Thumb fracture

Your thumb plays a part in almost everything your hand does, from holding a cup to fastening a button. When it’s broken, getting the bones back into the right position can make a significant difference to how well your hand works once it has healed.

What is a thumb fracture?

A thumb fracture is a break in one of the bones that forms your thumb or connects it to your hand. One bone runs through your palm to the base of the thumb. This is called the first metacarpal. Above it are two smaller bones: the lower thumb bone (proximal phalanx) and the upper thumb bone (distal phalanx). Any of these bones can break. Fractures that affect a joint need particular care because an uneven joint surface can make the thumb stiff and increase the risk of thumb osteoarthritis in later life. Some breaks happen at the base of the first metacarpal and extend into the joint. These are called Bennett fractures. If the bone has broken into several pieces, it’s called a Rolando fracture. Both can be harder to keep in place while they heal.

What causes a thumb fracture?

A thumb can break when you land on it during a fall or when it’s forced backwards while catching a ball. A hard blow or forceful twist may cause the same injury.

 

Thumb fractures are often seen in contact sports and activities where the hand can become caught or twisted. Protective gloves or supportive taping may reduce the risk in some sports, but they can’t prevent every injury.

 

What are the symptoms of a thumb fracture?

A broken thumb is usually painful straight away. Swelling may develop quickly and spread into the hand.

 

Other signs can include:

  • Tenderness over the injured bone
  • Bruising around the thumb
  • Difficulty gripping or pinching
  • A change in the thumb’s shape
  • Being unable to move it normally

 

A sprained thumb can cause similar symptoms. An assessment can show if you’ve damaged a bone or one of the strong bands of tissue that supports the thumb.

 

How is a thumb fracture diagnosed?

It’s best to seek medical advice promptly, particularly if the thumb looks out of position or you can’t move it. Delaying treatment can make it harder to realign the bones once swelling and healing have begun.

 

Your specialist will examine the thumb and ask how the injury happened. X-rays can show where the bone has broken, whether any pieces have moved and whether the break reaches a joint.

 

Occasionally, another scan may be needed for a clearer picture of a complicated break.

 

How is a thumb fracture treated?

Treatment depends on where the bone has broken and if the pieces are still in the right position. A stable break may only need protection while it heals. If the pieces have shifted or the break reaches the joint, they may need to be moved back into place.

 

The aim is to help your thumb heal in a position that gives you comfortable movement and a strong grip.

Treatment routes for Thumb fracture

Your specialist will explain what your X-rays show and why a particular approach is recommended. You may have further scans during treatment to check that the bone hasn’t moved.

A stable fracture can often be treated with a splint or cast that supports both the thumb and wrist. You’ll usually wear this for several weeks while the bone heals.

 

Further X-rays may be taken at this time. If the bone begins to move out of place, your treatment plan may need to change.

 

Once healing is secure, exercises can help ease stiffness and restore movement. A hand therapist may guide you if you need extra help getting your thumb moving again.

 

What to expect as your thumb heals

During this time:

Wear your cast or splint as advised Keep your hand raised if it’s swollen Move your free fingers to prevent stiffness Avoid gripping or lifting with the injured hand Once the bone is healing well, your specialist or hand therapist will help you reintroduce movement and gradually build strength. Follow-up X-rays will guide when you can return to manual work or sport.
