Problems Addressed-Lateral Instability

Use the SIRIS™ Lateral Support Splint to correct deviation where there is full range of motion

Use the SIRIS™ Boutonniere Splint to correct deviation of the DIP joint

For Lateral Instability With Full Range of Motion. Use the SIRIS™ Lateral Support Splint to correct lateral deviation and block hyper-extension of a joint, while allowing full flexion. The lateral support, which is the fulcrum point of the splint, is always placed on the side opposite the direction the finger is deviating. For example, if there is ulnar deviation of the finger, you should order a splint with support on the radial side. If the finger is bilaterally unstable, request a splint with support on both sides. This splint can be worn on any of the IP joints of the hand.

For Lateral Instability With Limited Range of Motion. Use the SIRIS™ Realignment and SIRIS™ Boutonniere Splints, worn with the spacer on the side of the joint, to provide the greatest leverage for correcting joint deviation. Order these splints when flexion of the joint is limited to less than 45 degrees, but not for a finger which has full active flexion since the splint will rotate. The SIRIS™ Realignment Splint is designed exclusively for the PIP joint because of its overall length. The SIRIS™ Boutonniere Splint, being shorter, can be used on the DIP joint, the PIP joint of a short finger or the IP joint of the thumb. (See page 13 for more information on the difference between SIRIS™ Realignment and SIRIS™ Boutonniere Splints).

For Lateral Instability With Limited Extension. Use the SIRIS™ Boutonniere Lateral Support Splint to provide extension mobilization and correction of lateral deviation. The lateral support, which is the fulcrum point of the splint, is always placed on the side opposite the direction the finger is deviating. If the finger is bilaterally unstable, request a splint with support on both sides.

Distal Extension. When additional leverage is needed to corect deviation, use an extension added to the distal ring of the SIRIS™ Lateral Support Splint. After initial fit verification, the distal extension is added on the same side that the finger is deviating. Note that the distal extension is not meant to extend out to corect deviation of the DIP joint.
