55% at 12 months, 19.92% at 24 months and 27.28% at 36 months. Absolute mortality for surgical group was 1.57% at 3 months, 4.77% at 12 months, 8.49% at 24 months and 12.07% at 36 months, significantly lower than conservative group: 10.50% at 3 months, 20.73% at 12 months, 31.96% at 24 months and 43.04% at 36 months. We found a substantially lower mortality (hazard ratio [HR] 0.34, 95% confidence internal, [CI]: 0.23-0.52, p = 0.000) among patients undergoing surgical therapy than those undergoing conservative therapy, even when controlled for gender, age, the length of hospital stay, and all the comorbidities. Female patients (HR 0.68, 95% CI: 0.58-0.79, p = 0.000) were less likely to die than male patients after an intertrochanteric fracture. Patients treated by the two methods were both found to have excess mortality rates compared to the general population, although in different levels. The excess mortality rates for patients in the conservative therapy group were 14.46% in males and 17.93% in females, while in the surgical therapy group, 2.78% in females and 4.37% in males. The comorbidities moderate or severe renal disease (HR 2.19, 95% CI: 1.61-2.98, p = 0.000), metastatic solid tumor (HR 6.35, 95% CI: 1.56-25.85, p = 0.010), hypoproteinemia (HR 1.22, 95% CI: 1.01-1.47, p = 0.034), and older age (HR 1.89, 95% CI: 1.73-2.08, p = 0.000) were also risk factors on mortality. A worse-case analysis for the primary outcome were performed as sensitivity analysis and it was consistent with the original conclusion. CONCLUSION Intertrochanteric factures for people aged 50 years older were found to have excess mortality compared to the general population in Tianjin city, and preventing the fractures in the hip for elderly people was imperative. After controlling tfor comorbidities and age, female gender and surgical therapy were protective factors for the death after fractures, which could provide strong evidence for patients and surgeons to make decisions.

Abstract
OBJECTIVE Intertrochanteric fracture is a very common but serious type of hip fracture in nonagenarians. The surgical treatment remains a significant challenge for orthopedists. The objective of this study was to investigate postoperative complications and survival outcomes compared between bipolar hemiarthroplasty (HA) and proximal femoral nail anti-rotation (PFNA) in nonagenarians with intertrochanteric fractures, and to evaluate the efficacy and safety of the two surgical procedures in this patient population. METHODS A total of 113 consecutive nonagenarians who underwent bipolar HA or PFNA for the treatment of intertrochanteric fractures from January 2006 to August 2021 were retrospectively studied in the current paper. There were 34 males and 79 females, with a mean age of 92.2 years (range 90-101 years) at the time of operation. The average duration of follow-up was 29.7 months (range 1-120 months). The full cohort was divided into bipolar HA (77 cases) and PFNA (36 cases) groups. Damage control orthopedics was used to determine the optimal surgery time and assist in perioperative management. A restrictive blood transfusion strategy was employed, along with appropriate adjustments under multidisciplinary assessment, throughout the perioperative period. Perioperative clinical information and prognostic data were analyzed. Kaplan-Meier survival curves were used for survival analysis, and landmark analysis divided the entire follow-up period into 1-12 months (short-term), 13-42 months (medium-term) and 43-120 months (long-term) according to the configurations of Kaplan-Meier survival curves. RESULTS Both groups had similar general variables except for the proportion of high adjusted Charlson comorbidity index (aCCI) (≥6 points) (6.5% in bipolar HA group and 22.2% in PFNA group, p = 0.024). Intraoperative blood loss and transfusion requirements were greater, and the intraoperative transfusion rates were higher in the bipolar HA group compared to the PFNA group (all p < 0.05). The complications rates, 1- to 60-month cumulative all-cause mortality, postoperative optimal Harris hip score (HHS), and Barthel index (BI) presented no significant difference between the two groups (all p > 0.05). Both groups had similar overall survival curves (p = 0.37). However, landmark analysis revealed that bipolar HA group exhibited higher survival rates in medium-term (p = 0.01), while similar survival rates were observed in the short- and long-term post-operation periods (both p > 0.05). Cox regression with survival-time-dependent covariate calculated the hazard ratio (HR) of bipolar HA was 0.41 in medium-term (p = 0.039). CONCLUSION Bipolar HA is equally effective and reliable as PFNA for treating intertrochanteric fractures in nonagenarians. Despite resulting in more intraoperative blood loss and transfusions, bipolar HA therapy is associated with a higher medium-term survival rate compared to PFNA treatment. The application of damage control orthopedics and precise perioperative patient blood management could contribute to the positive clinical outcomes observed in this patient population.

Introduction We introduced a novel numerical index known as posterior protrusion measures (PPM), derived from lateral plain radiograph images, which effectively serves to distinguish stable from unstable pertrochanteric fractures. The present study aims to scrutinize PPM values among two classified fracture patterns, stable and unstable, within the three-dimensional (3D) CT classification system, establishing a numeric threshold for PPM to differentiate between these groups; explore the potential relationship between the PPM index and unclassified categories; investigate how groups divided by the PPM threshold value can predict fracture stability based on 3D CT. Materials and methods In this study, three observers were tasked with measuring PPM on a single occasion. The chi-square test assessed the association between each demographic parameter on a categorical scale and stable/unstable groups. Continuous variables were also subject to examination. Receiver operating characteristic (ROC) analysis was employed to determine optimal cut-off points of PPM for predicting the presence of stable versus unstable groups. Additionally, the chi-square test examined the linear relation between separated groups based on the defined threshold PPM value and the stable/unstable groups. Results A total of 106 pertrochanteric fractures were identified using CT scan images and plain radiographs in the 3D CT classification system, revealing the stable group of 35 patients and the unstable group of 71 patients. The PPM values for stable/unstable fractures were, on average (± standard deviation), 0.34±0.25/0.50±0.29 for observer 1, 0.31±0.23/0.57±0.31 for observer 2, and 0.41±0.29/0.57±0.26 for observer 3, respectively (p<0.01). We established 0.3 as the cut-off value for PPM. The average PPM value among three observers represented each patient to assess fracture stability. The group with PPM <0.3 included 27 patients (16 stable and 11 unstable), and the group with PPM ≥0.3 group comprised 79 patients (19 stable and 60 unstable; p<0.005). Conclusion The present study revealed a significant difference in PPM values among stable and unstable 3D CT classification groups. Additionally, a threshold PPM value of 0.3 suggests a pivotal point for differentiating fracture stability. This innovative methodology makes a substantial contribution to clinical endeavors, potentially circumventing the necessity for 3D CT scanning.

Abstract
Milk and milk products have been known as important for bone health. Can ingestion of milk and milk products lower hip fracture risk for older adults? In this study, older Icelandic adults who were ingesting higher milk had a lower risk of hip fractures. INTRODUCTION This study describes associations between milk intake and hip fracture risk in older Icelanders. The data indicate that no/low milk consumption is related to greater hip fracture risk. Hip fracture can have a severe effect on the life of older adults. Health authorities recommend milk intake for better bone health. However, previous studies addressing this association have been divergent. METHODS This prospective study included 4614 subjects (mean age 76 years) recruited between 2002 and 2006 into the Age, Gene/Environment Susceptibility-Reykjavik (AGES-Reykjavik) study. Information on hip fractures occurring between recruitment and end of follow-up in 2012 was extracted from hospital records. RESULTS A total of 14% of participants reported milk intake < 0.5 times/day (the lowest category) and 22% of the participants consumed at least milk two times/day (highest category). Milk consumption was positively related to the volumetric bone mineral density at baseline with a sex- and age-adjusted difference of 8.95 ± 2.5 mg/cm3 between the highest compared to lowest milk intake categories (P < 0.001). During the follow-up, 7.4% of participants had a hip fracture, and we observed a decreased risk of incident hip fractures in the highest compared to the lowest milk intake category with a hazard ratio of 0.69 (95% CI: 0.47-0.99) in adjusted model. Further analysis indicated a linear relationship between milk intake and fracture risk (P-value for linear trend < 0.001). CONCLUSION Milk intake is associated with a lower risk of incident hip fracture in a linear way in Icelandic community-dwelling older adults.

