Scaphoid reconstruction with vascularized bone grafts from the distal radius

The aim of the present technical report is to describe the alternative solutions for the reconstruction of scaphoid nonunions with pedicled vascularized bone grafts from the distal radius. The surgical technique for the reconstruction A. of proximal scaphoid nonunions with pedicled bone grafts (based on the 1,2 or on the 2,3 intercomparmtental arteries) or with capsular bone grafts from the dorsal distal radius and B. of waist nonunions of the scaphoid with grafts from the palmar distal radius, pedicled on the palmar carpal arch, is presented. Vascularized bone grafts from the adjacent radius are used for the treatment of scaphoid nonunions to enhance union and to revascularize a nonviable proximal pole. The most suitable graft is selected according to the location of the nonunion (at the waist or the proximal pole of the scaphoid) and to the previous procedures/scars at the wrist level.
