Between 1995 and 2003, 129 cemented primary THAs were performed using full acetabular impaction grafting to reconstruct acetabular deficiencies. These were classified as cavitary in 74 and segmental in 55 hips. Eighty-one patients were reviewed at mean 9.1 (6.2-14.3) years post-operatively. There were seven acetabular component revisions due to aseptic loosening, and a further 11 cases that had migrated >5mm or tilted >5° on radiological review - ten of which reported no symptoms. Kaplan-Meier analysis of revisions for aseptic loosening demonstrates 100% survival at nine years for cavitary defects compared to 82.6% for segmental defects. Our results suggest that the medium-term survival of this technique is excellent when used for purely cavitary defects but less predictable when used with large rim meshes in segmental defects.
1995 年至 2003 年间，我们采用全髋臼打压植骨技术治疗 129 例初次髋关节置换术患者的髋臼骨缺损，其中 74 例为空洞型，55 例为节段型。术后平均 9.1 年（6.2-14.3 年）对 81 例患者进行了随访。因无菌性松动而行髋臼翻修术 7 例，另外有 11 例出现>5mm 的移位或>5°的倾斜，其中 10 例报告无症状。采用 Kaplan-Meier 分析法对无菌性松动进行翻修，结果显示空洞型缺损的 9 年生存率为 100%，而节段型缺损的生存率为 82.6%。我们的结果表明，对于单纯空洞型缺损，该技术的中期生存率非常高，但对于节段型缺损中存在大的边缘网孔时，其生存率则较难预测。
