SNAC wrist (Scaphoid Nonunion Advanced Collapse) is a pattern of post-traumatic osteoarthritis in the carpus that occurs after scaphoid non-union that progresses sequentially causing pain and functional loss. Due to its late diagnosis, anatomical or salvage therapeutic measures must be decided to preserve functionality. This literature review will focus on knowing how to identify and stage the injury, establish a management algorithm for each case, and compare the available alternatives. We will review the indications and considerations of the most frequently used techniques and the support of the current evidence. 

Keywords: SNAC, scaphoid nonunion, wrist osteoarthritis, proximal row carpectomy, partial arthrodesis
