Femoral cement within cement technique in carefully selected aseptic revision arthroplasties.

摘要

The aim of this study was to evaluate the clinical and radiological results in a group of patients who underwent aseptic revision hip arthroplasty using the cement within cement (CWC) technique. Between 1999 and 2005, 37 aseptic revision hip operations were performed. There were 30 women and five men, with an average age of 68 years. The reasons for revision were femoral stem fracture, cup failure, acetabular protrusion after hemi-arthroplasty and recurrent dislocation. At an average follow-up of 46 months, none of the patients required further femoral revision. The average post-operative Merle D'Aubigne score was 16.6 points (p<0.05). No evidence of radiological stem failure was observed and no femoral component was considered to be at risk for loosening. In this series of patients, the CWC technique provided consistent with high functional outcomes. This valid and effective alternative should be considered in carefully selected aseptic cases.
