INTERVERTEBRAL CAGE AND METHOD OF TREATING VERTEBRAE WITH AN INTERVERTEBRAL CAGE

摘要

The present disclosure provides an intervertebral cage including superior and inferior members each including an engagement surface for engaging a corresponding vertebrae. The intervertebral cage also includes a posterior member that extends between a posterior end of the superior and inferior members and spaces them from each other in a superior-inferior direction. The superior and inferior members extend in a posterior-to-anterior direction from the posterior member and define anterior free ends to form a substantially open anterior end between the superior member and the inferior member in a posterior-anterior direction. The engagement surfaces of the superior and inferior members substantially diverge from each other in the superior-inferior direction along the posterior-to-anterior direction. The superior and inferior members each include first apertures extending therethrough in the superior-inferior direction that define a pathway through the intervertebral cage in the superior-inferior direction.

主权项

1. An intervertebral cage, comprising:
a superior member including a first engagement surface for engaging a superior vertebrae; an inferior member including a second engagement surface for engaging an inferior vertebrae; a posterior member extending between a first end of the superior member and a first end of the inferior member, the posterior member spacing the first ends of the superior member and the inferior member in a superior-inferior direction, wherein the superior member and the inferior member extend in a posterior-to-anterior direction from the posterior member and define anterior free second ends to form a open anterior end between the superior member and the inferior member in a posterior-anterior direction, wherein the first engagement surface of the superior member and the second engagement surface of the inferior member substantially diverge from each other in the superior-inferior direction along the posterior-to-anterior direction from the posterior member to the free second ends thereof, and wherein the superior member and the inferior member each include first apertures extending therethrough in the superior-inferior direction that at least partially overlap in the superior-inferior direction and define a first pathway through the intervertebral cage in the superior-inferior direction.
