J Orthop 2024; 55:69-73. [PMID: 38681826 PMCID: PMC11047189 DOI: 10.1016/j.jor.2024.04.004] [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: 03/28/2024] [Accepted: 04/02/2024] [Indexed: 05/01/2024] Open
Abstract
Background Since 2014, the VA-LCP Condylar Plate 4.5/5.0, Depuy Synthes, has been the preferred implant for these injuries at our institution, however, speculations have been made whether it is more prone to failure compared to other implants. Thus, the aim of the study was to describe the cohort treated with the VA-LCP Condylar Plate 4.5/5.0, Depuy Synthes, at our department from 2014 to 2020, including the number of failures. Secondary, whether specific outcome measures were significantly overrepresented in the failure group. Methods Patients were identified through the hospital database, and demographic data was extracted from patient files. X-rays were evaluated for injury type, osteosynthesis characteristics, and whether the construct failed during follow-up. Thanks to the national patient record database a minimum of patients was lost to follow-up. Results After exclusion 159 patients (165 osteosyntheses, descriptive part) and 108 patients (112 osteosyntheses, subgroup analysis) were eligible for inclusion. The VA-LCP Condylar Plate 4.5/5.0, Depuy Synthes, was used for most AO-type fractures and inserted as both neutralization, buttress, and bridging plates. Overall failure was seen in 8 % of osteosyntheses. Significantly more failures were seen in patients with increased Body Mass Index (BMI) (24 vs. 32, p = 0,046) and those treated for a periprosthetic fractures (41 % vs. 89 %, p = 0,005). We did not see an association between failure and plate length, bridge span, screw density or the degree of medial support. Conclusion The VA-LCP Condylar Plate 4.5/5.0, Depuy Synthes is a versatile plate with failure rates comparable to previously reported studies. This study confirmed that elevated BMI may be a risk factor for failure, while other previously reported risk factors were not associated with failure in this study.

Abstract
Delayed union and non-union of fractures continue to be a major problem in trauma and orthopedic surgery. These cases are challenging for the surgeon. In addition, these patients suffer from multiple surgeries, pain and disability. Furthermore, these cases are a major burden on healthcare systems. The scientific community widely agrees that the stability of fixation plays a crucial role in determining the outcome of osteosynthesis. The extent of stabilization affects factors like fracture gap strain and fluid flow, which, in turn, influence the regenerative processes positively or negatively. Nonetheless, a growing body of literature suggests that during the fracture healing process, there exists a critical time frame where intervention can stimulate the bone's return to its original form and function. This article provides a summary of existing evidence in the literature regarding the impact of different levels of fixation stability on the strain experienced by newly forming tissues. We will also discuss the timing and nature of this "window of opportunity" and explore how current knowledge is driving the development of new technologies with design enhancements rooted in mechanobiological principles.

[PMID: 38508908 DOI: 10.1016/j.cjtee.2024.03.001] [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: 09/05/2023] [Revised: 01/09/2024] [Accepted: 02/01/2024] [Indexed: 03/22/2024] Open
Abstract
PURPOSE To comprehensively analyze the geographic and temporal trends of foot fracture, understand its health burden by age, sex, and sociodemographic index (SDI), and explore its leading causes from 1990 to 2019. METHODS The datasets in the present study were generated from the Global Burden of Diseases Study 2019, which included foot fracture data from 1990 to 2019. We extracted estimates along with the 95% uncertainty interval (UI) for the incidence and years lived with disability (YLDs) of foot fracture by location, age, gender, and cause. The epidemiology and burden of foot fracture at the global, regional, and national level was exhibited. Next, we presented the age and sex patterns of foot fracture. The leading cause of foot fracture was another focus of this study from the viewpoint of age, sex, and location. Then, Pearson's correlations between age-standardized rate (ASR), SDI, and estimated annual percentage change were calculated. RESULTS The age-standardized incidence rate was 138.68 (95% UI: 104.88 - 182.53) per 100,000 persons for both sexes, 174.24 (95% UI: 134.35 - 222.49) per 100,000 persons for males, and 102.19 (95% UI: 73.28 - 138.00) per 100,000 persons for females in 2019. The age-standardized YLDs rate was 5.91 (95% UI: 3.58 - 9.25) per 100,000 persons for both genders, 7.35 (95% UI: 4.45 - 11.50) per 100,000 persons for males, and 4.51 (95% UI: 2.75 - 7.03) per 100,000 persons for females in 2019. The global incidence and YLDs of foot fracture increased in number and decreased in ASR from 1990 to 2019. The global geographical distribution of foot fracture is uneven. The incidence rate for males peaked at the age group of 20 - 24 years, while that for females increased with advancing age. The incidence rate of older people was rising, as younger age incidence rate declined from 1990 to 2019. Falls, exposure to mechanical forces, and road traffic injuries were the 3 leading causes of foot fracture. Correlations were observed between ASR, estimated annual percentage change, and SDI. CONCLUSIONS The burden of foot fracture remains high globally, and it poses an enormous public health challenge, with population ageing. It is necessary to allocate more resources to the high-risk populations. Targeted realistic intervention policies and strategies are warranted.

