[Quality assurance in hip prosthesis surgery. New type hip prostheses, review of a 3-year material]

This article deals with the short-term results of prosthetic replacement of the hip joint. The investigation was carried out three years after the introduction of a new hip prosthesis - the ITH (" International Total Hip") prosthesis. Our results were analysed retrospectively, the primary goal being quality assessment of the results of our hip surgery. We found that the results of hip prosthetic surgery with the ITH-prosthesis were satisfying, although the frequency of complications was rather high: 185 implantations of the ITH-prosthesis gave 13 cases of deep venous thrombosis; one case of deep infection and subsequent revision surgery; four cases of dislocation of the prosthesis, of which two cases have been subsequently revised; one case of perforation of the femur with later revision; and one case of permanent paralysis of the femoral nerve. The overall rate of revisions was 2.7%. The overall survival of the prosthesis according to Kaplan Meier was 97% after three years.
