title: Established nonunion of the scaphoid treated by volar wedge grafting and Herbert screw fixation.
abstract: We reviewed 26 consecutive men of mean age 28 years who had wedge bone grafting and Herbert screw fixation for symptomatic established nonunion of the waist of the scaphoid. The period between injury and operation averaged 30 months (10 to 96), and 11 of the 26 patients had had previous operations, seven with bone grafts. At a mean follow-up of 14 months (6 to 42) 25 fractures (95%) had united at a median time of four months. Symptoms were improved in all patients. The outcome was not related to the time between injury and surgery or to pre-existing degenerative changes. Previous surgery carried a worse prognosis. The technique is difficult but can achieve union even when previous surgery and bone grafting have failed. The usual result is improved function and some relief of pain.
