Setting proficiency standards for simulation-based mastery learning of short antegrade femoral nail osteosynthesis: a multicenter study.

BACKGROUND AND PURPOSE: Orthopedic trainees frequently perform short antegrade femoral nail osteosynthesis of trochanteric fractures, but virtual reality simulation-based training (SBT) with haptic feedback has been unavailable. We explored a novel simulator, with the aim of gathering validity evidence for an embedded test and setting a credible pass/fail standard allowing trainees to practice to proficiency. PATIENTS AND METHODS: The research, conducted from May to September 2020 across 3 Danish simulation centers, utilized the Swemac TraumaVision simulator for short antegrade femoral nail osteosynthesis. The validation process adhered to Messick's framework, covering all 5 sources of validity evidence. Participants included novice groups, categorized by training to plateau (n = 14) or to mastery (n = 10), and experts (n = 9), focusing on their performance metrics and training duration. RESULTS: The novices in the plateau group and experts had hands-on training for 77 (95% confidence interval [CI] 59-95) and 52 (CI 36-69) minutes while the plateau test score, defined as the average of the last 4 scores, was 75% (CI 65-86) and 96% (CI 94-98) respectively. The pass/fail standard was established at the average expert plateau test score of 96%. All novices in the mastery group could meet this standard and interestingly without increased hands-on training time (65 [CI 46-84] minutes). CONCLUSION: Our study provides supporting validity evidence from all sources of Messick's framework for a simulation-based test in short antegrade nail osteosynthesis of intertrochanteric hip fracture and establishes a defensible pass/fail standard for mastery learning of SBT. Novices who practiced using mastery learning were able to reach the pre-defined pass/fail standard and outperformed novices without a set goal for external motivation.

Acute foot attack in patients with diabetes requires urgent action.

This review summarises the present knowledge of acute foot attacks in patients with diabetes. Diagnosis and treatment of acute foot attacks in patients with diabetes are often delayed, which increases the risk of amputations. To prevent this, urgent action is necessary, as it is for acute myocardial infarction and stroke, to ensure that patients are seen by competent specialists in a multidisciplinary team within hours. By following evidence-based guidelines, such as the National Treatment Guideline for diabetic foot disease from the Danish Endocrine Society, and seeking immediate medical attention, the risk of amputation and complications can be significantly reduced.

Incidence of dislocation and associated risk factors in patients with a femoral neck fracture operated with an uncemented hemiarthroplasty.

BACKGROUND: Several factors might be associated with risk of dislocating following uncemented hemiarthroplasty (HA) due to femoral neck fracture (FNF). Current evidence is limited with great variance in reported incidence of dislocation (1-15%). Aim of this study was to identify the cumulative incidence of first-time dislocation following HA and to identify the associated risk factors. METHOD: We performed a retrospective cohort study of patients receiving an HA (BFX Biomet stem, posterior approach) at Copenhagen University Hospital, Bispebjerg, in 2010-2016. Patients were followed until death or end of study (dec 2018). Dislocation was identified by code extraction from the Danish National Patient Registry. Variables included in the multivariate model were defined pre-analysis to include: age, sex and variables with a p-value < 0.1 in univariate analysis. A regression model was fitted for 90 days dislocation as the assumption of proportional hazard rate (HR) was not met here after. RESULTS: We identified 772 stems (some patients occurred with both right and left hip) and 58 stems suffered 90 dislocations during the observation period, resulting in a 7% (CI 5-9) incidence of dislocation 90 days after index surgery. 55 of the 58 stems (95%) experienced the first dislocation within 90 days after surgery. Only absence of dementia was identified as an independent protective factor in the cause-specific model (HR 0.46 (CI 0.23-0.89)) resulting in a 2.4-fold cumulative risk of experiencing a dislocation in case of dementia. Several other variables such as age, sex, various medical conditions, surgery delay and surgical experience were eliminated as statistical risk factors. We found a decrease in survival probability for patients who experienced a dislocation during follow-up. CONCLUSIONS: The incidence of first-time dislocation of HA (BFX Biomet stem, posterior approach) in patients with a hip fracture is found to be 7% 90 days after surgery. Due to the non-existing attribution bias, we claim it to be the true incidence. Dementia was among several variables identified as the only risk factor for dislocation. In perspective, we may consider treating patients with dementia by other methods than HA e.g., HA with cement or with a more constrained solution. Also, a surgical approach that reduce the risk of dislocation should be considered.

