Several methods of treatment are available for acetabular revision associated with bone loss. Jumbo cups (minimum diameter of 62 mm in women, 66 mm in men, or 10 mm larger than the normal contralateral acetabulum) are often useful for large defects. The purpose of this study is to report a large jumbo cup series with an average 10-year follow-up. A total of 196 jumbo cups in 186 patients with a minimum of 2-year follow-up were available for review. Harris hip score improved from 44 preoperatively to 72 postoperatively. Survivorship was 98% at 4 years and 96% at 16 years. Five revisions and two resection arthroplasties were performed for failure. In conclusion, porous jumbo cup acetabular revision with supplemental screw fixation provides good to excellent intermediate- and long-term outcomes.
对于伴有骨量丢失的髋臼翻修，有几种治疗方法可供选择。超大臼杯（女性最小直径为62毫米，男性为66毫米，或比正常对侧髋臼大10毫米）通常对大的骨缺损有用。本研究的目的是报告一个平均随访10年的大型超大臼杯系列。共有186例患者的196个超大臼杯可供回顾，这些患者至少随访了2年。Harris髋关节评分从术前的44分提高到术后的72分。4年生存率为98%，16年生存率为96%。因失败进行了5次翻修和2次切除关节成形术。总之，采用补充螺钉固定的多孔超大臼杯髋臼翻修术可提供良好至优异的中长期疗效。
