How do Skiers thumb injuries occur?

        

 

 

The term “Skier’s thumb” refers to a rupture of the Ulnar Collateral ligament of the Thumb M.C.P. Joint. ( More Information – Anatomy).
It commonly occurs during a fall while skiing.

           

The thumb may get caught around the ski pole straps or the thumb may catch in the snow and be deviated ( Abducted) away from the fingers tearing the ligament. The ligament may also tear from a simple fall on the outstretched hand or during sport such as Rugby.

It also occurs occasionally while driving if the wheels suddenly twist such as hitting the kerb. 

          

If the wheel twists suddenly the right thumb may be injured.

Another name for Skier’s thumbs is “Gamekeeper ‘s thumb” initially described in Scottish Gamekeeper’s. The rabbits were killed by breaking their necks with the thumb & index finger wrapped around the rabbit’s neck and traction applied to the body by the other hand. (Rather gruesome! ) but over time the ulnar collateral ligaments stretched and eventually ruptured.
