Background: Fractures of the proximal femur of the hip are relatively common injuries in adults. Several epidemiological studies show that the incidence of fractures of the proximal femur is increasing. Dissatisfaction with use of a sliding hip screw in unstable fracture patterns led to the development of intramedullary hip screw devices. This design offers potential advantages like more efficient load transfer, decrease tensile strength on the implant, controlled fracture impaction, reduces amount of sliding and therefore limits limb shortening and deformity.

Objectives: study to evaluate the complications related to proximal femur fractures treated with Proximal Femur Nail.

Methods: This is a prospective study of 30 cases of fresh intertrochanteric and subtrochantric fractures admitted to a tertiary care center. Cases were taken according to inclusion and exclusion criteria. Results were evaluated by fracture union on X ray and descriptive statistics were used to analyze the data.

Results: In our series of 30 cases there were 23 males and 7 females, most of the patients were between 41 to 60 years. Mean age of 57.7 years, of cases were admitted due to slip and fall and with predominance of right side. A total of 11 (36.7%) cases had intraoperative complications. Around 6.6% had superficial wound infection as immediate postoperative complication. A total of 7 (23.3%) had delayed complications (delayed union, varus malunion, shortening of more than 1cm, knee joint stiffness).

Conclusion: From this study, we consider that Proximal Femoral Nail as a reliable implant for the treatment of intertrochanteric and subtrochantric fractures. This implant found to have minimal intraoperative complications, immediate post-operative complications and delayed complications in intertrochanteric and subtrochantric fractures. PFN remains the implant of choice in the management of extracapsular proximal femur fractures
