Sprained Thumb

What is a sprained thumb?

When the thumb is bent out of it's normal range of movement (usually backwards), damage occurs to the ligaments supporting the joint at the bottom of the thumb (metacarpo-phalangeal joint).

It is common in skiing, contact sports and ball sports such as basketball and netball.

What are the symptoms of a sprained thumb?

• Pain when the thumb is bent backwards.
• Pain in the web of the thumb when it is moved.
• Swelling over the joint at the bottom of the thumb.
• Laxity and instability in the joint.

If there is a lot of laxity and instability in the joint a total rupture may be suspected in which case the injury requires surgery.

Useful Products:

• Zinc Oxide Tape - a good taping technique can help the joint to rest by providing support and preventing further damage.
• Cold Therapy - apply ice or cold therapy to help reduce pain and swelling.
