Jammed Finger and Finger Dislocation

What it is

A jammed finger happens when the tip of the finger is forced back toward the hand, stretching or tearing the ligaments that hold the joint together. Greater force can also tear tendons, break bones, or dislocate the joint.

Symptoms

• Pain and swelling at a finger joint
• Difficulty bending, straightening, or gripping
• A visibly deformed joint after a dislocation

Why it matters

The finger joints are complex, and some injuries cause permanent stiffness or instability if they are missed, even when the finger looks and moves normally at first. It is worth having a jammed finger checked.

Diagnosis

An examination of the finger's position, movement, and swelling, plus X-rays. An MRI or CT scan is occasionally needed.

Treatment

Many injuries are treated with a splint or by buddy taping the finger to its neighbor, often with a hand therapist's guidance. Dislocations are put back in place, and severe injuries such as fracture-dislocations may need surgery.

Recovery

Even after a simple sprain, the finger may stay swollen for up to a year. Good results depend on teamwork between you, your surgeon, and your therapist.
