A swan neck deformity is an abnormal position of the finger where the middle joint bends backwards (hyperextends) and the fingertip joint bends forwards (flexes). This creates a characteristic curved appearance resembling a swan’s neck and can affect finger movement and hand function.
Visually Swan Neck Deformity is the opposite of Boutonniere deformity.
Is this an emergency?
No, Swan neck deformity is generally not an emergency and often develops gradually. Medical assessment is recommended to determine the underlying cause and prevent further progression. If a swan neck deformity suddenly occurs following a trauma or injury seek urgent medical assessment.
