Also, bony outgrowths, called osteophytes (also known as “bone spurs”), are formed at the joint margins. [6] The main symptom is pain, particularly with gripping and pinching. [7] [8] This pain is often described as weakness, but true weakness is not a part of this disease. People may also note a change in shape of the thumb.
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 ...
Fractures of the fingers occur when the finger or hands hit a solid object. Fractures are most common at the base of the little finger (boxer's fracture). Nerve injuries occur as a result of trauma, compression or over-stretching. Nerves send impulses to the brain about sensation and also play an important role in finger movement.
Fractures in the joints are often caused by jammed finger injuries, the hand equivalent of a stubbed toe. If a tendon pulls away the bit of bone to which it is attached (an avulsion fracture , shown in the image at the top of the page, and in the Busch fracture images below), that will also lead to a fracture in a joint.
The Bennett fracture is an oblique intraarticular metacarpal fracture dislocation, caused by an axial force directed against the partially flexed metacarpal. This type of compression along the metacarpal bone is often sustained when a person punches a hard object, such as the skull or tibia of an opponent, or a wall. It can also occur as a ...
Injuries to it cause instability and loss of function of the thumb. [1] Acutely this injury is known as the Skier's thumb [ 2 ] or if the result of chronic injury Gamekeeper's thumb . References
Indiana quarterback Kurtis Rourke is set to miss at least one game after he suffered a thumb injury in the team’s blowout win over Nebraska. The No. 16 Hoosiers beat the Cornhuskers 56-7.
The neck of a metacarpal is a common location for a boxer's fracture, but all parts of the metacarpal bone (including head, body and base) are susceptible to fracture. During their lifetime, 2.5% of individuals will experience at least one metacarpal fracture. Bennett's fracture (base of the thumb) is the most common. [4]
