Stand Alone Intervertebral Fusion Device

摘要

An angled fixation device, such as an angled screw. This angled fixation device may be used by the surgeon to secure a spacer to a spinal disc space. The proximal end portion of the angled fixation device is driven perpendicular to the anterior wall of the spacer, and so is parallel to the vertebral endplates and in-line with the inserter. The distal end portion of the angled fixation device is oriented at about a 45 degree angle (plus or minus 30 degrees) to the vertebral endplate it enters.

主权项

1. An intervertebral fusion device comprising:
i) an intervertebral spacer including;
a) a proximal wall that defines a proximal surface;b) a distal wall opposite the proximal wall, andc) first and second side walls connected between the proximal and distal walls; and ii) a retaining plate that defines a through-hole extending therethrough, wherein the retaining plate is slidable along the proximal surface of the intervertebral spacer; and iii) a screw received by the through-hole of the retaining plate.
