Internal pedicle insulator

摘要

A pedicle insulator implant is designed to protect the nerves and surrounding tissue from injury by pedicle screws or other surgical devices and instruments. In its basic structure, the implant has a thicker section and a thinner section, the thicker section providing protection for nerves and other sensitive tissues while the thinner section can be deformable and provides grip. In one variation of the basic structure, the thinner section possess a rough surface when it is desirable in situations to provide further grip of the assembly and prevent rotation during the insertion of, for example, a pedicle screw.
