This type of injury occurs more often that most people would imagine. This type of injury is commonly referred to as the gamekeeper’s thumb or skier’s thumb. A torn ligament in the thumb can temporarily cause your hand to lose the ability to pinch and grasp objects. When there is a complete tear in the ligaments of the thumb, the metacarpophalangeal joint, or MCP joint is affected. This joint becomes weak and unstable, which causes the thumb to bend backwards.

Hand ligaments. The collateral ligaments of the hand are located on each side of all the fingers and thumb joints to limit the lateral movement of the fingers. The volar plate is the strongest ligament surrounding only the middle inter-phalangeal joints. It prevents the hyperextension of the fingers.

The thumb metacarpal can bend and extend the thumb, move the thumb away from and toward the hand, and spin the thumb on the trapezium. Two very important ligaments are the dorsoradial and the volar beak ligaments. The abductor pollicis longus and brevis help move the thumb away from the hand. Ligaments are tough bands of tissue that connect bones together. Two important structures, called collateral ligaments, are found on either side of each finger and thumb joint.The function of the collateral ligaments is to prevent abnormal sideways bending of each joint.
