摘要(Abstract)：

[目的]评估陶瓷对陶瓷全髋关节置换术(THA)治疗髋关节终末期疾病中长期临床疗效和影像学结果,重点观察磨损、骨溶解、陶瓷碎裂发生率。[方法]2001年5月~2005年5月,共142例(148髋)在本院行陶瓷对陶瓷THA治疗。平均年龄57.2岁(23~81岁),平均随访8.8年(7~12年)。术前诊断:股骨头缺血性坏死77髋(52%)、髋关节退行性骨性关节炎36髋(24.3%)、股骨颈骨折18髋(12.2%)、类风湿关节炎15髋(10.1%)及化脓性髋关节继发关节退变2髋(1.4%)。评估患者术后临床功能(Harris评分)、术后大腿及腹股沟疼痛发生率。影像学评估重点观察是否有磨损、假体周围骨溶解及陶瓷碎裂。[结果]平均Harris评分由术前的58.3分(10~73分)提高到末次随访的92.5分(79~100分)。在末次随访时,有4髋(2.7%)出现腹股沟部疼痛,6髋(4.2%)出现大腿疼痛,这些患者均未发现股骨柄假体松动。共29髋观察到假体周围有非连续性透亮线,其中股骨侧25髋(16.9%),髋臼侧4髋(2.7%)。观察到膜内成骨在股骨侧有95髋(64.2%),在髋臼侧有88髋(59.5%)。股骨侧和髋臼侧均未观察到骨溶解。有2髋(1.4%)出现髋臼杯倾斜角的改变,2髋(1.4%)髋关节脱位,1髋(0.7%)陶瓷头碎裂,1髋(0.7%)出现异响。Kaplan-Meier生存率分析,假体平均术后8.8年存留率为98.1%。[结论]陶瓷对陶瓷THA是治疗髋关节终末期疾病的有效方法,可以获得满意的中长期临床疗效以及较高的假体存留率。
