Abstract
Aim: Clinical and radiological intermediate-term results of non-cemented Standard- THR in younger patients up to 45 years old. Method: Between 1991 and 1996 forty-nine patients up to 45 years old (22–45, average 39) got 66 THR, 19 of them on both sides. Indications were: 42 Dysplasias (64%), 7 cases with failed osteo-synthesis of femur fracturs (11%), 5 cases of avascular necrosis (8%), 3 cases of Perthesñ disease (4%), 6 cases of rheumatoid arthritis and 3 cases of primary coxarthritis.64% of the patients with dysplasia have already been surgically treated. 51% of all replaced hips have already unterwent surgical treatment. In 35 patients with 50 THR (78%) a follow up (median 7 years, 5,5– 10) with clinical and radiological assessment was obtained. Results: No revision of stem and radiologically no obvious signs of loosening. Two revisions of the cup within the þrst year (one case of aseptic loosening and one case with persisting tendency of luxation)Complications: one intraoperative fracture of proximal femur, treated with a titanium cerclage, 4 luxations (one open reposition, one revision of cup, two closed repositions) no deep infection, 3 cases of incomplete postoperative pareses of femoral or peroneal nerve. WOMAC- score: 42% excellent, 44% good and 14% satisfactory results (average 29)Larson1- Hip-score: 60% excellent, 31% good and 9% satisfactory results (average 73)Conclusion: Non- cemented Standard- THR in younger patients showed good and excellent clinical results in 86 to 91% after intermediate- term follow-up and can therefore be recommended in the above mentioned indications.
