Primary bone grafting with pedicled flap cover for dorsal combined injuries of the digits.

Abstract

Twenty digits in 15 patients with dorsal combined tissue loss were treated by radical debridement, primary non-vascularised iliac crest bone graft and immediate lower abdominal flap cover between 1996 and 2006. The average length of the bone grafts was 3.3 (range 2.5-5) cm. No extensor tendon reconstruction was carried out. The flaps were divided at 3 weeks without delay. Permissible thinning of the flap was done at the time of division of flaps. No secondary procedure was done. All patients were retrospectively reviewed and X-rays obtained. Radiological union was achieved in 18 of 20 digits. One bone graft was removed because of infection. One bridging bone graft united with the distal phalanx but had a painless non-union with the proximal phalanx. There were no flap complications. Bone graft length resorptions of 20% and 15% occurred in two terminal bone grafts. We recommend this protocol as a solution to this challenging problem.
