Sub-trochanteric fractures of the femur remains one of the most challenging fractures faced by orthopaedic surgeons. This study was done to analyse the functional outcome of management and complications of sub-trochanteric fractures using long proximal femoral nail.
Materials and Methods: This was a prospective study of 25 patients with sub-trochanteric fractures of femur who were treated with long PFN at a tertiary care center from May 2016 to July 2018. The fractures were classified according to Seinsheimer classification. All patients were assessed functionally by Harris Hip Score.
Results: Average duration of union was 17.08 weeks (range 13 to 32 weeks), union was achieved in 92% cases. Closed reduction was achieved in 68% cases and open reduction was required in 32% cases. Various intraoperative complications were seen in 12% and delayed complications in 26% of cases. Good anatomical results were achieved in 86% of cases and 14% were fair. As per Harris Hip score, excellent results were noted in 28% cases, good in 56% cases and fair in 16% cases.
Conclusion: The long PFN is a reliable implant for subtrochanteric femur fractures, with high rate of bone union and minimal soft tissue damage. Intramedullary fixation has biological and biomechanical advantages, but the surgery is technically demanding.
