Finger Hand Swan Neck Deformity

What is a Swan Neck Deformity?

Swan Neck Deformity
A Swan Neck Deformity is a deformity of the finger in which the middle joint is bent back more than normal, and the tip of the finger is bent down. Sometimes, this deformity can be caused by an injury. Other times, it can happen over time due to a condition such as rheumatoid arthritis.

The odd bending of the finger is usually due to a tear of a ligament in the middle joint of the finger.  Sometimes, the tendon is torn. It causes the tendon to become weak. Eventually, the ability of the tendons to straighten the joint becomes lessened, causing the bending. Here are some signs that you have a Swan Neck Deformity:

  • Difficulty bending the middle joint of your finger
  • Snapping sensation
  • Stiff finger(s)

There are many different treatments available for this deformity. Some of these options include:

  • A ring for the middle joint that will correct the awkward position and stop the snapping
  • Surgery, which could involve re-positioning some of the tendons or replacing the joint

Your treatment will vary depending on your circumstance, such as whether or not your finger is stiff. Visit a hand surgeon to discuss all of your options, both surgical and non-surgical. Find a hand surgeon near you at
