Of 39 patients who had a SOM total hip replacement at Tanabe National Hospital from 1973 to 1979, 15 (16 hips) were re-evaluated about 10 years postoperatively by clinical examination and roentogenograms. One hip had been revised for aseptic loosening after 9 years.<BR>Clinical examination using the criteria of the Japanese Orthopaedic Association revealed a score for about 11 years of 87, compared with 71 after operation. Follow-up radiographs showed a 19 percent incidence of migration or tilting of the acethabular component and a 25 percent incidence of the femoral component. Thus the total incidence of loosening of either component was 44 percent, but even so the clinical results were excellent.
