The treatment of scaphoid nonunion. A review of a novel technique using precision bone grafting compared with Herbert screw fixation and bone graft.
We have retrospectively reviewed the results of 40 consecutive patients with nonunion of the scaphoid treated by the senior author (PG) between 1993 and 1996. These comprised two groups of patients. Group 1 comprised 20 patients treated between 1993 and 1994, with a Herbert screw and autograft, and Group 2, which also comprised 20 patients treated with the precision bone grafting technique which we describe. The precision bone grafting technique employs simple instrumentation to harvest bone percutaneously from the iliac crest and then insert it at the scaphoid nonunion site. The evaluation consisted of a clinical and radiological assessment of union and wrist function. Our review demonstrates a higher rate of union with the precision bone grafting technique than by the Herbert screw fixation with bone grafting.
