摘要
目的:回顾性研究陶瓷对陶瓷全髋关节假体行人工全髋关节置换术治疗成人髋关节疾病的早期疗效。方法:2007年10月至2010年9月对符合标准的42例患者(44髋)进行了全髋关节置换术。假体类型为DePuy公司Pinnacle陶瓷对陶瓷全髋关节假体(CoC组)和Duraloc金属对聚乙烯全髋关节假体(MoP组),均为非骨水泥型人工关节。其中CoC组20例22髋,男12例,女8例,年龄21~49岁;MoP组22例22髋,男13例,女9例,年龄42~55岁。手术方法采用后外侧入路,术后给予常规抗凝治疗及相应功能锻炼。术后患者进行定期临床与放射学随访,随访时间至少6个月。测量手术前及术后6个月时两组患者关节活动度,并按Harris评分对髋关节功能进行评价。结果:所有患者无脱位、松动、感染及下肢深静脉血栓等并发症发生。两组Harris评分及髋关节活动度术前术后比较差异无统计学意义(P>0.05)。结论:陶瓷对陶瓷全髋在改善患者症状及髋关节活动度方面与传统的金属对聚乙烯关节疗效相当,其优点和长期疗效还有待进一步观察。因其具有良好的耐磨性,是年轻患者全髋关节置换较为理想的关节界面选择。
Objective:To retrospectively study early therapeutic effects of the ceramics to ceramics prosthesis design in treating hip disease. Methods:From October 2007 to September 2010,42 patients (44 hips) with hip disease underwent replacement of total hip. Hip prosthesis designs included the Pinnacle ceramics to ceramics and the Duraloc metal to polyethylene,produced by DePuy Company,all were non-bone cement type of artificial hip joint. Twenty patients (22 hips) were performed with ceramics to ceramics total hip prosthesis (CoC group,there were 12 males and 8 females,aged from 21 to 49 years) and 22 patients (22 hips) were performed with metal to polyethylene total hip prosthesis (MoP group,there were 13 males and 9 females,aged from 42 to 55 years). All the surgical approachs were posterolateral,and the routine anticoagulation and the corresponding functional exercise were performed after operation. The follow-up time was 6 months at least including clinical and radiographic observation. Measured the motion of joint and evaluated the function of hip joint according to Harris classification. Results:All clinical effects were satisfactory and no dislocation,loosening,infection,deep venous thrombosis and other complications occurred. There was no statistical significance in Harris scoring and the motion of joint between two groups before and after operation (P0.05). Conclusion:The clinical effect of ceramics to ceramics prosthesis design in improving clinical symptoms and the motion of joint is coordinate with metal to polyethylene total hip prosthesis ,however,its advantages and long-term efficacy need further observing. The ceramics to ceramics prosthesis design may be a good choice for the young patients with hip disease because of its good wear resistance.
