Bipolar arthroplasty of the hip was introduced by the first author in 1974. From that time until 1988, this type of arthroplasty has been carried out in 1213 hips at the authors' institution. Included is a group of 760 osteoarthritic hips on which follow-up studies have been done at six months, five years, ten years, and 15 years. Studies of the acetabulum show healthy bone preservation as long as 15 years after surgery. A process of floor reinforcement in certain states has also been identified. The relatively simple operative technique has resulted in few postoperative complications. Clinical results as long as 15 years postsurgery compare favorably with two-piece replacement techniques.
1974年，第一作者引入了双极人工髋关节置换术。从那时起到1988年，作者所在机构已对1213例髋关节进行了这种类型的关节置换术。其中包括760例骨关节炎髋关节，对这些病例在术后6个月、5年、10年和15年进行了随访研究。髋臼研究显示，术后长达15年骨质保持健康。还确定了某些状态下的髋臼底强化过程。相对简单的手术技术导致术后并发症较少。术后长达15年的临床结果与两件式置换技术相比具有优势。
