Jammed Finger

A jammed finger happens when the tip of your finger is pushed straight back toward your hand, often by a ball. The joint swells and stiffens. Most heal well, but some hide a fracture or a torn tendon.

What Is It

Jamming a finger sprains the ligaments around one of the finger joints, usually the middle knuckle. Basketball, volleyball, and catching a ball are the classic causes. It is a type of sprain.

Symptoms

Swelling around a finger joint
Pain when you bend or straighten the finger
Stiffness
Bruising
Trouble making a full fist

Not sure it’s just jammed? A fingertip that droops and will not straighten on its own may be a torn tendon, called mallet finger. A crooked finger may be a broken bone. Both need care within a few days.

Treatment

At your visit: A provider checks the finger’s alignment and tendons, and an X-ray may be taken. A simple jam is treated with buddy taping or a small splint. Mallet finger needs a special splint worn day and night for about 6 weeks.

At home:

Ice for 15 minutes at a time for the first 2 days
Keep the hand raised to limit swelling
Buddy tape it to the next finger for support
Start gentle bending once the pain allows, to prevent stiffness

Most jammed fingers improve within 1 to 3 weeks, though some swelling can last for months.
