[Congenital idiopathic clubfoot. Etiology, pathomorphology, therapy and results].

The congenital clubfoot is still a challenge for any orthopaedic surgeon and a subject of controversial and unresolved aspects. In this study the technique and results of 312 clubfeet which were treated at the pediatric orthopaedics department of the Speising Hospital between 1979-1987 are reported. Conservative treatment was successful in only 15% of our patients. 85% had to be corrected by a surgical intervention, mostly by an extensive posterior release. New aspects of pathomorphology and of surgical management of the deformity are mentioned. The benefit of the Cincinnati-incision is stressed and has been proved by this study.