Incidence, Quality of Care, and Mortality in Hip Fracture Patients in the Course of the COVID Pandemic: A Population-Based Cohort Study.

BACKGROUND: We assessed the incidence, quality of in-hospital care, and mortality for hip fracture (HF) patients in Denmark before and during the coronavirus disease (COVID) pandemic. METHODS: We obtained data from the Danish registries in the COVID period (March 11, 2020 to January 27, 2021, overall and in 5 periods) and compared it to a pre-COVID period (March 13, 2019 to March 10, 2020). We calculated the proportion of patients (%) that have fulfilled all the relevant quality indicators (a composite score of 100%) and adjusted hazard ratios (HR) with a 95% confidence interval (CI) for 30-day mortality. RESULTS: The incidence of HF was 5.7 per 1 000 person-years both in pre-COVID and COVID periods. About 35% of patients had a composite score of 100% in the COVID period compared to 28% in the pre-COVID period (proportion ratio 1.23 [95% CI: 1.17-1.30]). Fulfillment of all individual quality indicators was similar or higher in the COVID period. 30-day mortality was 9.5% in pre-COVID period, compared to 10.8% in the COVID period (HR 1.15 [95% CI: 1.02-1.30]). HRs varied from 1.07 (95% CI: 0.89-1.29) to 1.31 (95% CI: 1.06-1.62) in 5 COVID periods. In-hospital mortality was 4% in pre-COVID versus 4.4% in COVID period. CONCLUSIONS: The incidence of HF in Denmark remained unchanged. The quality of in-hospital care was higher in the COVID compared to pre-COVID period. Unfortunately, 30-day mortality was also higher, highlighting the importance of recognizing diversity of social networks, home support, and digital health intervention after discharge for outcome of HF patients.

A clinical guide to the medial ligaments of the ankle: Anatomy, function, diagnosis of injuries and treatment of instability-a narrative review.

BACKGROUND: The aim was to provide an update on anatomy and function of the medial ankle ligaments, diagnosis of their injuries and treatment of medial ankle instability. METHODS: Literature search on PubMed. RESULTS: Injuries to the deltoid ligament are not uncommon in relation to malleolar fractures and ankle sprains. Chronic instability may lead to ankle osteoarthritis. However, there is no consensus on diagnostic criteria (clinically, by imaging and by arthroscopy), on indications for non-operative and operative treatment, and on standards for repair and reconstruction of the ligament complex. There is no current evidence to support acute repair of deltoid ligament injury. Reports on the effect of isolated deltoid ligament reconstruction are very sparse. CONCLUSION: There is a need for a focused effort to establish evidence for all aspects of deltoid ligament injury.

Intensified acute in-hospital physiotherapy for patients after hip fracture surgery: a pragmatic, randomized, controlled feasibility trial.

PURPOSE: Intensified acute in-hospital physiotherapy (IP) after hip fracture (HF) may enhance patient's ability to regain basic mobility at discharge. The primary objective was to assess the feasibility of IP. Secondary to estimate the effect of IP on regained basic mobility at discharge. MATERIALS AND METHODS: In a pragmatic, randomized, unblinded feasibility trial, 60 patients (mean age 79 years, 41 women) with HF and an independent pre-fracture basic mobility level were randomized (2:1) to IP with two daily sessions on weekdays focusing on functional training and weight-bearing activities (n = 40) versus usual care (UC) physiotherapy once daily (n = 20). Feasibility outcomes included physiotherapy completion rates, reasons for non-successful completion, and adverse events. The primary effect outcome was recovery of basic mobility (Cumulated Ambulation Score (CAS)). RESULTS: Eighty-two percent of the sessions in the IP group were successfully- or partially completed versus 94% of the sessions in the UC group. No adverse events occurred. The main reason for not completing physiotherapy was fatigue. At discharge (median 7 days), 50% in the IP group had regained their pre-fracture basic mobility level (CAS = 6) versus 16% in the UC group; odds ratio = 5.33, 95%CI [1.3;21.5]. CONCLUSIONS: IP seems feasible for patients after HF surgery, and it may enhance recovery. Fatigue was the primary obstacle to completing IP.

Two daily physiotherapy sessions focusing on functional training and weight-bearing activities are feasible for patients after isolated hip fracture surgery, including subtrochanteric fracture, and may enhance recovery of basic mobility at discharge.During hospitalization, patient participation in intensified physiotherapy is mainly restricted by fatigue.Systematic assessment and management of fatigue may improve the completion of physiotherapy and recovery of basic mobility.

