Hypermobility, also known as double-jointedness, describes joints that stretch farther than normal. [2] For example, some hypermobile people can bend their thumbs backwards to their wrists and bend their knee joints backwards, put their leg behind the head or perform other contortionist "tricks".
Ganglia, synovial cyst, [1] Gideon's disease, Olamide's cyst, Bible cyst, Bible bump [2] Cyst on dorsum of left hand close to the wrist: Specialty: Plastic surgery, orthopedic surgery, hand surgery: Symptoms: Small soft bump associated with a joint or tendon sheath [3] Complications: Only with operative treatment: Usual onset: Any age ...
For many decades, the physical mechanism that causes the cracking sound as a result of bending, twisting, or compressing joints was uncertain. Suggested causes included: Cavitation within the joint—small cavities of partial vacuum form in the synovial fluid and then rapidly collapse, producing a sharp sound. [7] [8] Rapid stretching of ...
The sound can be created when two rough surfaces in an organism's body come into contact—for example, in osteoarthritis or rheumatoid arthritis when the cartilage around joints erodes and the surfaces in the joint grind against one another, or when the two fractured surfaces of the broken bones rub together.
Symptoms are pain and tenderness at the radial side of the wrist, fullness or thickening over the thumb side of the wrist, painful radial abduction of the thumb, and difficulty gripping with the affected side of the hand. [2] Pain is made worse by movement of the thumb and wrist, and may radiate to the thumb or the forearm. [2]
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.
Besides the clicking, snapping or triggering, a characteristic Notta nodule is commonly found on the palmar side at the metacarpophalangeal (MCP) joint. [1] This nodule can be found by palpation. Children can also present a thumb which they cannot extend actively due to entrapment of the nodule to the A1 pulley. Some may even present with a ...
Hitchhiker's thumb, also known as distal hyperextensibility of the thumb, is the condition of having a thumb that has a distal phalange that bends backwards in an angle of 90°. This condition is benign (when isolated) and does not cause pain or affect the thumb with the trait negatively.
