[The development of the dysplastic hip joint after conservative treatment (author's transl)].
The roentgenograms were evaluated of 220 patients (159 female, 61 male) with 61 luxations, 77 subluxations and 203 dysplastic hip joints which were a maximum of 2 years old during treatment and had been under observation for between 2 and 17 11/12 years. The CCD-, CE- and Ac-angles were measured. 1. The CCD-angle develops relatively independent of the therapy for the first few months. In the long term, the abduction treatment leads to a straightening up of the femoral neck. Here a physiological component apparently has an effect which reduces the straightening after several years. 2. The CE-angle rapidly becomes enlarged during the first few months, later the rate is slower. Three years after treatment began, the CE-angle was normal in 83.6% of the patients. 3. The Ac-angle decreases rapidly during the first 6 months. Three years after the beginning of treatment, 65.7% of the patients had a norm of less than 20 degrees. 4. All angles show a positive correlation of their beginning and end values i.e. light dysplasias have the best prognosis. 5. The monotherapy with a spreader pant showed a particular advantage over the combination treatment and plaster fixation. 6. The best result was achieved with treatment beginning before the age of 6 months. Boys showed a better tendency to heal. A difference in sides could not be shown.
