SLAC and SNAC Wrist Injuries

Kashif Memon - SLAC (Scapholunate Advanced Collapse) and SNAC (Scaphoid Nonunion Advanced Collapse) are common post-traumatic wrist arthritis conditions.

- These conditions are characterized by radial-sided wrist pain and can be caused by trauma, inflammatory arthritis, or neuropathic conditions.

- The diseases progress through stages, starting from arthrosis between the radial styloid and scaphoid, and advancing to arthrosis of the radioscaphoid joint and radiocapitate joint.

- Treatment options vary based on the stage of the disease and include conservative management, wrist splinting, injections, denervation, radial styloidectomy, limited carpal fusion, and four-corner fusion.

- Symptomatic patients with scaphoid nonunion should be treated, while asymptomatic patients may be observed without treatment. Motion-preserving procedures can be considered for young individuals, but fusion is often the only option for pain relief.
