[Surgical treatment of congenital hip dysplasia]

Between 1967 and 1977 we operated on 83 hips with congenital dysplasia of the hip. We needed 3.25 procedures per patient to achieve a good final result. While using an improved protocol between 1977 and 1985 we operated on 155 hips and then we needed only 1.38 procedures per patient to achieve a good final result. The improved more precise treatment protocol gave us the same good results with less operation procedures.
