摘要： The embodiments provide a spinal implant that is configured for midline insertion into a patient's intervertebral disc space. The spinal implant may have a body and the body comprises one or more apertures. The apertures receive fixation elements, such as a screw and the like. The fixation element may comprise one or more anti-backout features, such as a split ring. In addition, at least some of the apertures are designed to permit a predetermined amount of nutation by a fixation element. The apertures that allow nutation enable the fixation element to toggle from one position to another, for example, during subsidence of the implant in situ. Some of the apertures may be configured to rigidly lock with the fixation elements. Moreover, the spinal implant may include features, such as one or more bores, that can accommodate imaging marks to help guide a surgeon.
