The ISOLA/VSP Spine System is a comprehensive and versatile hook, rod and screw system that can be used for both deformity and degenerative cases.

Conceived with a complete understanding of the spine in 3-dimensions, the ISOLA/VSP Spine System employs segmental fixation and translation techniques to correctly align and stabilize the spine. The ISOLA Spine System has enjoyed more than 10 years of clinical success and remains one of the most popular rod-based systems in the deformity/degenerative market.

All of these multiple hook and contourable rod systems deal with a problem of scoliosis which was not addressed by earlier systems. When the spine curves sideways, the vertebrae rotate towards the concavity of the curve. Since the ribs are attached to the spine, they are dragged along and splayed out on the convex side of the curve and compressed on the concave side. (This is what creates the rib hump seen in a thoracic curve.)
