Abstract
It is difficult to obtain successful union in nonunion of the scaphoid fracture with avascular necrosis. Masatomi reported a pedicled vascularized bone graft from the dorsum of the distal radius based on the posterior division of the anterior interosseous artery. The authors adopted this method for 2 cases with failed scaphoid union following conventional free iliac bone graft and Herbert screw fixation.
Case 1: A 20 year-old man with right proxymal scaphoid nonunion, who received free iliac bone graft and Herbert mini screw fixation 11 months after injury. The authors used this technique to treat the nonunion 8 months after the initial operation.
Case 2: A 23 year-old man with right proximal scaphoid nonunion, who received free iliac bone graft and Herbert screw fixation 2 months after injury. The authors used this technique to treat the nonunion 1 year after the internal fixation.
Both cases achieved successful bone union. Wrist pain was diminished markedly in both cases. The authors believe this method to be one of the admirable procedures for difficult nonunion of the proximal third of the scaphoid.
