Reverse radial artery bone flap reconstruction of segmental metacarpal losses.

Abstract

A vascularised bone segment of the distal radius was harvested as a distally based flap to treat segmental metacarpal bone loss in three patients. One reconstruction followed resection of a giant cell tumour excision and the other two were to replace traumatic bone loss. The bone defects were in the second metacarpal in two cases and in the second and third metacarpal in one case and included three shaft and one distal metacarpal reconstruction. The mean length of the metacarpal defects was 6 cm. All of the flaps survived and no complications occurred at the donor site. Clinical and radiological union was established in all cases after an average of 3 months.
