Internal fixation of scaphoid injuries using the Herbert screw through a dorsal approach.

This prospective study reports on the use of the Herbert screw for fixation of fractures and nonunions of the scaphoid through a dorsal approach. In cases of delayed union and nonunion, screw fixation was combined with bone grafting. Twenty-five patients were treated in this manner, and union rates of 100% for acute fractures and 87% for delayed union and nonunion were achieved.