Abstract
INTRODUCTION Understanding the epidemiology and incidence of fractures can help inform policymakers and clinicians about the needs of the population and highlight trends over time, allowing for tailoring of healthcare delivery to the population. This study reports on the lower limb fractures treated at a major trauma centre over a seven-year period. METHODS We collected data on fracture locations, age, gender, BMI, hospital admission length, and treatment options of all lower limb fractures treated at a level I trauma centre from January 2015 to December 2021. We included data on the femur, tibia, and fibula, which were each split up into distinct regions. Fractures were subdivided by location and graphed, separated by gender, over age group. Finally, each location area's frequency was graphed over the entire study period. RESULTS A total of 8,511 patients sustained 8,613 fractures, given an overall incidence of 215.9 fractures per 100,000 patients per year. The mean age was 62.3 years, and 56.3% of patients were female. Fractures of the peri trochanteric region of the femur had the highest mean average age (79.9 years), which was closely followed by fractures of the head and neck of the femur (78.2 years). Fractures of the head and neck of the femur and the peri trochanteric region of the femur also had the highest proportion of females suffering from these fractures (67 and 66% female, respectively). Femur shaft fractures had the lowest average age (36.5 years) and the lowest proportion of female patients (29%). On graphing by location, separated by gender, over age group, overall fractures showed a bi-peak distribution of younger males and older, post-menopausal females having their respective peaks. Three further distinct distributions were observed in individual location fractures. CONCLUSION Identifying the relative incidence and demographic associations with lower limb fractures helps highlight a changing population's needs. There is an absence of such study in literature in the United Kingdom (UK) since 2006. Our study's insights and results aid clinicians and policymakers in the creation of guidelines and the distribution of resources based on the most recent information and elucidate changing healthcare service needs for the population.

Abstract
Objective The perioperative management of patients on antiplatelet drugs is a rising challenge in orthopedic trauma because antiplatelet drugs are frequently encountered and carry an increased risk of hemorrhagic consequences. The study objective was to examine the effect of aspirin on bleeding outcomes for patients with lower extremity fractures. Methods This retrospective study included patients requiring surgical fixation of traumatic hip, femur, and tibia fractures from January 1, 2018, to March 1, 2020. Patients were excluded if they had a significant head injury, were on chronic anticoagulant therapy, or they did not receive venous thromboembolism chemoprophylaxis. Comparisons between aspirin users (patients on aspirin therapy preinjury) and non-aspirin users were examined using χ2 tests, Cochran-Mantel-Haenszel tests, and multivariate logistic regression. The primary outcome was an overt, actionable bleed (eg, blood transfusion for surgical site hemorrhage) within 24 hours postoperative. Results There were 864 patients with lower extremity long bone fractures and 24% were aspirin users. The incidence of postoperative bleeding was 8.8% and significantly differed for patients taking aspirin versus not (13.6% vs 7.3%, p=0.01). However, biological sex at birth (M/F) was a significant effect modifier (interaction p=0.04). Among women, there were significantly more postoperative bleeds for aspirin users (17.8% aspirin vs 7.4% no aspirin, adjusted OR (AOR): 2.48 (1.28-4.81), p=0.01). Among men, there were similar postoperative bleeding events by aspirin use (5.6% aspirin vs 7.2% no aspirin, AOR: 0.50 (0.14-1.82), p=0.30). Postoperative hemoglobin values <8 g/dL were more frequent among female aspirin users (21.5% aspirin vs 12.5% no aspirin, p=0.01), but this association was not observed in men (p=0.43). Conclusion Women taking aspirin who suffer lower extremity fractures have greater than twofold greater odds of a postoperative bleeding event. These findings suggest adequate perioperative planning to ensure blood availability, and increased awareness to monitor closely for hemorrhage in the 24-hour postoperative window for women taking aspirin preinjury. Level of evidence IV.

