What Is a Mallet Finger Injury and How Is It Treated?

What Is a Mallet Finger Injury and How Is It Treated?

Mallet finger injuries are a common but often underestimated problem. This type of injury affects your fingertip's ability to straighten and can be caused by various factors, from sports mishaps to everyday accidents.

We’re here to restore full strength and movement with expert treatment and rehabilitation. 

In the meantime, we’ll dive into the world of mallet finger injuries, exploring what they are, their causes, and how they can be treated effectively.

What is a mallet finger injury? 

Imagine trying to extend your finger, but it stubbornly remains bent at the tip. This condition, often referred to as "baseball finger" or "dropped finger," is a mallet finger injury. 

Here's what you need to know about it:

Anatomy of the injury 

A mallet finger injury occurs when your extensor tendon, which is responsible for straightening your fingertip, is damaged or torn. It often results from a forceful blow to your fingertip, jamming it in a bent position.

Common causes

Mallet finger injuries can happen in various ways, such as playing sports, slamming a door on your finger, or even while doing household chores. Any activity that puts excessive pressure on your fingertip can potentially lead to this injury.

Identifying mallet finger symptoms 

Now that you understand what a mallet finger injury is, it’s essential to recognize the symptoms. Early diagnosis can significantly impact the effectiveness of treatment. 

Here are the key signs to look for: 

Bent finger

The most evident symptom is a fingertip that droops or remains bent, unable to straighten on its own.

Pain and swelling 

Your injured finger may be painful and swollen, often accompanied by tenderness around the affected area.

Difficulty straightening 

The inability to straighten your fingertip is a hallmark of mallet finger.

Possible nail deformity

In some cases, your nail may become misshapen or show signs of damage.

Treating mallet finger injuries

Once a mallet finger injury is identified, the next crucial step is treatment. Depending on the severity of your injury, there are various approaches to consider. Let's explore treatment options:

Splinting

For less severe mallet finger injuries, splinting is often the first line of treatment. A splint, usually worn for several weeks, helps keep your fingertip extended while your tendon heals. Compliance is essential, as removing the splint too soon can hinder your recovery process.

Surgery 

In more severe cases, when your tendon is significantly damaged or there’s a fracture involved, surgical intervention may be necessary. Surgery aims to repair your damaged tendon or bone and restore your finger's functionality.

Rehabilitation

Regardless of the chosen treatment method, rehabilitation exercises play a crucial role in regaining strength and mobility in your affected finger. These exercises are typically guided by our team and can be performed at home.

Preventing complications

Left untreated, a mallet finger injury can lead to complications, such as joint deformities or chronic pain. Therefore, seeking prompt medical attention is crucial to prevent long-term issues.

Understanding mallet finger injuries and the treatment options is essential for anyone who may encounter this common injury. By recognizing the symptoms early and seeking the appropriate treatment, you can ensure a smoother road to recovery and reduce your risk of complications.
