摘　　要：背景：近年来,以Biolox delta 为代表的新一代氧化铝基复合陶瓷（AMC）人工髋关节假体开始应用于临床。目的：观察AMC人工髋关节假体的初期临床效果。方法：2010年1月至2012年9月共收治人工全髋关节置换患者1160例1186髋,AMC组639例657髋,男217例,女422例,年龄15～79岁,平均47.2岁,采用AMC人工髋关节假体;对照组521例529髋,男241例,女280例,年龄20～83岁,平均53.1岁,采用纯氧化铝陶瓷人工髋关节假体。术后3、6、12个月及之后每年1次随访,随访内容为临床观察、影像学检查和髋关节Harris评分。结果：1160例1186髋全部获得随访,随访时间为3～21个月,平均13.3个月。AMC组末次随访的Harris评分为75～100分,平均96.3分;对照组末次随访的Harris评分为75～100分,平均95.3分。结论：AMC人工髋关节假体治疗髋关节疾病的近期疗效满意,但需持续关注假体碎裂的问题。Background： Recently, as the representative of a new generation of Biolox delta, alumina matrix composite ceramic （AMC） artificial hip joint prosthesis behas been used clinically. Objective： To observe the primary clinical result of AMC total hip arthroplasty. Methods： From January 2010 to September 2012, 639 patients （657 hips） were treated by total hip arthroplasty with AMC; and 521 patients （529 hips） treated with pure alumina prostheses served as control group. The follow-up radiographic evalua- tion and clinical Harris score were retrospectively analyzed. Results： All the 1160 cases were followed up for 3-21 months, averaging 13.3 months. Harris score at last follow-up was 75-100 in AMC group, averaging 96.3; and it was 75-100 in the control group, averaging 95.3. Conclusions： The primary clinical result of AMC hip prostheses was satisfactory; however, the broken ceramic liner needs a long-term follow-up.