Abstract
BACKGROUND The incidence of nonhip femoral fractures is gradually increasing, but few studies have explored the risk factors for in-hospital death in patients with nonhip femoral fractures in the ICU or developed mortality prediction models. Therefore, we chose to study this specific patient group, hoping to help clinicians improve the prognosis of patients. METHODS This is a retrospective study based on the data from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. Least absolute shrinkage and selection operator (LASSO) regression was used to screen risk factors. The receiver operating characteristic (ROC) curve was drawn, and the areas under the curve (AUC), net reclassification index (NRI) and integrated discrimination improvement (IDI) were calculated to evaluate the discrimination of the model. The consistency between the actual probability and the predicted probability was assessed by the calibration curve and Hosmer-Lemeshow goodness of fit test (HL test). Decision curve analysis (DCA) was performed, and the nomogram was compared with the scoring system commonly used in clinical practice to evaluate the clinical net benefit. RESULTS The LASSO regression analysis showed that heart rate, temperature, red blood cell distribution width, blood urea nitrogen, Glasgow Coma Scale (GCS), Simplified Acute Physiology Score II (SAPSII), Charlson comorbidity index and cerebrovascular disease were independent risk factors for in-hospital death in patients with nonhip femoral fractures. The AUC, IDI and NRI of our model in the training set and validation set were better than those of the GCS and SAPSII scoring systems. The calibration curve and HL test results showed that our model prediction results were in good agreement with the actual results (P = 0.833 for the HL test of the training set and P = 0.767 for the HL test of the validation set). DCA showed that our model had a better clinical net benefit than the GCS and SAPSII scoring systems. CONCLUSION In this study, the independent risk factors for in-hospital death in patients with nonhip femoral fractures were determined, and a prediction model was constructed. The results of this study may help to improve the clinical prognosis of patients with nonhip femoral fractures.

Abstract
The aim of this study is to develop a digital monitoring system to track weight and evaluate its impact on postoperative outcomes after lower extremity surgeries (LES). This parallel randomized controlled trial enrolled 266 patients who underwent LES (fracture or joint replacement) at our medical center between March 11, 2022, and January 10, 2023. Patients were randomly assigned to the intervention and control groups in a 1:1 ratio. The intervention group (n=116) used a cane and shoes equipped with a weight-bearing system after lower limb surgery, while the control group (n=116) used a simple cane and shoes without a weight-bearing system. The primary outcomes included callus formation, duration of union, and success rate of union in the two groups. The intervention group had a significantly higher rate of complete surgical success than the control group (93.9% vs. 79.3%, p=0.001). The intervention group also had a significantly lower risk of non-union than the control group (OR: 2.33, 95% CI: 1.14, 3.48, p=0.001). The mean duration of surgery until the time of union and the meantime of callus formation was significantly lower in the intervention group (p=0.01). The use of a digital monitoring system for weighing in LES significantly increased the success rate and reduced post-operative complications. Therefore, incorporating this system can enhance the rehabilitation process and prevent revision surgeries in patients with LES.

Abstract
The benefits of isometric strengthening exercises (ISEs) are compromised when patient teaching on ISEs is delayed and/or ineffectively delivered due to healthcare resources constraint, especially when health resources are stretched, as occurred during the COVID-19 pandemic. This study aims to examine the effect of a video-assisted ISE program on pain and muscle strength of patients following surgical stabilization of lower limb fracture. A quasi-experimental study with repeated measures was employed. Primary study outcomes were assessed using the Brief Pain Inventory and Manual Muscle Test. Effects over time were analyzed using generalized estimating equations. In comparison with usual care group (n = 32), the intervention group (n = 33) showed better pain reduction over time (p < .001, effect size [ES] = 0.39-1.77) and muscle strength preservation (p < .05; ES = 0.8-0.9). Patient acceptance of the intervention was favorable. Integration of video clips into patient teaching on ISEs is potentially beneficial in managing pain and muscle strength; it can be easily deployed to aid early ISE initiation.

