[Tentative results after implantation of isoelastic cementless hip-joint socket].
During the 3 years from 1979-1981 in 3 Austrian Accident Departments, 196 isoelastic acetabular components for total hip replacements were implanted. 3 different models were used as components of the femoral head. 194 acetabula were implanted without cement. In two cases cement had to be used because of extreme porosity or protrusion. Follow-up examination of 178 patients after 14-48 months yielded a good clinical result in 161 cases. 16 patients reported occasional pain, 38 patients had a slightly positive and 16 a definitely positive Trendelenburg's sign. On X-ray film 48 patients showed no change in bone structure at the borderline between bone and implant. Sclerosis and increased density of the surrounding bone were observed more frequently than formation of radiolucent seams or cysts. No definite signs of loosening were seen.
