The purpose of the study was to determine whether isolated revision of the acetabular component can be successfully performed without disturbing the femoral stem and to determine the fate of the unrevised femoral stem following revision. Fifty-seven hips in 55 patients underwent isolated acetabular revision without removal of the femoral component. Thirty-three hips with minimal acetabular deficiency required no bone grafting; the remaining 24 hips were treated by morselized or structural allograft in addition to a new acetabular component. Twenty-two of these 24 hips demonstrated incorporation of the bone graft. A mean follow-up of 5.8 (5-9) years, all femoral and acetabular components were judged to be stable and well fixed.
该研究的目的是确定在不干扰股骨柄的情况下,能否成功地单独进行髋臼部件翻修,并确定翻修后未翻修股骨柄的转归。55例患者的57髋接受了未移除股骨部件的单独髋臼翻修。33髋髋臼缺损最小,无需植骨;其余24髋除植入新的髋臼部件外,还采用了碎骨或结构性同种异体骨移植治疗。这24髋中有22髋显示骨移植已融合。平均随访5.8(5 - 9)年,所有股骨和髋臼部件均被判定稳定且固定良好。
