DONOR SITES FOR PEDICLED SKELETAL GRAFTS OF THE HAND, WRIST, AND FOREARM

Pedicled bone and periosteal grafts provide successful reconstruction of skeletal problems of the distal radius, wrist, and hand. The purpose of this study was to evaluate the available alternatives and to propose the most suitable skeletal grafts for the reconstruction of the distal radius, and the carpal and hand bones. The alternative donor sites (dorsal and palmar distal radius, and metacarpals), their pedicles, and the potential coverage area in relation to specific wrist and hand pathology were determined in the cadaveric dissections. In the clinical setting, 75 pedicled grafts were used for the treatment of scaphoid nonunions (62 cases), lunate necrosis (8 cases), reconstruction of the metacarpal defects (2 cases), and wrist fusions (3 cases). All alternatives have the advantage of a single approach that may be performed under tourniquet control, from the same team. Among the available alternatives, surgeon's familiarity plays the most important role for the final selection of the graft. (c) 2009 Wiley-Liss, Inc. Microsurgery 29:408-412, 2009
