Skiers Thumb: Understanding and Managing the Injury

What is Skiers Thumb?

Skiers Thumb, medically known as Ulnar Collateral Ligament (UCL) injury, is a common condition among skiers, resulting from the stretching or tearing of the ligament at the thumb's base. Skier’s thumb is the second most common ski-related injury after knee injury. It's a condition that not only affects skiers but can also occur to anyone where there is an extreme force applied to the thumb in abduction and extension or small repetitive force. This type of injury is also seen in other sports, such as hockey or basketball.

Types of Skiers Thumb

  1. Partial Tear: A partial tear in Skiers Thumb involves the stretching but not complete severing of the ulnar collateral ligament (UCL) at the thumb's base. This injury typically results from a forceful outward bending of the thumb, often seen in skiing falls. Symptoms include pain at the thumb's base, especially when pinching or gripping, mild to moderate swelling, and some degree of joint instability. While the ligament remains partially intact, its ability to stabilize the thumb joint is compromised.
  2. Complete Tear: A complete tear of the UCL in Skiers Thumb is a more severe injury where the ligament is fully torn. This often occurs due to a more significant impact or fall, resulting in immediate and severe pain, pronounced swelling, bruising, and a noticeable instability or laxity in the thumb joint. The thumb may also exhibit a decreased range of motion, particularly in pinching movements. Treatment for a complete tear is more intensive.

Causes and Risk Factors

  • Direct Impact: Falling on an outstretched hand while holding a ski pole.

Direct impact causing Skiers Thumb usually occurs when a skier falls with an outstretched hand while gripping a ski pole. The force of landing drives the pole into the base of the thumb, exerting extreme pressure on the ulnar collateral ligament (UCL). This impact can cause stretching or tearing of the ligament, resulting in Skiers Thumb. The severity of the injury depends on the force of the fall and the thumb's position during impact.

  • Pre-Existing Conditions: Previous thumb injuries can increase the risk.

Individuals with pre-existing thumb injuries are at a higher risk of developing Skiers Thumb. Previous injuries can weaken the ulnar collateral ligament or cause scar tissue formation, reducing its flexibility and strength. As a result, even a minor impact or stress on the thumb can lead to a new injury or aggravate an existing one. People with a history of thumb ligament sprains or injuries should take extra precautions, such as using supportive thumb braces while engaging in activities that put stress on the thumb, like skiing.

  • Improper Ski Pole Handling: Not releasing the pole during a fall can lead to direct trauma.

Improper handling of ski poles significantly contributes to the risk of Skiers Thumb. When a skier does not release the pole during a fall, the pole acts as a lever against the hand and thumb, creating a fulcrum that forcefully pushes the thumb outward. This action can strain or tear the UCL. Proper ski pole handling techniques, such as learning to instinctively let go of the poles during a fall, can greatly reduce the risk of thumb injuries. Skiers should be educated on the correct grip and release techniques as a part of their skiing lessons to prevent such injuries.

Symptoms to Watch For

  • Pain and swelling at the base of the thumb. The pain, often sharp and immediate upon injury, intensifies during activities that put pressure on the thumb, like gripping.
  • Bruising or discolouration. Typically appearing a day or so after the injury, the bruising can range from light purple to deep blue, indicating the severity of the impact and the extent of soft tissue damage.
  • Limited thumb movement or weakness in grip. This limitation is pronounced in activities requiring thumb opposition or pinching. The severity of movement restriction often correlates with the extent of ligament damage


A healthcare provider will typically conduct a physical examination and may order imaging tests like X-rays or MRI to assess the extent of the injury.

Treatment Plan

The key to effective treatment lies in early intervention and appropriate support.

Initial Care (R.I.C.E. Method)

  1. Rest: Avoid activities that exacerbate the pain.
  2. Ice: Apply ice packs to reduce swelling.
  3. Compression: Use a bandage to support the thumb.

Using A Thumb Brace

Our specialized thumb brace offers support and stability, crucial for the healing process. It's designed to:

  • Immobilize the thumb to promote healing.
  • Provide adjustable compression to manage swelling.
  • Allow for a range of motion in the other fingers.


1. Physical Therapy: Once healing progresses, physical therapy can help restore strength and range of motion.

A tailored physical therapy program focuses on restoring the thumb's strength, flexibility, and range of motion. Therapists use various techniques such as manual therapy, ultrasound, or heat treatment to reduce stiffness and pain.

