A thumb sprain occurs when the thumb is bent out of its normal range of movement, usually backward. It is common in skiing, rugby, and basketball. If a sprained thumb is not treated properly it can recur and be a long term weakness.
A sprain is an injury to a ligament, which is a soft tissue that connects bones to each other at joints. The most common ligament to be injured in the thumb is the ulnar collateral ligament. This helps connect the thumb to the hand on the side near the index finger.
A sprained thumb is a relatively common condition characterized by damage or tearing of the connective tissue such as ligaments, cartilage and joint capsule of the thumb. The thumb comprises of 2 small bones known as phalanges. These small bones join to each other at the IP joint Interphalangeal Joint and to the bone at the thumb side of the palm 1st metacarpal at the MCP joint Metacarpophalangeal Joint forming 2 joints for the thumb figure 1.

A sprained thumb occurs when the ligaments that support the thumb stretch beyond their limits or tear. This usually happens when a strong force bends the thumb backwards, away from the palm of the hand. The most common way for this to occur is by falling onto an outstretched hand. A tear to this ligament can be painful and may make your thumb feel unstable.
The thumb is at risk for a number of injuries including a sprained thumb, because of the role of the thumb in gripping and holding sports implements in sports as well as its location in the hand. One of the more common injuries to the thumb is an injury to the ulnar collateral ligament ligament on the inside of the thumb at the proximal or first joint. The thumb is unique from the fingers in its anatomical structure. While the fingers have three phalanges small bones and two joints proximal and distal interphalangeal jointsthe thumb only has two phalanges and one interphalangeal joint.
