Abstract:
1. A method of inserting and positioning a prosthetic intervertebral spacer in the intervertebral disc space between two adjacent vertebrae, the method comprising the steps of: providing a spacer including a longitudinal axis, an on-axis interface, and an off-axis interface, the on-axis interface being coincident with or parallel to the longitudinal axis, and the off-axis interface being angled with respect to the longitudinal axis; engaging a tool to the on-axis interface; inserting the spacer at least partially into the intervertebral disc space by moving the tool substantially along an insertion direction; engaging the tool to the off-axis interface; inserting the spacer further into the intervertebral disc space by moving the tool substantially along the insertion direction, such that the longitudinal axis of the spacer is angled with respect to the insertion direction; and modifying the shape of the spacer by expanding the spacer.
