[Frequency of necroses of the head of the femur in the treatment of the so-called congenital dislocation of the hip joint according to Hoffmann-Daimler (author's transl)].

The article reports on the results which can be obtained with the method described by Hoffmann-Daimler regarding the functional treatment of the so-called congenital dislocation of the hip joint. The report is based on a patient material of 110 children with 159 dislocated hips treated at the Orthopaedic University Clinic at Erlangen between 1971 and 1976. Observation of the course of the disease revealed a much lower rate of incidence of necrosis of the head of the femur than stated in literature, using the Hoffmann-Daimler method. The incidence of necrosis on pre-treatment of most children with other therapeutic methods, was 2.3% at the beginning of the Hoffmann-Daimler treatment, and increased to 12.7% up to the end of the treatment, dropping to 9.3% at the time of the follow-up examination.
