Abstract:Objective To investigate the effectiveness of proximal femoral nail anti-rotation (PFNA) combined with cable cerclage fixation in the treatment of unstable subtrochanteric fractures in elderly patients. Methods A retrospective analysis was performed on the clinical data of 16 elderly patients with subtrochanteric fracture of femur treated by open reduction and PFNA combined with cable cerclage fixation in Chenggong Hospital Affiliated to Xiamen University from January 2016 to January 2019. The general condition, operation time, intraoperative blood loss, fracture healing time, functional score, complications of the patients were analyzed. Results All patients were operated on successfully. The operation time was (130.56±40.87) min, and the amount of intraoperative bleeding was (167.50±76.46) ml. All patients achieved fracture healing during the follow-uPperiod, with an average healing time of (3.94±0.57) months and without broken nails, infection and obvious hiPvarus deformity. Conclusion For the elderly patients with unstable subtrochanteric fracture, PFNA combined with cable cerclage fixation is conducive to the anatomical reduction of fracture and the stability of fixation, with fewer postoperative complications and satisfactory clinical effect.
