A prospective study of 119 consecutive primary ceramic total hip arthroplasties (Autophor, Smith & Nephew) was performed. Follow up was 100% at a minimum of 3 years. Six hips were revised during the course of the study (5%). Harris hip scores were 29.0 preoperatively, 78.7 at 6 weeks, and 92.6 at 3.4 years (range: 62 to 100). Ninety-one percent of the 107 surviving hips at follow up had a good or excellent hip score. The clinical results matched those of Mittelmeier. Thigh pain was a frequent finding, but rarely presented a clinical problem. Our incidence of thigh pain may be higher than that of others because no patients were lost to follow up. The ceramic portion of the Autophor Ceramic Hip was well tolerated clinically and radiographically. The femoral component was responsible for 2% to 4% of the revisions, and we have now replaced it with a stem designed for bony stabilization.
对连续119例初次陶瓷全髋关节置换术（Autophor，施乐辉公司）进行了一项前瞻性研究。随访率为100%，最短随访时间为3年。在研究过程中有6例髋关节进行了翻修（5%）。Harris髋关节评分术前为29.0，6周时为78.7，3.4年时为92.6（范围：62至100）。随访时107例存活髋关节中有91%的髋关节评分良好或优秀。临床结果与米特尔迈尔的结果相符。大腿疼痛是常见表现，但很少引起临床问题。我们的大腿疼痛发生率可能高于其他人，因为没有患者失访。Autophor陶瓷髋关节的陶瓷部分在临床和影像学上耐受性良好。股骨部件导致了2%至4%的翻修，我们现在已将其替换为一种旨在实现骨稳定的柄。
