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.
