Many times, thumb sprains will result from sports injuries or falls. For example, skiing results in many thumb injuries, as does basketball. Or, you may fall and try to catch yourself, bending your thumb in an awkward position. To determine the severity of your injury, visit a hand surgeon as soon as possible. He or she may take x-rays to see if any bones are broken. If a ligament is torn, it may be treatable with a cast or splint.
Sprained Thumb - Symptoms, Causes, Treatment & Taping
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 thumb sprain is simply a tear or stretching of any of the ligaments in the thumb. The thumb consists of the phalanges bones which connect to the metacarpal bone at the base of the thumb. This joint is known as the metacarpophalangeal joint.
A thumb sprain happens when you injure the tissues in your thumb that connect the bones in a joint. These tissues, known as ligaments, keep your bones in place when the joint moves. In your thumb, several ligaments help you grab objects, pinch, and make a fist. A broken bone or a torn ligament may require more long-term treatment. You may have trouble grabbing or pinching objects, or barely be able to move your thumb.
