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.
Osteoarthritis of the carpometacarpal joints is a type of joint disease that results from breakdown of joint cartilage and underlying bone. [13] When it affects the thumb it is termed trapeziometacarpal osteoarthritis. Carpometacarpal bossing is the presence of a small immovable protuberance over the joint. [14]
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 age. [1] Among those over 60 years old, about 10% of males and 18% of females are affected. [2] Osteoarthritis is the cause of about 2% of years lived with disability. [12]
Arthroscopy allows patients to recover from the surgery in a matter of days, rather than the weeks to months required by conventional, "open" surgery; it is a very popular technique. Knee arthroscopy is one of the most common operations performed by orthopedic surgeons today, and is often combined with meniscectomy or chondroplasty.
Post-traumatic osteoarthritis is the most common variation of post-traumatic arthritis. [3] Between 20 and 50% [4] of all osteoarthritis cases are preceded by post-traumatic arthritis. Patients having post-traumatic osteoarthritis are usually younger than osteoarthritis patients without any previous physical injuries. [5]
Historicopous, trigger digit, trigger thumb, [1] stenosing tenosynovitis [1] An example of trigger finger affecting the ring finger: Specialty: Hand surgery, orthopedic surgery, and plastic surgery: Symptoms: Catching or locking of the involved finger, pain [2] [3] Usual onset: 50s to 60s years old [2] Risk factors: Generally idiopathic ...
Half of nonosteoporotic patients will develop post-traumatic arthritis, specifically limited radial deviation and wrist flexion. This arthritis can worsen over time. [ 6 ] Displaced fractures of the ulnar styloid base associated with a distal radius fracture result in instability of the DRUJ and resulting loss of forearm rotation.
