      【摘要】 目的 探讨桥接组合式内固定系统在人工髋关节置换术后股骨假体周围骨折中的应用效果。方法 回顾性分析 2018年 6月至 2019年 12月在广州市番禺区中医院应用桥接组合式内固定系统治疗人工髋关节置换术后股骨假体周围骨折(Vancouver B1和C型)的11例患者的临床诊治资料，观察患者骨折愈合时间、骨折愈合后髋关节功能评分(Harris评分)、患肢的短缩情况、骨折愈合后行走情况以及并发症发生情况。结果 11例患者的平均随访时间为(6.8±2.1)个月，术口均甲级愈合；所有患者骨折均愈合，平均骨折愈合时间(4.7±1.6)个月，骨折愈合后的髋关节Harris评分平均(80.9±7.7)分；骨折愈合后患肢长度较对侧肢体平均短缩约(0.78±0.33) cm；骨折愈合后7例患者可在无保护下负重行走，4例需依靠手杖或助行器辅助行走；术后未发现明显深静脉血栓、骨折畸形愈合、内固定物失效或假体松动。结论 应用桥接组合式内固定系统治疗人工髋关节置换术后股骨假体周围骨折效果理想，内固定物稳定可靠，是一种理想的选择。

【Abstract】 Objective To explore the clinical effect of bridge combined internal fixation system in the treat-ment of periprosthetic femoral fracture after hip arthroplasty. Methods A retrospective analysis was performed on theclinical data of 11 cases of periprosthetic femoral fractures after hip arthroplasty (Vancouver type B1 and C) treated bythe bridge combined internal fixation system in Guangzhou Panyu District Hospital of Traditional Chinese Medicinefrom June 2018 to December 2019. The time of fracture healing, Harris scores of hip joint after fracture healing, limbshortening, situation of walk after fracture healing, and complications were observed from clinical effects, image dataand follow-up information. Results The mean follow-up time was (6.8±2.1) months of all the 11 cases; the wound ofall cases showed grade A. All the 11 cases had fracture healing, and the mean healing time was (4.7±1.6) months; themean Harris score of hip joint after fracture healing was (80.9±7.7) points; the limb shortening after fracture healing wasshorter than another limb by about (0.78±0.33) cm; among the 11 cases, 7 cases could walk without safeguard, the otherscould walk by cane or walking aid. There were no postoperative complications such as DVT, fracture malunion, internalfixation loosening or prosthesis loosening. Conclusion The effect of bridge combined internal fixation system is idealfor treating periprosthetic femoral fracture after hip arthroplasty, and the internal fixation system is stable and reliable.
