Trochanteric hip fractures treated surgically-outcome in a ten-year cohort of 46,121 patients from the Swedish National Hip Fracture Registry.

Objectives: To compare postoperative mortality regarding 2 techniques in the treatment of trochanteric hip fractures (THFs). Design: Retrospective cohort study. Setting: National databases. Patients: All consecutive surgically treated THF cases between 2008 and 2017 were included. Pathological fractures or patients younger than 60 years were excluded. Intervention: Patients were grouped based on the surgical technique: sliding hip screw (SHS) or intramedullary (IM) nail. This data set was cross-referenced with a National Board of Health and Welfare's patient registry and a Cause of Death registry. Main outcome measurements: Mortality, comorbidities, and length of stay (LOS). Results: Forty-six thousand one hundred twenty-one cases were included. Twenty-five thousand eight hundred seventy-seven patients received a SHS, and 20,244 received an IM nail. Patients in the IM group were more often female (71.8% vs. 69.2%, Conclusions: Based on 10 years of data including 46,121 patients with THF managed with SHS or IM nail, no difference was observed in mortality up to 1 year postoperatively, when comparing surgical technique. LOS was shorter for the IM nail group.
