Cruciform Extension Orthosis

This spinal hyperextension orthosis is specifically designed to extend the thoracic spine, prevent forward flexion and limit rotation. The patented compound closure system provides excellent low back support, additional comfort and adjustable relief. Effective stabilization allows patients to resume activities of daily living and reduces the tendency for deconditioning secondary to inactivity.
