Retrograde compression screw fixation of acute proximal pole scaphoid fractures.
Seventeen consecutive patients with acute unstable proximal pole scaphoid fractures were managed over the past 5 years with open reduction and internal fixation. Four fractures were displaced, with greater than 1 mm of fragment offset and intercarpal malalignment. The operative technique consisted of a dorsal approach to the scaphoid, radius bone grafting, and freehand retrograde Herbert compression screw fixation. The patients were evaluated at an average of 37 months (range, 12-63 months) after surgery. All fractures healed within 13 weeks (average, 10 weeks). Functional wrist range of motion and grip strength were achieved in all patients. No patients developed osteonecrosis or radioscaphoid arthritis. Open reduction and internal fixation rather than primary casting is a better means of reducing the complications of delayed union, nonunion, and irreparable osteonecrosis that often occur after acute proximal pole scaphoid fracture treated with cast immobilization.
