EDS – Boutonniere Splints
Some patients find the Boutonniere splint to be more comfortable with hyperextension greater than 20° or when subluxation of the joint is occurring. This splint is worn with the oval spacer under the joint to block hyperextension while allowing functional flexion. It positions the two rings farther from the joint for better leverage at a more comfortable angle. Depending on the finger length, these can also be overlapped.
