Skier’s Thumb

Skier’s thumb

Skier’s thumb, also known as Gamekeeper’s thumb, is an injury to the ulnar collateral ligament (UCL) of the thumb. It’s the most common sport injury of hand. UCL injury makes up 8%-10% of all skiing accidents. Pathomechanism of this condition bases on involuntary abduction and hyperextension of the first digit of the hand.

Patient with skier’s thumb feels pain in case of pincer grip.

Total torn UCL causes pain during pincer grip.

Total torn UCL is called also Stener lesion and it occurs when the aponeurosis of the adductor pollicis muscle becomes interposed between the ruptured ulnar collateral ligament (UCL) of the thumb and its site of insertion at the base of the proximal phalanx. This injury required surgery for treatment.

Mechanism of Stener lesion.

To avoid such complicated and dangerous injury, you should use our hand brace AM-OSN-U-12, dedicated for skier’s thumb. 

Product’s description

Special construction allows to use our brace under ski glove. You can use it prophylactically or as an post-injury thumb immobilizer. The brace’s small size doesn’t immobilize the wrist joint, so you can use it every day.

CODURA

CODURA is extreme durable lamination made of polyamide with polyurethane layer and Teflon finishing. Structure of fabrics and method of milling make the fabric lightweight but very resistant to damages and extreme conditions. External layer is covered by Teflon.
