Objectives: To identify and compare characteristics of patients with hip fracture treated nonoperatively versus those treated operatively., Design: Retrospective cohort study., Setting: Hip fracture population-based study., Patient Selection Criteria: All adult patients with hip fractures (OTA/AO 31A and 31B) were included. Patients with pathological or periprosthetic hip fractures were excluded., Outcome Measures and Comparisons: Patients were categorized according to the type of management (operative vs. nonoperative) and type of fracture (nondisplaced vs. other). Patient and fracture characteristics associated with nonoperative management (NOM) were analyzed., Results: A total of 94,930 patients with hip fracture were included. Of these, 3.2% were treated nonoperatively. Patients receiving NOM were older [86 years (interquartile range, 79-91 years) vs. 81 years (interquartile range, 72-87 years); P < 0.001], more frequently institutionalized (42.4% vs. 17.6%), and were more dependent in activities of daily living (22.2% vs. 55.0%). Various clinical characteristics, including dementia [odds ratio (OR) 1.31 (95% confidence interval, CI, 1.18-1.45) P < 0.001], no functional mobility [OR 4.39 (95% CI, 3.14-3.68) P < 0.001], and activities of daily living (ADL) measured as KATZ-6-ADL [OR 1.17 (95% CI, 1.14-1.20) P < 0.001] were independently associated with NOM. Seven-day mortality was 37.6%, and 30-day mortality was 57.1% in patients treated nonoperatively., Conclusions: The first step in understanding patients who potentially benefit from NOM is evaluating the current standard of care. This study provides insight into the current hip fracture population treated nonoperatively. These patients are older, have higher percentage of dementia, more dependent, and show higher short-term mortality rates., Level of Evidence: Therapeutic Level III.

Objective: To develop and validate a prediction model for in-hospital mortality in patients with hip fracture 85 years of age or older undergoing surgery., Design: A multicenter prospective cohort study., Setting: Six Dutch trauma centers, level 2 and 3., Participants: Patients with hip fracture 85 years of age or older undergoing surgery., Intervention: Hip fracture surgery., Main Outcome Measurements: In-hospital mortality., Results: The development cohort consisted of 1014 patients. In-hospital mortality was 4%. Age, male sex, American Society of Anesthesiologists classification, and hemoglobin levels at presentation were independent predictors of in-hospital mortality. The bootstrap adjusted performance showed good discrimination with a c-statistic of 0.77., Conclusion: Age, male sex, higher American Society of Anesthesiologists classification, and lower hemoglobin levels at presentation are robust independent predictors of in-hospital mortality in patients with geriatric hip fracture and were incorporated in a simple prediction model with good accuracy and no lack of fit., Level of Evidence: Prognostic Level II.

Objectives: This study evaluated whether patients with a left-sided femoral neck fracture (FNF) treated with a sliding hip screw (SHS) had a higher implant failure rate than patients treated for a right-sided FNF. This was performed to determine the clinical relevance of the clockwise rotational torque of the femoral neck lag screw in a SHS, in relation to the rotational stability of left and right-sided FNFs after fixation., Methods: Data were derived from the FAITH trial and Dutch Hip Fracture Audit (DHFA). Patients with a FNF, aged ≥50, treated with a SHS, with at least 3-month follow-up data available, were included. Implant failure was analyzed in a multivariable logistic regression model adjusted for age, sex, fracture displacement, prefracture living setting and functional mobility, and American Society for Anesthesiologists Class., Results: One thousand seven hundred fifty patients were included, of which 944 (53.9%) had a left-sided and 806 (46.1%) a right-sided FNF. Implant failure occurred in 60 cases (3.4%), of which 31 were left-sided and 29 right-sided. No association between fracture side and implant failure was found [odds ratio (OR) for left vs. right 0.89, 95% confidence interval (CI) 0.52-1.52]. Female sex (OR 3.02, CI: 1.62-6.10), using a mobility aid (OR 2.02, CI 1.01-3.96) and a displaced fracture (OR 2.51, CI: 1.44-4.42), were associated with implant failure., Conclusions: This study could not substantiate the hypothesis that the biomechanics of the clockwise screw rotation of the SHS contributes to an increased risk of implant failure in left-sided FNFs compared with right-sided fractures., Level of Evidence: Therapeutic Level II.See Instructions for Authors for a complete description of levels of evidence.
