Functional Outcome and Associated Factors Among Patients Aged ≥14 Years with Subtrochanteric Femur Fractures Treated with Surgical Implant Generation Network (SIGN) Intramedullary Nailing Device: A Two-Center Cross-Sectional Study.

Abstract

Subtrochanteric femur fractures are severe injuries resulting from high-energy trauma or low-energy falls in older adults. Surgical method, patient factors, and rehabilitation influence functional outcomes. Although the proximal femoral nail is the gold standard, its use is limited in low- and middle-income countries due to cost and the requirement for radiolucent tables and fluoroscopy. The SIGN nail provides an affordable, fluoroscopy-free alternative, but evidence regarding comparable functional outcomes remains limited
