股骨近端抗旋髓内钉内固定治疗老年人不稳定股骨粗隆间骨折的疗效分析

摘要

Objective To retrospectively analyze the results of treatment with Asian proximal femoral nail anti rotation intramedullary nail (PFNA Ⅱ) in senile patients with unstable intertrochanteric femoral fractures. Methods 1 06 cases of unstable intertrochanteric femoral fracture with internal fixation of PFNAⅡ were analyzed retrospectively,and the treatment effect was observed.Results 1 06 cases were followed -up(mean 1 3.5 months, ranged 1 0 -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 1 06mL.The hip functions were analyzed using Harrison score.And found 80 excellent cases,1 4 good cases,1 2 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.%目的：探讨亚洲型股骨近端抗旋髓内钉（PFNAⅡ）内固定治疗老年人不稳定股骨粗隆间骨折的疗效。方法回顾性分析使用 PFNAⅡ内固定治疗的老年人不稳定股骨粗隆间骨折106例的临床资料，观察其疗效。结果106例均获得随访，随访时间10～22个月，平均13．5个月，骨折全部愈合，平均愈合时间3．8个月。手术时间平均48 min，手术中出血量平均106 mL。根据 Harris 髋关节功能评分，优80例，良14例，可12例，总优良率88．7％。结论对于老年不稳定股骨粗隆间骨折的患者，PFNAⅡ具有髓内固定的生物力学优势，创伤小，手术时间短，内固定可靠，可早期功能练习，并发症发生率低，功能恢复效果显著，是优先的治疗选择。
