Inter-vertebral implant with angled plate
First Claim
1. An inter-vertebral implant for insertion between a first spinal vertebra and a second spinal vertebra, comprising:
- a hollow frame 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;
a plate arranged along a plane (P), and attached to the front surface of the implant at a fixed angle, defining the front surface of the implant, the plate including a plurality of clearance holes for receiving a corresponding plurality of medical fasteners;
and,two solid side surfaces extending between the front surface and the rear surface, each side surface including a solid side panel which has a portion that X-ray translucent encompassed by a portion that is opaque,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 an elongated top load bearing surface and an elongated bottom load bearing surface, and wherein the plane (P) is at a non-right angle with respect to the axis of the elongation (A).

Abstract
An inter-vertebral implant 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. A 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-right angle relative to the plane (P).
