Surgical treatment results in scaphoid nonunion.

Fracture of the scaphoid is the most common fracture in the wrist. We retrospectively reviewed 42 cases of established nonunion of the scaphoid that had been treated by four methods: with two Kirschner wires (K wires) and pronator quadratus pedicled bone graft in 5 patients; AO cannulated screw and graft in 8 patients; Herbert screw and graft in 19 patients; and two K wires and graft in 10 patients. Follow-up ranged from 1 to 5 years (between January 1995 and January 2000). Radiographs and computed tomography (CT) scans were analyzed for confirmation of osseous union. The average period of clinical and radiologic union was 13.2 weeks (range, 10 to 33 weeks). There was a significant improvement in the grasping power, radiologic healing, clinical satisfaction, and pain relief in the patients who had operation.
