We report the results of 24 acetabular reconstructions in which cemented polyethylene cups and tamped corticocancellous allografts were used for severe acetabular bone deficiency. Eleven hips had type-II (cavitary) bone deficiency and 13 had type-III (combined) defects. At a mean follow-up of 5.8 years, two components had migrated more than 5 mm and had accompanying radiolucent zones of more than 2 mm width. A radiolucency 5 mm wide was also seen in zone III of an acetabular implant which had not migrated. None of the patients had required revision because of loosening or infection.
我们报告了24例髋臼重建的结果，其中使用骨水泥固定的聚乙烯杯和夯实的皮质松质骨同种异体骨治疗严重髋臼骨缺损。11髋为II型（空洞性）骨缺损，13髋为III型（复合型）缺损。平均随访5.8年时，有2个假体组件移位超过5mm，伴有宽度超过2mm的透亮区。在一个未移位的髋臼植入物的III区也可见宽5mm的透亮区。没有患者因松动或感染而需要翻修。
