Abstract
Pedicle-based intradiscal fixation devices, systems, instruments, and methods thereof. The implant or a portion thereof may be composed of a shape-memory material, which has a curved shape-memory orientation and a temporarily straight orientation. The implant may be configured to be inserted into a pedicle of an inferior vertebra, through the vertebral body of the inferior vertebra, and into the vertebral body of the superior vertebra to thereby stabilize the inferior and superior vertebrae.
