The surgical approach for treatment of scaphoid nonunion usually involves various combinations of screws and Kirschner wires, with or without bone grafts. This article reports our results with 36 dorsal-approach bone grafting procedures for treatment of scaphoid nonunion with Kirschner wires. Union was achieved in 89%. The average follow-up was 5 years. Flexion/extension averaged 76% of the opposite wrist, and grip strength was 88% of the opposite hand. Ninety-one percent of the employed patients returned to their original jobs. The dorsal approach provides satisfactory exposure for fragment reduction and bone grafting.
