Abstract

A surgical spine implant comprises a solid wedge shape device body is such that said polygonal shape with decreased height posterior and several surfaces that contours to the anatomy of the spine intervertebral space without complex machining across radiuses. The diminished height posteriorly provides for the angulations necessary to accommodate and ensure maintenance of the normal spinal alignment resulting in posterior extension angulations. The device provides ease of application of bone grafts. Such as for impaction of cancellous bone grafts after placement of the device and narrow posterior aspect easily directs grafts. This minimizes the problem of bone grafts hanging up behind the device either to the right or the left of the medial or lateral, which prevents the displacement of the device or prominence of the bone grafts near the spinal canal. The recess hole in the device accommodates a holding insertion tool and ease of bone graft packing 'fill' to ensure a tight fit and immobile the attachment of the disc to the lower vertebrae.