Abstract
INTRODUCTION Dynamization of proximal femoral nailing by removal of distal interlocking is one of the recommended treatment options for nonunions of femur fractures. However, in certain inter-/subtrochanteric fractures, gliding of the nail along the femoral shaft is blocked by lateral femoral cortical support of the lag screw. For these cases, Biber et al. proposed lateral cortical notching (LCN), in which the supporting lateral bone is removed. This study investigates the biomechanical effect of LCN on gliding of proximal femoral nailing and stress distribution at the bone/implant interface. MATERIALS AND METHODS In this finite element analysis a three-dimensional model of an unstable intertrochanteric fracture with proximal femoral nailing without distal interlocking was simulated using the FebioStudio software suite. To simulate LCN, the lag screw hole was lengthened to 15.34 mm at the lateral cortex. Displacement of the nail along the femoral shaft axis and von Mises stress distribution were compared between LCN model and standard implantation model. RESULTS Displacement of the nail along the femoral shaft axis was higher in the LCN model than in the standard implantation model (0.48 mm vs. 0.07 mm). Highest von Mises stresses of 176-178 MPa at the implant and of 52-81 MPa at the proximal femur were detected. Maximum von Mises stresses of the implant were comparable at all sides, except for a reduced von Mises stress at the lateral inferior side in the LCN model (80 vs. 102 MPa). At the inferior lateral screw hole and the anterior/posterior lateral screw hole maximum von Mises stress was reduced in the LCN model (2 vs. 49 MPa and 52 vs. 81 MPa), whereas the maximum von Mises stress at the inferior medial screw hole was higher in the LCN model than in the standard implantation model (53 vs. 27 MPa). CONCLUSIONS Lateral cortical notching facilitates gliding of a distally dynamized proximal femoral nail along the femoral shaft axis in intertrochanteric fractures. Additionally, the lack of lateral cortical bone support at the lag screw reduces von Mises stress at the bone/implant interface and thus could lower the risk for implant breakage and peri‑implant fractures.

[PMID: 37474020 DOI: 10.1016/j.otsr.2023.103661] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2022] [Revised: 03/04/2023] [Accepted: 06/06/2023] [Indexed: 07/22/2023]
Abstract
BACKGROUND Trochanteric fractures are a public health issue due to the aging of the population. Treatment aims to reduce their related morbidity and mortality and to allow an early return to independence. Postoperative anemia is associated with poorer functional recovery and an increased mortality rate. The aim of this study was to assess whether minimally invasive side plate fixation (Minimal Invasive Screw System, MISS™) resulted in reduced perioperative bleeding compared with conventional fixation (Pertrochanteric Hip Screw, PHS™). HYPOTHESIS We hypothesized that minimally invasive side plate fixation (MISS) would result in reduced perioperative bleeding compared with conventional fixation (PHS). PATIENTS AND METHODS We conducted an open randomized controlled trial with blinded assessment of the primary outcome. Inclusion criteria were patients aged over 65 years with isolated reducible trochanteric fracture. The 2 surgical implants were of the same shape, the only difference between them being the locking mode of the femoral neck screw on the plate of the MISS device, allowing a percutaneous approach. Primary outcome was perioperative bleeding evaluated with Mercuriali's formula. Secondary outcomes included operating time, scar length, length of hospital stay, radiological criteria such as quality of fracture reduction, implant positioning, bone healing, complications and functional recovery compared between the 2 groups. RESULTS One hundred and eight patients met the inclusion criteria and were randomized to receive either PHS (n=54) or MISS (n=54). Osteosynthesis with MISS significatively reduced perioperative bleeding (median 243mL, interquartile range [152-410] vs. 334mL [247-430] [p=0.0299]), operating time (65min [57-73] vs. 79min [66-89] [p=0.0002]) and scar length after 45 days (7cm [5-8] vs. 14cm [12-15] [p<0.0001]). There was no statistically significant difference between groups in postoperative complications, revision surgery or serious adverse events. CONCLUSION Compared with PHS, MISS reduced operating time, perioperative bleeding and scar length with no observed functional difference. LEVEL OF EVIDENCE I.

Abstract
BACKGROUND Incidence of hip fracture is estimated to rise, increasing demands on healthcare. Our objective was to compare patients with hip fracture, a decade apart, regarding surgical characteristics and functional outcome in relation to morbidity. A secondary aim was to analyse postoperative hand-grip strength (HGS) in relation to walking ability 4 months postoperatively. METHODS This is a cross-sectional comparative study of patients with hip fracture, included in 2008 (n = 78) and 2018 (n = 76) at Örebro University Hospital. Patient-data (age, gender, morbidity, fall-circumstances, fracture, surgical characteristics, and length of stay) were collected from medical records. HGS was measured postoperatively. Data on functional outcome in terms of housing, walking ability and need of walking aids at 4 months postoperatively was collected from the Swedish Hip Fracture Register RIKSHÖFT. Statistical analyses adapted were hypothesis tests and regression analysis. RESULTS Patients in 2018 presented a significantly higher morbidity than patients in 2008 and there were significant differences in adapted surgical methods. Functional outcome at 4-months postoperatively was analysed by logistic regression where Cohort 2018 was associated with higher odds of independent walking ability (OR 5.7; 95%CI 1.9-17.2) and not needing any walking aids (OR 5.1; 95%CI 1.9-17.2). Postoperative HGS was higher among patients in 2018 and a multiple regression analysis revealed a significant association between HGS and walking ability at 4 months postoperatively. CONCLUSIONS This study supports the since previously reported development in hip fracture surgery in Sweden while also presenting that functional outcome seems to have improved despite a concomitant increase in morbidity. Results suggest an improvement in postoperative HGS, predicting walking ability at 4 months postoperatively.

Abstract
BACKGROUND There is limited data on the impact of COVID-19 epidemic on the number of orthopaedic surgeries in Japan. METHODS We conducted a nationwide hospital survey asking for the monthly number of orthopaedic surgeries performed at each facility from January 2019 to June 2021. Those facilities that had performed at least 100 surgeries in 2019 were included for analyses. The facilities were further grouped by prefecture and by hospital characteristics. A brief health economic evaluation was also performed. Risk ratios were compared using univariate analyses with P < 0.05 considered statistically significant. RESULTS Questionnaire was sent to 1988 hospitals with 1671 hospitals (84%) responding. The survey data indicated a total number of orthopaedic surgeries decreased in 2020 compared to 2019 (1,061,541 vs 1,119,955 P < 0.01), and also for the first six months of 2021 compared to the same period in 2019 (530,388 vs 550,378 P < 0.01). In 2020, over 50% of all facilities in nearly all of the prefectures saw a decline in surgical procedures. The risk of incurring more than a 25% decease in the number of surgeries was significantly higher in 2020 for class I designated medical institutions compared to those that were not designated for any types of infectious diseases among the institutions with a tertiary emergency medical center in 2020 (crude risk ratio 2.9: 95% CI 1.2-7.4, p = 0.02) and in 2021 (crude risk ratio 4.7: 95% CI 1 0.9-12.1, p < 0.01). The estimated total nationwide decrease of revenue were in the range of approximately ¥29.2 to ¥116.8 billion per year for orthopaedic surgeries alone. CONCLUSION There was a statistically significant decrease in the number of orthopaedic surgeries in Japan. The magnitude of the decline varied by prefectures and hospital characteristics, with the greater impact imposed on medical institutions with higher classification functions. The estimated immediate health economic impact was sizable.

