Mallet Finger

What Is Mallet Finger?

Mallet finger occurs when the thin tendon responsible for straightening the distal joint of the finger or thumb is damaged. If this injury is not addressed, it can result in a permanent droop of the fingertip, along with lasting stiffness and physical deformity.

What Causes Mallet Finger?

This condition is caused by damage to the extensor tendon, which is necessary for extending the final joint of the finger. Generally, these injuries fall into two categories:

• Tendon Rupture: This happens when a sudden force—such as a cut or jamming your finger—causes the tendon to tear. In some cases, this can also develop gradually due to the effects of arthritis.
• Bony Mallet Finger: In this version of the injury, a small fragment of bone breaks away at the point where the tendon attaches, which prevents the tendon from successfully moving the fingertip.

Common scenarios that lead to mallet finger include sports-related accidents, deep lacerations on the back of the finger, or forceful bending of the tip during daily tasks like scrubbing or lifting heavy objects.

What are Signs and Symptoms of Mallet Finger?

You may be experiencing a mallet finger injury if you notice any of the following:

• Swelling, bruising, or pain located at the tip of the finger
• A fingertip that droops and cannot be straightened independently
• The appearance of a small bump just beneath the fingernail
• Detachment of the nail or blood collecting under the nail (typically seen in more severe cases)

While some people may have a slight natural droop due to flexible tissue, the vast majority of mallet finger cases are the result of acute trauma.

How is Mallet Finger Treated?

The majority of mallet finger injuries can be successfully managed without surgical intervention.

• Splinting: To ensure proper healing, the fingertip is held in a straight position using a splint for approximately 6 to 8 weeks. Because even a small amount of bending can reset the injury and disrupt the healing process, strict adherence to the splinting schedule is critical.
• RICE Protocol: To manage inflammation and reduce swelling, patients are encouraged to use Rest, Ice, Compression, and Elevation.
• Hand Therapy: While the end joint is immobilized, specific exercises for the middle joint are used to preserve overall mobility.

Once the bone or tendon has healed, your provider may recommend wearing the splint only during sports or while sleeping for a few more weeks to avoid re-injury. It is important to note that some minor changes in contour or a slight droop may persist even after successful treatment.

Surgery for Mallet Finger

In certain instances, surgery becomes necessary. This typically occurs if the joint is misaligned, there is a significant bone fragment, or if non-surgical splinting has failed or is not a viable option. Surgical interventions may include:

• Using screws or wires to realign the joint
• Reconstructing or repairing the damaged tendon
• Fusing the joint to ensure it remains straight

How Long Does Mallet Finger Take to Heal?

With consistent and proper care, most patients regain a high level of function and a natural appearance in their fingertip. The recovery process can span several weeks to several months, often requiring guided exercises to restore full motion. Seeking medical attention early is the best way to improve outcomes and minimize the risk of permanent deformity.