No effect of hydroxyapatite-coated sliding hip screw threads on screw migration in the femoral head/neck of pertrochanteric fractures: a randomized controlled trial using radiostereometric analysis.

INTRODUCTION: Cut-out is the most frequently reported mechanical failure of internal fixation of pertrochanteric fractures. The purpose of this study was to examine if hydroxyapatite-coated screw thread on a sliding hip screw (SHS) could reduce screw migration within the femoral head in patients with stable pertrochanteric fractures. MATERIALS AND METHODS: In a double-blinded randomized controlled study, 37 patients at mean age 78 (range 56-96), with pertrochanteric fracture (Evans I, II, IV) received surgery with a SHS with a hydroxyapatite-coated or a non-coated lag screw thread. Radiostereometry and standard radiographs were obtained 1 day, 6 weeks, 3- and 6 months post-operatively to evaluate screw and fracture migration and fracture reposition. The two groups were combined to describe fracture migration. RESULTS: There was similar and small screw migration in the femoral head between the two groups at 6 weeks, 3- and 6 months (p > 0.12). Fracture migration occurred predominantly in the first 6 weeks, where fracture impaction was 5.95 mm (CI 95% 2.87 to 9.04) and anterior rotation of the femoral head was -2.94° (CI 95% - 5.22 to - 0.66). Migration of the fracture (total translation) correlated to the post-operative fracture reposition (p = 0.002), but not significantly to screw migration (p = 0.09). Neither screw total translation (rho 0.06, p = 0.79) nor fracture total translation (rho 0.04, p = 0.77) correlated with bone mineral density. CONCLUSION: There was no clinical benefit of hydroxyapatite coating on lag screw migration in this patient cohort. Migration of the pertrochanteric fractures was higher with poor fracture reposition but fractures generally stabilized after 6 weeks follow-up. The study was registered at ClinicalTrials.gov (NCT05677061). LEVEL OF EVIDENCE II: Patient-blinded prospective randomized study. Trial registration number The study was registered at ClinicalTrials.gov (NCT05677061).

Amputations in Denmark in patients with diabetes.

In Denmark, the incidence rate of lower extremity amputations (LEA) in patients with diabetes has decreased remarkably from 1980 to 2017, in contrast to USA, where it has increased in the last decade. In this review the development in Denmark is summarised. In fact, in 2017, the incidence rate of LEA in patient with diabetes was "only" two-4 four-fold larger than in persons without diabetes. Evidence-based guidelines, like the national treatment guideline from the Danish Endocrine Society, must be followed by health-care providers and patients to further decrease the incidence rate of LEA.

A piriformis-preserving posterior approach reduces dislocation rate of the hemiarthroplasty in patients with femoral neck fracture.

INTRODUCTION: The posterior approach (PA) for hemiarthroplasty (HA) in patients with femoral neck fracture (FFN) has a high risk of dislocation; however, by preserving the piriformis muscle, the dislocation rate could be lowered considerably. The aim of this study was to compare the surgical complications of the piriformis-preserving posterior approach (PPPA) and the PA in patients with FNF treated with HA. METHODS: On 1 January 2019, the PPPA was introduced at two hospitals as the new treatment standard. The sample size was calculated based on a 5 percentage point dislocation reduction and 25% censoring; a sample of 264 patients per group was determined. An approximately 2-year inclusion period with 1-year follow-up was estimated, including a historical cohort from 2 years before the PPPA introduction. Data were retrieved from health care records and X-ray images from the hospitals' administrative databases. Relative risk (RR) and 95% confidence intervals were calculated using Cox regression and adjusted for age, sex, comorbidity, smoking, surgeon experience and implant type. RESULTS: There were 527 patients included in the study, of which 72% were women and 43% were above 85 years old. There were no baseline differences between the PPPA and PA groups in sex, age, comorbidity, body mass index, smoking, alcohol, mobility, length of surgery, blood loss or implant positioning, but there were differences in 30-day mortality, surgeon experience and implant type. The dislocation rate reduced from 11.6% in the PA group to 4.7% in the PPPA group (p = 0.004), with an RR of 2.5 (1.2; 5.1). The reoperation rate reduced from 6.8% with the PA to 3.3% with the PPPA (p = 0.022), with an RR of 2.1 (0.9; 5.2), and total surgery-related complications reduced from 14.7% with the PA to 6.9% with the PPPA (p = 0.003), with an RR of 2.4 (1.3; 4.4). INTERPRETATION: Changing from PA to PPPA in patients with FNF treated with HA resulted in a more than 50% reduction in dislocation and reoperation rates. This approach was easily introduced and may enable further lowering of dislocation rates through the sparing of all short external rotators.

