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 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.
In recent decades, the most successful and common form of arthroplasty is the surgical replacement of a joint or joint surface with a prosthesis. For example, a hip joint that is affected by osteoarthritis may be replaced entirely ( total hip arthroplasty ) with a prosthetic hip.
Arthroplasty (literally "[re-]forming of joint") is an orthopedic surgical procedure where the articular surface of a musculoskeletal joint is replaced, remodeled, or realigned by osteotomy or some other procedure. It is an elective procedure that is done to relieve pain and restore function to the joint after damage by arthritis or some other ...
In human anatomy, the radial (RCL) and ulnar (UCL) collateral ligaments of the metacarpophalangeal joints (MCP) of the hand are the primary stabilisers of the MCP joints. [1] A collateral ligament flanks each MCP joint - one on either side.
The intermetacarpal joints are in the hand formed between the metacarpal bones.The bases of the second, third, fourth and fifth metacarpal bones articulate with one another by small surfaces covered with cartilage.
Carpometacarpal bossing (or metacarpal/carpal bossing) is a small, immovable mass of bone on the back of the wrist. The mass occurs in one of the joints between the carpus and metacarpus of the hand , called the carpometacarpal joints , where a small immovable protuberance [ 1 ] occurs when this joint becomes swollen or bossed.
The posterior carpometacarpal ligament consists of a series of bands on the posterior surface of the carpometacarpal joints. They connect the carpal bones to the bases of the second to fifth metacarpals. The second metacarpal bone is connected to the trapezium, trapezoid, and capitate. The third metacarpal is connected to the capitate.
