Swan neck deformity is a hand deformity in which your fingers are bent abnormally. Your finger's middle joint bends back more than usual. The tip of your finger is bent down. Swan neck deformity only affects your fingers. Your thumb isn't affected, as it has one less joint than your fingers.Nov 9, 2021
The usual cause of a swan neck deformity is weakness or tearing of a ligament on the palm side of the middle joint of the finger. Sometimes it is caused by tearing of the tendon that flexes the middle joint. In other cases, injury of the tendon that straightens the end joint is the cause.Feb 15, 2018

The treatment for SND can vary, depending on the condition's severity. Noninvasive treatments include physical therapy (PT), occupational therapy (OT), and splints. More invasive procedures include surgery. These can range from minor soft tissue repair to more drastic measures like replacing or fusing the finger joint.
Swan neck deformity is the result of ligament and joint damage. Hyperextension of the middle finger joint forms a shallow “V” shape, while a flexion in the joint farthest from the palm points the fingertip downward. The resulting shape may resemble that of a swan's neck.Jul 20, 2021
Swan neck and boutonniere deformities of the proximal interphalangeal (PIP) joint are challenging to treat. In a swan neck deformity, the PIP joint is hyperextended with flexion at the distal interphalangeal (DIP) joint. In a boutonniere deformity, there is flexion the PIP joint with hyperextension of the DIP joint.

Mallet finger leads to an imbalance in the distribution of the extensor force between the proximal interphalangeal (PIP) and DIP joints. If left untreated, mallet finger leads to a swan neck deformity from PIP joint hyper extension and DIP joint flexion.Feb 25, 2014
It is suggested that the usual "intrinsic-plus" hand and the fixed swan neck deformity of rheumatoid arthritis is caused by adhesions between the extensor tendons on the dorsum of the proximal interphalangeal joint, rather than by intrinsic muscle contracture and/or metacarpo-phalangeal dislocation.
