Abstract: Background: Subtrochanteric fractures of the femur remain some of the most challenging fractures facing orthopaedic surgeons. Most of the fractures in the elderly results from trivial fall from standing or walking, while in the younger age group it’s mainly due to road traffic accidents. Closed management of these subtrochanteric fractures thus poses difficulties in obtaining and maintaining a reduction, making operative management the preferred treatment. Therefore, this has led to the development of intramedullary devices in the management of subtrochanteric fractures.
Objective: To analyze functional outcome of Subtrochanteric fractures by proximal femoral nail antirotation A2 (PFN-A2).
Materials and Methods: A prospective study with 20 adult patients with subtrochanteric fractures according to Seinsheimer’s classification were treated with proximal femoral nail antirotation-2 (PFN-A2) in SSIMS, Davangere from October 2017 and March 2019. All the cases were followed at regular intervals as per our study protocol. The functional outcome were assessed with Modified Harris Hip Score.
Results: In the present study, 20 subtrochanteric fractures underwent surgical fixation with proximal femoral nail antirotation 2 (PFN-A2). According to Modified Harris Hip scores, out of 20 cases, the functional outcome were excellent in 5 cases (25.00%), good in 11 cases (55.00%), fair in 3 cases (15.00%) and poor in 1 case (5.00%).
Conclusion: We conclude that the proximal femoral nail antirotation 2 (PFN-A2) was an ideal and reliable implant for subtrochanteric fractures, leading to high rate of bone union, reducing the chances of implant failure and decreasing the post-operative morbidity by improving the functional quality of life.
