Necessity of grafting in scaphoid nonunion fixation: A comparative outcome analysis

Figure 5 Failure of union after graft-augmented fixation for waist nonunion. A: Postoperative anteroposterior radiograph one month following fixation of a waist nonunion using cortico-cancellous graft from the iliac crest via the dorsal approach; B: Follow-up radiograph at two months revealing a sunken Herbert screw; C-G: Anteroposterior wrist radiograph and computed tomography slices at eight months showing union failure, graft resorption, and screw penetration into the scapho-trapezial joint.
