Radiological and functional outcome of PFN A2 in treatment of intertrochanteric fractures in elderly patients

Introduction: Intertrochanteric fracture is one of the most common fracture seen in elderly age group. Intramedullary fixation achieves stable fixation. This study was done to find out outcomes with PFNA2, with an objective of finding significance of various radiological parameters. Methods: Forty-three patients were included who underwent closed reduction and PFNA2 fixation. They were followed up at 1month, 3months, 6months and 1 year postoperatively and tip apex distance, Cleveland index, parkers ratio, nail protrusion height, and neck shaft angle were calculated. Statistical correlation of each parameter with complications such as helical blade cut out and back out was derived. Results: Tip apex distance and Cleveland index was found to influence the position of screw and thereby the final outcome. No statistical correlation was derived between Parkers ratio, neck shaft angle and nail protrusion height with the complications. Functional outcome as calculated by Harris hip score was found to be satisfactory in most of the patients. There was only negligible mean loss of functional outcome postoperatively as calculated with parkers mobility score Conclusion: PFNA2 confirms to be stable fixation for both stable and unstable intertrochanteric fracture with fewer complication and good functional outcome in short period of time.
