Abstract
The Herbert bone screw was used to treat 22 selected patients with established scaphoid nonunions. The indications for its use included evidence of avascular necrosis, proximal third fracture fragment, previous bone graft, fracture angulation or displacement, and a bipartite scaphoid. Treatment resulted in radiographic and clinical evidence of healing in 16 patients; 4 patients were symptom-free, but had incomplete healing as evidenced by radiograph; and 2 patients had persistent symptoms with radiographic evidence of nonunion.