Abstract
BACKGROUND Proximal femur fractures, including both intracapsular (femoral neck fractures) and extracapsular fractures (intertrochanteric femoral fractures, IFFs), affect around 1.5 million people per year worldwide. Mechanical failures of intertrochanteric nailing in IFFs could be managed with revision total hip arthroplasty (THA). AIM To describe the surgical complexity and the procedure-related complication rates in patients with trochanteric nailing failure and treated with THA. METHODS Patients referred to our level I trauma center between April 2012 and July 2018 with failed cephalomedullary nailing following trochanteric fractures were retrospectively recruited. All patients underwent a salvage surgical procedure, i.e., cephalomedullary nail removal and conversion to THA. The same surgical and anesthesiology team performed the surgical procedures under spinal anesthesia. All patients underwent clinical and radiographic follow-ups for at least 24 mo. Complications and re-operations were recorded. RESULTS Seventy-four patients met the inclusion criteria (male: 29; female: 45; mean age: 73.8-years-old; range: 65-89) and were included in the current study. The average operative time was 117 min (76-192 min). The average blood loss was 585 mL (430-1720 mL). Among the 74 patients, 43 (58.1%) required transfusion of three or more blood units. Two patients died within the 4th d after surgery because of pulmonary embolism, and 1 patient died 9 mo after surgery due to ischemic myocardial infarction. The complication rate in the 71 patients who completed the minimum 24-mo follow-up was 22.5%. In 3 cases out of 71 (4.2%) periprosthetic acetabular fracture was observed during the follow-up. One of these periacetabular fractures occurred intraoperatively. An intraoperative periprosthetic femur fracture was observed in 5 patients out of 71 (7.0%). Four of these patients needed a re-operation to fix the fracture with plates and cerclages; in one of these patients, femoral stem revision was also necessary. In 4 patients out of 71 (5.6%), an early THA dislocation was observed, whereas in 1 case (1.4%) a late THA dislocation was observed. Three patients out of 71 (4.2%) developed a periprosthetic joint infection during the study follow-up. CONCLUSION The present study demonstrated that salvage options for IFF fixation failure are complex procedures with a relevant intraoperative and postoperative complication rate.

Abstract
INTRODUCTION Hip fractures are common injuries in the elderly and are usually treated with timely surgery. While severe postoperative complications are reported for up to 10% of patients, many studies identified predictive factors for the occurrence of complications postoperatively. A controversially discussed factor is "time-to-surgery". The aim of the study was to examine if time-to-surgery was associated with the occurrence of complications and if the complication rate differed between the patient individual fracture types of intracapsular on the one hand and extracapsular hip fractures on the other hand. We hypothesized that time-to-surgery had less impact on complications in intracapsular hip fractures compared to extracapsular ones, and therefore, guidelines should pay attention to the patient individual case scenario. MATERIALS AND METHODS All patients who were admitted to the Department of Trauma and Orthopaedic Surgery of an academic teaching hospital for hip fracture surgery (n = 650) over a five-year period were included in the study. After the application of the exclusion criteria, such as periprosthetic or pathologic fractures, cases needed immediate surgical treatment, and after outlier adjustment, 629 cases remained in the study. Hip fractures were classified into intracapsular fractures (treated by hip arthroplasty) and extracapsular fractures (treated by intramedullary nailing osteosynthesis). The occurrence of severe complications in patients treated within 24 h was compared with patients treated later than 24 h after injury. For statistical evaluation, a multivariate logistic regression analysis was performed to investigate the impact of time-to-surgery interval on the occurrence of complications. RESULTS Patients with an extracapsular fracture, which was treated with intramedullary nailing (44.5%), rarely suffered a serious complication when surgery was performed within 24 h after injury. However, when the interval of the time-to-surgery was longer than 24 h, the complication rate increased significantly (8.63% vs. 25.0%, p = 0.002). In contrast to this finding in patients with intracapsular fractures (55.5%), which were treated with cemented arthroplasty, complication rates did not depend on the 24 h interval (26.17% vs. 20.83%, p = 0.567). CONCLUSIONS The occurrence of complications after surgical treatment of hip fractures is associated with the time interval between injury and surgery. A 24 h time interval between injury and surgical procedure seems to play a major role only in extracapsular fractures treated with osteosynthesis but not in intracapsular fractures treated with arthroplasty. Therefore, guidelines should take notice of the patient individual case scenario and, in particular, the individual hip fracture type.

BMC Musculoskelet Disord 2023; 24:787. [PMID: 37794410 PMCID: PMC10548656 DOI: 10.1186/s12891-023-06892-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Accepted: 09/16/2023] [Indexed: 10/06/2023] Open
Abstract
INTRODUCTION Fragility fractures around the proximal end of the femur have increased in recent years due to an aging population, adding to the pressure on national health care systems and to hospital expenses. Peri-trochanteric fractures have historically been treated successfully with anatomic intramedullary nails, giving stable fixation in order to allow early for mobilisation of these frail patients. Some of these nails allow a second (anti-rotational) screw through the nail into the femoral head. We assessed the use of this additional screw in terms of quality of reduction, post-operative mobilization and complications. MATERIALS & METHODS All patients who were treated in the same hospital for peri-trochanteric fracture between January 2017 and December 2019 were included in the study. The patients were randomly assigned into group A, where the treatment included intramedullary nailing using one femoral hip screw, and group B, where the treatment additionally included a second anti-rotational screw. The patients were followed up clinically and radiologically, for at least 3 months post-operatively. Demographic and operative data were collected alongside radiographic and clinical data. RESULTS A total of 118 patients with an average age of 82.7 years were included in the study after exclusion criteria was applied. There were no statistically significant differences between the two groups regarding the ASA grade, Nottingham Hip fracture score, Koval score, Mental score, operation time, transfusion requirements, and operative radiation dose and time (p > 0.05). In group A, more complications were observed (p < 0.05). The radiographic measurements were statistically significantly different. CART analysis revealed that the use of a single screw in the femoral head for the subgroup of the unstable peri-trochanteric fractures (Jensen Type 4-5 - AO31A2.2 and above), has a tendency toward developing more post-operative complications, though this was not statistically significant. CONCLUSION The use of an additional anti-rotational screw for unstable peri-trochanteric fractures (Jensen Type 4-5 and AO 31A2.2 and above) could prevent complications such as varus collapse and cut-out.

Abstract
BACKGROUND A bony Bankart lesion directly affects the stability of the shoulder by reducing the glenoid joint-contact area. The aim of this study was to report on the epidemiological data relating to bony Bankart lesions in Sweden using the Swedish fracture register. The purpose is to evaluate age and sex distribution in the population with bony Bankart lesions, its impact on treatment strategy and further to analyse patient-reported outcomes. METHODS This was an epidemiological descriptive study. The inclusion criteria were all patients with a unilateral bony Bankart lesion registered between April 2012 and April 2019. The patients' specific data (age, sex, type and time of injury, treatment option and patient-reported outcomes) were extracted from the Swedish fracture register database. RESULTS A total of 790 unilateral bony Bankart fractures were identified. The majority of the patients were male (58.7%). The median age for all patients at the time of injury was 57 years. Females had a higher median age of 66 years, compared with males, 51 years. Most of the bony Bankart lesions, 662 (91.8%), were registered as a low-energy trauma. More than two-thirds of all treatment registered cases, 509/734 patients (69.3%), were treated non-surgically, 225 (30.7%) were treated surgically, while, in 17 patients (7.5% of all surgically treated patients), the treatment was changed from non-surgical to surgical due to recurrent instability. Surgical treatment was chosen for 149 (35%) of the males and for 76 (25%) of the females. Patient quality of life decreased slightly in both surgically and non-surgically treated groups 1 year after bony Bankart injury. CONCLUSION This national register-based study provides detailed information on the epidemiology, choice of treatment and patient-reported outcomes in a large cohort of bony Bankart lesions. Most bony Bankart lesions affected males between 40 and 75 years after low-energy falls and non-surgical treatment dominated.

Abstract
BACKGROUND Patients with critical illness have a high risk of mortality. Key decision-making in the health system affecting the outcomes of critically ill patients requires epidemiological evidence, but the burden of critical illness is largely unknown. This study aimed to estimate the prevalence of critical illness in a Swedish region. Secondary objectives were to estimate the proportion of hospital inpatients who are critically ill and to describe the in-hospital location of critically ill patients. METHODS A prospective, multi-center, population-based, point-prevalence study on specific days in 2017-2018. All adult (> 18 years) in-patients, regardless of admitting specially, in all acute hospitals in Sörmland, and the patients from Sörmland who had been referred to university hospitals, were included. Patients in the operating theatres, with a psychiatric cause of admission, women in active labor and moribund patients, were excluded. All participants were examined by trained data collectors. Critical illness was defined as "a state of ill health with vital organ dysfunction, a high risk of imminent death if care is not provided and a potential for reversibility". The presence of one or more severely deranged vital signs was used to classify critical illness. The prevalence of critical illness was calculated as the number of critically ill patients divided by the number of adults in the region. RESULTS A total of 1269 patients were included in the study. Median age was 74 years and 50% of patients were female. Critical illness was present in 133 patients, resulting in an adult population prevalence of critical illness per 100,000 people of 19.4 (95% CI 16.4-23.0). The proportion of patients in hospital who were critically ill was 10.5% (95% CI 8.8-12.3%). Among the critically ill, 125 [95% CI 94.0% (88.4-97.0%)] were cared for in general wards. CONCLUSIONS The prevalence of critical illness was higher than previous, indirect estimates. One in ten hospitalized patients were critically ill, the large majority of which were cared for in general wards. This suggests a hidden burden of critical illness of potential public health, health system and hospital management significance.

