Abstract
INTRODUCTION The purpose of this study was to validate the humeral fracture diagnoses for adults in the Danish National Patient Registry (DNPR). METHODS This was a population-based validity study, including adult patients (≥ 18 years) with a humeral fracture referred to the emergency department of hospitals in three Danish regions from March 2017 to February 2020. Administrative data were retrieved on 12,912 patients from the databases of the involved hospitals. These databases hold information on discharge and admission diagnoses, which is based on the International Classification of Diseases, tent version. Data of 100 cases were randomly sampled from each of the specific humeral fracture diagnoses (S42.2-S42.9). The positive predictive value (PPV) was estimated for each diagnosis to study the recorded accuracy. Radiographic images from the emergency departments were reviewed and assessed as the gold standard. The PPVs with 95% confidence intervals (CI) were estimated according to the Wilson method. RESULTS In total, 661 patients were sampled between all available diagnosis codes. Overall, the PPV for humeral fracture was 89.3% (95% CI: 86.6-91.4%). PPVs for the subdivision codes were 91.0% (95% CI: 84.0-95.0%) for proximal humeral fractures, 89.0% (95% CI: 81.0-94.0%) for humeral diaphyseal fractures and 78.0% (95% CI: 68.9-84.9%) for distal humeral fractures. CONCLUSION The validity of the humeral fracture diagnosis and the classifications of proximal and diaphyseal fractures in the DNPR is high, and the DNPR may therefore be used in registry research. Diagnosis of distal humeral fractures has a lower validity and should be used with caution. FUNDING none. TRIAL REGISTRATION not relevant.

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 The choice between invasive and non-invasive treatment of diaphyseal forearm fractures in children can be difficult. We investigated the trends in choice of treatment of pediatric diaphyseal forearm fractures over a 20-year period. Patients and methods: This is a population-based register study with data from 1997 to 2016 retrieved from the Danish National Patient Registry. The primary outcome was choice of primary treatment within 1 week divided into non-invasive treatment (casting only or closed reduction including casting) and invasive (Kirshner wires, intramedullary nailing [IMN], and open reduction internal fixation [ORIF]). The secondary outcomes were further sub-analyses on invasive treatment and age groups. RESULTS 36,244 diaphyseal forearm fractures were investigated, yielding a mean incidence of 172 per 105/year. The proportion of fractures treated invasively increased from 1997 to 2016, from 4% to 23%. The use of Kirschner wires increased from 1% to 9%, IMN increased from 1% to 14%, and ORIF decreased from 2% to 1%. The changes were evident in all age groups but smaller in the 0-3-year age group. CONCLUSION We found an increase in invasive treatment of pediatric diaphyseal forearm fractures over the investigated period. A change in invasive methods was also found, as the rate of IMN increased over the investigated period and became the predominant surgical treatment choice.

Abstract
INTRODUCTION It is still debated whether to use cannulated cancellous screw (CCS) or sliding hip screw (SHS) implants for femoral neck fracture (FNF) patients but there are no studies large enough to evaluate on smaller differences. The aim were to compare the reoperation and mortality rates of a large cohort of FNF patients above 60 years of age with internal fixation using CCS and SHS implants, with stratification by fracture classification. METHODS This register study employed prospectively collected data from 2014 to 2018 from the Danish Fracture Database, including 2-year follow-up and data on age, sex, surgery, comorbidity and fracture classification. Reoperation data was retrieved from the Danish National Patient Register. The primary outcome was major reoperation, defined as re-osteosynthesis, conversion to arthroplasty, non-union surgery, Girdlestone procedure or deep infection 1-year post-surgery. Relative risk (RR) for the CCS group compared with the SHS group was estimated using Cox proportional hazards modelling, adjusted for age, sex and comorbidity (including 95% confidence intervals). RESULTS A total of 2,598 FNFs were included, 1,731 with CCS (67%) and 867 with SHS (33%). The overall 1-year major reoperation rate was 15% with CCS and 13% with SHS, yielding an adjusted RR of 1.10 (0.88; 1.37) for CCS compared to SHS. The adjusted RR was 1.15 (0.77; 1.69) for undisplaced FNF, 1.09 (0.68; 1.75) for displaced FNF and 1.35 (0.94; 1.94) for transcervical FNF, which increased to 1.42 (1.01; 2.00) after 2 years. The minor reoperation rate was higher for CCS (3%) than SHS (1%), yielding an adjusted RR of 2.28 (1.14; 4.51). The adjusted RR for CCS compared to SHS was 0.83 (0.62; 1.12) for 30-day mortality and 0.96 (0.82; 1.14) for 1-year mortality. CONCLUSIONS We found no difference between CCS and SHS in major reoperation rates; however, for transcervical FNF, CCS was associated with higher reoperation rates. Furthermore, CCS was associated with a higher risk of minor reoperation than SHS. There were no differences in mortality rates.

