For Severe Hyperextension

Use the SIRIS™ Boutonniere Splint for more 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.
