Abstract
Most nonunions of the carpal scaphoid bone can be treated with a high rate of success by use of conventional bone grafting techniques. However, fractures with a small proximal pole fragment may be difficult to treat by use of these techniques. Nine patients with nonunion and three patients with unstable proximal pole fractures were treated with retrograde dorsal Herbert screw fixation and adjunctive bone grafting. Follow-up averaged 25 months. Of the 12 patients, the fracture healed in 11 and one fracture remained ununited. This technique has been successful in our practice and should be considered in the treatment of small proximal pole nonunions and displaced proximal pole fractures.