Abstract
INTRODUCTION Information on data validity is essential for understanding the precision of studies based on data from the Danish National Patient Registry (DNPR). Thus, the aim of this study was to validate the quality of ankle fracture data in the DNPR. METHODS We identified all patients from four hospitals with a surgically treated ankle fracture between 1 January 2018 and 31 December 2018. The positive predictive value (PPV) was estimated for a random sample of 10% of patients with both a relevant ankle fracture diagnosis code and a relevant procedure code, as well as for patients with only a relevant ankle fracture diagnosis code or a relevant ankle fracture procedure code. We collected data from medical records and X-rays. Two consultants independently validated the ankle fracture diagnosis and procedure codes reported to the DNPR. RESULTS Among the four centres, 651 patients were identified with both an ankle fracture diagnosis and a procedure code. Among these, data from 65 (10%) patients were extracted for validation. For these patients, the PPV for an ankle fracture was 0.95 (95% confidence interval (CI): 0.88-0.99). The PPV for the diagnosis code was 0.89 (95% CI: 0.79-0.95), and for the procedure code, the PPV was 0.82 (95% CI: 0.70-0.90). For patients with only an ankle fracture diagnosis code or only a surgical procedure code, the PPV for an ankle fracture was 0.77 (95% CI: 0.64-0.87). CONCLUSION This study showed that ankle fracture diagnosis and procedure codes registered in the DNPR are of a high quality and thus constitute a valuable data source for research on ankle fractures. FUNDING none. TRIAL REGISTRATION The Danish Data Protection Agency approved the study (journal number 2015-18/62866).

Abstract
Objective: To provide a systematic review of the literature and knowledge base of cost per quality-adjusted life year of physical rehabilitation and care of older persons after hip fracture.Material and methods: A research librarian assisted in searching 9 databases (14 May to 27 May 2021), with exclusion of studies on cognitively impaired or institutionalized individuals. A stepwise selection process was conducted by 2 authors, study quality was assessed using Drummond et al.’s checklist, and correspondence between different countries was assessed using Welte et al.’s checklist.Results: Three studies were included, which employed 3 different interventions initiated at 3 different postoperative time-points. One high-quality study demonstrated that comprehensive geriatric assessment was cost-effective compared with coordinated care. The other 2 studies did not find the interventions studied to be cost-effective, and both studies were deemed to be of moderate quality.Conclusion: The body of evidence on the cost-effectiveness of physical rehabilitation and care after hip fracture is limited and heterogeneous, with only 1 high-quality study. Thus, stakeholders perform decision-making with a limited knowledge base of the cost-effectiveness of physical rehabilitation and care.

Abstract
In this case report a 37-year-old women, 38 weeks and four days pregnant, presented with an occult hip fracture. Before surgery, it was important to investigate the nature of the fracture as the treatment differed accordingly. The patient was investigated with MRI and following acute caesarean section a PET-CT scan was performed with no proof of malignancy. An undetectable low level of vitamin D and the pathology report determined the cause of the fracture to be transient osteoporosis of pregnancy. The patient received a total hip arthroplasty and was referred to further treatment at a department of endocrinology.

