Displaced right femoral neck fracture7/23/2023 There was an increased risk of mortality for arthroplasty within 30 days, HR 1.3 (95% CI 1.3–1.4), compared with IF but not after 1 and 5 years. Results - We included 19,260 FNF treated with arthroplasty and 10,337 FNF with IF. We calculated hazard ratios (HR) with 95 % confidence intervals (CI) adjusting for relevant confounders. IF and arthroplasty patients were compared with regards to mortality and reoperation up to 5 years postoperatively. ![]() Data on medication, comorbidities, reoperation, and mortality were retrieved from other Danish medical databases. Patients and methods - Hip fracture patients were identified in the Danish Multidisciplinary Hip Fracture Registry during 2005–2015. We assume that, per se, there is no difference in mortality risk between patients with a displaced and an undisplaced FNF. In this population-based cohort study we compare the risk of mortality and reoperation in undisplaced FNF treated with IF and displaced FNF treated with arthroplasty in patients older than 70 years old.
