Abstract
A spinal implant for implantation in an intervertebral space is provided, such that the implant may provide a back-out prevention feature and may also provide a visual indication of whether the back-out prevention feature is engaged. The visual indication may be a contrast between a circular visible shape of the screw head and a non-circular visible shape of the screw head. The back-out prevention feature may provide engagement of a tapered thread in the screw head with an internal thread of the implant. A hard stop may also be provided. Such back-out prevention feature may also provide a torque-based indication of engagement or non-engagement of the back-out prevention feature. The implant may possess a polymeric posterior body joined to a metallic anterior body.
