Systems and techniques for restoring and maintaining intervertebral anatomy

摘要

Techniques and systems for distracting a spinal disc space and supporting adjacent vertebrae are provided. Trial instruments are insertable into the disc space to determine a desired disc space height and to select a corresponding implant. Implants can be also be self-distracting and the implant providing the desired disc space height can be implanted in the spinal disc space.

主权项

1. A kit, comprising:
at least three implants, each of said at least three implants adapted for insertion in a collapsed disc space between an upper vertebra and a lower vertebra to provide a differing restored disc space height, a selected one of said at least three implants implantable in the collapsed disc space to post-operatively maintain a desired disc space height corresponding to the restored disc space height provided by the selected implant, each of the implants comprising a first height and a second height, said first height of each of said at least three implants being the same and said second height being different for each of said at least three implants; wherein each of said implants including a leading end nose portion comprising the first height, each of said at least three implants comprising the second height between an upper surface and a lower surface thereof, the second height corresponding to the restored disc space height.
