Sprained thumb

Overview

A sprained thumb occurs when a ligament is overextended or torn while severely stressing a joint. Common causes include skiing injury or overextension when playing racket sports, such as tennis.

Symptoms

Thumb weakness, swelling, bruising, and pain are symptoms.

Treatments

Treatment includes immobilizing the joint with a splint or cast and icing to reduce swelling. Surgery may be needed if the ligament is completely torn.
