Scapholunate advanced collapse

Scapholunate advanced collapse, also known as SLAC wrist, is a type of wrist osteoarthritis. It is the most common type of post-traumatic wrist osteoarthritis and is often the result of an undiagnosed or untreated rupture of the scapholunate ligament. The condition follows a predictable pattern of development, which was first described by H. Kirk Watson and Frederick L. Ballet in 1984. Diagnosis is made using wrist x-rays and supported by certain provocative tests. Management depends on the stage at the time of diagnosis and includes both non-surgical and surgical options.
