Wrist brace AM-OSN-U-12

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.

Additionally, the thumb brace is equipped with metal splint immobilizing the thumb.

The brace is very easy to putting on and Velcro straps provide excellent fitting and compression. You can also cut the excessive Velcro strap off.

Metal splint stabilizes the metacarpophalangeal joint and reduces the risk of sudden thumb abduction and hyperextension.

STIFFENINGS

Profiled aluminum stays

These are splints and orthopedic stays of various thickness and width, which are made of various types of aluminum alloys. All these splints and stays, before mounting to a given orthosis, have been pre-profiled, which allows for fitting the product to the body of a specific patient. However, for the correct operation of the device, they should be precisely bent to the patient's body by an orthopedist, physiotherapist or orthopedist technician. Only this action guarantees the proper protection and support of the patient's body.