Physical activity in young hip fracture patients is associated with health-related quality of life and strength; results from a multicenter study.

BACKGROUND: The World Health Organization recommends a minimum of 150 min of moderate intensity exercise per week or 75 min of strenuous activity weekly for adults. Younger hip fracture patients are often assumed less active than the general population, however, knowledge on physical activity (PA) and health-related quality of life (HRQoL) in younger hip fracture patients is limited. OBJECTIVES: We aimed to 1) investigate the variation in pre-fracture PA for adult patients with hip fractures under the age of 60; and 2) to quantify the association with patient characteristics, including outcomes of HRQOL and handgrip strength. DESIGN AND METHODS: A prospective multicenter cohort study of 207 adult hip fracture patients under 60 years admitted to four study hospitals from July 2015 to December 2018. Data was collected through medical records, questionnaires, physical tests and interviews. PA level was assessed using a validated questionnaire from the Swedish National Board of Health and Welfare, providing a total score from 3 to 19. A score ≥11 corresponds to fulfillment of the WHO recommendation for weekly PA. Handgrip strength was measured in kilograms using a handheld dynamometer following a standardized protocol. Recall pre-fracture HRQoL was assessed using the EQ-5D-3L questionnaire. RESULTS: Fifty-nine percent had a PA score ≤10 out of these 46% had an ASA grade of 3 or 4, 38% had a BMI over 25 and 81% had a low energy fracture. A PA score ≤10 was associated with a lower HRQoL compared to those who had a PA score ≥11. PA score ≤10 points was associated with weaker hand grip strength and a worse health status (higher ASA-grade) p<0.001. CONCLUSION: We found that close to two-thirds of the patients had a pre-fracture PA level below WHO recommendations. Being more active was associated with better handgrip strength, HRQoL, and ASA score. Our findings indicate that individuals under 60 years who sustain a hip fracture form a heterogeneous group, some severely comorbid and others highly active and seemingly healthy. This suggests a more nuanced approach to rehabilitation, as the more active patient might need a more individualized plan than the standard program can offer.

Continuous Glucose Monitoring Reveals Perioperative Hypoglycemia in Most Patients With Diabetes Undergoing Major Surgery: A Prospective Cohort Study.

OBJECTIVE: To investigate the frequency and duration of hypo- and hyperglycemia, assessed by continuous glucose monitoring (CGM) during and after major surgery, in departments with implemented diabetes care protocols. SUMMARY BACKGROUND DATA: Inadequate glycemic control in the perioperative period is associated with serious adverse events, but monitoring currently relies on point blood glucose measurements, which may underreport glucose excursions. METHODS: Adult patients without (A) or with diabetes [non-insulin-treated type 2 (B), insulin-treated type 2 (C) or type 1 (D)] undergoing major surgery were monitored using CGM (Dexcom G6), with an electrochemical sensor in the interstitial fluid, during surgery and for up to 10 days postoperatively. Patients and health care staff were blinded to CGM values, and glucose management adhered to the standard diabetes care protocol. Thirty-day postoperative serious adverse events were recorded. The primary outcome was duration of hypoglycemia (glucose <70 mg/dL). Clinicaltrials.gov: NCT04473001. RESULTS: Seventy patients were included, with a median observation time of 4.0 days. CGM was recorded in median 96% of the observation time. The median daily duration of hypoglycemia was 2.5 minutes without significant difference between the 4 groups (A-D). Hypoglycemic events lasting ≥15 minutes occurred in 43% of all patients and 70% of patients with type 1 diabetes. Patients with type 1 diabetes spent a median of 40% of the monitoring time in the normoglycemic range 70 to 180 mg/dL and 27% in the hyperglycemic range >250 mg/dL. Duration of preceding hypo- and hyperglycemia tended to be longer in patients with serious adverse events, compared with patients without events, but these were exploratory analyses. CONCLUSIONS: Significant duration of both hypo- and hyperglycemia was detected in high proportions of patients, particularly in patients with diabetes, despite protocolized perioperative diabetes management.

