摘　　要：[目的]研究不同材料假体对人工全髋关节置换近期临床效果的影响。[方法]选取85例92髋人工全髋关节置换患者,通过X线影像资料,对不同材料髋关节假体对股骨近端、髋臼周围骨质的应力影响进行临床观察。[结果]各组均未发现髋臼及股骨假体松动的临床表现,髋臼及股骨假体周围的骨量无明显应力性骨吸收影像,金属-金属组、陶瓷-陶瓷组未发现有碎屑反应,陶瓷-聚乙烯组、金属-聚乙烯组部分有碎屑反应。[结论]使用不同材料假体组合并不会导致股骨假体、髋臼假体与骨界面应力的显著差别,其远期效果差别除了与假体的制作水平、患者的骨质条件及医生的手术技术等密切相关外,聚乙烯材料产生的磨损碎屑所致的骨溶解应该是最关键因素。[ Objective ] To study the clinical results of the total hip replacement with different materials prosthesis. [Methods] Eighty- five patients （nighty- two hips） undergoing total hip replacement were enrolled in this study. Through X - ray examination, the stress force of different material prosthesis on the proxmial femur and periaccetabular bone was observed. [ Results ] There were no clinical signs of the loose or bone absorption around the prostheses in all patients. Debris reaction was found in the metal- polyethylene group and ceramic -polyethylene group, not found in the metal -metal group and ceramic - ceramic group. [ Conclusion] The stress force between different material prostheses and bone interface was not significantly dif- ferent. Bone osteo]ysis doue to wear of polyethylene prosthesis is the key factor for the long - term outcomes of the total hip replacement. In addition, it is correlated with prosthesis manufacture, bone quanlity and surgical technique.
