Domestic Meeting of the European Hip Society edition:8 location:Madrid, Spain date:11-13 June 2008
Hip involvement in inflammatory arthritis is a common entity. Total hip replacement offers the most reliable surgical treatment option for pain relief and functional improvement. Fifty-two total hip replacements (THR) were carried out in 30 patients. The mean follow-up was 11 years (range 5-17, SD 3.4). The mean age at operation was 27 years (range17-35). The modified Charnley-Merle-d’Aubigné score improved from 8.2 to 16.5 after the operation. All patients had a cemented doubled tapered polished femoral component. There were 11 cemented and 41 uncemented cups. One patient who had a bilateral single stage THR died 8 years after the index operation with both prostheses functioning well. In the remaining 29 patients with 50 THR there were no revisions of any cemented stem.
There were 3 revisions of cemented cups respectively 11, 13 and 16 years postoperatively. All cups were revised to an uncemented cup. One uncemented cup showed an osteolytic lesion in zone II. Although the uncemented cups had a slightly shorter follow-up there were less radiolucencies and no revisions in the uncemented cups compared to their cemented opponents.
Conclusions: THR gives excellent pain relief and improvement in function in young patients with inflammatory involvement of the hip joint. Cemented stem survival is excellent. Uncemented cups scored better than their cemented opponents.
