Vascularised bone graft for the treatment of non-union of the scaphoid.
A 4/5 compartment pedicled vascularised bone graft from the distal radius combined with internal fixation with a Herbert type cannulated screw was used to treat non-union fractures of the proximal pole of the scaphoid in 13 patients. Non-union was identified on plain radiographs alone. Uneventful clinical and radiological healing was achieved in 11 patients. One patient had progressive signs of failure of the fixation of the screw at the proximal pole; the screw was changed and the fracture was stable at reoperation. One patient had a fall postoperatively, radiographs taken at follow-ups showed only partial healing, and he had a bone graft 12 months later. Twelve patients had clinical and radiological union of the fracture, and one patient fibrous healing alone. The technique may improve healing of non-union of fractures of the proximal pole of the scaphoid, but it is still a technical challenge.