World J Psychiatry 2023; 13:533-542.

Abstract
BACKGROUND As the perioperative risk of elderly patients with extremely unstable hip fractures (EUHFs) is relatively high and therapeutic effect is not satisfactory, new thera-peutic strategies need to be proposed urgently to improve the efficacy and clinical outcomes of such patients. AIM To determine the influence of two surgical treatment modalities on postoperative cognitive function (CF) and delirium in elderly patients with EUHFs. METHODS A total of 60 elderly patients consecutively diagnosed with EUHF between September 2020 and January 2022 in the Chongqing University Three Gorges Hospital were included. Of them, 30 patients received conventional treatment (control group; general consultation + fracture type-guided internal fixation), and the other 30 received novel treatment (research group; perioperative multidisciplinary treatment diagnosis and treatment + individualized surgical plan + risk prediction). Information on hip function [Harris hip score (HHS)], perioperative risk of orthopedic surgery [Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM)], CF [Montreal cognitive assessment scale (MoCA)], postoperative delirium [mini-cognitive (Mini-Cog)], adverse events (AEs; internal fixation failure, infection, nonunion, malunion, and postoperative delirium), and clinical indicators [operation time (OT), postoperative hospital length of stay (HLOS), ambulation time, and intraoperative blood loss (IBL)] were collected from both groups for comparative analyses. RESULTS The HHS scores were similar between both groups. The POSSUM score at 6 mo after surgery was significantly lower in the research group compared with the control group, and MoCA and Mini-Cog scores were statistically higher. In addition, the overall postoperative complication rate was significantly lower in the research than in the control group, including reduced OT, postoperative HLOS, ambulation time, and IBL. CONCLUSION The new treatment modality has more clinical advantages over the conventional treatment, such as less IBL, faster functional recovery, more effectively optimized perioperative quality control, improved postoperative CF, mitigated postoperative delirium, and reduced operation-related AEs.

Abstract
Reduced muscle mass and/or strength are risk factors for metabolic and musculoskeletal impairment. The present study evaluated anthropometric, metabolic, and musculoskeletal outcomes in females with and without sarcopenic-obesity parameters who underwent bariatric surgery during a 1-year follow-up. A prospective, single-center cohort study was conducted in females with obesity undergoing preoperative evaluation for surgery. In the preoperative period, females were allocated into obesity with sarcopenic-obesity parameters (SOP group, n = 15) and without sarcopenic-obesity parameters (obesity group, n = 21). Sarcopenic obesity parameters were defined as lower appendicular skeletal mass adjusted for weight (ASM/wt) and/or low handgrip strength (HGS). Anthropometric, metabolic, and musculoskeletal parameters were assessed before surgery and at 3 months, 6 months, and a 1-year after bariatric surgery. Weight loss was similar between groups (p > 0.05). Weight, body mass index, fat mass, body fat percentage, skeletal muscle mass, fat-free mass, fat-free mass index, HGS were reduced in both groups during the 1-year follow-up (p < 0.05). However, when muscle mass and strength were analyzed relative to body size, an improvement after bariatric surgery was found in both groups (p < 0.05). Total cholesterol, LDL-c, triglycerides, fasting glucose, glycated hemoglobin, insulin, and insulin resistance were reduced in both groups during the 1-year follow-up (p < 0.05). In addition, HDL-c serum concentration increased in females with and without sarcopenic-obesity parameters over the 1-year follow-up (p < 0.05). Both groups had decreased bone mineral density (BMD) at all sites (lumbar spine, femoral neck, and total femur) over the 1-year follow-up (p < 0.05). The highest quartile of ASM/wt was positively associated with BMD variables in a longitudinal analysis, suggesting that preserved ASM/wt in pre-surgery may be beneficial for BMD after 1 year of bariatric surgery. The results showed that bariatric surgery promotes similar musculoskeletal and metabolic changes in females with preserved muscle mass and strength or in females with sarcopenia-related parameters.

Abstract
A traumatic femur fracture is a significant cause of morbidity, affecting one to three million individuals annually. The present is the first study investigated the epidemiological characteristics, risk factors, classification, mechanisms of injury, and early management of femoral fractures in Somalia. This retrospective epidemiological study included all patients with a femur fracture who were admitted for four years between November 2018 and December 2022 to the orthopedic and trauma surgery department. We reviewed patient demographic characteristics, including age and gender, the mechanism of injury, injury characteristics, and the type of fixation performed. We reviewed the radiographs and classified the fracture using the AO/OTA classification system. During the study period, a total of 402 patients were treated for femur fractures; 256 (64%) were males, and 144 (36%) were females. The mean patient age was 47.7 ± 8.5 years. Regarding the anatomical location of femur fractures, the proximal (31A, 31B) was the most common, accounting for 50% of the patients. Femur neck fracture (31B) was the most common in the proximal femur fractures. Gunshot 82 (59.42%) was the leading cause of femur shaft fractures. Most patients with femur shaft fractures were males; 150 (86.20%) and 152 (64.47%) were young patients between 19 and 40 years old. Almost half of the patients (86) with femur shaft fractures had open fractures. The distribution of the mechanism of injury significantly differed according to age (p < 0.001). Younger patients (< 40 years) were predominantly injured due to gunshot injuries compared to elderly cases (> 60 years), where falls from standing height were the primary mechanism of injuries. There was a statistically significant difference between the mechanism of injury and gender categories (p < 0.001). Male patients were injured mainly by gunshots in about 40%, while 80% of fractures in female patients were due to falls from standing height. Female fractures occurred primarily in the proximal, while the males had an equal fracture rate for proximal and shaft fractures. Femur fracture causes significant morbidity and mortality. The study findings revealed that the most common femur fracture type was femur neck fracture, and low-energy injuries were the most common mode of injury in the elderly. Proximal femur fractures occur in older age and mainly in females. Gunshots were the most common cause of femur shaft fractures in Somalia, a country that has struggled with wars for over 30 years.

Abstract
Amongst hip fracture admissions, mortality is higher in men than in women. However, sex differences in other care-quality measures have not been well-documented. We aimed to examine sex differences in mortality as well as a wide range of underlying health indicators and clinical outcomes in adults ≥ 60 year of age admitted with hip fractures from their own homes to a single NHS hospital between April-2009 and June-2019. Sex differences in delirium, length of stay (LOS) and mortality in hospital, readmission, and discharge destination, were examined by logistic regression. There were 787 women and 318 men of similar mean age (± SD): 83.1 year (± 8.6) and 82.5 year (± 9.0), respectively (P = 0.269). There were no sex differences in history of dementia or diabetes, anticholinergic burden, pre-fracture physical function, American Society of Anesthesiologists grades, or surgical and medical management. Stroke and ischaemic heart disease, polypharmacy, and alcohol consumption were more common in men. After adjustment for these differences and age, men had greater risk of delirium (with or without cognitive impairment) within one day of surgery: OR = 1.75 (95%CI 1.14-2.68), LOS ≥ 3 weeks in hospital: OR = 1.52 (1.07-2.16), mortality in hospital: OR = 2.04 (1.14-3.64), and readmission once or more after 30 days of a discharge: OR = 1.53 (1.03-2.31). Men had a lower risk of a new discharge to residential/nursing care: OR = 0.46 (0.23-0.93). The present study revealed that, in addition to a greater risk of mortality than women, men also had many other adverse health outcomes. These findings, which have not been well-documented, serve to stimulate future targeted preventive strategies and research.

