[Results of surgical correction of valgus deformity in childhood (author's transl)].

After surgical correction of valgus deformity in childhood by varus-rotations-osteotomy an increased incidence of recurrence of valgus is reported. The present analysis was performed to defind the indication for varus-rotations-osteotomy. 152 cases with operated hip joints were reviewed with regard to the clinical and radiological development. We found out that "postoperative insufficiency of the gluteal muscles = pathological revalgisation" does not induce revalgisation as postulated by other authors. Also discharging limping of the hip joint does not cause revalgisation. Postsurgical insuffiency of adductor muscles is not an obligatory but a potential cause for development of pathological revalgisation. And there is not correlation between the less frequent recurrence of anteversion and the pathological revalgisation, also there could not be found a correlation to lesions of the a trochanteric epiphysis due to the operation, or to the time of metal removing. According to our results the complication rate of recurrence of valgus becomes less frequent by age corresponding alteration of the CCD angle, even when it cannot be prevented.