Peripheral nerve-blocks and associations with length of stay and readmissions in fast-track total hip and knee arthroplasty.

BACKGROUND: Peripheral nerve blocks (PNB) have recently been recommended in total hip (THA) and knee (TKA) arthroplasty as they may reduce pain, morphine consumption, length of stay (LOS) and complications. However, whether PNBs are associated with early discharge within an enhanced recovery protocol including multimodal analgesia is uncertain. METHODS: An observational multicenter study from January to August 2017 in six Danish Arthroplasty Centers with established fast-track protocols. Prospective recording of preoperative characteristics and information on PNB, LOS and readmissions through the Danish National Patient Registry and medical records. Multiple logistic regression was used to investigate associations between PNB and a LOS >1 day, LOS >4 days, and 30-days readmissions. We also reported on mobilization, pain, opioid and fall-related complications leading to LOS >4 days or readmissions. RESULTS: A total of 2027 (58.6%) THA and 1432 (41.4%) TKAs with a median LOS of 1 day (IQR 1-2) and 5.3% (CI:4.6-6.1) 30-days readmission rate were identified. PNB was used in 40.7% (CI:38.2-43.3) of TKA and 2.7% (CI:2.0-3.5) of THA, but with considerable interdepartmental variation (0.0-89.0% for TKA). There was no association between PNB and LOS >1 day (OR:1.19 CI:0.82-1.72; p = .354), LOS >4 days (OR:1.4 CI:0.68-2.89; p = .359) or 30-days readmissions (OR:1.02 CI:0.63-1.65; p = .935) in TKA. Logistic regression in THA was not possible due to limited use of PNB. In TKA there were 12 (2.1% CI:1.2-3.6) with and 1 (0.1% CI:0.02-0.7) without a PNB, who had mobilization, pain or opioid-related complications, and 5 (0.9% CI:0.4-2.0) versus 4 (0.5% CI:0.2-1.2) who fell. Correspondingly, 2 (3.7% CI:1.0-12.6) and 11 (0.6% CI:0.3-1.0) of THA patients had these complications, while 0 (0.0% CI:0.0-6.6) and 17 (0.8% CI:0.5-1.3) fell. CONCLUSION: Routine use of peripheral nerve blocks was not associated with early discharge or 30-days readmissions in fast-track THA and TKA. Future studies should focus on benefits of PNB in high-risk patients.

Effectiveness of promotion and support for physical activity maintenance post total hip arthroplasty-study protocol for a pragmatic, assessor-blinded, randomized controlled trial (the PANORAMA trial).

BACKGROUND: Total hip arthroplasty is considered an efficacious procedure for relieving pain and disability, but despite that objectively measured physical activity level remains unchanged compared to pre-surgery and is still considerably lower than that of a healthy age- and sex-matched population 6-12 months post-surgery. Since there is a graded relationship between physical activity level and functional performance, increasing physical activity may enhance the outcome of the procedure. This study aims to investigate whether promotion and support of physical activity initiated 3 months after total hip arthroplasty complementary to usual rehabilitation care can increase objective measured physical activity 6 months post-surgery. METHODS: The trial is designed as a pragmatic, parallel group, two-arm, assessor-blinded, superiority, randomized (1:1), controlled trial with post intervention follow-up 6 and 12 months after total hip arthroplasty. Home-dwelling, independent, and self-reliant patients with hip osteoarthritis are provisionally enrolled prior to surgery and re-screened about 2-3 months post-surgery to confirm eligibility. Baseline assessment is conducted 3 months post-surgery. Subsequently, patients (n=200) are randomized to either a 3-month, multimodal physical activity promotion/education intervention or control (no further attention). The intervention consists of face-to-face and telephone counselling, patient education material, pedometer, and step-counting journal. The primary outcome is objectively measured physical activity, specifically the proportion of patients that complete on average ≥8000 steps per day 6 months post-surgery. Secondary outcomes include core outcomes (i.e., physical function, pain, and patient global assessment) and health-related quality of life. Furthermore, we will explore the effect of the intervention on self-efficacy and outcome expectations (i.e., tertiary outcomes). DISCUSSION: By investigating the effectiveness of a pedometer-driven, face-to-face, and telephone-assisted counselling, behavior change intervention in complementary to usual rehabilitation, we hope to deliver applicable and generalizable knowledge to support physical activity after total hip arthroplasty and potentially enhance the outcome of the procedure.

