Swan Neck Deformity
Definition
Swan neck deformity is a condition characterized by an abnormal bending of the finger joints, resulting in hyperextension of the joint at the base of the finger and flexion of the joint closest to the fingertip. This deformity often occurs due to an imbalance in the tendons and ligaments surrounding the finger joints, and can be associated with conditions such as rheumatoid arthritis, nerve damage, or trauma.
