Skier’s thumb

Skier’s thumb, also known as sprained thumb, refers to an injury that occurs due to the tearing of one of the ligaments of the thumb. Ligaments help in supporting the joint and connecting the bone of the hand to the thumb. Ligaments are tough bands that secure the placement of the bone and keep them aligned in a normal state while making movement. A skier’s thumb injury will take place if the thumb is forced to move beyond its normal limitation due to an accident or fall. The injury is known as a skier’s thumb as skiers tend to typically fall on their thumbs while holding on to their ski poles.

A person with a skier’s thumb may experience pain, bruising and swelling around the thumb. The person may also have difficulty moving the affected thumb and holding objects.

The doctor will recommend resting your thumb, applying cold compresses, elevating, a thumb splint and NSAIDs. In case of a completely torn ligament, surgery may be required to repair it.
