Abstract
Objective To retrospectively analyze the results of treatment with Asian proximal femoral nail anti rotation intramedullary nail(PFNAⅡ) in senile patients with unstable intertrochanteric femoral fractures. Methods 106 cases of unstable intertrochanteric femoral fracture with internal fixation of PFNAⅡ were analyzed retrospectively, and the treatment effect was observed. Results 106 cases were followed-up(mean 13.5 months, ranged 10-22 months). Bone union occurred in all cases, average fracture healing time was 3.8 months.The average operation time was 48 minutes, the average volume of blood loss was 106mL.The hip functions were analyzed using Harrison score.And found 80 excellent cases, 14 good cases, 12 fair cases, with 88.7% of excellent and good rate. Conclusion For the senile patients of unstable intertrochanteric femoral fractures, PFNAⅡ has the biomechanical advantages of intramedullary fixation, small trauma, short operation time, reliable internal fixation, early functional exercise, low incidence of complications, significant functional recovery, and is a preferred treatment option.
