Functional Outcome of Proximal Femoral Nail Antirotation (Pfna) in Proximal Femur Fracture

Background: The Proximal Femoral Nail Antirotation (PFNA) has become a cornerstone in managing proximal femur fractures, offering varied outcomes across different studies. The technique's success, particularly in achieving acceptable reduction, stable fixation, and minimizing complications, significantly hinges on the precise understanding and execution of the implant's entry point. Objective: This study aimed to evaluate the effectiveness of PFNA in treating proximal femur fractures within a tertiary care setting, focusing on patient outcomes post-surgery. Methods: The study enrolled patients aged 18-60 years, of any gender, presenting with proximal femur fractures reported within two weeks of the injury. All participants underwent PFNA within three days of admission for definitive fracture fixation. The Harris Hip Score was utilized to assess functional outcomes at final follow-up, categorizing results into excellent, good, fair, and poor. Results: Among the 125 patients, the mean age was 50.63 ± 8.36 years, comprising 55 (44%) males and 70 (56%) females. Functional outcomes were predominantly positive, with 47 (37.6%) achieving excellent, 21 (16.8%) good, 16 (12.8%) fair, and 14 (11.2%) poor outcomes. Statistical analysis revealed significant correlations between functional outcomes and several factors: age (p<0.001), gender (p<0.001), Body Mass Index (BMI) (p<0.001), comorbidities (p<0.001), fracture type (p<0.001), and injury mechanism (p<0.001). Conclusion: The majority of patients treated with PFNA for proximal femur fractures experienced excellent functional outcomes, underscoring the procedure's effectiveness within the study's demographic. The significant associations between outcomes and patient-specific factors highlight the need for tailored surgical approaches.
