[Semicircular incomplete osteotomy of the supra-acetabular area of the hip joint and its outcome].

The paper is devoted to the surgical treatment of the children with dysplastic pre- and coxarthroses, namely to the reconstruction of the supraacetabular area of the hip joint by means of incomplete semicircular osteotomy, which has allowed to reduce the terms of the treatment, to exclude a further recurrence of the deformation and to interrupt the phenomena of arthrosis that are present. In all the cases of the 50 patients who had been operated (aged 3 to 14 years with the follow-up period up to 10 years) there were good anatomical and functional results. The average mark according to the CITO scale was 4.6.
