Intervertebral implant

摘要

A method for fixation of an intervertebral implant includes the steps of: a) applying a spreading force to a first and second adjacent vertebral bodies; b) removing the intervertebral disc between the adjacent first and second vertebral bodies; c) inserting a shaft of the bone anchors into the vertebral bodies, and fixing a head of the bone anchors to an intervertebral implant.

主权项

1. An intervertebral implant assembly comprising:
an intervertebral implant body defining a first bone contacting surface and a second bone contacting surface spaced apart from the first bone contacting surface along a central axis, at least one of the first and second bone contacting surfaces defining at least one recess that extends into the implant body but not through the implant body, and at least one recess opening for each respective recess, the at least one recess opening extending transversely with respect to the central axis and being aligned with the respective first and second bone contacting surfaces, the at least one recess opening being sized to receive a head of a bone anchor therethrough so that a shaft of the bone anchor extends out from the respective at least one of the first and second bone contacting surfaces when the at least one recess receives the head of the bone anchor, wherein the at least one recess opening is configured to receive the head of the bone anchor after the shaft has been inserted into a vertebral body.
