Thumb sprains are so common in skiers that they are often called “skier’s thumb.” But any sport can cause a sprained thumb, as they often occur from falling. When you fall during sports, your natural reaction is to catch yourself, which puts you at risk for stretching or tearing the main ligament in the thumb. Depending upon the severity of the tear, the proper treatment prescribed by Dr. Nadel may involve a bandage, splint or cast coupled with icing. In severe cases, where the ligament has been badly torn, Dr. Nadel may need to perform surgery to reconnect the ligament to the bone properly. Surgeries are performed at West Hills Hospital.
