SKIER'S THUMB
Cause and development
What is known as skier's thumb is a common injury of the thumb, occurring above all in winter sports. It is damage to the inner collateral ligament (the ulnar collateral ligament) at the base joint of the thumb – often caused by a fall with the ski pole still in the hand. Skier's thumb typically arises when the thumb is overstretched outwards (away from the index finger) in a fall – frequently because the ski pole stays in the hand and forces the thumb into an unnatural movement. This abrupt force can overstretch the collateral ligament or even tear it completely.
Symptoms
Pain around the base joint of the thumb
The pain frequently occurs immediately after the accident. Gripping or moving the thumb in particular is felt as uncomfortable or severely painful.
Swelling and bruising
The joint often swells visibly and can turn blue or purple – a sign of bleeding into the tissue caused by the injury.
Loss of strength
People affected frequently notice a reduced grip strength. Everyday tasks such as opening a bottle or holding an object can become difficult.
How is skier's thumb diagnosed?
The diagnosis is made by a clinical examination and can be supplemented by imaging such as ultrasound or MRI, in order to establish the extent of the injury precisely.
Treatment options for skier's thumb
Treatment of skier's thumb depends on the severity of the ligament injury. What matters is whether the ulnar collateral ligament is overstretched, partly torn or completely divided – and whether this leaves the base joint of the thumb unstable.
Treatment options
Non-surgical and surgical – we will find the right approach for you
Partial tears or overstretching
Immobilisation in a splint or thumb orthosis, as a rule for 4 to 6 weeks
