Abstract: An instrument for use in a procedure for inserting a spinal implant between human vertebrae may include a shaft and an end member. The end member may rotate with respect to the shaft. An angle of the end member with respect to the shaft may be varied when the end member is in a disc space between the human vertebrae. The instrument may include a slide for securing the end member at selected angles relative to the shaft. The end member may be separable from the shaft when the end member is in a selected orientation with the shaft. An instrument kit may include a shaft assembly and modular end members for various steps in a surgical procedure, such as disc space preparation, disc space evaluation, and spinal implant insertion.

Abstract: A spinal implant may be used to stabilize a portion of a spine. The implant may promote bone growth between adjacent vertebrae that fuses the vertebrae together. An implant may include an opening through a height of a body of the implant. The body of the implant may include curved sides. A top and/or a bottom of the implant may include protrusions that contact and/or engage vertebral surfaces to prevent backout of the implant from the disc space. A variety of instruments may be used to prepare a disc space and insert an implant. The instruments may include, but are not limited to, a distractor, a rasp, and one or more guides. The implant and instruments may be supplied in an instrument kit.
