[Early experiences with the total mini hip-joint endoprosthesis (St. George Mini model) in dysplasia coxarthrosis].

The results of 106 patients with osteoarthritis secondary to severe congenital hip dysplasia and dislocations of the hip operated at the Endo-Klinik were evaluated after an average follow up of 21 months. 142 "St. Georg-Mini" total hips were implanted employing Refobacin-Palacos R. The clinical results were graded as "combined performance" which considered hip pain, walking distance, hip mobility and walking aids. In 93% of the cases "combined performance" was improved at follow up and 91.7% of the patients were satisfied with the result. The early (during hospitalization) and late (after discharge from hospital) complication rate which had an influence on the result at follow up was 2.1% (n = 3) and 3.5% (n = 4) respectively. There were no deep infections. An extended indication for total hip arthroplasty also for younger patients with severe osteoarthritis secondary to hip dysplasia is discussed and can be advocated.
