Scaphoid Reconstruction

Background: Fractures of the proximal pole of the scaphoid can be difficult to heal because of its limited vascular supply. Furthermore, nonunion with avascular necrosis and secondary fragmentation makes surgical reconstruction a challenging procedure. Method: We describe a technique and report the outcome of a proximal hamate autograft to treat a proximal pole scaphoid nonunion with avascular necrosis. Results: At 3.5 years post reconstruction, the patient remains asymptomatic with union of his scaphoid reconstruction without any evidence of scapholunate instability. Conclusion: Proximal hamate autograft is a useful technique for addressing proximal pole scaphoid nonunions with avascular necrosis.

Scaphoid Fractures

Nonunion of the scaphoid remains a significant problem in the management of scaphoid fractures. Recurrent persistent nonunion following attempts at internal fixation, and nonunions with sclerosis or avascular necrosis of the proximal pole of the scaphoid are particularly challenging. However, the aims of restoration of scaphoid anatomy and the achievement of union of the scaphoid remain the foundation pillars of scaphoid treatment. In recent years, several techniques for using vascularised bone grafts in the treatment of these difficult problems have been described. This article will review the currently described treatments, provide an overview of our unit experience with these techniques, and also describe a technique for in situ vascularisation of a conventional bone graft.

Grafting Procedure

Scaphoid nonunion with avascular necrosis of the proximal pole remains a difficult problem. We have endeavoured to heal the fracture, restore scaphoid height and revascularize the proximal pole of the scaphoid by means of a vascularized dorsal interposition graft from the distal radius. The procedure has resulted in union of six of ten fractures. Fractures that healed had not been treated by a previous bone grafting procedure. Dissatisfaction was due to loss of motion in patients who had healed fractures, and pain in those patients with persistent non-unions.
