Swan Neck Deformity Physiotherapy in Indirapuram

Swan neck deformity is the mirror image of boutonniere: the middle finger joint bends backward too far while the fingertip bends down. It often develops with rheumatoid arthritis, after mallet finger, or with very loose joints.

Causes

The balance of tendons and ligaments around the finger joints is delicate. In rheumatoid arthritis, inflammation loosens the structures on the palm side of the middle joint, so it hyperextends. An untreated mallet finger can shift tendon forces in a way that leads to swan neck over time. People with very flexible joints or certain neurological conditions may also develop it.

Why it's a functional problem

When the middle joint overextends, the finger can get stuck straight and it becomes hard to start bending. Some people find their fingers snap or catch as they try to make a fist. Grip and pinch become less effective, and tasks like holding a pen or turning keys get awkward.

Treatment

Small ring splints, often shaped like a figure eight, stop the middle joint from hyperextending while still allowing it to bend. They're discreet and many people wear them all day. Wax therapy can ease stiffness in arthritic hands. Exercises maintain range of motion and strength.

For rheumatoid arthritis, joint protection education matters: using larger handles, spreading load across both hands, and avoiding tight pinch grips. Medication to control the disease is essential.

Surgery can help selected cases where splints and therapy aren't enough.