Abstract
Background Plantar fasciopathy is the most common reason for complaints of plantar heel pain and one of the most prevalent musculoskeletal conditions with a reported lifetime incidence of 10%. The condition is normally considered self-limiting with persistent symptoms that often last for several months or years. Multiple treatments are available, but no single treatment appears superior to the others. Heavy-slow resistance training and radiofrequency microtenotomy for the treatment of plantar fasciopathy have shown potentially positive effects on short- and long-term outcomes (> 3 months). However, the effect of heavy-slow resistance training compared with a radiofrequency microtenotomy treatment is currently unknown. This trial compares the efficacy of heavy-slow resistance training and radiofrequency microtenotomy treatment with supplemental standardized patient education and heel inserts in improving the Foot Health Status Questionnaire pain score after 6 months in patients with plantar fasciopathy. Methods In this randomized superiority trial, we will recruit 70 patients with ultrasound-confirmed plantar fasciopathy and randomly allocate them to one of two groups: (1) heavy-slow resistance training, patient education and a heel insert (n = 35), and (2) radiofrequency microtenotomy treatment, patient education and a heel insert (n = 35). All participants will be followed for 1 year, with the 6-month follow-up considered the primary endpoint. The primary outcome is the Foot Health Status Questionnaire pain domain score. Secondary outcomes include the remaining three domains of the Foot Health Status Questionnaire, a Global Perceived Effect scale, the physical activity level, and Patient Acceptable Symptom State, which is the point at which participants feel no further need for treatment. Discussion By comparing the two treatment options, we should be able to answer if radiofrequency microtenotomy compared with heavy-slow resistance training is superior in patients with plantar fasciopathy. Trial registration ClinicalTrials.gov NCT03854682. Prospectively registered on February 26, 2019.

Abstract
INTRODUCTION Humeral shaft fracture treatment can induce serious morbidities, and it is unclear how these morbidities impact patients. To gain in-depth knowledge, we explored how patients experience humeral shaft fractures and the subsequent treatment course. METHOD A qualitative study was performed using semi-structured individual interviews. A purposive sampling approach was conducted to recruit patients with traumatic isolated humeral shaft fractures; the patients' ages, genders, primary treatments, and complications varied. Data saturation was met after the data of 12 patients were analyzed using Malterud Systematic Text Condensation. RESULTS Eight women and four men with a median age of 48.5 years (range: 22-83 years) were interviewed. The median time from injury to interview was 12.5 months (range: 8-18 months). Ten out of twelve patients were treated non-surgically; of those ten, four patients experienced major complications from the primary treatment. During the analysis, five overarching themes appeared: expectations, physical changes, support and independence, psychological impact, and the specific treatment and recovery. CONCLUSION First, patients with humeral shaft fractures expressed frustration with treatment in the emergency department. Second, gross fracture movement and pain were central symptoms that led to the loss of basic capabilities. Third, patient preferences were included in the treatment decision-making process and could change throughout the treatment course. Fourth, patients required massive support to perform basic activities of daily living.

Abstract
BACKGROUND The outcome of non-surgical treatment is generally good, but the treatment course can be long and painful with approximately a quarter of the patients acquiring a nonunion. Both surgical and non-surgical treatment can have disabling consequences such as nerve injury, infection, and nonunion. The purpose of the study is to compare patient-reported outcomes after surgical and non-surgical treatment for humeral shaft fractures. METHODS A pragmatic randomized controlled trial (RCT) is planned with two study groups (SHAFT-Young and SHAFT-Elderly). A total of 287 eligible acute humeral shaft fractures are scheduled to be recruited and randomly allocated to surgical or non-surgical treatment with the option of early crossover due to delayed union. The surgical method within the allocation is decided by the surgeon. The primary outcome is the Disability of Arm, Shoulder, and Hand (DASH) score at 52 weeks, and is assessor blinded. The secondary outcomes are DASH score, EQ-5D-5L, pain assessed by visual analog score, Constant-Murley score including elbow range of motion, and anchor questions collected at all timepoints throughout the trial. All complications will be reported including; infection, nerve or vascular injury, surgical revisions (implant malpositioning, hardware failure, aseptic loosening, and peri-implant fracture), major adverse cardiovascular events, and mortality. DISCUSSION The SHAFT trial is a pragmatic multicenter RCT, that will compare the effectiveness of the main strategies in humeral shaft fracture treatment. This will include a variety of fracture morphologies, while taking the dilemmas within the population into account by splitting the population by age and providing the orthopedic society with an interval for early crossover surgery.

