  • Publication number: 20190247199
    Abstract: A spinal implant system is provided for bridging an intervertebral space between vertebral bodies bordering the intervertebral space. The spinal implant system includes at least one adjustable end cap and a spinal implant. The end cap can be used with additional end caps and/or the spinal implant. Multiple end caps can be stacked on top of one another, and one end cap can be attached to a first end of the spinal implant, and another end cap 10 can be attached to a second end of the spinal implant. Thus, one or more of the end caps can be attached to either end of the spinal implant.
