Congenital proximal synostoses of the ulna and radius do not require surgery in most of the cases, since the proximal synostosis can be sufficiently compensated by the wrist joint. In cases of considerable functional deficit, the synostosis has to be separated to enable re-ossification in a more advantageous position. We report on a patient with bilateral synostosis and a significant functional deficit due to the grotesque hyperpronation of the forearms. Following operative longitudinal separation and redressive casts, a good correction was obtained. X-ray imaging in lateral view documented the improved forearm position.
