Abstract
A method of inserting and positioning an intervertebral spacer is provided. The spacer includes a longitudinal axis, an on-axis interface coincident with or parallel to the longitudinal axis, and an off-axis interface angled to the longitudinal axis. The spacer's front end may be curved. The method may include inserting the spacer into the disc space utilizing a tool to engage an on-axis interface and then to engage one or more of the off-axis interfaces, which may be used for further modification of the spacer. The tool is moved substantially along a single insertion direction, which may be substantially parallel to a posterior-anterior axis of the disc space. The method may result in the longitudinal axis of the spacer being perpendicular to the insertion direction, or substantially parallel to a medial-lateral axis of the disc space. The spacer may also be positioned in an anterior aspect of the disc space.
