[Follow-up results of Dega's acetabuloplasty (author's transl)].

From 1966 to 1974 231 acetabuloplasties were performed in 193 children. Dega's technique was not consequently observed in these operations. The follow-up was made in 166 children with 202 acetabuloplasties. 65 per cent of the operated hips were found within the normal range. The clinical examination revealed excellent and good results in 82 per cent. There was a relatively great number of failures due to technical problems, mainly in the first time. The results obtained allow the conclusion that Dega's acetabuloplasty is a valuable method in the operative treatment of the congenital hip in early childhood provided that it is performed with a good operative technique. Because of the possible failures we prefer now Pemberton's pericapsular osteotomy of the ilium.