Abstract
OBJECTIVES This work aimed at answering the following research questions: (1) What is the incidence of femoral shaft fractures in the geriatric population in the U.S.? (2) What is the rate of mortality, mechanical complications, nonunion and infection, and what are the associated risk factors? STUDY DESIGN AND SETTING In this cross-sectional study, femoral shaft fractures occurred between January 1, 2009, and December 31, 2019, were identified from Medicare records. Rates of mortality, nonunion, infection, and mechanical complications were calculated with the Kaplan-Meier method with Fine and Gray sub-distribution adaptation. Semiparametric Cox regression was applied with twenty-three covariates to determine risk factors. RESULTS Between 2009 through 2019 the incidence of femoral shaft fractures decreased by 12.07% to 40.8/100,000 inhabitants (p = 0.549). The 5-year mortality risk was 58.5%. Male sex, age over 75 years, chronic obstructive pulmonary disease, cerebrovascular disease, chronic kidney disease, congestive heart failure, diabetes mellitus, osteoporosis, tobacco dependence, and lower median household income were significant risk factors. The infection rate was 2.22% [95%CI: 1.90-2.58] and the union failure rate 2.52% [95%CI: 2.17-2.92] after 24 months. CONCLUSION An early assessment of individual patient risk factors may be beneficial in the care and treatment of patients with these fractures.

Zeelenberg ML, Den Hartog D, Panneman MJM, Polinder S, Verhofstad MHJ, Van Lieshout EMM. Trends in incidence, health care consumption, and costs for proximal femoral fractures in the Netherlands between 2000 and 2019: a nationwide study. Osteoporos Int 2023:10.1007/s00198-023-06774-y. [PMID: 37119329 PMCID: PMC10382328 DOI: 10.1007/s00198-023-06774-y] [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: 03/17/2023] [Accepted: 04/21/2023] [Indexed: 05/01/2023]
Abstract
This study evaluated the incidence rates and societal burden of hip fractures in The Netherlands. Although incidence in the elderly population is decreasing and hospital stay is at an all-time low, the burden of medical costs and crude numbers of proximal femoral fractures are still rising in our aging population. PURPOSE The aim of this nationwide study was to provide an overview of the incidence rate and economic burden of acute femoral neck and trochanteric fractures in The Netherlands. METHODS Data of patients who sustained acute proximal femoral fractures in the period January 1, 2000, to December 31, 2019, were extracted from the National Medical Registration of the Dutch Hospital Database. The incidence rate, hospital length of stay (HLOS), health care and lost productivity costs, and years lived with disability (YLD) were calculated for age- and sex-specific groups. RESULTS A total of 357,073 patients were included. The overall incidence rate increased by 22% over the 20-year study period from 16.4 to 27.1/100,000 person-years (py). The age-specific incidence rate in elderly > 65 years decreased by 16% (from 649.1 to 547.6/100,000 py). The incidence rate in men aged > 90 has surpassed the incidence rate in women. HLOS decreased in all age groups, hip fracture subtypes, and sexes from a mean of 18.5 to 7.2 days. The mean health care costs, over the 2015-2019 period, were lower for men (€17,723) than for women (€23,351) and increased with age to €26,639 in women aged > 80. Annual cumulative costs reached €425M, of which 73% was spent on women. CONCLUSION The total incidence of hip fractures in The Netherlands has increased by 22%. Although incidence in the elderly population is decreasing and HLOS is at an all-time low, the burden of medical costs and crude numbers of proximal femoral fractures are still rising in our aging population.

