Use the SIRIS™ Boutonniere Splint for severe hyperextension (greater than 20 degrees) or when subluxation of the joint is occurring. This splint is worn with the oval spacer under the joint to block hyperextension while allowing full flexion. It positions the two rings farther from the joint for better leverage at a more comfortable angle.
Are you a therapist measuring for this splint?
Note: When considering splints, it is important to consult with, and be evaluated by, a therapist or other healthcare professional who specializes in treating finger problems and who can give advice on the best splint solutions.
