CERVICAL SPACER
First Claim
1. An anterior cervical column support device for insertion between a first spinal vertebra and a second spinal vertebra, comprising:
- a hollow frame having a top load bearing surface and a bottom load bearing surface, wherein the top load bearing surface and the bottom load bearing surface each include an opening allowing access to an interior of the frame;
a rear surface having at least a portion that is opaque to X-rays attached between the top load bearing surface and the bottom load bearing surface and a front surface having at least a portion that is opaque to X-rays extending between the top load bearing surface and the bottom load bearing surface;
an anterior plate arranged along a plane (P), and attached to the front surface of the support device, the front plate including a plurality of clearance holes for receiving a corresponding plurality of medical fasteners for holding the rear plate in position;
wherein the top load bearing surface comprises a first frictional surface for applying frictional forces between the top load bearing surface and an adjacent bone surface; and
the bottom load bearing surface comprises a second frictional surface for applying frictional forces between the bottom load bearing surface and an adjacent bone surface and wherein the top load bearing surface and the bottom load bearing surface between them form an axis of elongation (A) that is an intermediate axis between the elongated top load bearing surface and the elongated bottom load bearing surface, and wherein the plane (P) is at a non-zero angle with respect to the axis of the elongation (A)

Abstract
An anterior cervical column support having a hollow frame having a top load bearing surface and a bottom load bearing surface may be inserted between a first spinal vertebra and a second spinal vertebra. The top load bearing surface and the bottom load bearing surface may each include an opening allowing access to the interior of the frame. A front surface may extend between the top load bearing surface and the bottom load bearing surface, and a rear surface may extend between the top load bearing surface and the bottom load bearing surface. An anterior front plate is attached to the front surface of the support device. The interior front plate may be arranged along a plane (P), and an axis (A) between the top load bearing surface and the bottom load bearing surface may be at a non-zero angle relative to the plane (P)
