[Results of hip joint replacement with ceramics partial endoprostheses].

Report about our 5 years experience with cementless and cemented partial ceramic hip prostheses in altogether 58 cases. Indication, in old age, mostly in case of fresh or elder femoral neck fracture; in younger age, chiefly in case of partial femoral head necrosis and preserved cartilage of acetabulum. Typical complication of this type of prosthesis: early luxation, especially in case of acetabular dysplasia, which, therefore, has to be regarded as contraindication for hemiarthroplasty. Satisfying subjective and objective middle-term-results in older age. Failure of arthroplasty with necessity of later implantation of acetabular component only in two cases of osteoporotic bone destruction. In younger age, the results weren't that satisfying. Because of higher activity and strain there was a higher rate of wear of acetabular cartilage; twice, we had to perform later implantation of ceramic socket, up to now.
