We analyzed the preoperative and perioperative data on sixty-nine consecutive complex total hip replacements performed in fifty-seven patients using miniature or microminiature custom-made femoral components. The patients' average age was 45.7 years. The preoperative diagnosis was congenital dysplasia or dislocation of the hip in 72 per cent of the hips. Acetabular bone grafts were required in thirty-seven of the sixty-nine hips. Operative complications occurred in thirteen (19 per cent) and postoperative dislocation occurred in eleven (16 per cent) of the sixty-nine hips. Fifty-five hips in forty-seven patients were followed for a minimum of two years, the average follow-up being 4.8 years and the longest, 9.8 years. All acetabular grafts united. Loosening of one or both prosthetic components occurred in ten (18 per cent) of the fifty-five hips (twelve of the 110 components became loose). There were no instances of a stem bending or fracturing, despite the small size of the femoral components. Eight hips (14.5 per cent) had undergone revision, six for painful loose components and two for recurrent dislocation. For the forty-seven hips that were not revised, the average Harris hip score rose from 43 points preoperatively to 80 points postoperatively.
我们分析了57例患者连续接受的69例复杂全髋关节置换手术的术前和围手术期数据，这些手术使用了定制的微型或超微型股骨假体。患者的平均年龄为45.7岁。72%的髋关节术前诊断为先天性髋关节发育不良或脱位。69例髋关节中有37例需要进行髋臼植骨。69例髋关节中，13例（19%）发生手术并发症，11例（16%）发生术后脱位。47例患者的55例髋关节至少随访了两年，平均随访时间为4.8年，最长为9.8年。所有髋臼植骨均愈合。55例髋关节中有10例（18%）发生一个或两个假体组件松动（110个组件中有12个松动）。尽管股骨假体尺寸小，但没有发生柄弯曲或骨折的情况。8例髋关节（14.5%）进行了翻修，6例是因为假体组件疼痛性松动，2例是因为复发性脱位。对于未进行翻修的47例髋关节，Harris髋关节平均评分从术前的43分提高到术后的80分。