Thumb Flexion/Extension

  1. Place your forearm and hand on a table with your thumb pointing up.
  2. Bend your thumb downward and across your palm so that your thumb touches the base of your little finger. Hold that position for about 6 seconds. Then straighten your thumb.
  3. Repeat 8 to 12 times.
  4. Switch hands, and repeat steps 1 through 3.

Thumb Active Range of Motion

  1. Extend your arm with the palm facing down.
  2. Move your thumb away as far as you can
  3. Hold for 5 seconds, then relax thumb
  4. Rotate hand so palm is facing up
  5. Move your thumb away as far as you can
  6. Hold for 5 seconds, then relax thumb
  7. Repeat 5 times

2. Strengthening Exercises: Gradual strengthening exercises are vital for recovery.

Gradual strengthening exercises are essential for a complete recovery from Skiers Thumb. These exercises aim to rebuild the strength and stability of the thumb without overstraining the healing ligament. Initial exercises may include gentle thumb flexion and extension movements, progressing to more challenging activities like gripping and pinching exercises. Using resistance bands or squeezing soft balls can also be effective. It's important to increase the intensity of these exercises gradually, as per the guidance of a healthcare professional, to avoid re-injury.

Thumb Opposition Exercise

  1. Start with your hand open and fingers straight.
  2. Touch the tip of your thumb to the tip of each finger on the same hand, one at a time, creating a gentle pinching motion. Make sure to move through the full range of motion, touching each fingertip.
  3. Do this 10-15 times for each finger, and repeat for 2-3 sets. This exercise helps to strengthen the muscles involved in thumb opposition, enhancing grip and dexterity.

Grip Strengthening

  1. Use a soft stress ball or a similar resistance tool.
  2. Hold the ball in your palm and squeeze it using all your fingers, including your thumb. Apply pressure evenly and hold the squeeze for a few seconds.
  3. Perform 10-15 squeezes, then rest. Repeat for 2-3 sets. This exercise strengthens the entire hand, particularly focusing on the thumb's ability to apply pressure, which is crucial for tasks that involve gripping.

Prevention Tips

1. Proper Ski Pole Technique: Learn to drop the ski pole during falls.

Mastering the proper ski pole technique is vital for preventing injuries like Skiers Thumb. One key aspect is learning to drop the ski pole during falls. This technique involves loosening the grip on the poles when a fall is imminent, thereby reducing the risk of the pole exerting force on the thumb, which can lead to ligament damage. Skiers should practice this in a controlled environment to develop an instinctive response. Additionally, correct pole handling, such as not over-gripping and maintaining a natural wrist position, is crucial to minimize stress on the thumb during skiing.

2. Strengthening Exercises: Regular exercises to strengthen the hand and thumb.

Regular exercises to strengthen the hand and thumb are essential for both prevention and recovery from Skiers Thumb. These exercises should focus on improving the strength and flexibility of the thumb, as well as the entire hand. Techniques include squeezing a stress ball, performing thumb opposition exercises (touching the thumb to each finger tip), and using resistance bands to enhance thumb flexion and extension. Consistent practice of these exercises builds resilience in the thumb ligaments and muscles, reducing the risk of injury during activities that put stress on the thumb, like skiing.

3. Protective Gear: Consider wearing thumb guards or supportive gloves.

Using protective gear such as thumb guards or supportive gloves is an effective way to prevent Skiers Thumb. Thumb guards provide a shield around the thumb, absorbing and distributing the force away from the ulnar collateral ligament during a fall or impact. Supportive gloves, on the other hand, offer a more integrated solution, combining warmth and protection while retaining flexibility and grip. They help in stabilizing the thumb, reducing the likelihood of hyperextension or abnormal movements that can lead to injury.


In conclusion, Skiers Thumb is a significant injury that requires attention and proper care. Understanding its causes and symptoms is the first step towards effective treatment and prevention. Utilizing physical therapy, tailored strengthening exercises, and appropriate protective gear like thumb braces can vastly improve recovery outcomes. Remember, prevention through proper ski pole technique and awareness is key. Whether you're a seasoned skier or a beginner, being informed and prepared can help you enjoy the slopes safely. Stay vigilant and proactive about your thumb health to ensure a pain-free and enjoyable skiing experience.
