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.
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.
With gamekeeper's thumb, where the ulnar collateral ligament (UCL) is damaged, thumb functional abilities may be diminished. [4] For fingertip deformities, such as in mallet finger, pain and fingernail disruption may also be observed. [13] Rheumatoid arthritis of the hands may cause hand deformities.
[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. [11] Osteoarthritis is the most common form of arthritis, affecting about 237 million people or 3.3% of the world's population as of 2015. [4] [12] It becomes more common as people ...
Symptoms of Bennett fracture are instability of the CMC joint of the thumb, accompanied by pain and weakness of the pinch grasp. Characteristic signs include pain, swelling, and ecchymosis around the base of the thumb and thenar eminence, and especially over the CMC joint of the thumb. Physical examination demonstrates instability of the CMC ...

The peripheral metacarpals (those of the thumb and little finger) form the sides of the cup of the palmar gutter and as they are brought together they deepen this concavity. The index metacarpal is the most firmly fixed, while the thumb metacarpal articulates with the trapezium and acts independently from the others.
