Mallet Finger

Mallet finger is an injury that occurs when the tendon (extensor tendon) connecting the tip of the finger and the middle section of the finger tears. Also called baseball finger, it is usually caused by a forceful blow to the tip of the finger. The torn tendon prevents the finger from extending fully, giving it a jammed or bent appearance. In some cases, the tendon tears away from the bone so forcefully that a piece of bone breaks off, resulting in a fracture called an avulsion fracture.

Mallet finger causes

Mallet finger is almost always the result of sudden trauma to the finger. Common causes include:

  • Sports injuries, especially from baseball and basketball
  • Jamming the finger forcefully
  • Crush injuries from lifting heavy objects or working with machinery
  • Cuts that sever the tip of the finger

Mallet finger symptoms

In addition to the most obvious symptom of a bent fingertip, mallet finger can also cause the following symptoms:

  • Inability to fully extend the finger
  • Pain and swelling at the fingertip joint

Mallet finger treatment

Mallet finger rarely requires surgery. The most common treatment process for mallet finger includes:

  • Doing stretches and physical therapy to regain tendon strength and elasticity
  • Gradually returning to normal activities
  • Wearing a finger splint for 6-12 weeks as the tendon heals

Surgery is reserved for severe instances of mallet finger where a complex avulsion fracture has occurred, or if the injury is secondary to a laceration. The surgeon will usually repair the tendon and realign the broken finger bone with pins or small screws.

Mallet finger risk factors

This risk of sustaining a finger tendon injury like mallet finger or baseball finger is highest in:

Mallet finger prevention

Since mallet finger is usually caused by injuries, avoiding certain activities like baseball and basketball can help prevent injury. You can also:

  • Follow safety guidelines when lifting heavy objects or using machinery.
  • Stretch the finger tendons before and after periods of exertion.
  • Wear protective hand equipment when using knives or sharp tools.
