Abstract

UNLABELLED

Hydroxyapatite (HA) is commonly used on femoral stems to assist in osseous integration but there is limited evidence of the benefit it provides. We report a prospective comparison of 117 and 102 patients receiving either porous or HA coated sleeves respectively. Patients were evaluated at mean of 12.5 years in the porous and 13.7 years in the HA groups. The mean Harris Hip Score was 94.7 and 94.5 in the porous and HA groups respectively. One porous and 2 HA stems required revision. This study demonstrates that there is no long-term advantage to using an HA coating on the sleeve of this modular stem and confirms excellent long-term results for the SROM stem in a primary arthroplasty setting.

LEVEL OF EVIDENCE

II (prospective cohort study).

羟基磷灰石（HA）常用于股骨柄以辅助骨整合，但关于其益处的证据有限。我们报告了分别接受多孔或HA涂层套筒的117例和102例患者的前瞻性比较。多孔组患者平均随访12.5年，HA组患者平均随访13.7年。多孔组和HA组的平均Harris髋关节评分分别为94.7和94.5。1例多孔柄和2例HA柄需要翻修。本研究表明，在这种模块化柄的套筒上使用HA涂层没有长期优势，并证实了SROM柄在初次关节成形术中的优异长期效果。
