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. We present 3 patients who received
a distal ulna vascularized graft with concomitant wrist arthrodesis for distal radius
segmental nonunion after complex distal radius fracture. This technique provides a
local pedicled graft that may be a simpler, more reliable, and less technically demanding
alternative.
