Congenital radioulnar synostosis (CRS) is a rare anomaly involving abnormal fusion of the proximal radius and ulna during development. It can be severely disabling if the proximal radioulnar joint is severely hyperpronated. Compared with trauma-related radioulnar synostosis, congenital synostosis usually associated with narrowing of the interosseous membrane, contracture of the surrounding soft tissue, and fibrosis or atrophy of the supinator muscles. The ideal treatment for congenital radioulnar synostosis is to restore the rotation function and to prevent recurrence of the bony bridge. Because of its highly variable severity and different presentations, many operative methods have been reported and the indications for specific method remain controversial. No standardized corrective procedure exists as yet.
