In patients with segmental nonunion of the distal radius, the distal ulna and distal radioulnar joint may not be salvageable. As an alternative to a vascularized free fibula, a pedicled distal ulna vascularized graft is a useful salvage technique. The procedure relies on the vascular bundle of the pronator quadratus and the dorsal oblique arterial anastomosis between the anterior and posterior interosseous arteries running along the interosseous membrane as the pedicle.

Methods: We retrospectively identified 50 patients with scapholunate advanced collapse wrist changes who had 4-corner arthrodesis. Thirty-four patients were able to return and complete all follow-up evaluations.
