Violet, your outpatient, has severe rheumatoid arthritis with swan neck deformities in all of her fingers. She is open to using splints to correct these deformities, but would like something that will last a long time. What type of splint does your OT department recommend for Violet?
  1. Finger flexion spring splints
  2. Thermoplastic extension block splints
  3. Reverse knuckle bender splints
  4. Murphy rings
Explanation
Answer: D. Your OT department recommends Murphy rings for Violet. Murphy rings act like extension block splints because they prevent hyperextension of the proximal interphalangeal (PIP) joints and help correct swan neck deformity. Murphy rings are made of metal and are much more durable than thermoplastic splints. They also provide lateral stability and are more attractive than thermoplastic splints.
