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).

Abstract: Various exemplary embodiments relate to a spinal implant for insertion between two adjacent vertebrae, the spinal implant including one or more of the following: a cage comprising: a frame sized to be inserted between the vertebrae, the frame comprising a fastener hole and a cage alignment structure, the cage alignment structure comprising at least one of: a cage groove and a cage ridge; a bone plate comprising a bone plate alignment structure a through hole, wherein the bone plate alignment structure comprises at least one of a bone plate groove and a bone plate ridge, and wherein the bone plate alignment structure and the cage alignment structure are configured to interact with each other to provide an indication when the bone plate is properly aligned with the cage; and a fastener to attach the bone plate to the cage when inserted through the through hole and into the fastener hole.

Abstract: Various exemplary embodiments relate to a spinal implant for insertion between two vertebrae including one or more of the following: a cage comprising: a frame including a fastener hole, a lattice structure disposed within the frame and exposed on a top and bottom face of the frame to permit bone growth into the lattice structure, and an inner rim disposed between the lattice structure and a through bore extending through the cage; a bone plate comprising a through hole, and a first and a second screw hole, wherein the first and second screw hole are positioned to overlie the vertebrae when the bone plate is attached to the cage and the cage is inserted between the two vertebrae; and a fastener operable to attach the bone plate to the cage when the fastener is inserted through the through hole of the bone plate and into the fastener hole of the frame.

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.

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. Two side surfaces are attached between the front surface and the rear surface, each side surface having a solid side panel that is at least x-ray translucent. An anterior (front) plate is attached to the front surface of the support device, where the front plate includes clearance holes for receiving fasteners for holding the front plate in position.

Abstract: A device, system and method for securing a plate to a bone. An anchor device has a screw (with a head portion) and a locking disc. The head portion includes a slotted wall defining a plurality of petals disposed around a central opening. The screw further includes an internal bore. The locking disc is rotatably disposed within the central opening, such that in a first rotational position the petals may flex inwardly, and in a second rotational position the petals are substantially prevented from flexing inwardly. A tool for manipulating the anchor device has a shaft with its end configured to mate with the internal bore of the screw to permit selective rotation of the screw, and a sleeve member rotatably and slideably mounted on the shaft having an end that mates with the locking disc to permit selective rotation of the disc.

Abstract: An expandable intervertebral implant includes a bone graft implant dimensioned for insertion within an intervertebral space defined between adjacent vertebrae, able to vertically elevate and expand a plurality of ribs into the surrounding bone. The expandable intervertebral implant has a tubular outer body portion having a cylindrical axial bore with a triangular or elliptical cross-section and a plurality of ribs disposed on its outer body dimensioned to fit snugly within the space and an expansion cylinder with a triangular or elliptical cross-section slidably mounted within the axial bore of the tubular outer body. The tubular outer body portion of the expandable intervertebral implant permits the expansion and retraction of the ribs into or out of the surrounding bone as the expansion cylinder rotates.

Abstract: An anterior cervical plating system is disclosed that includes an anterior cervical plate with a locking mechanism feature, bone screws, and a locking element. The bone screws fasten the anterior cervical plate to the spinal vertebrae and locking elements are inserted into a housing to prevent withdrawal of the bone screws from the vertebrae. The anterior cervical plate has at least one pair of adjacent bone screw holes, with the housing mounted perpendicularly between adjacent bone screw holes. When the bone screws are fully inserted into the vertebrae through the anterior cervical plate, the locking element prevents the retraction of the bone screws from the vertebrae. The elastically-deformable locking element holds the bone screws inside the screw holes.
