Pediatric update #11. Congenital radioulnar synostosis. A new technique for derotational osteotomy.

Hyperpronation deformity due to congenital radioulnar synostosis has previously been managed by derotational osteotomy through the synostosis, while stabilization has been achieved with K-wires and a long arm cast. The technique presented here uses a small external fixation device that allows precise rotational correction and affords adequate stabilization yet avoids cast immobilization.