Free flaps for lower limb soft tissue reconstruction - A systematic review of complications in 'Silver Trauma' patients. Injury 2023:S0020-1383(23)00294-2. [PMID: 37032183 DOI: 10.1016/j.injury.2023.03.038] [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: 01/26/2023] [Revised: 03/20/2023] [Accepted: 03/28/2023] [Indexed: 04/11/2023]
Abstract
BACKGROUND There are 12.5 million people aged 65 years and older living in the UK. The annual incidence of open fracture is 30.7 per 10,000 person-years. In females, 42.9% of all open fractures occur in patients ≥ 65 years. METHODS AND MATERIALS Preferred Reporting for Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, and the study is registered with PROSPERO (CRD42020209149). The aim was to compare the complication profiles of free fasciocutaneous flaps and free muscular flaps in patients aged over 60 years undergoing lower limb soft tissue reconstruction following an open lower limb fracture. The search strategy based on strict inclusion criteria included PubMed, Embase and Google Scholar. RESULTS 15 papers were identified, including 46 patients with 10 free fasciocutaneous flaps and 41 free muscle flaps. There were 3 complications in the fasciocutaneous group (30%) and 9 complications in the muscle group (22%). There was a total of 1 secondary procedure in the fasciocutaneous group and 4 in the muscle group. DISCUSSION There is insufficient data to provide statistical comparison between free fasciocutaneous versus free muscle flaps for lower limb reconstruction performed in those aged over 60 years. This systematic review highlights evidence for the successful use of free tissue transfer in the older population following an open fracture injury and requiring lower limb reconstruction. There is no evidence to suggest the superiority of one tissue type over the other, with the inference that well vascularised tissue is the most significant factor impacting outcome.

Mortality and morbidity following operative management of tibial shaft fractures in octogenarians. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2023; 33:299-304. [PMID: 35031851 DOI: 10.1007/s00590-021-03180-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Accepted: 11/27/2021] [Indexed: 10/19/2022]
Abstract
PURPOSE As the geriatric population continues to grow, the incidence of tibial shaft fractures in octogenarians is projected to increase. There is significant variation in the functional and physiologic status within the geriatric population. The purpose of this study is to compare the complications following operative treatment of tibial shaft fractures for patients who are 65- to79-year-old compared to patients who are 80- to 89-year-old. METHODS Data were collected through the National Surgical Quality Improvement Program database for the years 2007-2018. All isolated tibial shaft fractures that were treated with open reduction internal fixation (ORIF) or intramedullary nail (IMN) were identified. Patients were divided into a 65- to 79-year-old group and an 80-to 89-year-old group. Primary and secondary outcomes were studied and included 30-day mortality. Univariate and multivariate analyses were performed with a significance set at p < 0.05. RESULTS In total, 434 patients with tibial shaft fractures were included in the study. Of these, 333 were 65- to 79-year-old and 101 were 80- to 89-year-old (Table 1). On multivariate analysis, there was no significant difference in complication rates between the two cohorts. CONCLUSION After controlling for demographics and comorbidities, age was not independently associated with 30-day mortality or any other peri-operative complications between patients aged 80 to 89 and patients aged 65 to 79 following operative management of tibial shaft fractures. In appropriately selected octogenarian patients, operative management of tibial shaft fractures represents a relatively safe treatment modality that may promote early rehabilitation.

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.

Extent of bone marrow edema on dual-energy CT aids in differentiation of acute from post-acute fractures of lower legs. Eur Radiol 2023; 33:4094-4102. [PMID: 36600125 DOI: 10.1007/s00330-022-09373-3] [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: 10/19/2022] [Revised: 10/19/2022] [Accepted: 12/08/2022] [Indexed: 01/06/2023]
Abstract
OBJECTIVES Bone marrow edema (BME) from dual-energy CT is useful to direct attention to radiographically occult fractures. The aim was to characterize utility of BME of lower extremity (LE) fractures with the hypothesis that stabilized and post-acute fractures exhibit decreased extent and frequency of BME than non-stabilized and acute fractures, respectively. METHODS An IRB-approved retrospective review of known LE fractures. A total of 141 cases met inclusion criteria, including 82 fractures without splint/cast stabilization, and 59 cases with stabilization. Two readers independently recorded BME, and its multiplicity and area (mm2). A separate reader assessed fracture location, comminution, and chronicity. Wilcoxon rank sum test, multiple regression, intraclass correlation (ICC), kappa statistics, and chi-square tests were used. RESULTS BME was significantly larger in non-stabilized (859.3 mm2 (420.6-1451.8)) than stabilized fractures (493.5 mm2 (288.8-883.2)), p = .011). Comminuted (p = 0.006), non-stabilized (p = 0.0004), and acute fractures (p = 0.036) were all associated with larger BME area. BME presence had excellent results for both stabilized (Cohen's Kappa = 0.81) and non-stabilized fractures (Cohen's Kappa = 0.84). ICC for BME area showed excellent correlation for both stabilized (ICC = 0.78) and non-stabilized groups (ICC = 0.86). BME multiplicity showed excellent agreement for stabilized (ICC = 0.81) and good agreement for non-stabilized (ICC = 0.67) fractures. Lastly, stabilized cases showed increased multiplicity of BME compared to non-stabilized fractures (p < 0.001). CONCLUSIONS BME evaluation can assist in differentiation of acute versus post-acute fractures. Extent of BME is reduced with splint/cast stabilization, which may limit its accuracy in detection of lower extremity fractures. KEY POINTS • Evaluation of bone marrow edema on dual-energy CT aids in differentiation of acute versus post-acute fracture. • Bone marrow edema evaluation is limited in the setting of post-acute or stabilized fractures. • There is decreased frequency and extent of bone marrow edema in post-acute, non-comminuted, and stabilized 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.

