A gamekeeper's thumb, also called a skier's thumb, is an injury to one of the important ligaments at the base of the thumb joint. The injury involves the ulnar collateral ligament UCLa band of tough, fibrous tissue that connects the bones at the base of the thumb. This ligament prevents the thumb from pointing too far away from the hand.
Articles in the December issue discuss various health issues affecting school-aged children, including acne, eczema and growth disorders. Volume 39, No. It is often misdiagnosed, which can lead to chronic instability.

The breaking of the unlar collateral ligament first metacarpophalangeal joint is one of the most frequent injuries sustained from sporting activities, and can result in pain and instability in the thumb. This injury is caused by a force that pushes the thumb away from the fingers, developing in pain, bruising and swelling in the area, and can be caused from a single force or maybe due to repeated forces. The radial collateral ligament is found on the other side of the thumb.
The injury may also be the result of falling on an outstretched thumb or catching a ball with an outstretched thumb. The injury may be relatively mild or complicated by an avulsion fracture of the proximal phalanx at the insertion of the UCL or a Stener lesion, present when both the proper collateral ligament and the collateral ligament are ruptured. Prior to initiating any treatment protocol, a careful examination of the thumb by a trained medical specialist is necessary to determine the extent of the injury and the appropriate treatment.
Ligaments are fibrous bands of connective tissue made of collagen, which join bone to bone. Ligaments provide stability and limit excessive motion of the joint. In the thumb, the joint is the hinge that allows the finger to bend.
Skier's thumb, also known as Gamekeeper's thumb, is an injury to the ulnar collateral ligament UCLwhich is located in the metacarpophalangeal MCP joint where the thumb meets the hand. The purpose of the UCL is to keep the thumb stable in order to pinch objects. An injury to the UCL can be painful and result in a loss of function and pinch strength.
Gamekeeper's thumb also known as skier's thumb or UCL tear is a type of injury to the ulnar collateral ligament UCL of the thumb. It also occurs among people who sustain a fall onto an outstretched hand, frequently skiers. Symptoms of gamekeeper's thumb are instability of the MCP joint of the thumb, accompanied by pain and weakness of the pinch grasp.
NCBI Bookshelf. The metacarpophalangeal MCP joint of the thumb plays an important role in normal hand gripping and pinching. The radial and ulnar collateral ligaments UCL are the primary stabilizers to varus and valgus stress on this joint.
