[Preliminary results of arthroplasty of the hip, using a pair of sealed double cups].
Arthroplasty of the hip with a pair of locked cupolas uses a metal cupola and a polyethylene cotyloid cupola. Ancillary instrumentation and 3 sets of protheses allow an acrylic fixation using a thin layer of cement. The authors report their experience with 75 surface replacement arthroplasties. The initial complications seem related to errors made in at the outset in drilling the femur, thereby compromising the solidity of the neck and the vascularization of the head. These results can be transposed upon the case of total conventional prothesis. The indications, which principally incluse centered coxarthrosis, have been widened to comprise necrosis limited to the femoral head, to rheumatoid polyarthritis, to ankyloses of the hip in a bad position, and to re-setting of non cemented cupolas. These encouraging results should be tempered by their short follow-up period (less than 2 years), and the present uncertainty as to the future performance of the lock joints and the wear of the polyethylene.
