The medium-term results of cementless Lord-type hip prosthesis.

The results of 58 cementless total hip prostheses (Lord madreporous type) were evaluated 4 to 7 years after implantation. The functional results were generally satisfactory, although in approximately half the cases some pain was still present. Radiographic examination allowed us to analyse the response of the diaphyseal bone to the different situations of the endomedullary implant. Acetabular wear, which is one of the factors which may influence the long-term results, was also evaluated.
