An innovative treatment is described for unstable total hip arthroplasty that uses a large inside diameter acetabular cup and a bipolar femoral head sized to approximate the diameter of the normal hip. Eight consecutive patients with recurrent prosthetic dislocations were treated with this tripolar hip. Joint stability was achieved in all patients, who have an average of 4.2-years' followup (range, 2.6-6.3 years).
本文描述了一种用于不稳定全髋关节置换术的创新治疗方法，该方法使用大内径髋臼杯和尺寸接近正常髋关节直径的双极股骨头。连续8例人工关节反复脱位的患者接受了这种三极髋关节治疗。所有患者均实现了关节稳定，平均随访4.2年（范围2.6 - 6.3年）。
