Mallet finger is a common hand injury that makes it impossible to straighten the fingertip. The end of the finger stays bent because the tendon that lifts it has been damaged. Although it may look simple, this type of injury can interfere with everyday activities if not treated properly.
What is Mallet Finger?
Mallet finger, sometimes called baseball finger, occurs when the tendon on the back of the finger tears or stretches. This tendon connects to the bone at the fingertip and allows it to extend. When it is injured, the fingertip drops down while the rest of the finger can still move normally.
Mallet finger usually affects the joint closest to the nail. The injury can range from a minor tendon strain to a small piece of bone pulling away where the tendon attaches.
Common Causes of Mallet Finger
A mallet finger injury happens when something strikes the fingertip or bends it forcefully. It is common in sports like baseball, basketball, and volleyball, but can also occur during simple daily activities. Some examples include:
A ball hitting the tip of your finger
Jamming your finger against a hard object
Catching your finger while making a bed or closing a drawer
Anyone can develop mallet finger, regardless of age or activity level.
Signs and Symptoms
The most noticeable sign is a fingertip that droops and cannot straighten on its own. Other symptoms include:
Pain and swelling around the end of the finger
Redness or bruising
Tenderness over the top joint
Difficulty extending the finger
If you notice these symptoms after an injury, seek medical attention as soon as possible. Early treatment helps prevent stiffness or permanent deformity.
Treatment and Recovery
Most mallet finger injuries heal with a custom splint that keeps the fingertip straight. The splint allows the tendon to rest and reattach to the bone. It is usually worn for six to eight weeks without interruption. During this time, keeping the finger extended is critical for proper healing.
Surgery may be needed if the tendon has pulled off a large piece of bone or if the joint is out of alignment. A hand specialist can determine the best treatment based on the type and severity of the injury.
