How does it happen?

It is one of those injuries often seen in skiers, resulting from falling on an outstretched thumb when holding onto a ski pole. Other common causes include bike or motorcycle falls, whereby you land on your hand with your thumb stuck behind its bar, or contact sports like football and basketball, where it might jam into an uncomfortable position.

Although a skier’s thumb is typically associated with a single traumatic event, repetitive stress on the UCL can cause similar damage.

Signs you may have skier’s thumb

If you’ve forced bent your finger in an abnormal direction, look for any bruising or swelling around its area. Another strong indicator of game keeper's thumb is experiencing pain at its base whenever you touch or move it around.

If you have difficulty gripping everyday items with your affected hand, i.e. pens, doorknobs, etc., anything held between index fingers and thumbs, like turning the doorknob using only fingertips—this may indicate damage to UCL. Severe cases will cause the affected finger to bend more than usual.

Skier's Thumb treatment options

If you think you could be having a skier’s thumb, then make sure you see a hand therapist for the proper diagnosis and treatment of this condition. Non-surgical treatment is usually recommended when the UCL tear is not complete. This may involve immobilising the thumb using a splint or cast for four to six weeks as it allows the ligament to heal. Your hand therapist might give physical therapy exercises to regain mobility and enhance strength in your thumb after this period.
