Aim: The aim of our study is to analyze the functional outcome of unstable intertrochanteric fractures managed with Proximal Femoral nailing.

Patients and Methods: Twenty four patients with unstable intertrochanteric fractures were selected for our prospective study. All were treated with fixation with Proximal femoral nails. The functional outcome of these patients were analyzed using Harris hip score.

Results: At three months follow up 45% of patients had good to excellent results which at six months improved to 91%. In all patients fracture united by six months. We had shortening in six patients, varus collapse in three patients and implant failure in one patient.

Conclusion: Unstable intertrochanteric fractures require reduction and fixation with an intramedullary load bearing implant which ensures early return to preinjury activity which is important especially in the elderly people. Proximal femoral nail offers the solution with less morbidity.