Abstract
BACKGROUND Hip fractures are a major public health problem worldwide and can lead to disability, increased mortality, and reduced quality of life. We aim to provide a nationwide epidemiological analysis of trochanteric and subtrochanteric fractures and their respective surgical treatments. METHODS Data were retrieved from the national database of the German Department of the Interior. ICD-10-GM and OPS data from the period of 2006 to 2020 were analysed and all patients with trochanteric and subtrochanteric fractures as their main diagnosis, who were treated in a German hospital, were included. Patients were grouped by age and gender and linear regression was performed where suitable to calculate statistically significant correlations between variables and incidences. RESULTS 985,104 pertrochanteric fractures and 178,810 subtrochanteric fractures were reported during the analysed period. We calculated a mean incidence of 80.08 ± 6.34 for pertrochanteric and 14.53 ± 1.50 for subtrochanteric fractures per million inhabitants. In both fracture types, a distinct dependence of incidence on age can be determined. Incidence rates equally rise in both sexes through the age groups with an increase of about 288-fold from those under the age of 60 to those over the age of 90 in pertrochanteric fractures, and about 123-fold in subtrochanteric fractures. Intramedullary nailing was the most common kind of treatment for both fracture types with augmentative cerclages on the rise throughout the whole period. Plate and dynamic compression screws were decreasing in frequency over the analysed period in both fractures. CONCLUSIONS We provided incidence data on per- and subtrochanteric fractures and their treatment. We calculated an economic impact of approximately 1.563 billion € per year in Germany. With regards to recent literature on costs of treatment and our findings regarding the implementation and utilization of different treatment methods, we conclude that the reinforcement of nationwide prevention programs is a relevant step in lessening the economic burden. We welcome the increased utilisation of intramedullary nailing as many studies show beneficiary outcomes and cost effectiveness in most of the included fracture types.

Predictive Value of the C-Reactive Protein to Albumin Ratio in 30-Day Mortality after Hip Fracture in Elderly Population: A Retrospective Observational Cohort Study. J Clin Med 2023; 12:4544. [PMID: 37445579 DOI: 10.3390/jcm12134544] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2023] [Revised: 06/29/2023] [Accepted: 06/30/2023] [Indexed: 07/15/2023] Open
Abstract
BACKGROUND C-reactive protein (CRP) to Albumin ratio (CAR) has been used in multiple clinical settings to predict early mortality. However, there is a lack of evidence on the predictive role of CAR in 30-day mortality after a hip fracture. The purpose of this study was to establish a potential association between CAR and 30-day mortality and to assess if the CAR Receiving Operating Characteristics curve (ROC) can be a reliable predictor of early mortality. METHODS We retrospectively reviewed the charts of 676 patients (>65 years) treated for hip fracture between 2006 and 2018. All hip fractures were included. Treatment strategies included closed reduction and internal fixation, open reduction and internal fixation, hemiarthroplasty, or total joint arthroplasty. Statistical analysis included T-test, Pearson correlation for CAR and other markers, ROC curves and area under the curve, Youden Model, and Odds Ratio. RESULTS The 30-day mortality rate analysis showed that higher preoperative levels of CAR were associated with higher early mortality. When analyzing the area under the ROC curve (AUROC) for 30-day mortality, the reported value was 0.816. The point of the ROC curve corresponding to 14.72 was considered a cut-off with a specificity of 87% and a sensibility of 40.8%. When analyzing values higher than 14.72, the 30-day mortality rate was 17.9%, whilst, for values lower than 14.72, the 30-day mortality rate was 1.8%. CONCLUSIONS Patients older than 65 years affected by a hip fracture with increased preoperative levels of CAR are associated with higher 30-day mortality. Despite a moderate sensibility, considering the low cost and the predictivity of CAR, it should be considered a standard predictive marker.

Inverse relationship between femoral lateralization and neck-shaft angle is a joint event after intramedullary nailing of per trochanteric fractures. Sci Rep 2023; 13:10999. [PMID: 37419961 PMCID: PMC10328961 DOI: 10.1038/s41598-023-38209-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2023] [Accepted: 07/05/2023] [Indexed: 07/09/2023] Open
Abstract
This study explored the relationship between femoral lateralization and femoral neck-shaft angle after intramedullary nail (IM) fixation for per trochanteric fractures. 70 patients (AO/OTA 31A1-2) were investigated. Anteroposterior (AP) and lateral X-ray views pre- and post-operation were recorded. Patients were classified into three groups according to the position of the medial cortex of the head-neck fragment to that of the femoral shaft: being slightly superomedial (positive medial cortex support, PMCS), being smoothly contacted (neutral position, NP) or being displaced laterally (negative medial cortex support, NMCS). Patient demographics, femoral lateralization, and neck-shaft angle were measured and statistically analyzed pre- and post-operation. Functional recovery was evaluated by Harris score 3- and 6- months post-operation. All cases ultimately demonstrated radiographic fracture union. There was a tendency to have an increased neck-shaft angle (valgus alignment) in the PMCS group and increased femoral lateralization in the NP group (p < 0.05). Among those three groups, the change in femoral lateralization and neck-shaft angle was statistically different (p < 0.05). An inverse relationship between femoral lateralization and femoral neck-shaft angle was observed. Femoral lateralization increased correspondingly when the neck-shaft angle continuously decreased from the PMCS group to the NP group and then to the NMCS group, and patients in the PMCS group had better functional recovery than the other two groups (p < 0.05). Femoral lateralization was commonly produced after IM fixation for per trochanteric fractures. The fracture fixed in PMCS mode possesses the slightest change in femoral lateralization while maintaining valgus alignment of the femoral neck-shaft angle and good functional outcome, which is superior to NP or NMCS mode.

Abstract
Background Hip fractures in amputees pose a significant challenge for the orthopedic surgeon due to technical difficulties and there is no standardisation in their management. Their treatment is consequently left to the surgeon's ingenuity. The aim of this study is to describe the clinical characteristics and outcome of a series of hip fractures in lower limb amputees. Methods A total of 12 patients and 15 hip fractures in lower limb amputees were included. Amputations below the malleoli and prosthetic surgery due to osteoarthritis constitute the exclusion criteria. Demographic, amputation-related and fracture data as well as radiological, functional, and clinical outcomes were collected through the patients' medical records. Results Age at fracture and at amputation were different depending on the cause of amputation. Most patients (10/12) were male. Seven patients had an infracondylar amputation and five patients had a supracondylar amputation. Ten hip fractures were on the same side of the amputation, three were contralateral and one was bilateral. Pertrochanteric (6/15) and subcapital (5/15) were the main types observed. Different traction methods and surgical procedures were used. We observed no significant differences in terms of outcome regardless of the fracture, traction method, and surgical management. No complications related to surgery or during follow-up were found. Mortality at one year postoperatively was absent. Conclusion Provided an experienced orthopaedic surgeon, a pre-operative assessment, a comprehensive surgical planning, and a multidisciplinary rehabilitation strategy are present; a satisfactory outcome is to be expected.

Abstract
Objectives This was a prospective, randomized controlled trial to test functional outcomes between a single lag screw and helical blade nails in the treatment of intertrochanteric fractures. Methods 72 patients with intertrochanteric fractures between March 2019 to November 2020 were randomized into two groups and treated with a lag screw or a helical blade nail. Intraoperative parameters such as operative time, blood loss, and radiation exposure were calculated. Postoperatively, tip apex distance, neck length, neck-shaft angle, lateral impingement of implant, union rate, and the functional outcomes were measured at the end of 6 month follow-up period. Results There was a significant decrease in tip apex distance (p = 0.03) and neck length(p-0.04) with significant lateral impingement of the implant (p = 0.04) in the helical blade group compared to the lag screw group. The functional outcome calculated using the modified Harris Hip score & Parker and Palmer mobility score, at the end of 6 months, had no significant difference between the two groups. Conclusion Both lag screw and helical blade devices can be used to successfully treat these fractures, although there is greater medial migration in the helical blade as compared to the lag screw.

