摘 要: | 目的:比较陶对陶(ceramic-on-ceramic,COC)与陶对聚乙烯假体(ceramic-on-polyeth-ylene,COP)在全髋关节置换术中应用的可靠性和耐用性。方法对77例接受初次全髋关节置换的患者进行回顾性研究,比较 COC 与 COP 两种不同假体术后髋关节功能及并发症。结果COC组与 COP 组术后髋关节 Harris 评分分别为92.6±5.1和91.3±4.2,差异无统计学意义(P >0.05);两者在翻修、脱位、陶瓷破碎、异响、松动、骨溶解、深部感染、异化骨化发生率的比较,差异无统计学意义(P >0.05)。结论COC 与 COP 假体均能获得较好的临床疗效,两者术后在髋关节功能及并发症方面疗效相当。

Abstract: | Objective To compare the reliability and durability of ceramic-on-ceramic(COC)and ceramic-on-polyethylene(COP)bearing surfaces in total hip arthroplasty(THA).Methods A retrospec-tive study was performed on 77 patients who received primary THA.Hip joint functions and complications between the two groups were observed for comparison.Results Postoperative Hip Harris scores(HHS) were(92.6 ±5.1)and(91.3 ±4.2)in the COC group and COP group,respectively.The difference was not significant(P 〉0.05 ).There were no significant differences in revision,dislocation,ceramic fracture, squeaking,loosening,osteolysis,deep infection and heterotopic ossification between the two groups(P 〉0.05).Conclusion Both of COC and COP bearing surfaces can get excellent therapeutic effects in THA. There are similar results on postoperative hip function and complications between the two kinds of prosthe-ses. |
