Abstract

A cemented revision of failed total hip arthroplasty is prone to early mechanical failure. Cementless revision seems to be much more promising. We present our 2 year follow-up of 19 cementless revisions using the R.M. isoelastic stem. During follow-up special attention focused on the restoration of bone stock on the femoral side of the arthroplasty. Bone stock deficiencies encountered during the operation were managed with grafts. Other complications to solve during the procedure were encountered frequently. The average follow-up was 58 months. Rating the results following Merle d'Aubigné and Postel showed very good or good result only in half of the cases, one case needed a revision. Nevertheless good restoration of bone stock was observed in nearly all cases. A greater number of patients should be followed for a longer period of time to establish the exact role of this prosthesis design.
