Round table discussion. The management of proximal scaphoid nonunion

The management of scaphoid nonunion, although relatively common, continues to pose challenges, especially if complicated by avascular necrosis of the proximal pole, humpback or dorsal intercalated segment instability deformities, and early scaphoid nonunion advanced collapse. In this round table article, four surgeons were asked to answer key questions on a clinical example of a proximal scaphoid nonunion to outline their approach and rationale in their preferred treatment choices. The current panel of experts leans towards arthroscopic methods of treatment and most agree that arthroscopic bone grafting has become an important and revolutionary treatment option, which has yielded excellent results. However, both open and arthroscopic grafting are validated methods of treatment and which is to be performed is largely based on the surgeon's preference.
