Objective: To investigate the feasibility and curative effect on transposition of the vascularized periosteal flap with dorsal branch of anterior interossea vessel. Methods: According to the research on anatomy, the vascularized periosteal flap with dorsal branch of anterior interossea vessel was designed for transposition of repairing the nonunion of ulna and radial fracture directly, and the scaphoid and lunate bone disease reversely. 16 nonunion of scaphoid, 2 necrosis of lunate bone and 1 nonunion of ulna were performed and observed. Results: All these 19 cases were followed up for 1 year. And it was found that satisfactory joint function and bone healing were obtained on 3 6 months after operation. Conclusion: The vascularized periosteal flap with dorsal branch of anterior interossea vessel can be applied to repair the bone nonunion and bone necrosis.
