Sprained thumb
From opening a jar to gripping your phone, a sprained thumb can make even the simplest everyday activities painful and difficult.
What is a sprained thumb?
A sprained thumb happens when the ulnar collateral ligament (UCL), one of the main ligaments that stabilises the base of the thumb, is stretched or torn. This ligament is essential for gripping, pinching and holding objects securely. Thumb sprains most commonly occur after a fall onto an outstretched hand or when the thumb is forced away from the hand. This is particularly common during skiing, where the thumb can become trapped against a ski pole, which is why the injury is often called skier's thumb. Repeated strain during sport can also gradually weaken the ligament over time. Although many thumb sprains are mild, a complete ligament tear or an associated fracture may require more specialised treatment. Having your injury assessed early helps identify the severity of the damage and ensures you receive the most appropriate care.
What Are the Symptoms?
Symptoms vary depending on the severity of the injury but commonly include:
- Pain at the base of the thumb
- Swelling and tenderness around the thumb joint
- Bruising around the thumb
- Difficulty gripping or pinching objects
- Weakness when holding items between the thumb and fingers
- A feeling that the thumb is unstable or gives way
- Reduced movement due to pain
If your thumb feels very unstable or you are unable to grip objects after an injury, it's important to seek medical assessment promptly.
How is it diagnosed?
Your consultant will begin by discussing how your injury happened, your symptoms and how your thumb is affecting your daily activities.
They will then carefully examine your thumb to assess the stability of the ligament, your range of movement and whether there are signs of a complete tear or fracture.
To confirm the diagnosis, we may recommend:
- A detailed medical history
- Physical examination of the thumb
- Assessment of thumb movement and stability
- X-rays to check for an associated fracture
- An ultrasound or MRI scan if further assessment of the ligament is needed
How is it treated?
Your treatment will depend on the severity of your injury, your lifestyle and your recovery goals. Your consultant will explain your options clearly and work with you to develop a treatment plan that's right for you.
Treatment may include:
- A splint or cast to protect the thumb while the ligament heals
- Ice and pain relief to reduce discomfort and swelling
- Hand therapy or physiotherapy to restore strength, movement and function
- Activity modification during the early stages of recovery
- Surgery if the ligament is completely torn or has pulled away from the bone, or if there is an associated fracture

Treatment routes for a Sprained thumb
Many thumb sprains can be treated successfully without surgery.
If the ligament is only partially torn and the joint remains stable, your thumb is usually protected in a splint or cast for around four to six weeks. As healing progresses, rehabilitation focuses on restoring movement, rebuilding strength and helping you return confidently to everyday activities.
Recovery goals after a Sprained thumb
During the first stage of recovery, the focus is on:
Reducing pain and swelling Protecting the injured ligament Allowing the thumb to heal safely Maintaining movement in the surrounding joints
As healing progresses, rehabilitation focuses on:
Restoring thumb movement Improving grip and pinch strength Increasing confidence using your hand Returning to normal daily activities
The final stage of rehabilitation aims to:
Build strength for work, hobbies and sport Improve hand function and coordination Return safely to higher levels of activity Reduce the risk of future injury

Sprained Thumb FAQs
A mild thumb sprain may recover within four to six weeks. More severe injuries, particularly those requiring surgery, can take several months to regain full strength and function.
Not always. Many thumb sprains heal successfully with a splint or cast and rehabilitation. Surgery is generally recommended for complete ligament tears, unstable injuries or when the ligament has pulled away from the bone.
You may still be able to use your hand for light activities, but gripping and pinching are often painful. It's important to avoid activities that place further strain on the injured ligament until your consultant advises it is safe.
This depends on the severity of your injury and the demands of your sport. Some people return after six to eight weeks, while others may need longer following surgery. Your consultant and therapist will advise when it is safe to return based on your recovery and hand strength.
