Mallet Finger: Causes, Symptoms, and Treatment
Mallet finger is a common hand injury that affects the tip of the finger. It happens when the tendon that straightens the finger is damaged, causing the fingertip to droop and making it hard or impossible to fully straighten.
Mallet finger often occurs during sports but can also happen during everyday activities.
What Is Mallet Finger?
Mallet finger occurs when the extensor tendon at the end of the finger is torn or pulled away from the bone. In some cases, a small piece of bone may also break where the tendon attaches.
This injury usually affects the last joint of the finger and most often involves the index, middle, or ring finger.
What Causes Mallet Finger?
Mallet finger is usually caused by a sudden force to the fingertip.
Common causes include:
-
A ball striking the tip of the finger
-
Sports such as baseball, basketball, or volleyball
-
Jamming the finger
-
Falls or accidents
-
Catching the finger on clothing or objects
Symptoms of Mallet Finger
Symptoms are often noticeable right away.
Common symptoms include:
-
Drooping of the fingertip
-
Inability to straighten the finger
-
Pain or tenderness at the fingertip
-
Swelling or bruising
-
Redness around the joint
Without treatment, the finger may heal in a bent position.
How Is Mallet Finger Diagnosed?
An orthopaedic specialist can usually diagnose mallet finger with a physical exam. X-rays may be used to check for a fracture or confirm the severity of the injury.
Treatment Options for Mallet Finger
Most cases of mallet finger can be treated without surgery when addressed early.
Non-Surgical Treatment
-
Wearing a finger splint to keep the finger straight
-
Continuous splinting for several weeks

Avoiding activities that bend the finger
It is very important to keep the finger straight during healing, even briefly bending it can delay recovery.

Surgery may be recommended if:
-
There is a large bone fracture
-
The joint is not aligned
-
Non-surgical treatment does not work
An orthopaedic specialist will determine the best treatment plan.