Results From and Additional Analysis of the Global Burden of Disease Study 2019. Clin Orthop Relat Res 2023; 481:1209-1220. [PMID: 36374576 PMCID: PMC10194687 DOI: 10.1097/corr.0000000000002465] [Citation(s) in RCA: 18] [Impact Index Per Article: 18.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Accepted: 09/29/2022] [Indexed: 11/16/2022]
Abstract
BACKGROUND Hip fractures are associated with a high risk of death; among those who survive a hip fracture, many experience substantial decreases in quality of life. A comprehensive understanding of the epidemiology and burden of hip fractures by country, age, gender, and sociodemographic factors would provide valuable information for healthcare policymaking and clinical practice. The Global Burden of Disease (GBD) study 2019 was a global-level study estimating the burden of 369 diseases and injuries in 204 countries and territories. An exploration and additional analysis of the GBD 2019 would provide a clearer picture of the incidence and burden of hip fractures. QUESTIONS/PURPOSES Using data from the GBD 2019, we asked, (1) What are the global, regional, and national incidences of hip fractures, and how did they change over a recent 30-year span? (2) What is the global, regional, and national burden of hip fractures in terms of years lived with disability, and how did it change over that same period? (3) What is the leading cause of hip fractures? (4) How did the incidence and years lived with disability of patients with hip fractures change with age, gender, and sociodemographic factors? METHODS This was a cross-sectional study. Participant data were obtained from the GBD 2019 ( http://ghdx.healthdata.org/gbd-results-tool ). The GBD study is managed by the WHO, coordinated by the Institute of Health Metrics and Evaluation, and funded by the Bill and Melinda Gates Foundation. It estimates the burden of disease and injury for 204 countries by age, gender, and sociodemographic factors, and can serve as a valuable reference for health policymaking. All estimates and their 95% uncertainty interval (UI) were produced using DisMod-MR 2.1, a Bayesian meta-regression tool in the GBD 2019. In this study, we directly pulled the age-standardized incidence rate and years lived with disability rate of hip fractures by location, age, gender, and cause from the GBD 2019. Based on these data, we analyzed the association between the incidence rate and latitude of each country. Then, we calculated the estimated annual percentage change to represent trends from 1990 to 2019. We also used the Spearman rank-order correlation analysis to determine the correlation between the incidence or burden of hip fractures and the sociodemographic index, a composite index of the income per capita, average years of educational attainment, and fertility rates in a country. RESULTS Globally, hip fracture incidences were estimated to be 14.2 million (95% UI 11.1 to 18.1), and the associated years lived with disability were 2.9 million (95% UI 2.0 to 4.0) in 2019, with an incidence of 182 (95% UI 142 to 231) and 37 (95% UI 25 to 50) per 100,000, respectively. A strong, positive correlation was observed between the incidence rate and the latitude of each country (rho = 0.65; p < 0.001). From 1990 to 2019, the global incidence rate for both genders remained unchanged (estimated annual percentage change 0.01 [95% confidence interval -0.08 to 0.11]), but was slightly increased in men (estimated annual percentage change 0.11 [95% CI 0.01 to 0.2]). The years lived with disability rate decreased slightly (estimated annual percentage change 0.66 [95% CI -0.73 to -0.6]). These rates were standardized by age. Falls were the leading cause of hip fractures, accounting for 66% of all patients and 55% of the total years lived with disability. The incidence of hip fractures was tightly and positively correlated with the sociodemographic index (rho 0.624; p < 0.001), while the years lived with disability rate was slightly negatively correlated (rho -0.247; p < 0.001). Most hip fractures occurred in people older than 70 years, and women had higher incidence rate (189.7 [95% UI 144.2 to 247.2] versus 166.2 [95% UI 133.2 to 205.8] per 100,000) and years lived with disability (38.4 [95% UI 26.9 to 51.6] versus 33.7 [95% UI 23.1 to 45.5] per 100,000) than men. CONCLUSION Hip fractures are common, devastating to patients, and economically burdensome to healthcare systems globally, with falls being the leading cause. The age-standardized incidence rate has slightly increased in men. Many low-latitude countries have lower incidences, possibly because of prolonged sunlight exposure. Policies should be directed to promoting public health education about maintaining bone-protective lifestyles, enhancing the knowledge of osteoporosis management in young resident physicians and those in practice, increasing the awareness of osteoporosis screening and treatment in men, and developing more effective antiosteoporosis drugs for clinical use. LEVEL OF EVIDENCE Level III, prognostic study.

Abstract
OBJECTIVE Describe rates of hip fracture-related emergency department (ED) visits, hospitalizations, and deaths among older adults (aged ≥65 years) in the United States. METHODS Data from the 2019 Healthcare Cost and Utilization Project and National Vital Statistics System were used to calculate rates of hip fracture-related ED visits, hospitalizations, and deaths among older adults by select characteristics and mechanism of injury. RESULTS In 2019, there were 318,797 ED visits, 290,130 hospitalizations, and 7731 deaths related to hip fractures among older adults. About 88% of ED visits and hospitalizations and approximately 83% of deaths related to hip fractures were caused by falls. Rates were highest among older adults living in rural areas and among those aged ≥85 years. DISCUSSION Most hip fractures among older adults are fall-related. Healthcare providers can prevent falls among their older patients by screening for fall risk, assessing modifiable risk factors, and offering evidence-based interventions.

Abstract
OBJECTIVES Oral anticoagulation (OAC) may have an impact on mortality in cases hospitalized for hip fracture (HF). We studied nationwide time trends of OAC prescriptions and compared time trends of inhospital mortality of HF cases with and without OAC in Germany DESIGN: Retrospective cohort study SETTING: Nationwide German hospitalization, Diagnosis-Related Groups Statistic PATIENTS/PARTICIPANTS: All hospital admissions for HF 60 years and older in the years 2006 through 2020. INTERVENTION Additional diagnosis with a personal history of long-term use of anticoagulants (ICD code Z92.1). MAIN OUTCOME MEASUREMENTS Inhospital mortality RESULTS: Cases hospitalized for HF 60 years and older increased by 29.5%. In 2006, 5.6% had a documented history of long-term use of OACs. This proportion rose to 20.1% in 2020. Age-standardized hospitalization mortality in HF cases without long-term use of OACs in males decreased steadily from 8.6% (95% confidence intervals 8.2 - 8.9) in 2006 to 6.6% (6.3 - 6.9) in 2020 and in females from 5.2% (5.0 - 5.3) to 3.9% (3.7 - 4.0). Mortality of HF cases with long-term use of OACs remained unchanged: males 7.0% (5.7 - 8.2) in 2006 and 7.3% (6.7 - 7.8) in 2020, females 4.8% (4.1 - 5.4) and 5.0% (4.7 - 5.3). CONCLUSION Inhospital mortality of HF cases with and without long-term OAC show different trends. In HF cases without OAC, mortality decreased from 2006 to 2020. In cases with OAC such a decrease could not be observed.

Abstract
Although the incidence of proximal femur fractures (PFFs) is increasing, few detailed reports on associated long-term outcomes and causes of death exist. We aimed to evaluate long-term outcomes and causes of death ≥5 years after surgical treatment of PFFs. This retrospective study included 123 patients (18 males, 105 females) with PFFs treated at our hospital between January 2014 and December 2016. Cases (median age: 90 [range, 65-106] years) comprised 38 femoral neck fractures (FNFs) and 85 intertrochanteric fractures (IFs). Surgical procedures included bipolar head arthroplasty (n = 35), screw fixation (n = 3), and internal fixation with nails (n = 85). The mean post-surgical follow-up time was 58.9 (range, 1-106) months. Surveyed items included survival (1 vs 5 years; sex; age, >90 vs <90 years; IF vs FNF), comorbidities, waiting time after the injury (died vs survived), operative time (proximal femoral nail antirotations [PFNA] vs FNF, died vs Survived), blood loss (PFNA vs FNF; died vs survived), and cause of death (IF vs FNF; <1 vs >1 year). Among all patients, 83.7% had comorbidities (IF, 90.5%; FNF, 81.5%). Among patients who died and survived, 89.1% and 80.5% had comorbidities, respectively. The most common comorbidities were cardiac (n = 22), renal (n = 10), brain (n = 8), and pulmonary (n = 4) diseases. Overall survival (OS) rates at 1 and 5 years were 88.9% and 66.7%, respectively. Male/female OS rates were 88.8%/88.3% and 66.6%/66.6% (P = .89) at 1 and 5 years, respectively. OS rates for the <90/≥90 age groups were 90.1%/76.7% and 75.3%/53.4 (P < .01) at 1 and 5 years, respectively. The 1- and 5-year OS (IF/FNF) rates were 85.7%/88.8% and 60%/81.5%, respectively; patients with IFs had significantly lower OS than those with FNFs at both timepoints (P = .015). There was a marked difference in the operative time between died (43.5 ± 24.0: mean ± S.D.) and survived (60 ± 24.4: mean ± S.D.) patients. The main causes of death were senility (n = 10), aspiration pneumonia (n = 9), bronchopneumonia (n = 6), worsening heart failure (n = 5), acute myocardial infarction (n = 4), and abdominal aortic aneurysm (n = 4). Overall, 30.4% of the cases were related to comorbidities and related causes (e.g., hypertension-related ruptured large abdominal aneurysm). Managing comorbidities may improve long-term postoperative outcomes of PFF treatment.

