Thumb Sprains: Causes, Types, and Treatment

A thumb sprain is an injury to the ligament that connects the bones to the joint, often caused by a fall or a sports-related injury. In a sprain, the thumb is typically bent beyond its normal range of motion, which can result in swelling, pain, and bruising at the affected area.

Common Thumb Sprains

Two ligaments are commonly injured during a thumb sprain:

  • Ulnar Collateral Ligament (UCL): Located on the medial side of the thumb, the ulnar collateral ligament is the most commonly injured in thumb sprains. It is often associated with a condition known as “skier’s thumb”, as it is frequently seen in skiing accidents.
  • Radial Collateral Ligament (RCL): This ligament is located on the lateral side of the thumb and is less commonly injured compared to the UCL.
Treatment for Thumb Sprains

If you suspect a thumb sprain, it is essential to see one of the trained physicians at South Florida Hand and Orthopaedic Center. The doctor will perform an x-ray to rule out any bone fractures in the hand or thumb. Following the imaging, a physical examination will help assess the severity of the sprain.

Both ulnar and radial collateral ligament sprains are typically treated with a cast or splint to immobilize the thumb and promote healing. If the injury is severe or does not respond to conservative treatment, further intervention may be necessary.
