["Physiological" healing and development of coxa valga in congenital dislocation of the hip (author's transl)].

At the University Orthopaedic Clinic Bonn, congenital dislocation of the hip has been treated since 1969, using the Hanausek-Apparatus. In this study the results of "physiological healing" and the development of coxa valga are compared with the results of our previous combined treatment regimen (traction in extension, followed by manual reduction, and initially fixation in the Lorenz position in plaster of Paris and then in Lange position). The term "physiological healing" is explained. The diagnosis coxa valga was made using the criteria of the DGOT working party on hip dysplasias. The problem of femoral head necroses is not considered; this has been reported previously. From this study we see a definite advantage of the functional treatment over the combined method. The "physiological healing" rate was substantially higher, and the development of coxa valga greatly reduced. The clinical results are further supported by animal studies from several authors.