Gasparik AI, Lorenzovici L, Pașcanu IM, Csata Z, Poiană C, Dobre R, Bartelick MM. Predictors of mortality for patients with hip fracture: a study of the nationwide 1-year records of 24,950 fractures in Romania. Arch Osteoporos 2023; 18:69. [PMID: 37195371 DOI: 10.1007/s11657-023-01253-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Accepted: 04/19/2023] [Indexed: 05/18/2023]
Abstract
We conducted a study evaluating incidence rates and influencing factors in Romanian hip fracture patients. Our results showed that the type of fracture and its respective surgical procedure as well as hospital characteristics correlate with mortality. Updated incidences can result in updated treatment guidelines. PURPOSE The aim of our study was to assess incidence rates for a revision-calibration of the Romanian FRAX tool and to evaluate particularities of hip fracture cases to determine patient- and hospital-related variables affecting mortality. METHODS We conducted a retrospective study using hospital reports of hip fracture codes to the National School of Statistics (NSS) from January 1, 2019, until December 31, 2019. The study population included 24,950 patients presenting to Romanian public hospitals in all 41 counties: ≥ the age of 40 with diagnostic ICD 10 codes: S72.0 femoral neck fracture, S72.1 pertrochanteric femoral fracture, and S72.2 subtrochanteric femoral fracture and procedure codes: O11104 (trochanteric/sub capital internal fixation), O12101 (hemiarthroplasty), O11808 (closed femoral reduction with internal fixation), O12103 (partial arthroplasty), O12104 (total arthroplasty). Hospital length of stay (LoS) was classified as follows: < 6, 6-9, 10-14, and ≥ 15 days. RESULTS Incidence of hip fractures was 248/100,000 among those aged 50 + and 184/100,000 within the 40 + age category. Average age of the patients was 77 years (80 for females, 71 for males); 83.7% of the patients were 65 + with equivalent urban-rural distributions. Males had a 1.7 times higher mortality risk. Each year increase in age added a mortality risk of 6.9%. In-hospital mortality was 1.34 times higher among patients living in urban areas. Hemiarthroplasty and partial/total unilateral/bilateral arthroplasty had a lower risk of mortality than trochanteric/sub capital internal fixation (p < 0.02, p < 0.033). CONCLUSION Gender, age, residence, and procedure type had significant impact on mortality. Updated incidence rates will allow the revision of Romania's FRAX model.

Abstract
OBJECTIVE To evaluate the intraobserver and interobserver reliability of the 2018 OTA/AO trochanteric hip fracture (THF) classification compared with the 1983 OTA/AO Muller classification system. To further delineate the reliability of classifying stable and unstable THF using the 2 classification systems. DESIGN Radiographic observational study. SETTING Multicenter, one Level 1 and one Level 2 trauma centers. PARTICIPANTS/PATIENTS Seventy-three radiographic series of patients treated operatively for THF were evaluated by 6 orthopaedic surgeons. INTERVENTION The OTA/AO THF classification system was applied by each surgeon to 73 cases in 2 independent assessments performed 4 weeks apart: once by the old classification followed by the new 2018 OTA/AO classification. Each radiographic series included lateral hip and anteroposterior initial radiographs. Eight random cases were duplicated in each of the surveys to evaluate the intraobserver reliability. MAIN OUTCOME MEASUREMENTS Intraobserver and interobserver of the group, subgroup and fracture stability classification determined by the interclass coefficient (ICC) and Cohen kappa values. RESULTS The interobserver reliability for the group classification (31A1/A2/A3) was moderate using the new classification, whereas substantial agreement was shown using the old classification (0.49 and 0.69, respectively). The reliability of the fracture stability classification was higher using the old classification (0.70 vs. 0.52). Subgroup classifications interobserver agreement was fair for both classification systems, although lower reliability was shown in the old classification (0.34 vs. 0.31). CONCLUSIONS The new OTA/AO classification has a lower interobserver reliability for THF classification when compared with the old one.

Mortality in patients with trochanteric hip fractures (AO/OTA 31-A) treated with sliding hip screw versus intramedullary nail: A retrospective national registry study of 9547 patients from the Danish Fracture Database. Injury 2023:S0020-1383(23)00249-8. [PMID: 36925374 DOI: 10.1016/j.injury.2023.03.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/26/2022] [Revised: 03/01/2023] [Accepted: 03/06/2023] [Indexed: 03/18/2023]
Abstract
BACKGROUND Whether trochanteric hip fractures (AO/OTA 31-A) should be treated with an intramedullary nail (IMN) or sliding hip screw (SHS) is debated. Recent studies suggest an association between IMN and excess mortality rates compared to SHS, but higher quality studies fail to show this association. Furthermore, there is an increased usage of IMN with sparse evidence supporting this rise. Our aim was to compare mortality rates between IMN and SHS in patients with AO/OTA 31-A fractures. Secondarily, to investigate choice of implant in relation to fracture subtype. METHODS This national registry study is based on data from the Danish Fracture Database (DFDB). Data were retrieved on patients aged ≥65 years treated for a non-pathological AO/OTA type 31-A fracture with IMN or SHS from January 1, 2012 to December 31, 2018. Data from DFDB were merged with data from the Danish Civil Registration System (CRS) for time of death. Mortality rates were recorded at 30 days, 90 days, and 1 year and presented as crude mortality and adjusted for age, gender, ASA-class, and AO/OTA-subtype. RESULTS A total of 9,547 patients were included. The mean age was 83 years, 69% were female, and 55% were ASA-class 3-5. We found higher mortality rates for IMN-patients at 30 days, 90 days, and 1 year. The crude relative mortality risk for IMN was also significantly higher at both 30 days (1.20) and 90 days (1.11). Adjusted relative mortality risk for IMN was 1.12 [0.96; 1.31] at 30-days, 1.03 [0.91; 1.17] at 90-days, and 1.01 [0.92; 1.11] at 1 year. Most patients suffered a 31-A2 fracture (56%) and, overall, 74% of patients were treated with IMN. CONCLUSION We found significantly increased crude relative mortality risk at 30 days and 90 days in patients treated with IMN. However, when adjusting for confounders the two groups had similar mortality risks. In total, 74% of all patients in this cohort were treated with IMN. LEVEL OF EVIDENCE This study has level of evidence: III.

Abstract
BACKGROUND AND PURPOSE Hip fractures should be treated based on the best available evidence and cost-effectively to optimize the outcome for this large group of frail patients. This study examined nationwide variation in surgical methods used for hip fractures. METHODS In this cohort study 46,243 patients ≥65 years with a trochanteric hip fracture (THF) or a femoral neck fracture (FNF) registered in the Swedish Fracture Register (SFR) between 1 January 2016 and 31 December 2020 were included. Fractures were classified according to the AO Foundation/Orthopaedic Trauma Association (AO/OTA) fracture classification system. The choice of surgical methods was assessed for each fracture type to compare national variation. RESULTS 21,312 THFs and 24,072 FNFs (67% women) with a mean age of 83 years (SD 8) were surgically treated. In the treatment of two-fragment THFs (AO/OTA A1) departments ranged from using 90% short intramedullary nails to 98% sliding hip screws. Treating displaced FNFs (AO/OTA B3), the proportion of hemiarthroplasty ranged from 9 to 90%, and internal fixation between 0.6 to 21%, depending on the department. INTERPRETATION A mature national fracture register permits the monitoring of treatment provided and thus serves as an important aid in assessing compliance with guidelines. The large inter-departmental variation in the surgical management of hip fractures in Sweden appears unwarranted based on the current evidence, indicating a need for updated national guidelines. Further research will have to clarify the impact of this variation on mortality and re-operation rates.

