Claim:
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 contact site for interfacing with a tool, and an off-axis contact site for interfacing with a tool, the on-axis contact site being coincident with or parallel to the longitudinal axis, and the off-axis contact site being angled with respect to the longitudinal axis; applying a first force to the on-axis contact site to move the spacer in the intervertebral disc space, including threading a portion of the tool into a threaded hole aligned with the longitudinal axis; applying a second force to the off-axis contact site to further move the spacer in the intervertebral disc space; and expanding a height of the spacer by separating a top surface of the spacer from a bottom surface of the spacer.
