What is the treatment for swan neck deformity?

The treatment for swan neck deformity primarily involves using a stack splint. This type of splint effectively helps in maintaining the correct position of the fingers, preventing hyperextension at the proximal interphalangeal joint while allowing some movement at the distal interphalangeal joint. This is crucial in managing swan neck deformity, which is characterized by a specific wrist and finger positioning often associated with conditions such as rheumatoid arthritis.

The stack splint is effective because it can be easily adjusted for comfort and fit, thereby promoting compliance in use. By stabilizing the fingers in a functional and aligned position, it helps to reduce pain and may prevent further deformity or functional impairment.

While other options, such as surgical intervention, may be necessary in severe cases or when conservative treatments fail, the stack splint is often the first line of treatment for less severe cases. Buddy taping also does not provide the necessary support and stabilization that a stack splint offers for this specific deformity. An ulnar gutter splint, which is typically used for injuries involving the ulnar aspect of the hand, is not appropriate for treating swan neck deformity directly.
