Vascularized metacarpal bone graft for scaphoid non-union and Kienböck's disease.

A new vascularized bone graft from the base of the second metacarpal was used to treat scaphoid non-union and Kienböck's disease. In two patients with scaphoid non-union, the procedure promoted healing, even when the proximal segment was poorly vascularized. In one patient with Kienböck's disease, the graft held stable and wrist pain was markedly reduced. Further clinical experience may establish this procedure as an option for carpal bone fractures or disease.
