The symptoms of a mallet finger

Mallet finger is characterized by an inability to straighten the tip of a finger (the distal phalange joint). It usually occurs after a tear in an extensor tendon, and while the middle or ring fingers are most often affected, the condition can impact other fingers.

What are the most common causes?

A minor injury to the finger can cause the extensor tendon to detach from the bone, so the last joint in the finger is unable to straighten. This is a frequent injury in manual workers, swimmers or players of ball sports. It can even be caused by very common daily activities, such as tucking a sheet under a mattress.

What are the symptoms?

Typically, the last joint of the finger is crooked and is often accompanied by slight swelling and tenderness. There is generally no bruising or pain, although there can be moderate pain in some cases.

How is it diagnosed?

Deformity in the finger is typical, and observation is generally sufficient for diagnosis. X-rays are important in ruling out a fracture.
