Arthroprostheses without cement in osteoarthrosis of the hip (preliminary report) (16 cases of Sbarbaro arthroprosthesis).

The authors report the results obtained with arthroprostheses without cement. In this preliminary report they examine sixteen cases treated with Sbarbaro's arthroprosthesis from 1972 to 1976, at the Orthopaedic Division of the Specialized Regional Hospital, Udine. They stress the efficacy of this kind of arthroprosthesis, which can be used in subjects under the age of sixty years who have severe bilateral lesions, especially of the femoral head. The operation is contraindicated when there is severe dysplasia of osteoporosis of the acetabulum. Weight bearing must be avoided for six months, the time required for the noncemented arthroprosthesis to become stabilized. The two poor results were attributable to local metabolic changes in one case, and general changes in another, rather than to the arthroprosthesis itself.
