Thumb IP For Severe Hyperextension

SilverRing™ Boutonniere Splint on the Thumb IP joint

Use the SilverRing™ Boutonniere Splint, worn with the spacer under the IP joint, for more severe hyperextension (greater than 30 degrees). This splint allows full flexion while positioning the two rings farther from the joint for better leverage at a more comfortable angle.
