[Follow up study of 997 total hip endoprostheses with special reference to late results 9-11 years after operation].
81.1% of a total of 1230 total hip arthroplasties could be reviewed by means of questionaries between 4 and 11 years after the operation. There was clear evidence for wors results in the long term group (between 9 and 11 years postoperatively) as to pain and ability to walk. In the short-term group of 1972-76 8.4% are not satisfied with the results of the operation, but in the long term group of 1970 this refers, as to be expected, to 23.5%. The same trend has been stated what aseptic complications are concerned: 42.7% clinically relevant ectopic ossifications and non-infectious implant loosenings in the long term group as compared with only 5.6% in the short term group. 1131 Müller prostheses were implanted. In this group 61 reoperations because of aseptic complications were necessary. Of all implanted Müller prostheses models the one with the middle neck length revealed the lowest rate of loosenings. Postoperative infections (both early and late) indicated a re-operation in 0.5%.
