A new volar vascularization technique using the superficial palmar branch of the radial artery for the collapsed scaphoid nonunion.
Achieving union to prevent scaphoid nonunion advanced collapse wrist in the scaphoid nonunion is a challenging clinical problem. Much of the difficulty relates to the tenuous blood supply to the scaphoid. One unsolved reconstructive problem is the collapsed scaphoid that requires an intercalated wedge graft with proximal pole avascular necrosis. We offer a simple technique that only requires preservation of the superficial palmar branch of the radial artery that is typically ligated during the volar approach to the scaphoid. This technique can also be used during any open volar approach to the scaphoid to increase vascularity and healing.
