Scapholunate advanced collapse (also known as SLAC wrist) is a type of wrist osteoarthritis. SLAC wrist is the most common type of post-traumatic wrist osteoarthritis[1] and is often the result of an undiagnosed and/or untreated scapholunate ligament rupture.[2] The condition follows a predictable pattern of development, which was first described by H. Kirk Watson, M.D. and Frederick L. Ballet, M.D. in 1984.[3][4]
Epidemiology
editIn their initial study, Watson and Ballet identified SLAC wrist as the most common form of wrist osteoarthritis, occurring in 57% of 210 patients with wrist osteoarthritis.[3] SLAC wrist is more common in males, manual laborers, young people, and patients with a history of wrist trauma.[5]
Diagnosis
editScapholunate advanced collapse is a radiographic diagnosis. The Watson and Ballet classification identifies three stages of progressive wrist osteoarthritis that can be identified on a standard posterior-anterior (PA) wrist x-ray.
