Use the SIRIS™ Swan Neck Splint to block hyperextension of the thumb IP joint

Use the SIRIS™ Boutonniere Splint for severe hyperextension of a subluxed joint

Use the SIRIS™ Boutonniere Splint for lateral deviation of an enlarged thumb IP joint

For Mild to Moderate Hyperextension. Use the SIRIS™ Swan Neck or SIRIS™ Spiral Splint for mild to moderate hyperextension (less than 30 degrees) of the IP joint of the thumb. This will greatly improve power and prehension of the thumb by stabilizing the joint without limiting flexion.

For Severe Hyperextension. Use the SIRIS™ 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.

For General IP Instability. Use the SIRIS™ Spiral Splint to treat lateral instability and hyper-extension of the IP joint of the thumb. This splint allows full flexion and has the greatest adjustability for enlarged joints. The spirals can be loosened or tightened, they can be spread apart or compressed to change the length, and the entire splint can be bent to adjust the angle at which the joint is held. Since this splint blocks hyper-extension and corrects deviation, prehension is more powerful and less painful.

For IP Lateral Deviation. Use the SIRIS™ Lateral Support Splint for lateral deviation of an IP joint that is not enlarged. Use the SIRIS™ Boutonniere Splint, worn with the spacer on the side, for lateral deviation of an enlarged IP joint.

For IP Extension Mobilization. The SIRIS™ Boutonniere Splint is another option for providing extension mobilization of the IP joint of the thumb. When the spacer is positioned on top of the IP joint, flexion is blocked.
