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.
The healthy bone and cartilage are taken from areas of low stress in the joint so as to prevent weakening the joint. [11] Depending on the severity and overall size of the damage multiple plugs or dowels may be required to adequately repair the joint, which becomes difficult for osteochondral autografts. The clinical results may deteriorate ...
The extensor tendon sheaths on the back of the wrist. De Quervain syndrome involves noninflammatory thickening of the tendons and the synovial sheaths that the tendons run through. The two tendons concerned are those of the extensor pollicis brevis and abductor pollicis longus muscles. These two muscles run side by side and function to bring ...
The CMC joint of the thumb allows a wide range of motion while maintaining stability for grasp and pinch. [ citation needed ] With this in mind, failure to properly recognize and treat the Bennett fracture will not only result in an unstable, painful, arthritic CMC joint with diminished range of motion: it will also result in a hand with ...
Gamekeeper's thumb and skier's thumb are two similar conditions, both of which involve insufficiency of the ulnar collateral ligament (UCL) of the thumb. The chief difference between these two conditions is that skier's thumb is generally considered to be an acute condition acquired after a fall or similar abduction injury to the metacarpophalangeal (MCP) joint of the thumb, whereas gamekeeper ...
Despite this low number of MSC's, isolated bone marrow nucleated cells implanted into degenerated human peripheral joints have shown some promise for joint repair. [16] As the number of MSC's that can be isolated from bone marrow is fairly limited, most research in cartilage regeneration has focused on the use of culture-expanded cells.
Prolotherapy involves the injection of an irritant solution into a joint space, [22] weakened ligament, or tendon insertion to relieve pain. [ 7 ] Most commonly, hyperosmolar dextrose (a sugar) is the solution used; [ 23 ] glycerine , [ 20 ] lidocaine (a commonly used local anesthetic ), [ 24 ] phenol , [ 20 ] and sodium morrhuate (a derivative ...
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 ...
