The present study aims to evaluate the functional outcomes of the Proximal Femoral Nail Antirotation II in treating unstable intertrochanteric fractures.This 24-month prospective study was conducted on 39 patients with unstable intertrochanteric femur fractures who visited the Orthopaedics outpatient department at Government Medical College & Hospital, Amritsar from August 2020 to July 2023.Results of the present study highlights the significant effectiveness of the Proximal Femoral Nail Anti-Rotation II (PFN-A2) in improving functional outcomes for patients with unstable intertrochanteric femur fractures. The study demonstrated a consistent and statistically significant improvement in the Harris Hip Scores (HHS), with scores rising from 54.20 at 6 weeks to 84.60 at 24 weeks, reflecting substantial functional recovery. These findings align with previous research, further supporting PFN-A2 as a reliable fixation method, particularly for osteoporotic elderly patients, and emphasizing its role in early mobilization and reduced complication rates. The study's results underscore the importance of PFN-A2 in achieving optimal recovery outcomes for unstable intertrochanteric fractures, contributing to the growing body of evidence favoring intramedullary fixation over other treatment options.
