Trapeziometacarpal osteoarthritis (TMC OA) is, also known as osteoarthritis at the base of the thumb, thumb carpometacarpal osteoarthritis, basilar (or basal) joint arthritis, or as rhizarthrosis. [ 3 ] [ 1 ] [ 2 ] This joint is formed by the trapezium bone of the wrist and the metacarpal bone of the thumb.
Wrist osteoarthritis is gradual loss of articular cartilage and hypertrophic bone changes (osteophytes). While in many joints this is part of normal aging (senescence), in the wrist osteoarthritis usually occurs over years to decades after scapholunate interosseous ligament rupture or an unhealed fracture of the scaphoid.
[1] [3] Joint replacement surgery may be an option if there is ongoing disability despite other treatments. [2] An artificial joint typically lasts 10 to 15 years.

SLAC wrist is the most common type of post-traumatic wrist osteoarthritis [1] and is often the result of an undiagnosed or untreated scapholunate ligament rupture.

The carpometacarpal (CMC) joints are five joints in the wrist that articulate the distal row of carpal bones and the proximal bases of the five metacarpal bones.. The CMC joint of the thumb or the first CMC joint, also known as the trapeziometacarpal (TMC) joint, differs significantly from the other four CMC joints and is therefore described separately.
