What Causes Mallet Finger? Everything You Need to Know

What Is Mallet Finger?

Mallet finger is a common hand injury that occurs when the extensor tendon at the tip of the finger becomes torn or damaged. In some cases, the injury may also pull a small piece of bone away from the fingertip.

As a result, the fingertip droops downward and cannot be fully straightened. Although the injury may seem minor at first, it can affect hand function if left untreated.

How Does Mallet Finger Happen?

Many patients ask, “How does mallet finger happen?”

Typically, mallet finger occurs when the tip of an outstretched finger is struck by an object. Consequently, the finger bends farther than it should, causing damage to the tendon that straightens the fingertip.

Common causes include:

  • Catching a ball during sports
  • Jamming a finger while playing basketball, baseball, or volleyball
  • Workplace injuries
  • Falls
  • Household accidents

Although athletes frequently experience this injury, mallet finger can affect people of all ages and activity levels.

What Does a Mallet Finger Look Like?

One of the most noticeable signs of mallet finger is a fingertip that droops downward. Because the tendon can no longer straighten the joint properly, patients often find that they cannot fully extend the end of the finger.

In addition, symptoms may include:

  • A bent or drooping fingertip
  • Difficulty straightening the end joint
  • Pain or tenderness
  • Swelling
  • Bruising around the joint

At first, the deformity may appear subtle. However, it often becomes more noticeable as swelling decreases.

Can Mallet Finger Heal on Its Own?

Patients often ask, “Can mallet finger heal on its own?” or “Does mallet finger heal on its own?”

Unfortunately, the answer is usually no. While pain and swelling may improve over time, the damaged tendon often does not heal correctly without treatment. Therefore, it is important to seek medical evaluation as soon as possible.

Without proper treatment, patients may develop:

  • Permanent drooping of the fingertip
  • Joint stiffness
  • Weakness
  • Reduced hand function

Fortunately, early treatment can help improve healing and reduce the risk of long-term complications.

How Is Mallet Finger Treated?

Treatment depends on the severity of the injury and whether a fracture is present. In many cases, non-surgical treatment is highly effective.

Most patients wear a splint that keeps the fingertip straight for several weeks. During this time, it is important to follow your physician’s instructions carefully. Even a brief period of finger bending can interrupt healing and delay recovery.

In some situations, surgery may be recommended. For example, surgical treatment may be necessary when:

  • A large bone fragment is involved
  • The joint is unstable
  • Splinting is unsuccessful
  • The injury is diagnosed late

Because every injury is different, a hand specialist can recommend the most appropriate treatment plan for your specific condition.

When Should You See a Hand Specialist?

If you notice a drooping fingertip after an injury, you should schedule an evaluation as soon as possible. The sooner treatment begins, the greater the likelihood of restoring normal finger function.
