Carpal Tunnel Syndrome
Carpal Tunnel Syndrome is a common painful disorder of the wrist and hand, caused by compression on the median nerve between the inelastic carpal ligament and other structures within the carpal tunnel. It is often seen in cumulative trauma to the wrist. Symptoms may result from trauma, synovitis, or tumor or may develop with rheumatoid arthritis, amyloidosis, acromegaly, or diabetes. The median nerve innervates the palm and the radial side of the hand; compression of the nerve causes weakness, pain with opposition of the thumb, and burning, tingling, or aching, sometimes radiating to the forearm and shoulder joint.
