[Our experience with the uncemented isoelastic total hip prosthesis].

Between May 1981 and May 1987, 250 isoelastic hip prostheses were implanted. The first 180 (from May '81 till May '86) were called for a visit. 130 (72%) came and were assessed with a minimum review time of 1 year. We ignore the reasons for which 28% of the patients did not turn up (death or others). 81% of the patients had good or very good results after surgery. Three patients developed infections (2.3%); none of these was revised. Four developed loosening of the femoral component; two of these underwent revision surgery and are doing well now. We did not notice any loosening of the acetabular component. The recommended period of gait support was of 2 months of no weight bearing with two canes and of two months of partial weight bearing with one cane. No component had broken. We had 1 femoral fracture incurred during surgery which healed with routine management. These early results are very encouraging, but the effectiveness of this prosthesis will require longer follow-up data to be confirmed.
