Abstract

An intervertebral disc placement system includes a multi part intervertebral disc, such as a mobile core disc, and an associated placement instrument. The placement instrument holds the disc securely with the disc endplates angled for ease of placement of the disc into an intervertebral disc space and quickly releases the implant within the disc space. The disc includes upper and lower plates having notches in inner surfaces for engagement of the placement instrument. The placement instrument has a rotatable key configured to fit into the first and second notches to grasp the disc from the interior and eliminate the need for an external grasping mechanism which could interfere with disc placement.
