大头金对金全髋关节置换治疗老年人股骨颈骨折近期疗效

摘要

目的 探讨大头金对金全髋关节置换术治疗老年人股骨颈骨折的近期疗效.方法 55例老年股骨颈骨折患者(55髋)中,26髋采用大头金对金全髋关节置换(观察组),29髋采用常规小头金属对聚乙烯全髋关节置换(对照组),比较两组的临床疗效,对并发症进行分析.结果 55例门诊随访12~23(18.3±5.4)个月.术后对照组发生脱位1例2次;观察组无脱位发生.观察组术后6、12周的髋关节活动范围和术后12个月的Harris评分优秀率均优于对照组,差异有统计学意义(P<0.05).结论 大头金对金全髋关节置换术治疗老年股骨颈骨折,具有术后脱位率低、关节活动范围大等优点,近期临床疗效满意.%Objective To discuss the short-term clinical effect of large diameter metal-on-metal total hip arthroplasty ( THA ) in elderly patients with femoral neck fractures. Methods 55 elderly femoral neck fractures patients with 55 hips underwent the operation of THA, 26 hips were performed with large diameter metal-on-metal hip prosthesis ( experimental group ), other 29 hips were performed with conventional diameter metal-on-polyethylene hip prosthesis ( control group ), the clinical effect were compared between the two groups and the complications were analyzed. Results All of the 55 patients were followed up in outpatient for 12 ～23 ( 18. 3 ±5. 4 ) months. In control group, dislocation occurred in 1 case for 2 times while no dislocation happened in experimental group. Compared with control group, the experimental group had better range of motion in 6 and 12 weeks postoperative and higher excellent rate of Harris score 12 months postoperative, there was statistical difference between the two groups( P <0. 05 ). Conclusions Large diameter metal-on-metal THA in treating elderly patients with femoral neck fractures had satisfactory short-term clinical outcome with low rate of postoperative dislocation and good range of motion.
