股骨近端髓内钉InterTan治疗老年粉碎性。股骨转子间骨折疗效观察

目的评估InterTan治疗老年粉碎性股骨转子间骨折的临床疗效。方法采用InterTan治疗老年粉碎性股骨转子间骨折30例，对患者术中情况、术后Harris髋关节评分、骨折愈合时间、术后并发症等情况进行评估。结果30例患者中除2例失访，28例患者术后获平均6m随访，骨折均获愈合，愈合时间2～6m，平均愈合时间为（2．6±0．8）m。术后Harris髋关节评分评定结果：优10例，良14例，中3例，差1例，优良率为85．7％，未出现股骨颈颈部短缩，髋内翻，内固定断裂等并发症。结论股骨近端髓内钉INTERTAN是治疗老年粉碎性股骨转子间骨折较好的方法，其骨愈合率高，并发症少。

Clinical outcomes of proximal femur intramedullary nails oflnterTan in the elderly patients with femoral intertro- chanteric comminuted fractures

Objective To estimate the clinical outcomes of proximal femur intramedullary nails of InterTan in the elderly patients with femoral intertrochanteric comminuted fractures. Methods 30 elderly patients with femoral intertrochanteric comminuted fractures were treated with InterTan nails. Their surgical data, Harris hip score, union time and complications were retrospectively analyzed. Results Among the 30 cases, 28 patients were followed up except 2 cases 6 months after the treatment. The healing time of fractures was 2 - 6 months, average （2.6±0.8） months. Postoperative Harris hip score evaluation results： 10 patients had excellent results, 14 good, 3 medium and 1 poor. The excellent and good rate was 85.7%. No collapse of the neck, no coxa vara, or no implant failure was observed. Conclusion The proximal femur intramedullary nails of InterTan is the better clinical treatment for elderly patients with femoral intertrochanteric comminuted fractures with high union rate and rare complications.