Abstract
BACKGROUND AND PURPOSE The risk of dislocation after primary total hip arthroplasty (THA) is affected by several factors, which increases the possibility of substantial differences among hospitals. We compared cumulative incidences of dislocation between regions and hospitals after primary THA surgery in osteoarthritis (OA) patients. PATIENTS AND METHODS From the Danish Hip Arthroplasty Register, we included 31,105 THAs performed from 2010 to 2014 with 2 years' follow-up. Dislocations treated by closed reduction were identified in the Danish National Patient Register combined with patient file review. The results are presented as 2-year cumulative incidence on national, regional, and hospital level as proportions with 95% confidence intervals (CI) and as adjusted odds ratios (OR) analyzed by multiple logistic regression. RESULTS 1,861 dislocations in 1,079 THAs were identified from 59 orthopedic departments. The 2-year cumulative incidence ranged from 2.2% to 4.3% between the 5 regions in Denmark. Hospital variation was 0-12%. For hospitals with a 5-year volume of more than 100 procedures, the incidence was 0.9-7.4%. Using the highest volume hospital as the reference, ORs for dislocation for the remaining hospitals were between 0.3 (CI 0.1-0.6) and 2.7 (1.9-4.0) after adjusting for age, sex, head size, and fixation method. Low-volume hospitals showed a higher dislocation risk than high-volume units with an adjusted OR of 1.2 (1.1-1.4). INTERPRETATION We found substantial variation in the incidence of dislocation between hospitals within Denmark, which can be explained by a combination of patient-, component-, and surgery-related factors. There is a need for continuous monitoring of THA dislocation on regional and hospital levels to reduce overall and local dislocation risk for future patients.

Abstract
Locking plates were initially designed to provide improved stability to ankle fractures with poor bone quality but are currently widely used. The aim of this study was to compare the reoperation risk when using locking plates compared with nonlocking plates in patients with simple ankle fractures. This study was a population-based register study. Data regarding patients with AO type 44A1/2 and 44B1/2 injuries who were treated with either locking or nonlocking plates were obtained from the Danish Fracture Database. The follow-up period was 24 months. Major complications were defined as complications requiring surgical intervention, with the exception of simple hardware removal 6 weeks after primary surgery, which was defined as a minor complication. Multivariate regression analysis was performed to determine relative risk (RR), adjusted for age, sex, American Society of Anesthesiologists physical status classification (ASA)-score, and level of the surgeon's experience. A total of 2177 ankle fractures were included, among which 718 (33%) were treated with locking plates, and 1459 (67%) were treated with nonlocking plates. Data were linked with the Danish National Patient Registry to ensure complete information was obtained regarding reoperations, which were divided into major and minor complications. In both groups, the risks for major and minor complications were 3% and 22%, respectively, resulting in adjusted RRs of 1.00 (0.66; 1.66) for major reoperation comparing locking with nonlocking plates and 0.92 (0.76; 1.11) for minor reoperations. We conclude that no significant association with reoperation exists for locking compared with nonlocking plates among patients with surgically treated simple ankle fractures.

Background A hip fracture is a serious event for older adults, given that approximately 50% do not regain their habitual level of physical function, and the mortality rate is high, as is the number of readmissions. The gap in healthcare delivery, as separated into two financial and self-governing sectors, might be a contributing cause of inferior rehabilitation and care for these patients. Therefore, we aim to assess the effect of continuous and progressive rehabilitation and care across sectors for older adults after hip fracture. Methods/design The project is designed as a stepped-wedge cluster randomised controlled trial. The study population of patients are older adults 65 years of age and above discharged after a hip fracture and healthcare professionals in primary and secondary care (municipalities and hospitals). Healthcare professionals from different sectors (hospital and municipalities) will be engaged in the empowerment-orientated praxis, through a workshop for healthcare professionals with knowledge sharing to the older adults using a digital health application (app). The rehabilitation intervention consists of 12 weeks of progressive resistance exercises initiated 1–2 days after discharge. To improve communication across sectors, a videoconference involving the patient and physiotherapists from both sectors will be conducted. On day, 3 after discharge, an outreach nurse performs a thorough assessment including measurement of vital signs. A hotline to the hospital for medical advice is a part of the intervention. The intervention is delivered as an add-on to the usual rehabilitation and care, and it involves one regional hospital and the municipalities within the catchment area of the hospital. The primary outcome is a Timed Up and Go Test 8 weeks post-surgery. Discussion Using a stepped-wedge design, the intervention will be assessed as well as implemented in hospital and municipalities, hopefully for the benefit of older adults after hip fracture. Furthermore, the collaboration between the sectors is expected to improve. Trial registration The study is approved by the Regional Scientific Ethics Committees of Southern Denmark (S-20200070) and the Danish Data Protection Agency (20-21854).