Profiling Bispebjerg Acute Cohort: Database Formation, Acute Contact Characteristics of a Metropolitan Hospital, and Comparisons to Urban and Rural Hospitals in Denmark.

Purpose: To present a metropolitan cohort, Bispebjerg acute cohort (BAC), and compare patient characteristics and outcomes with patients from urban and rural hospitals in Denmark. Patients and Methods: We linked data from seven Danish nationwide registries and included all acute contacts to non-psychiatric hospitals in the years 2016-2018. Acute hospital contacts to Bispebjerg and Frederiksberg Hospital constituted BAC, representing a solely metropolitan/urban catchment area. Patient characteristics and outcomes were compared to the rest of Denmark in an urban cohort (UrC) and a rural cohort (RuC), stratified by visit and hospitalization contact types. Results: We identified 4,063,420 acute hospital contacts in Denmark and BAC constituted 8.4% (n=343,200) of them. BAC had a higher proportion of visits (65.1%) compared with UrC (52.1%) and RuC (45.3%). Patients in BAC more often lived alone (visits: BAC: 34.8%, UrC: 30.6%, RuC: 29.2%; hospitalizations: BAC: 50.8%, UrC: 36.7%, RuC: 37.2%) and had temporary CPR number (visits: BAC: 4.4%, UrC: 1.9%, RuC: 1.6%; hospitalizations: BAC: 1.5%, UrC: 0.9%, RuC: 0.8%). Visit patients in BAC were younger (BAC: 36, UrC: 42, RuC: 45 years, median), more often students (BAC: 18.0%, UrC: 14.0%, RuC: 12.5%), and had more contacts due to infectious diseases (BAC: 19.8%, UrC: 14.1%, RuC: 6.2%) but less due to injuries (BAC: 40.0%, UrC: 43.8%, RuC: 60.7%). Hospitalized patients in BAC had higher median age (BAC: 64, UrC: 61, RuC: 64 years) and fewer were in employment than in UrC (BAC: 26.1%, UrC: 32.1%, RuC: 28.1%). BAC Hospitalizations had a lower death rate within 30 days than in RuC (BAC: 3.0% [2.9-3.1%], UrC: 3.1% [3.0-3.1%], RuC: 3.4% [3.3-3.4%]), but a higher readmission-rate (BAC: 20.5% [20.3-20.8%], UrC: 17.3% [17.2-17.4%], RuC: 17.5% [17.5-17.6%]). Conclusion: Significant differences between BAC, urban, and rural cohorts may be explained by differences in healthcare structure and sociodemographics of the catchment areas.

Frailty and osteoporosis in patients with hip fractures under the age of 60-a prospective cohort of 218 individuals.

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.

Sliding hip screw vs intramedullary nail for AO/OTA31A1-A3: a systematic review and meta-analysis.

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.

Quality indicators in the treatment of geriatric hip fractures: literature review and expert consensus.

PURPOSE: Even though hip fracture care pathways have evolved, mortality rates have not improved during the last 20 years. This finding together with the increased frailty of hip fracture patients turned hip fractures into a major public health concern. The corresponding development of an indicator labyrinth for hip fractures and the ongoing practice variance in Europe call for a list of benchmarking indicators that allow for quality improvement initiatives for the rapid recovery of fragile hip fractures (RR-FHF). The purpose of this study was to identify quality indicators that assess the quality of in-hospital care for rapid recovery of fragile hip fracture (RR-FHF). METHODS: A literature search and guideline selection was conducted to identify recommendations for RR-FHF. Recommendations were categorized as potential structure, process, and outcome QIs and subdivided in-hospital care treatment topics. A list of structure and process recommendations that belongs to care treatment topics relevant for RR-FHF was used to facilitate extraction of recommendations during a 2-day consensus meeting with experts (n = 15) in hip fracture care across Europe. Participants were instructed to select 5 key recommendations relevant for RR-FHF for each part of the in-hospital care pathway: pre-, intra-, and postoperative care. RESULTS: In total, 37 potential QIs for RR-FHF were selected based on a methodology using the combination of high levels of evidence and expert opinion. The set consists of 14 process, 13 structure, and 10 outcome indicators that cover the whole perioperative process of fragile hip fracture care. CONCLUSION: We suggest the QIs for RR-FHF to be practice tested and adapted to allow for intra-hospital longitudinal follow-up of the quality of care and for inter-hospital and cross-country benchmarking and quality improvement initiatives.
