Pure cancellous graft deserves consideration for its superior osteoconductive and osteoinductive characteristics, and its faster time to incorporation as compared to either cortical or corticocancellous graft. However, the use of cancellous graft demands fixation that can structurally support the graft as it incorporates. The authors believe that the plate provides successful fixation for this technique because of specific attributes: (1) maintenance of the nonunion defect and preservation of scaphoid height to allow for application of non-structural cancellous graft; (2) rotational control for small proximal pole fractures; and (3) minimizing space-occupying metal within the bone, and consequently maximizing the surface area of bony contact for healing.
