N2 - Background: Proximal femoral fractures has been associated with high mortality risk, while little is known about more distal lower extremity fractures. The aim was to report 30- and 365-days mortality in surgically treated lower extremity fractures in individuals above 65 years. Materials and methods: We extracted data from the Danish National Patient Register on all surgically treated lower extremity fracture in the period 1998–2017. The primary outcome was mortality reported by fracture site defined by ICD-10 codes (femur S72*, tibia S82*, foot/ankle S92*S825–8). The secondary outcomes were mortality divided on sex, age groups (5-year span), and comorbidity. This study was conducted using descriptive statistics. Results: We identified 182,013 operatively treated lower extremity fractures of which 73 % occurred in females. The 30-day mortality was 10 % for patients with femoral fractures, 2 % for tibia and 1 % for foot/ankle. The 30-day mortality were similar in femoral fractures regardless of location in the femur (8–11 %). The 365-day mortality was 29 % for femoral fractures, 8 % for tibia and 6 % for foot/ankle. Men with a femoral fracture had higher mortality (15 % at 30 days, 37 % at 356 days) in comparison to women (8.2 % at 30 days, 26 % at 356 days). For the above 85+ year age group, the fracture location was less important for 365-day mortality. Conclusion: There was an observed high risk of mortality in surgically treated femoral fractures. The mortality risks seems to rapidly decline when the fractures are below the knee.
