Swan Neck Deformity
SWAN NECK DEFORMITY
Swan Neck Deformity is a finger condition characterized by the middle knuckle bending backwards beyond the normal range (hyperextending) and the fingertip bending down towards the palm (flexing). As the middle knuckle bends backwards, it may be difficult to get your finger to bend when you try to make a fist. This problem is commonly seen in people with Rheumatoid
Arthritis, where inflammation (swelling) weakens the tissues that
protect the joints and keeps them stable.
Swan Neck Deformity may also result from an untreated Mallet
Finger where the loss of the ability to straighten the end of the finger
eventually affects the middle knuckle as well.
Those with Ehlers Danlos Syndrome (EDS), a genetic condition that affects the connective tissue, experience Swan Neck Deformity in their fingers due to the hyper-flexibility common in the disease.

What Can I Do About It?
Wearing a finger splint that stops the middle knuckle from bending backwards allows you to more easily bend and straighten your finger. A properly fit finger splint that prevents the tissues around the joint from overstretching may also prevent the deformity from getting worse.
As in most conditions, early treatment of a Swan Neck or a Mallet Finger is important to avoid complications that may result in the need for surgery.
