The main group of operated were children with stage III coxarthrosis due to osteochondrodysplasia (10) and congenital dislocation of the hip (6). The duration of follow-up is from 1 to 23 years. A good result was obtained in 13 cases, satisfactory - in 7. Unsatisfactory results were associated with suppuration (1) and instability of the endoprosthesis (2).
