Arthroplasty surgery for TMC OA removes part or all of the trapezium. [27] Surgery may also support the metacarpal by reconstructing a ligament using a tendon graft or weave. Surgery may also place something in the space where the trapeziometacarpal joint was, either a tendon wrapped up into a ball or a prosthesis.
The trapezium is distinguished by a deep groove on its anterior surface. It is situated at the radial side of the carpus, between the scaphoid and the first metacarpal bone (the metacarpal bone of the thumb). It is homologous with the first distal carpal of reptiles and amphibians.
This bone may be present in approximately 2–21% of the general population and is usually asymptomatic. [18] [19] [20] When it is symptomatic, surgery may be necessary. The Geist classification divides the accessory navicular bones into three types. [20] Type 1: An os tibiale externum is a 2–3 mm sesamoid bone in the distal posterior ...
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.
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.
In the case of the Bennett fracture, the proximal metacarpal fragment remains attached to the anterior oblique ligament, which in turn is attached to the tubercle of the trapezium bone of the CMC joint. This ligamentous attachment ensures that the proximal fragment remains in its correct anatomical position. [citation needed]
Memphis Grizzlies guard Desmond Bane had surgery Tuesday on his right big toe after initially breaking a bone during a game Nov. 11 against Minnesota. The Grizzlies announced the procedure Tuesday ...
This is due to the bone being in a fairly protected position. Distally, it forms a stable, relatively immobile joint with the second metacarpal, radially and proximally it forms strong ligaments with the trapezium and the capitate ulnarly, scaphoid respectively. However, injury can occur through axial force applied to the second metacarpal base.
