Skier’s Thumb: What It Is, Why It Hurts, and How Taping Can Help

Skier’s thumb is a common thumb injury that can significantly affect grip strength, hand function, and confidence during daily activities or sport. While it is often associated with skiing, this injury occurs in many sports and everyday accidents involving a fall or sudden force to the thumb.


Understanding the injury — and knowing when support strategies such as taping are appropriate — is key to a safe and effective recovery.


What Is Skier’s Thumb?


Skier’s thumb refers to an injury of the ulnar collateral ligament (UCL) of the thumb. This ligament is located on the inside of the thumb at the knuckle joint (metacarpophalangeal joint) and plays a critical role in:


  • Thumb stability

  • Pinch strength

  • Grip control


The injury typically occurs when the thumb is forced away from the hand, overstretching or tearing the ligament.


How Does Skier’s Thumb Occur?


Skier’s thumb most commonly occurs with:


  • A fall onto an outstretched hand

  • A ski pole catching the thumb during a fall

  • Ball or contact sports

  • Slips and falls in everyday life


Despite the name, many people who develop Skier’s thumb have never been skiing.


Common Symptoms of Skier’s Thumb


Symptoms may include:


  • Pain on the inside of the thumb

  • Swelling and tenderness around the thumb joint

  • Weakness with gripping or pinching

  • A feeling of instability or “giving way”

  • Difficulty holding objects or performing fine motor tasks


In more severe cases, the thumb may feel noticeably unstable.


Why Proper Management Matters


The thumb UCL is essential for functional hand use. Without appropriate management,

Skier’s thumb can lead to:


  • Ongoing pain

  • Reduced grip strength

  • Difficulty returning to sport or work

  • Long-term thumb instability


Early assessment helps determine whether the injury is mild, moderate, or severe, which guides treatment decisions.


When Is Taping Appropriate for Skier’s Thumb?


Taping may be appropriate:


  • After the acute swelling phase

  • Once serious injury or complete ligament rupture has been ruled out

  • During rehabilitation or return to activity

  • When extra support is needed for sport or daily tasks


Taping should not replace medical assessment, especially if pain, swelling, or instability is significant.


How Taping Can Help


When applied correctly, thumb taping can:


  • Support the injured UCL

  • Limit excessive thumb movement

  • Reduce stress on healing tissue

  • Improve confidence with gripping and pinching


Taping is particularly useful during:


  • Return to sport

  • Work tasks involving gripping

  • Periods of increased thumb demand


It is best used as a short-term support strategy, not a permanent solution.


What You Will Need for Thumb Taping


For the taping technique demonstrated in our video, you will need:


  • Elastic adhesive bandage

  • Rigid sports tape

  • Scissors


Correct tape selection and application are important to ensure adequate support without over-restricting movement.


Important Safety Considerations


⚠️ Important Thumb taping is not suitable for all Skier’s thumb injuries. If you experience:


  • Ongoing instability

  • Severe pain or swelling

  • Difficulty gripping even with support


You should seek assessment from a physiotherapist or doctor. Complete UCL tears may require immobilisation or further medical management.


Remove the tape immediately if you experience numbness, tingling, or increased pain.


Taping Is Only One Part of Recovery


Successful recovery from Skier’s thumb usually involves:


  • Gradual loading of the thumb

  • Strengthening of the hand and thumb muscles

  • Restoring movement and control

  • Progressive return to activity


A physiotherapist can guide this process and advise when support strategies like taping are no longer needed.

Final Thoughts


Skier’s thumb is a common but manageable injury. With proper assessment, load management, and appropriate support strategies such as taping, most people can return to normal hand function and sport safely.


If thumb pain or instability persists, individual physiotherapy guidance can make a significant difference to recovery and long-term function.
