Repeat Russe bone grafting after failed bone graft surgery for scaphoid non-union

We report the long-term outcome of repeat Russe bone grafting after failure of a previous Russe graft for scaphoid non-union. 15 patients were followed for a mean of 71 months after their last surgical procedure. 11 patients had undergone a single previous Russe graft and four patients had two previous graft attempts. Internal fixation was used in only three patients. Eight out of 15 (53%) patients achieved union after a single repeat graft and one out of four united after a third attempt. When union was achieved, range of motion was unchanged, grip strength was increased 10%, and pain was slight to none, allowing return to full employment in seven out of the nine patients. All patients who did not achieve union have either undergone a salvage procedure or are contemplating one. Based on the literature and our relatively low rate of union without internal fixation (53%), we recommend supplementary internal fixation if repeat Russe bone grafting is undertaken. When union is achieved, satisfactory results can be expected.
