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 ...
Gamekeeper's thumb, also known as skier's thumb, is characterised by a diminished ability to grasp or pinch with the thumb due to damage to the ulnar collateral ligament (UCL). [4] Gamekeeper's thumb can be caused by acute injury or chronic overuse, often arousing from a fall where the hand is extended that leads to forceful separation of the ...
The ulnar collateral ligament of the thumb runs along the ulnar side of the metacarpo-phalangeal joint of the thumb. The ulnar collateral ligament is an important stabilizer of the thumb. It is on the radial side of the wrist, but on the ulnar side of the thumb.
[7] [8] Irradiation of the cervical spine may also evoke it as an early delayed radiation injury, which occurs within 4 months of radiation therapy. [citation needed] Delayed onset Lhermitte's sign has been reported following head and/or neck trauma.
Froment sign is the flexion of the interphalangeal joint of the thumb rather than adduction of the entire thumb. Note that the flexor pollicis longus is nearly always innervated by the anterior interosseous branch of the median nerve. Simultaneous hyperextension of the thumb MCP joint is indicative of ulnar nerve compromise. This is also known ...
The Big Air freestyle skiing competitor at the Beijing Winter Olympics might want to leave this in a safer place next time.
The body of a skier reported overdue in Mount Rainier National Park in Washington state around three weeks ago was recovered at the base of a waterfall Saturday, park officials said Tuesday.
Anterior interosseous syndrome is a medical condition in which damage to the anterior interosseous nerve (AIN), a distal motor and sensory branch of the median nerve, classically with severe weakness of the pincer movement of the thumb and index finger, and can cause transient pain in the wrist (the terminal, sensory branch of the AIN innervates the bones of the carpal tunnel).