Abstract
INTRODUCTION This is a retrospective study evaluating the use of a new six-item modified frailty index (MF-6) to predict short-term outcomes of patients receiving surgery for lower extremity fractures. METHODS Patients older than 65 years undergoing open reduction and internal fixation for lower extremity, pelvic, and acetabulum fractures were identified from the American College of Surgeons National Surgical Quality Improvement Program. The MF-6 was calculated by assigning one point for each of six common conditions. Multivariable analysis was used to compare patients with an MF-6 of <3 and ≥3. Outcome measures included complications, mortality, readmission, revision surgery, and length of stay. An area under the curve receiver operator analysis was conducted to compare the MF-6 with MF-5, an existing five-item frailty index. RESULTS Nine thousand four hundred sixty-three patients were included. Patients with an MF-6 of ≥3 were at markedly higher risk of discharge destination other than home (Exp[B] = 2.09), mortality (Exp[B] = 2.48), major adverse events (Exp[B] = 2.16), and readmission (Exp[B] = 1.82). Receiver-operating curve analysis demonstrated an area under the curve of 0.65 for mortality, 0.62 for major adverse events, and 0.62 for discharge destination other than home, all of which outperformed the MF-5. DISCUSSION The MF-6 was correlated with a 30-day postoperative incidence of infectious complications, readmission, and discharge destination. MF-6 scores can be used to risk-stratify patient populations as shifts to value-based care continue to develop.

Incidence and nonunion rates of tibial fractures in adults with osteogenesis imperfecta: a retrospective cohort study of 402 patients with 42 fractures at an expert clinic. BMC Musculoskelet Disord 2022; 23:1077.

Abstract
BACKGROUND Tibial fractures are the most common fractures seen in adults and lead to the most nonunions. Osteogenesis imperfecta (OI) is characterized by increased bone fragility and higher risk of fractures. No studies have been published on the incidence of tibial fractures and nonunions in adults with OI. This study aims to summarize the incidence of tibial fractures and nonunions in this population. METHODS A retrospective, descriptive study. All medical charts of adult patients in the OI database of our OI expert clinic were analyzed for tibial fractures between 2008 and 2020. Tibial fracture incidence, nonunion rate, treatment modality and potential risk factors were determined. RESULTS The database consisted of 402 patients, 34 of whom had suffered one or more tibial fractures, resulting in 42 fractures. The incidence of tibial fractures in adults with OI is 870 per 100,000 person-years. Two out of 42 fractures led to nonunion (5%). It was not possible to adjust for risk factors or type of treatment. CONCLUSION There is a higher incidence of tibial fractures in patients with OI, but a nonunion rate comparable to the general population. With only two nonunions it is not possible to draw conclusions on the influence of risk factors or treatment of tibial fractures on OI.

