Hand and Finger Rheumatoid Arthritis
What is a swan-neck deformity?
Rheumatoid arthritis is a common cause of a swan-neck deformity.
With a swan-neck deformity, the base of the finger and the outermost joint bend, while the middle joint straightens. Over time, this imbalance of the finger joints can result in the crooked swan-neck position. (True swan-neck deformity does not occur in the thumb.)
A swan-neck deformity can make it almost impossible to bend the affected finger normally; it can make it difficult to button shirts, grip a glass, or pinch with the fingers.
By examining the hand and fingers, a rheumatologist can diagnose a swan-neck deformity and determine appropriate treatment, which may include:
- Finger splints or ring splints
- Surgery to realign the joints or fuse the joints for better function
What is a boutonniere deformity?
Boutonniere deformity, also called buttonhole deformity, can occur as a result of rheumatoid arthritis.
With a boutonniere deformity, the middle finger joint will bend toward the palm while the outer finger joint may bend opposite the palm. This deformity may be the result of chronic inflammation of the finger's middle joint.
Treatment for boutonniere deformity may include splinting to keep the middle joint extended. Surgery may be needed.
