“…In SNAC wrist, unlike SLAC, the SLI ligament is intact. The lesion results from nonunion or malunion of the scaphoid fracture [4]. Approximately 12% of scaphoid fractures fail to undergo osseous union ("nonunion") and require internal fixation [17].…”

Scapholunate advanced collapse (SLAC) and scaphoid nonunion advanced collapse (SNAC) represent clinical entities identified by a pattern of predictable degenerative changes. They are the most common causes of wrist arthritis.Both entities can remain asymptomatic for many years and may go undiagnosed. Diagnosis is usually confirmed through clinical examination, which reveals progressive wrist pain and instability. Radiographically, degenerative changes in the radiocarpal and midcarpal joints are present, as well as nonunion of the scaphoid fracture in SNAC.The management differs according to the stage. Particularly in this review article, we reviewed the treatment options for stage II SLAC and SNAC wrist. In addition to the well-described surgical techniques such as proximal row carpectomy and four-corner fusion, alternatives such as capitolunate arthrodesis, three-corner fusion, and soft tissue procedures like capsulodesis and tenodesis are available.Proximal row carpectomy and partial arthrodeses yield comparable results. Soft tissue procedures are viable alternatives and are preferred in younger patients to avoid early salvage operations.

“…However, the initial injury in SNAC is the fracture and nonunion of the scaphoid, unlike in SLAC, where the injury of the SL ligament is the cause. SNAC lesions can also be caused by scaphoid malunion [4].…”
