Upper extremity reconstruction by vascularized bone transfers: results and complications.

Twenty-one cases of vascularized fibula transfer for upper limb reconstruction are reviewed. Recipient sites included the humerus in 11 patients, radius in five, ulna in three, and clavicle in two. Overall, primary bone union occurred in 15 patients (71.4%), and eventual union was achieved in 17 patients (81%). Two of the patients in whom there was failure to unite are minimally symptomatic, with stable fibrous nonunions. The most favorable results were achieved in cases of forearm bone reconstruction (100% union) and for long-bone reconstruction after tumor resection (83% union).
