Abstract

The purpose of this study was to evaluate the effects of partial and full weightbearing after cementless total hip arthroplasty over a two year follow-up period. Fifty-nine women and 41 men (average age 61 years) received an uncemented Spotorno stem and were randomised into a full and a partial weightbearing group. No significant difference was found between the groups with regard to the Merle d' Aubigne hip score, VAS pain level, shaft migration or radiographic signs of bony ingrowth. All femoral components seemed radiologically well-fixed and showed bone ingrowth at 24 months. Provided that solid initial fixation is obtained full weightbearing immediately after cementless total hip arthroplasty using a hydroxyapatite-coated Spotorno-type femoral shaft component can be recommended.

摘要

本研究旨在评估非骨水泥全髋关节置换术后部分负重和完全负重对 2 年随访结果的影响。59 名女性和 41 名男性(平均年龄 61 岁)接受了非骨水泥 Spotorno 柄,并随机分为完全负重组和部分负重组。两组之间在 Merle d' Aubigne 髋关节评分、VAS 疼痛评分、柄迁移或影像学骨长入迹象方面无显著差异。所有股骨组件在影像学上均固定良好,在 24 个月时均显示骨长入。只要获得了牢固的初始固定,使用羟基磷灰石涂层的 Spotorno 型股骨柄的非骨水泥全髋关节置换术后即可立即完全负重。
