Abstract
Objectives: This retrospective observational cohort study compared the radiologic outcomes and mechanical complications associated with four different Proximal Femoral Nail (PFN) designs in patients undergoing extracapsular hip fracture surgery. Patients and Methods: We evaluated 220 patients treated for extracapsular hip fractures with different PFN designs from January 1, 2017, to January 1, 2023. Patient demographics, comorbidities, anesthesia type, operative details, and postoperative radiographs were reviewed. Results: The double lag screws PFN design demonstrated superior fracture reduction, fewer mechanical complications, and a reduced rate of non-union. Conclusion: PFNs with double lag screws are preferable for achieving better fracture reduction and fewer complications. Further biomechanical studies and prospective randomized trials are warranted to refine these findings.