Abstract
OBJECTIVE To evaluate the effect of warfarin on blood transfusion and postoperative complications in a low-energy hip fracture population compared with a non-anticoagulated comparison group. DESIGN Multicenter Retrospective Cohort. SETTING Three Urban Level I Academic Trauma Centers. PATIENTS Acute, low-energy, native hip fractures in patients 55 years of age or older on chronic warfarin anticoagulation, propensity score matched 1:2 to non-anticoagulated hip fracture patients meeting all other inclusion criteria. MAIN OUTCOME MEASUREMENTS Transfusion and postoperative complication rates. RESULTS Two hundred ten anticoagulated hip fracture patients were matched to 420 nonanticoagulated patients. A higher proportion of patients required blood transfusion in the warfarin cohort (52.4% vs. 43.3%, P < 0.001), attributable mostly to the subgroup of patients undergoing arthroplasty. Warfarin patients had higher incidence of overall 90-day complications (47% vs. 38%, P = 0.039) and readmissions (31.4% vs. 8.9%, P < 0.001). Day of surgery international normalized ratio (INR) did not influence transfusions or complications among warfarin patients. Warfarin patients undergoing surgery within 24 hours had no difference in transfusions and had fewer complications compared with those undergoing surgery after 24 hours. On multivariable logistic regression analysis, warfarin use and day of surgery INR were not predictors of transfusion or complications. CONCLUSIONS Patients on warfarin experienced longer time to surgery and higher incidence of overall transfusion and postoperative complications within 90 days of surgery. However, warfarin use and day of surgery INR was not independently associated with transfusions or complications. The reason for poorer outcomes in warfarin patients remains a topic of further investigation. LEVEL OF EVIDENCE Therapeutic Level III.

Epidemiology of more than 50,000 ankle fractures in the Swedish Fracture Register during a period of 10 years. J Orthop Surg Res 2023; 18:79. [PMID: 36721256 PMCID: PMC9887758 DOI: 10.1186/s13018-023-03558-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2022] [Accepted: 01/22/2023] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Despite being one of the most common types of fracture, there is a lack of epidemiological studies involving ankle fractures of all kinds. Since 2012, the Swedish Fracture Register (SFR) has prospectively collected data on surgically and non-surgically treated ankle fractures. The aim of this study is to describe the epidemiology of ankle fractures between 2012 and 2022. METHODS All ankle fractures registered in the SFR between 1 April 2012 and 31 March 2022 in patients aged 16 years or older were included. Information on age, sex, mechanism of injury, fracture classification according to AO/OTA and high- or low-energy trauma was retrieved from the SFR. RESULTS During the study period, 56,439 patients sustained 57,443 ankle fractures. Women (61%) were more commonly affected than men (39%). The mean age at the time of injury was 55 years. Men were found to be younger at the time of injury compared with women. Women were found to sustain open fractures more frequently, whereas the men more frequently sustained high-energy trauma. The most common mechanism of injury for all ankle fractures and for each AO/OTA44 fracture group separately was a simple fall. A seasonal variation in ankle fractures was found, where the number of ankle fractures peaked during the between November and March. CONCLUSIONS This study presents the epidemiology of all AO/OTA types of ankle fractures. We have demonstrated that most ankle fractures are caused by a simple fall and occur during wintertime. Women are more commonly affected than men and are older at the time of injury. These findings indicate that age-related skeletal fragility, as well as an increasing risk of simple falls in the elderly, may be risk factors for ankle fractures. This study will contribute to the planning of primary prevention for ankle fractures.

Abstract
Introduction A demographic survey of femoral pertrochanteric fractures provides several important information for the healthcare system of a country since this fracture is commonly seen in the elderly and has a poor postoperative functional prognosis that is a burden on society. The importance of accurately classifying pertrochanteric fractures as stable or unstable cannot be understated. However, the use of plain radiograph images alone is known to underestimate fracture severity with low inter- or intra-observer agreement. Computed tomography (CT) images offer information for a more accurate classification of pertrochanteric fractures. With this three-dimensional (3D) CT-based study using the revised Arbeitsgemeinschaft für Osteosynthesefragen/Orthopedic Trauma Association (AO/OTA) classification, the purpose of this study is to elucidate the epidemiological demography of patients with pertrochanteric fractures. Material and methods We retrospectively collected 808 patients from five hospitals, classified into two groups: stable (A1) or unstable (A2). Age, gender, fracture laterality, and surgery timing were identified as epidemiological variables. Patients with both preoperative plain radiographs and 3D CT scans were included in the study. The exclusion criteria were AO/OTA A3 type fractures, pathological fractures, previous ipsilateral surgery, 60 years old or younger, and conservatively treated patients. The primary outcome involved detailing the total number of fractures based on classification (A1 or A2) and variables. The secondary outcome involved a comparison between the A1 and A2 groups. Results The mean age of patients at the time of surgery was 85 years (range: 61-103 years). There were 637 female and 171 male patients. There were 463 left-sided fractures and 345 right-sided fractures. Of the 808 patients, 371 (45.9%) were classified to have A1 fractures, and 437 (54.1%) had A2 fractures. The age at surgery, gender, fracture laterality, and surgery timing between the A1 and A2 groups were compared. The mean and standard deviation of the age at surgery for patients in the A1 and A2 groups were 84.9±7.7 and 86.9±6.8, respectively. The number of patients for each age distribution of 61-69, 70-74, 75-79, 80-84, 85-89, 90-94, and 95 or older for the A1 and A2 groups was 18 and 7, 18 and 12, 43 and 44, 76 and 82, 107 and 132, 79 and 110, and 30 and 50, respectively, showing that the difference in categorial distribution was statistically significant (p=0.002). Overall, 278 females and 93 males were classified to have A1 fractures compared with 359 females and 78 males with A2 fractures (p=0.01). There were 166 right-sided and 205 left-sided stable A1 fractures and 179 right-sided and 258 left-sided A2 fractures (not significant (NS)). Among the total number of A1 and A2 surgeries by month, the most were in December with 77 surgeries (37 and 40, respectively), and the least was in June with 37 (18 and 19, respectively). The seasonal classification for A1 and A2 surgeries is as follows: spring with 172 (74 and 98, respectively), summer with 150 (70 and 80, respectively), autumn with 193 (90 and 103, respectively), and winter with 208 (97 and 111, respectively) (NS). Conclusion In this demographic study of 808 patients with pertrochanteric fractures classified by 3D CT images, 371 had A1 fractures and 437 had A2 fractures. A2 fractures were significantly more in females with an age peak of 85-89 years.

Bundled Payments for Hip Fracture Surgery Are Associated With Improved Access, Quality, and Health Care Utilization, but Higher Costs for Complex Cases: An Interrupted Time Series Analysis. J Orthop Trauma 2023; 37:19-26. [PMID: 35839456 DOI: 10.1097/bot.0000000000002459] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 07/12/2022] [Indexed: 02/02/2023]
Abstract
OBJECTIVES To study the impact of bundled payments for surgically managed hip fractures on care access, care quality, health care resource utilization, clinical impact, and acute care cost. DESIGN An observational retrospective cohort study using a quasi-experimental design comparing prebundled and postbundled payments through an interrupted time series analysis. SETTING A public acute care general hospital. PATIENTS Patients 60 years and older, with surgery for an isolated, unilateral, nonpathological hip fracture during 2014-first quarter of 2019 [diagnosis-related group codes: I03A, I03B, I08A, and I08B] and transferred to specific rehabilitation institutions were studied. INTERVENTION Bundled payments for funder-to-provider reimbursement. MAIN OUTCOMES MEASUREMENTS Care access, care quality, health care resource utilization, clinical impact, and cost. RESULTS Of 1477 patients, 811 were assigned to prebundled and 666 to postbundled payments. Although there was an improving trend of ward admission waiting times during postbundled payments [odds ratio (OR) = 1.14; 95% confidence interval (CI): 1.02-1.28], ward admission waiting times were longer when compared with prebundled payments (OR = 0.45; 95% CI: 0.23-0.85). Rates of 30-day all-cause readmissions were lower (OR = 0.08; 95% CI: 0.01-0.67), and trends of reducing inpatient rehabilitation and overall episode length of stay (OR = 1.26; 95% CI: 1.16-1.37 and OR = 1.17; 95% CI: 1.07-1.28, respectively) were demonstrated during postbundled payments. Acute care cost for complex cases were higher (OR = 0.49; 95% CI: 0.26-0.92) during bundled payments, compared with prebundled payments. CONCLUSIONS Bundled payments for surgically managed hip fractures were associated with benefits for several outcomes pertinent to clinical improvement initiatives. More work, especially concerning cost-effective surgical implants and better care cost computations, are critically needed to contain the growth of acute medical care cost for these patients.