Osteoporos Int 2022; 33:2327-2335. [PMID: 35916908 PMCID: PMC9568487 DOI: 10.1007/s00198-022-06481-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2022] [Accepted: 06/20/2022] [Indexed: 10/28/2022]
Abstract
UNLABELLED Between 1998 and 2018, the number of hospitalizations for major osteoporotic fractures increased. After standardization for age, these numerical increases translated into a reduced incidence of hospitalizations for hip fractures and an increased incidence of hospitalizations for spine, proximal humerus, and distal radius fractures in both sexes. INTRODUCTION The longterm epidemiological trends of hospitalizations for major osteoporotic fractures (MOF) between 1998 and 2018 in Switzerland are unknown. METHODS The absolute number of acute hospitalizations for MOF (hip fractures and fractures of the spine, proximal humerus, and distal radius) and related length of acute hospital stay were extracted from the medical database of the Swiss Federal Office of Statistics. Age-standardized incidence rates were calculated using 1998 as the reference year. RESULTS Hospitalizations for MOF increased from 4483 to 7542 (+ 68.2%) in men and from 13,242 to 19,362 (+ 46.2%) in women. The age-standardized incidence of hospitalizations for MOF increased by 5.7% in men (p = 0.002) and by 5.1% in women (p = 0.018). The age-standardized incidence of hip fractures decreased by 15.3% in men (p < 0.001) and by 21.5% in women (p < 0.001). In parallel, the age-standardized incidence of MOF other than hip fractures increased by 31.8% in men (p < 0.001) and by 40.1% in women (p < 0.001). The mean length of acute hospital stays for MOF decreased from 16.3 to 8.5 days in men and from 16.9 to 8.1 days in women. CONCLUSION Between 1998 and 2018, the number of hospitalizations for MOF increased significantly by a larger extent than expected based on the ageing of the Swiss population alone. This increase was solely driven by an increased incidence of MOF other than hip fractures as incident hip fractures decreased over time in both sexes, more so in women than in men.

Abstract
BACKGROUND Fractures of the distal femur (the far end of the thigh bone just above the knee) are a considerable cause of morbidity. Various different surgical and non-surgical treatments have been used in the management of these injuries but the best treatment remains unknown. OBJECTIVES To evaluate the benefits and harms of interventions for treating fractures of the distal femur in adults. SEARCH METHODS We used standard, extensive Cochrane search methods. The latest search date was October 2021. SELECTION CRITERIA We included randomised and quasi-randomised controlled trials in adults comparing interventions for treating fractures of the distal femur. Interventions included surgical implants (retrograde intramedullary nail (RIMN), fixed-angle devices, non-locking plate fixation, locking plate, internal fixation, distal femoral replacement, mono-axial plates, poly-axial plates and condylar buttress plates) and non-surgical management. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. Our critical outcomes were validated patient-reported outcome measures (PROMs), direct adverse events, participant-reported quality of life (QoL) and pain scores. Our other important outcomes were adverse events indirectly related to intervention, symptomatic non-union, malunion and resource use. We used GRADE to assess certainty of evidence for each outcome. MAIN RESULTS We included 14 studies with 753 participants: 13 studies compared different surgical interventions, and one study compared surgical with non-surgical management. Here, we report the effects for RIMN compared with locking plates. Three studies (221 participants) reported this comparison; it included the largest study population and these are the two most commonly used devices in contemporary orthopaedic trauma practice. Studies used three different tools to assess PROMs. We found very-low certainty evidence for lower Disability Rating Index scores after RIMN at short-term follow-up favouring RIMN (mean difference (MD) -21.90, 95% confidence interval (CI) -38.16 to -5.64; 1 study, 12 participants) and low-certainty evidence of little or no difference at long-term follow-up (standardised mean difference (SMD) -0.22, 95% CI -0.50 to 0.06; 2 studies, 198 participants). Re-expressing the SMD of the long-term follow-up data to Knee Society Score (KSS) used by one study found no clinical benefit of RIMN, based on a minimal clinically important difference of 9 points (MD 2.47, 95% CI -6.18 to 0.74). The effect on QoL was very uncertain at four months (MD 0.01, 95% CI -0.42 to 0.44; 1 study, 14 participants) and one year (MD 0.10, 95% CI -0.01 to 0.21; 1 study, 156 participants); this evidence was very low certainty. For direct adverse events, studies reported reoperation, loss of fixation, superficial and deep infection, haematoma formation and implant loosening. Effects for all events were imprecise with the possibility of benefit or harm for both treatments. We considered reoperation the most clinically relevant. There was very low-certainty evidence of little or no difference in reoperation between the two implants (risk ratio (RR) 1.48, 95% CI 0.55 to 4.00; 1 study, 104 participants). No studies reported pain. For other important outcomes, we noted that people treated with RIMN may be more likely to have varus/valgus deformity (RR 2.18, 95% CI 1.09 to 4.37; 1 study, 33 participants; low-certainty evidence). However, we found no evidence of any important differences between treatments in terms of bony union, indirect adverse events, or resource use. Other comparisons of surgical interventions included in the review were: RIMN versus single fixed-angle device (3 studies, 175 participants); RIMN versus non-locking plate fixation (1 study, 18 participants); locking plate versus single fixed-angle device (2 studies, 130 participants); internal fixation versus distal femoral replacement (1 study, 23 participants); mono-axial plates versus poly-axial plates (2 studies, 67 participants); mono-axial plate versus condylar buttress plate (1 study, 78 participants). The certainty of the evidence for outcomes in these comparisons was low to very low, and most effect estimates were imprecise. AUTHORS' CONCLUSIONS This review highlights the major limitations of the available evidence concerning current treatment interventions for fractures of the distal femur. The currently available evidence is incomplete and insufficient to inform clinical practice. Priority should be given to randomised controlled trials comparing contemporary treatments for people with fractures of the distal femur. At a minimum, these should report validated patient-reported functional and quality-of-life outcomes at one and two years, with an agreed core outcome set. All trials should be reported in full using the CONSORT guidelines.