Abstract
UNLABELLED Research on younger patients with hip fractures is limited. This study adds knowledge on patient and injury characteristics, and DXA was investigated at the time of the fracture. Risk factors for osteoporosis and fractures were numerous among young patients, and osteoporosis was markedly more prevalent than in the general population. INTRODUCTION Knowledge on younger patients with hip fractures is limited. Common preconceptions are that they suffer fractures due to high-energy trauma, alcohol or substance use disorder but not associated to osteoporosis. We aimed to descriptively analyze the characteristics of young and middle-aged patients with hip fractures and examine bone mineral density (BMD) by dual-energy x-ray absorptiometry (DXA) at the time of the fracture. METHODS A prospective multicenter cohort study on adult patients with hip fractures below age 60 collected detailed information on patient characteristics regarding demographics, trauma mechanism, previous fractures, comorbidity and medication, and lifestyle factors. DXA results were compared to population-based reference data. RESULTS The cohort contains 91 women and 127 men, median age 53 (IQR 47-57). Most fractures, 83%, occurred in patients aged 45-59. Two-thirds of all fractures resulted from low-energy trauma. Half of the patients had prior fractures after age 20. Thirty-four percent were healthy, 31% had one previous disease, and 35% had multiple comorbidities. Use of medication associated with increased fracture risk was 32%. Smoking was prevalent in 42%, harmful alcohol use reported by 29%, and signs of drug-related problems by 8%. Osteoporosis according to WHO criteria was found in 31%, osteopenia in 57%, and normal BMD in 12%. CONCLUSION In patients with hip fractures below age 60, risk factors for osteoporosis and fractures were numerous. Moreover, the prevalence of osteoporosis was markedly higher than in the general population. We suggest that young and middle-aged patients with hip fractures undergo a thorough health investigation including DXA, regardless of trauma mechanism.

Knee 2022; 35:1-7. [PMID: 35144195 DOI: 10.1016/j.knee.2022.01.007] [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: 04/16/2021] [Revised: 01/17/2022] [Accepted: 01/23/2022] [Indexed: 02/02/2023]
Abstract
BACKGROUND Studies with less than 10 years of follow-up have demonstrated no difference between surgical and non-surgical treatment after an anterior cruciate ligament (ACL) rupture; however, long-term effects remain unclear. The aim of this study was to compare the risk of long-term secondary surgical procedures after primary surgical and non-surgical treatment for ACL ruptures. METHODS Patients aged 18-35, registered in the Danish National Patient Registry with an ACL rupture between January 1, 1996 and December 31, 2000 with a minimum of 20 years follow-up were included. The surgically treated group was defined as receiving an ACL reconstruction within 1 year after diagnosis. Major secondary surgical procedures were defined as subsequent ACL surgeries (reconstruction/revision), arthroplasty, deep infection, arthrodesis, or amputation. Minor secondary surgical procedures were defined as meniscal surgery, synovectomy, and manipulation under anesthesia (MUA). Multivariate regression analysis was performed to assess relative risk (RR), adjusted for age and sex. The results are reported with 95% confidence intervals. RESULTS 7,539 patients had an ACL rupture; 1,970 patients were surgically treated. In the surgically treated group, 5.9% of patients underwent major secondary surgeries; this was 6.1% in the non-surgically treated group, yielding an adjusted RR of 1.05 (0.85;1.30). There were 43.9% minor secondary surgeries in the surgically treated group and 49.1% in the non-surgically treated group, yielding an adjusted RR of 1.29 (1.20;1.39). CONCLUSIONS No significant differences in the rate of major secondary surgical procedures between the groups, the non-surgical group was associated with a higher risk of minor secondary surgeries.

