Vascularized Bone

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.

Vascularized Bone

We present the surgical outcomes of non-vascularized bone grafting taken from the iliac crest in 24 patients with scaphoid nonunion and avascular necrosis. The Fisk-Fernandez technique was used in 11 patients, and cancellous bone grafting was used in 13 patients. Bony union was achieved in 22 of the 24 patients. Non-vascularized iliac bone grafting can be used for the surgical management of scaphoid nonunion with avascular necrosis. Although revascularization of the proximal fragment after surgery was not evaluated, bony union was confirmed in nearly all patients. Level of evidence: IV

Grafting Procedure

Scaphoid nonunion with avascular necrosis of the proximal pole remains a difficult problem. We have endeavoured to heal the fracture, restore scaphoid height and revascularize the proximal pole of the scaphoid by means of a vascularized dorsal interposition graft from the distal radius. The procedure has resulted in union of six of ten fractures. Fractures that healed had not been treated by a previous bone grafting procedure. Dissatisfaction was due to loss of motion in patients who had healed fractures, and pain in those patients with persistent non-unions.
