Techniques for Vascularised Bone Grafting in Scaphoid Nonunion.
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.