Abstract
OBJECTIVE to conduct a systematic review with consequent meta-analysis evaluating the best treatment for Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) 31A1-A3 trochanteric fractures when comparing the sliding hip screw (SHS) to the intramedullary nail (IMN). The outcomes used for comparison are major complications (in total, as well as nonunion and infection specifically), mortality rates, functional outcomes and patient-reported outcome measures (PROM). MATERIALS AND METHODS Search strings for the Cochrane Library, CINAHL, Medline and Embase databases were developed with the help of a scientific librarian. Two authors screened the studies from the search string independently using Covidence.org and data extraction was performed similarly. Quality assessment was performed using the Cochrane Risk of Bias tool for randomised trials (ROB2) for RCT studies, and Cochrane Risk of Bias in Non-Randomised Studies - of Interventions (ROBINS-I) for non-RCT studies. Meta-analyses were performed using Log Risk Ratio as the primary effect estimate. RESULTS Of the 2,051 studies screened by the two authors, six RCTs and six non-RCTs were included in this meta-analysis, with a total of 10,402 patients. The results indicated no significant differences in total major complications, nonunion, infection or mortality between SHS and IMN treatments for AO/OTA 31A1, 31A2 and 31A3 trochanteric fractures. Due to a lack of compatible data, we were unable to perform a meta-analysis on function scores and PROM. However, there are trends that favour IMN for 31A1 and 31A2 fractures. CONCLUSION No significant difference between SHS and IMN was found in the meta-analysis in any of the examined AO/OTA fracture subtypes in terms of primary and secondary outcomes. When assessing function scores and PROM, we found trends favouring IMN for 31A1 and 31A2 fractures that should be explored further.

Abstract
AIMS The aim of this study was to assess the association of mortality and reoperation when comparing cemented and uncemented hemiarthroplasty (HA) in hip fracture patients aged over 65 years. METHODS This was a population-based cohort study on hip fracture patients using prospectively gathered data from several national registries in Denmark from 2004 to 2015 with up to five years follow-up. The primary outcome was mortality and the secondary outcome was reoperation. Hazard ratios (HRs) for mortality and subdistributional hazard ratios (sHRs) for reoperations are shown with 95% confidence intervals (CIs). RESULTS A total of 17,671 patients with primary HA were identified (9,484 uncemented and 8,187 cemented HAs). Compared to uncemented HA, surgery with cemented HA was associated with an absolute risk difference of 0.4% for mortality within the period zero to one day after surgery and an adjusted HR of 1.70 (95% CI 1.22 to 2.38). After seven days, there was no longer any association, with an adjusted HR of 1.07 (95% CI 0.90 to 1.28). This continued until five years after surgery with a HR of 1.01 (95% CI 0.96 to 1.06). There was a higher proportion of reoperations due to any reason after five years in the uncemented group with 10.2% compared to the cemented group with 6.1%. This yielded an adjusted sHR of 0.65 (95% CI 0.57 to 0.75) and difference continued up until five years after the surgery, demonstrating a sHR of 0.70 (95% CI 0.59 to 0.83). CONCLUSION In a non-selected cohort of hip fracture patients, surgery with cemented HA was associated with a higher relative mortality during the first postoperative day compared to surgery with uncemented HA, but there was no difference after seven days up until five years after. In contrast, surgery with cemented HA was associated with lower risk of reoperation up to five years postoperatively compared with surgery with uncemented HA. There was a higher relative mortality on the first postoperative day for cemented HA versus uncemented HA. There was no difference in mortality after seven days up until five years after surgery. There were 6.1% reoperations for cemented HA compared to 10.2% for uncemented HA after five years. Cite this article: Bone Joint J 2022;104-B(1):127-133.

