老年骨质疏松患者生物型与骨水泥型全髋关节置换术临床疗效对比分析

目的:总结分析老年骨质疏松患者应用生物型全髋关节置换术及骨水泥型全髋关节置换术的疗效。方法:2002年3月至2008年4月对94例严重骨质疏松的髋部骨折患者分别根据骨折类型及骨密度测量结果选择生物型及骨水泥型全髋关节置换术,术后随访,进行髋关节功能、疼痛与关节活动度测定及髋部影像学检查,采用Harris评分标准对不同固定方式的临床疗效进行回顾性分析。结果:老年骨质疏松的股骨颈骨折、粗隆间骨折患者经全髋关节置换术,患者术后均进行随访,骨水泥型假体与生物性假体相比的临床疗效存在明显差异(P<0.01)。结论:对于老年骨质疏松患者行全髋关节置换术,骨水泥型术后疗效优于生物型。

Comparative Analysis of Clinical Results of Biotype and Bone Cement-type Total Hip Arthroplasty in Elderly Patients with Osteoporosis

Objective To analyze and summarize the clinical results of biotype and bone cement-type total hip arthroplasty in elderly patients with osteoporosis.Methods From March 2002 to April 2008,for 94 patients with hip fracture caused by severe osteoporosis,according to type of fracture and bone mineral density（BMD） measurement results,biotype or bone cement-type total hip arthroplasty was selected.Patients were followed up,the hip function,pain,motion range were determined,and also the hip imaging was studied.Harris score was used to evaluate the therapeutic effects of different fixation.Results All the elderly patients with femoral fractures or intertrochanteric fractures who underwent total hip arthroplasty were followed up,and the therapeutic effects were different between the biotype and bone cement-type total hip arthroplasty with a significant difference（P0.01）.Conclusion For total hip arthroplasty to the elderly patients with osteoporosis,the curative effect of bone cement-type is better than that of biotype
