Abstract: A method for guiding a bone removal device to form a socket in the human spine and for inserting a cortical bone implant into the socket. The method includes placing a guard against the posterior aspect of the spine, the guard having a passage therethrough, inserting the bone removal device into the passage, removing a portion of a facet joint with the bone removal device to create the socket having a maximum height, and inserting the cortical bone implant into the socket. The cortical bone implant has a leading end, a trailing end, a mid-longitudinal axis through the ends, and a height transverse to the mid-longitudinal axis, the height of the cortical bone implant being greater than the maximum height of the socket.

Abstract: An adjustable height child booster seat including a seat and a base configured to be placed on an elevated surface above ground. The seat may be rotated relative to the base to move the seat and the base relative to each other in to adjust the booster seat to a desired height.

Abstract: An interbody spinal fusion implant made of a material other than bone adapted for placement across an intervertebral space formed across the height of a disc space between two adjacent vertebral bodies. The implant has a trailing end with a bone screw receiving hole for receiving at least one bone screw to engage the vertebral bodies.

Abstract: An interbody spinal fusion implant adapted for placement at least in part across an intervertebral space formed across a disc space between two adjacent vertebral bodies and for penetrating engagement into each of those vertebral bodies, the implant having a trailing end adapted to sit upon and not protrude from the anterolateral peripheral rim of bone of the vertebral body.

Abstract: An interbody spinal fusion implant made of a material other than bone adapted for placement across an intervertebral space formed across the height of a disc space between two adjacent vertebral bodies. The implant has a leading end that is curved to form a portion of a circle from side to side, sides that are at least in part straight, and a trailing end with a bone screw receiving hole for receiving at least one bone screw to engage the vertebral bodies.

Abstract: A flanged interbody spinal fusion implant for insertion at least in part between adjacent vertebral bodies has opposed upper and lower surfaces adapted to contact each of the adjacent vertebral bodies from within the disc space, a leading end for insertion between the adjacent vertebral bodies, and a trailing end opposite the leading end. The trailing end has a height greater than the maximum height of the disc space forming a flanged portion adapted to overlie a part of the anterior aspects of the vertebral bodies adjacent and proximate the disc space to be fused. The flanged portion has at least two bone screw receiving holes, at least one each adapted to overlie each of the adjacent vertebral bodies at least in part. The implant has at least one locking element to lock one or more of the bone screws inserted in the bone screw receiving holes. Instrumentation for inserting the implant, forming screw holes in the vertebral body, and for locking the locking elements are disclosed.

Abstract: Instrumentation is disclosed for inserting an interbody spinal fusion implant for implantation at least in part within and across the generally restored height of a disc space between two adjacent vertebral bodies of a human spine. The implant has an external housing and a substantially hollow internal rotatable member having bone engaging projections that are deployable through the housing to penetrably engage the adjacent vertebral bodies.

Abstract: A plating system includes moveable plate segments to vary the overall length of the plate. The plating system is capable of both passive and active dynamization and has the ability to produce the former from the latter.

Abstract: An artificial interbody spinal implant adapted for placement across an intervertebral space formed across the height of a disc space between two adjacent vertebral bodies is disclosed. The implant has an asymmetrical leading end adapted to sit upon the more peripheral areas, such as the apophyseal rim and the apophyseal rim area, of the vertebral end plate region of the vertebral bodies without protruding therefrom. The asymmetrical leading end allows for the sate use of an implant of maximum length for the implantation space into which it is installed. The implant can also include an asymmetric trailing end adapted to sit upon the more peripheral areas of the vertebral end plate region of the vertebral bodies.

Abstract: A spinal fusion implant for surgical implantation at least in part within a disc space between two adjacent vertebral bodies in a segment of a human spine. The implant has a trailing end with bone screw receiving holes that each have a diameter that intersects with one of the upper and lower surfaces of the implant to form a perimeter that extends from an exterior surface of the trailing end towards an interior surface of the trailing end.