Abstract
BACKGROUND The purpose of the present multicenter cohort study was to compare the rates of reoperation in elderly patients with pertrochanteric and subtrochanteric fractures that had been treated with a short or long intramedullary nail. METHODS Eleven orthopaedic departments across Denmark delivered data that had been obtained from the Danish Multidisciplinary Hip Fracture Registry (DMHFR) and a review of health-care records. With use of surgical procedure codes for pertrochanteric and subtrochanteric fractures that had been treated with an intramedullary nail, the DMRHF was searched to identify patients who had been ≥65 years of age between 2008 and 2013. The health-care records for patients who had had major reoperations, defined as any reoperation with the exclusion of simple hardware removal, were retrieved from the DMHFR, were reviewed for the type of intramedullary nail and missed reoperations, including peri-implant fractures, within 2 years of follow-up. Crude logistic regression analysis with adjustment for age, sex, and comorbidity was performed, yielding odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS Of 2,245 pertrochanteric fractures, 1,867 were treated with a short intramedullary nail and 378 were treated with a long intramedullary nail. The rate of major reoperations was 4.0% in the short intramedullary nail group and 6.3% in the long intramedullary nail group. This yielded a crude OR of 1.61 (1.01 to 2.60) and an adjusted OR of 1.67 (1.04 to 2.70). Of 909 subtrochanteric fractures, 308 were treated with a short intramedullary nail and 601 were treated with a long intramedullary nail. The rate of major reoperations was 8.4% in the short intramedullary nail group and 4.0% in the long intramedullary nail group, yielding a crude OR of 0.45 (0.25 to 0.80) and an adjusted OR of 0.45 (0.25 to 0.81). CONCLUSIONS This is the first study confirming the theory that, for subtrochanteric fractures, a long intramedullary nail has a lower rate of major reoperations compared with a short intramedullary nail. In contrast, a short intramedullary nail has a lower rate of major reoperations compared with a long intramedullary nail for pertrochanteric fractures but with a lower absolute risk reduction compared with the results for subtrochanteric intramedullary nailing. There is a need for validation of these results in other large studies, especially for pertrochanteric fractures. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
Tranexamic acid (TXA) has been studied extensively during the last 5-8 years. It inhibits clot dissolution during surgery and can therefore reduce blood loss. However, there has been concern that this could result in more frequent complications, specifically in terms of thromboembolic events. The indications for TXA are widespread, and this review covers the literature on orthopaedic indications such as joint replacement, fracture surgery, and arthroscopic procedures. In general, TXA is safe and can be used in a wide variety of orthopaedic procedures, lowering blood loss without increasing the risk of complications.

Abstract
OBJECTIVES To assess the effect of enhanced standardized interdisciplinary cooperation between the orthogeriatric ward, municipality, and nursing home facility (NHF) on readmission rates in patients with hip fracture. DESIGN Quasi-experimental design with a nonequivalent control group. SETTING AND PARTICIPANTS From January 2018 to July 2020, patients with hip fracture who were admitted to the department of orthopedic surgery and traumatology at Lillebaelt Hospital, and later discharged to NHF were included. INTERVENTION The intervention consisted of a safety program to the NHF for the first 14 days postdischarge and included assessment of vital signs, weight, pain, signs of constipation, hours of mobilization, and daily intake of fluids and high-protein beverages. Acute team nurses undertook visits (planned and unplanned) and could take blood samples and administer intravenous fluids or antibiotics at the NHF. Control participants received usual care. METHODS The intervention was performed in 2 municipalities with an acute team; the remaining 3 municipalities comprised the control group. The primary outcome was 30-day readmission, and secondary outcomes were mortality, mobility, and quality of life. RESULTS There were 100 patients in the intervention group and 152 in the control group. The median age was 86 years, 68% were female, and more than 60% had a low mental score; there were no statistical differences between groups in baseline variables. The 30-day readmission rate was 14% in the intervention group and 30% in the control group (P = .004). The 30-day mortality rate was 6% in the intervention group and 13% in the control group (P = .07). There was no statistically significant difference in mobility between the 2 groups but there was a higher health-related quality of life score in the intervention group (P = .045). CONCLUSIONS AND IMPLICATIONS Enhanced standardized interdisciplinary cooperation between hospital, NHF teams, and visiting acute team nurses can lower readmissions and potentially mortality.
