Figure Legend: Scaphoid fractures usually occur as an isolated fracture (1) but may be part of a larger injury complex (2). Oblique (3), comminuted (4) and proximal (9) fracture lines are prone to nonunion. Nonunion may be radiographically subtle (5), cystic (6) or hypertrophic (7). The majority of scaphoid nonunions progress to a pattern of radioscaphoid and midcarpal arthritis referred to as Scaphoid Nonunion Advanced Collapse or "SNAC wrist" (8, 9).
