Abstract

The purpose of this paper was to evaluate the results of acetabular revisions with the use of an oblong revision cup that is designed with its longitudinal diameter elongated relative to its transverse diameter. Between 1996 and 2001, 62 hips in 60 patients underwent an acetabular revision with the insertion of a LOR acetabular component. Seven hips were lost to follow-up or the patients died; the remaining 55 hips (53 patients) remained in follow-up for an average of 7.2 years (range: 5.0-10.1 years). One socket was revised for aseptic loosening, and another was operated on for a late polyethylene liner dissociation. The average Harris hip score (HHS) improved from 34 to 79. Results were rated as excellent in 16 hips, good in 28, fair in six and poor in three. Radiographic analysis demonstrated an improvement in the average vertical displacement of the hip centre: 49 hips had a well-fixed, bone-ingrown cup and four had a stable fibrous union. For large superolateral acetabular bone deficiencies, this implant facilitated a complex reconstruction without the need for bulk structural acetabular bone grafts, provided good clinical results and showed satisfactory stability at the midterm follow-up.

摘要

本文的目的是评估使用一种椭圆形翻修髋臼杯的髋臼翻修结果,该髋臼杯设计为其纵向直径相对于横向直径拉长。1996年至2001年期间,60例患者的62髋接受了髋臼翻修并植入了LOR髋臼组件。7髋失访或患者死亡;其余55髋(53例患者)接受了平均7.2年(范围:5.0 - 10.1年)的随访。1例髋臼因无菌性松动进行了翻修,另1例因聚乙烯内衬晚期分离接受了手术。Harris髋关节评分(HHS)平均从34分提高到79分。结果评为优的有16髋,良的有28髋,可的有6髋,差的有3髋。影像学分析显示髋关节中心平均垂直位移有所改善:49髋有固定良好、骨长入的髋臼杯,4髋有稳定的纤维性骨愈合。对于髋臼上外侧大的骨缺损,该植入物有助于进行复杂的重建,无需大块结构性髋臼骨移植,提供了良好的临床结果,并在中期随访时显示出令人满意的稳定性。
