Case Discussion

Scaphoid non-union advanced collapse (SNAC) can occur secondary to scaphoid fractures, specifically non-union of scaphoid fractures. The proximal fragment remains at the lunate while the distal fragment begins to rotate into flexion creating abnormal contact in the radio-scaphoid compartment that will progressively get worse.
