全髋关节置换术后并发假体周围骨折相关因素分析

目的 探讨全髋关节置换术后并发假体周围骨折的相关危险因素.方法 选自某院收入的全髋关节置换术患者403例及髋关节翻修患者45例,患者术后根据并发假体周围骨折情况分为骨折组及对照组,记录患者性别、年龄、外伤史、骨质疏松、髋部感染史、假体类型、假体固定方式及髋关节翻修史等情况,计算各因素与假体周围骨折发生的相关性.结果 有外伤史、骨质疏松患者术后假体周围骨折发生率显著高于无外伤史、无骨质疏松患者,结果对比差异有统计学意义(P＜0.05).骨水泥固定假体周围骨折发生率显著高于非骨水泥固定假体(P＜0.05).骨水泥柄发病率低于非骨水泥远端固定柄及非骨水泥近端固定柄(P＜0.05).有髋关节翻修史患者假体周围骨折发生率显著高于无髋关节翻修史患者(P＜0.05).结论 假体周围骨折发生率为5.8％,外伤史、骨质疏松、骨水泥柄、有髋关节翻修史以及骨水泥固定是假体周围骨折的危险因素.

Analysis on relevant factors of around prosthesis fracture after total hip replacement

OBJECTIVE To investigate the relevant factors of around prosthesis fracture after total hip replacement.METHODS 403 total hip arthroplasty patients and 45 revision hip arthroplasty patients were divided into the fracture group and control group according to postoperative periprosthetic fractures,recorded the gender,age,history of trauma,osteoporosis,hip infection history,type of prosthesis,the prosthesis fixation and hip revision history and so on to calculate the correlation of each factor of periprosthetic fractures.RESULTS The incidence rate of around prosthesis fracture in the patients with injury history and osteoporosis was significantly higher than no injury history,no osteoporosis patients,the results had significant differences,P﹤0.05.The incidence rate of around prosthesis fracture in bone cement fixed prosthesis fracture was significantly higher than no bone cement fixed,the results had significant differences,P﹤0.05.The incidence rate of around prosthesis fracture in bone cement handle patients was significantly lower than no bone cement handle patients,P﹤0.05.The incidence rate in patients with pevision hip bone cement history was significantly higher than no revision hip bone cement history patients,the results had statistically significant differences,P﹤0.05.CONCLUSION Prosthesis fracture around rate is 5.8%,and injury history,osteoporosis,bone cement handle,revision hip bone cement history and fixed prosthesis fracture are risk factors for around prosthesis fracture.
