采用现代骨水泥技术行全髋股骨头假体修正手术

Revision of the femoral component with second-generation cementing techniques:an average of 6 year' follow-up study

目的 探讨现代骨水泥技术行全髋股骨头假体修正手术 (RTHA)的方法和疗效。方法 采用RTHA治疗 8例 8髋 ,临床和X线摄片随访 3～ 8年 ,平均 6年。结果 功能优良 5髋 ,尚可 2髋 ,再RTHA 1髋。股骨头假体肯定松动 2髋 ,很可能松动 1髋 ,可能松动 5髋。结论 现代骨水泥技术仍未从根本上改善RTHA的疗效 。

Objective To summarize and analyse the surgical technique and results of revision total hip arthroplasty(RTHA).Methods Eight cases(eight hips) of RTHA performed by the use of the second generation cementing techniques.Results At an average of 6 years′ follow up,clinical results were evaluated as excellent or good in 5 hips,and fair in 2 hips,with one hip undergoing a second revision.X ray revealed that definite loosening of the femoral component in 2 hips,probable loosening in one hip and possible loosening in five hips.Conclusion The second generation cementing techniques will not improve the results of RTHA completely.We believe the main cause might be that cementing techniques does not reconstruct any structural bone loss in patients with RTHA.
