Vascularized Bone

Scaphoid nonunion is a challenging situation for orthopaedic surgeons. Nonunion rate is especially high in proximal pole fractures of the scaphoid due to tenuous retrograde blood supply. The use of pedicled vascularized bone grafts for the treatment of scaphoid nonunion provides both good clinical and radiological outcomes. The preserved vascularity of the graft leads to better bone remodelling, less osteopenia, faster incorporation and better maintenance of bone mass compared to the conventional non-vascularized grafting. Pedicled vascularized bone grafts also allow the correction of the carpal alignment and humpback deformity of the scaphoid. Clinical and radiological results have been satisfactory and promising, making us anticipate that the role of vascularized bone grafting for the treatment of carpal diseases will increase.

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.

Vascularised Bone Graft

Avascular necrosis (AVN) of the scaphoid is common following proximal pole fractures due to an arduous retrograde arterial vascular supply and it is a challenge to the hand surgeon. The treatment for scaphoid non-union with avascular necrosis is vascularized or non-vascularized bone grafts. Non vascularised bone grafts (NVBGs) can be categorized as autograft or allograft and cancellous or cortical bone grafts. Vascularised bone grafts promote biological healing and revascularizes ischaemic bone and they are free or pedicled grafts. Pedicled vascularised bone grafts maintain the vascular supply of the donor bone graft and this leads to better bone remodelling, less osteopenia, faster incorporation and better maintenance of bone mass compared to the non-vascularised graft with good clinical and radiological outcomes. In this paper, we have treated avascular necrosis of scaphoid with a pedicled vascularised bone graft based on the 1, 2 intercompartmental supraretinacular artery (1, 2-ICSRA) that resulted in a favourable outcome.
