    AbstractPedicled vascularized bone grafts (Zaidemberg's technique) were used to treat 22 established scaphoid fracture nonunions, 16 of which were found to have avascular proximal poles at surgery. After a follow-up of 1-3 years, only six (27%) of the 22 fracture nonunions had united. Only two of the 16 nonunions with avascular proximal poles united, compared with four of the six nonunions with vascular proximal poles. We conclude that this technique of pedicled vascularized bone grafting may not improve the union rate for scaphoid fracture nonunions with avascular proximal pole fragments.
