title: Silicone replacement for non-union of the scaphoid. 7 cases followed for 9 (5-18) years.
abstract: In the years 1971-1983, 7 patients underwent excision of the scaphoid with replacement by a silicone rubber implant because of painful nonunion of a scaphoid fracture. The patients were reviewed 9 (4.5-18) years postoperatively. All patients returned to work, 2 patients being completely pain-free, 4 having only occasional pain on heavy activity, and 1 having pain on normal activity. The range of motion, power and pinch grip were near-normal in all. Radiographic examination showed progressive dorsal intercalated segment instability with carpal collapse and arthrosis. There was no evidence of fragmentation of, or reaction to the prosthesis. 1 prosthesis was dislocated, and no patient required a revision operation.
