骨水泥型假体与生物型假体在髋关节发育不良患者中的疗效对比

摘要

Objective To compare the effect of cemented prosthesis and biological prosthesis in the treatment of patients with development dysplasia hip (DDH).Methods 80 patients with DDH who would undergo total hip arthroplasty were randomly divided into research group (40 cases) and control group (40 cases). The total hip arthroplasty of research group was conducted with biological prosthesis while that of control group was conducted with cemented prosthesis. Then the safety and effectiveness of research group were compared with those of control group from the aspects of operation time, bleeding quantity, survival rate of prosthesis and Harris score.Results The average operation time of research group was (98.7±18.9) min while that of control group was (140.7±51.9) min. The average bleeding quantity of research group was (280.0±60) mL while that of control group was (360.0±100) mL. The survival rate of prosthesis of research group was 95% while that of control group was 82.5%. The Harris score calculated at the last follow-up of prosthesis of research group was (91.7±9.8) while that of control group was (82.9±11.3). There were signiifcant differences between research group and control group in operation time, bleeding quantity, survival rate of prosthesis and Harris score.Conclusion Total hip arthroplasty conducted with biological prosthesis which owns advantages such as high stability and ideal mid-term and long-term curative effect should be promoted in the treatment of patients with DDH.%目的：对比骨水泥型与生物型假体在髋关节发育不良患者中的疗效。方法将行全髋关节置换术的髋关节发育不良患者80例随机分为两组，研究组40例采用生物型假体进行置换术，对照组40例采用骨水泥型假体进行置换术。从手术时间、出血量、假体存活率、Harris评分等方面评价两组手术的安全性及疗效。结果研究组手术时间为（98.7±18.9）min，对照组为（140.7±51.9）min，差异具有统计学意义（P<0.05）。研究组出血量为（280.0±60）mL，对照组为（360.0±100）mL，差异具有统计学意义（P<0.05）。研究组假体存活率为95%，对照组为82.5%，差异具有统计学意义（P<0.05）。末次随访时研究组平均Harris评分为（91.7±9.8）分，对照组为（82.9±11.3）分，差异具有统计学意义（P<0.05）。结论对于髋关节发育不良患者，采用生物型假体行全髋关节置换术具有稳定性高、中远期疗效满意的优点，值得临床推广。
