There is an excess of ulnar-sided skin on the forearm and wrist of the child with radial dysplasia relative to the radial side. In centralization and radialization procedures, there has been a trend to redistribute this skin by the use of local rotation flaps. Usually, these are dorsally located and can be used as access incisions for deeper structures such as tendons(1). A common form of the flap is bilobed in shaped, but this can be associated with some venous congestion(2).