Abstract
Background Although the relatively high incidence of coronal fractures in the supracondylar–intercondylar fractures is well established, little is currently known about the morphology of those fractures. Herein, we characterized the coronal fractures in AO/OTA type 33-C3 and assessed their differences with Busch–Hoffa fractures (33-B3).
Methods We retrospectively collected 61 cases of AO/OTA type 33-B or C fractures with coronal plane fragments and generated three-dimensional fracture maps of those with coronal fractures based on CT imaging and measured angle α (the angle between the coronal fracture and the posterior condyle axis in the axis plane) and angle β (the angle between the coronal fracture and the posterior femoral cortex in the sagittal plane). Results Thirty-three cases (32%) of AO/OTA type 33-C fractures contained coronal fragments. Most of them were type 33-C3 fractures. Angles α and β for type 33-C3 were significantly smaller than for type B3 at the lateral condyle, while the angles at the medial condyle were not significantly different. The fracture maps showed that the coronal fractures and the articular comminution area were more anterior in type 33-C3. Conclusions The incidence of coronal fractures was 32% and 67% in AO/OTA types 33-C and 33-C3, respectively. Our findings suggest that coronal fractures differed between both types, emphasizing the potential need for different treatment approaches.

Abstract
Previous studies have shown that preoperative factors predict the postoperative Barthel Index score in patients with trochanteric fractures, while there is less evidence on the effects of perioperative factors on the prediction. This study aimed to assess the effects of preoperative and perioperative factors on the early postoperative Barthel Index score in patients with trochanteric fractures. Consecutive 288 patients aged ≥60 years with trochanteric fractures who could independently walk before injury were included. Patients were grouped according to the Barthel Index score measured after 2 weeks of surgery; the cut-off value was 20 points. Two logistic regression models were created to assess the effects of preoperative (model 1: dementia, walking ability before injury, and nutrition status) and perioperative (model 2: independent variables in model 1, reduction quality, and basic mobility function) factors on the Barthel Index score. Sensitivity and specificity were used to assess the predicative accuracy of the models. Poor preoperative (model 1: χ2 = 34.626, P < 0.01) and perioperative (model 2: χ2 = 43.956, P < 0.01) characteristics were significantly related to lower Barthel Index score. Sensitivity and specificity were similar between the models (model 1: 83.3% and 38.9% and model 2: 82.2% and 42.6%, respectively). Both preoperative and perioperative factors were significantly related to the early postoperative Barthel Index score after trochanteric fracture. However, only minimal increase in predictive accuracy was observed when perioperative predictors were analyzed along with preoperative factors. Both baseline characteristics and basic postoperative mobility should be considered when treating patients with trochanteric fractures.
