Wrist Injury - Causes, Symptoms, Treatment
Sunday, July 13th, 2008Wrist and metacarpal injuries are more common in contact sports, racquet sports, and gymnastics. The wrist represents one of the most complicated regions of the musculoskeletal anatomy. It is comprised of 15 bones, 27 articular surfaces, and an elaborate system of ligaments that maintain these bones and surfaces in proper relation to one another.
The wrist joint is formed proximally by the distal surface of the radius and ulna and the attached fibrocartillage disc, and distally by the scaphoid, lunate and triquetral bones. The wrist as a region extends from the distal radius and ulna to the base of the metacarpals. The wrist positions and supports the hand and therefore has to combine strength and precision with a wide range of movement with stability.
