The Functional Outcome of Patients Treated with Proximal Femoral Nail (Pfn) for Sub Trochanteric Femur Fracture in Ayyub Teaching Hospital, Abbottabad

Sub-trochanteric femur fractures are challenging for orthopedic surgeons to fix owing to their location and associated consequences. Different intramedullary and extra-medullary implant stabilization techniques have been explored with varying degrees of effectiveness. Objective: To assess the functional outcomes of proximal femoral nail in patients treated for sub-trochanteric femur fracture. Methods: This cross-sectional study investigated 28 patients of sub trochanteric femur fracture treated with proximal femoral nail in Orthopedic Unit of Ayub Teaching Hospital, Abbottabad from January 2021 to March 2024. Patients aged≥20 years who suffered from sub-trochanteric femur fracture and fit for surgery were included. All the patients were immobilized before surgery. Skin traction was applied and prepared for surgery. Postoperative outcome was assessed using the Harris hip score. Results: The overall mean age was 56 ± 10.8 years. Out of 28 cases, there were 18 (64.3%) male and 12 (35.7%) female. The overall mean of hospital duration was 14 ± 4.6 days. The majority of patients were 41-60 years old. Postoperative independence of ambulation was assessed in each patient after three, five, and six months. After 5 months, only two patients were unable to move around unassisted. Based on the Harris Hip Score, the incidence of exceptional, good, and fair outcomes was 6 (21.4%), 5 (17.9%), and 17 (60.7%) respectively. Conclusion: It was concluded that sub-trochanteric femur fractures can be treated with a proximal femoral implant, which offers advantages in terms of increased stability, quick disposition and minimal exposure.
