Abstract

Eighty primary total hip arthroplasties were performed using a first- generation modular femoral stem inserted without cement. Modular distal sleeves made of methacrylate were used in 33% of the hips. Dorr type B or C femoral geometry was present in 80% of the cases. The mean follow-up period was 81 months with a minimum of 48 months. Satisfactory clinical results were observed in 74% of the hips at the final follow-up visit. Revision of the stem had been performed in 14% of the hips, all for aseptic loosening. The overall mechanical failure rate was 48%. Canal fill by the stem was not any better with the sleeves than without. The incidence of failure, however, was less in those hips in which sleeves were used. Femoral osteolysis was present in 19% of the hips. The experience with this particular stem design has been disappointing.
