A vascularized bone graft from the dorsoradial aspect of the distal radius was used with internal fixation to treat nonunion of the scaphoid in ten patients who had not received any previous surgical treatment. Five cases were classified as Lichtman type I and five as type II. The average age was 30 years (range, 18–40 years). Associated avascular necrosis was observed in five cases. Post-operatively pain was relieved and union was achieved in all cases. The mean time to union was 6.5 weeks. Range of motion, grip strength and pinch strength were also restored satisfactorily. These results suggest that this vascularized bone graft should be used as the primary procedure in Lichtman type I and II of scaphoid nonunions, regardless of the presence of avascular necrosis of the proximal pole.

First Dorsal Metacarpal Artery

Four patients with chronic nonunion of the scaphoid were treated by a vascularized bone graft based on first dorsal metacarpal artery. The mean duration of the nonunion was 28.5 months (range 12–48 months). There was avascular necrosis in all patients confirmed by magnetic resonance imaging (MRI). None of the patients had previous attempts at surgical reconstruction. Two fractures were localized at the waist one in the distal part and one at the proximal pole. Osseous union of the scaphoid was confirmed by X-ray in all patients in an average of 2.1 months. We recommend this technique for the treatment of established scaphoid pseudoarthrosis with avascular necrosis since it is associated with minimal morbidity and predictable good results.

Pedicled vascularized bone grafts (Zaidemberg’s technique) were used to treat 22 established scaphoid fracture nonunions, 16 of which were found to have avascular proximal poles at surgery. After a follow-up of 1–3 years, only six (27%) of the 22 fracture nonunions had united. Only two of the 16 nonunions with avascular proximal poles united, compared with four of the six nonunions with vascular proximal poles. We conclude that this technique of pedicled vascularized bone grafting may not improve the union rate for scaphoid fracture nonunions with avascular proximal pole fragments.

Scaphoid fractures frequently present with nonunion and proximal pole necrosis, the treatment of which is bone grafting. Pronator quadratus pedicled vascularized bone graft is an option especially in the setting of proximal pole necrosis. We describe our experience of managing such scaphoid non-unions using pronator quadratus pedicled vascularized bone graft. Six patients were managed using pronator quadratus pedicled vascularized bone graft following scaphoid fracture nonunion with proximal pole necrosis. All patients had good fracture healing and symptom resolution. Mild deficit in wrist extension was noted in all patients. Pronator quadratus pedicled vascularized bone graft is an attractive option for managing scaphoid nonunion. Lying adjacent to the fracture site, bone can be harvested and transferred without making any other incisions. This procedure introduces another source of blood supply to the fracture site and hence improves fracture healing.
