Extensor Tendon Injury
Extensor tendons, located on the back of the hand and fingers, allow you to straighten your fingers and thumb. Extensor tendons are just under the skin, directly on the bone, on the back of the hands and fingers. Because of their location, even a minor cut can easily injure them. Jamming a finger may cause these thin tendons to rip apart from their attachment to the bone.
Common types of extensor tendon injuries include
- Mallet Finger
- Boutonniere Deformity
Extensor tendon injuries may result in scar tissue that causes the tendon to adhere to nearby bone, limiting the movement of the tendon. The scar tissue that forms may prevent full finger bending and straightening. Treatment for extensor tendon injuries varies from conservative treatment to tendon repair surgery. Our hand doctors at Emory will discuss the best treatment option for your injury.
