20130096687 | Artificial Hemi-Lumbar Interbody Spinal Fusion Cage Having an Asymmetrical Leading End - 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. | 04-18-2013 |
20130096688 | Interbody Spinal Fusion Implant Having A Trailing End With At Least One Stabilization Element - 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. | 04-18-2013 |
20130204300 | SINGLE-LOCK ANTERIOR CERVICAL PLATE - Anatomically contoured anterior cervical plates with bone ingrowth surfaces, providing for intersegmental compressive preloading, and a rigid and locked interface to all of the bone screws, with those engaging the vertebrae deployed in highly convergent pairs. The bone screws have a tapered self-tapping leading end, an increasing root diameter with a generally constant outer diameter with a thread that is narrow and sharp throughout and an enlarged head portion capable of an interference fit to the receiving holes of the plate. Instrumentation consists of plate holders, a compression apparatus and a pilot hole forming device that interlocks with the plate. Methods for spinal compression and bone hole preparation are provided. | 08-08-2013 |
20130218279 | PUSH-IN INTERBODY SPINAL FUSION IMPLANTS FOR USE WITH SELF-LOCKING SCREWS - An apparatus including an interbody spinal fusion implant having a leading end, a trailing end, and a length therebetween, and opposed upper and lower portions adapted to contact each of the adjacent vertebral bodies. Each of the upper and lower portions having at least one opening adapted to communicate with one each of the adjacent vertebral bodies and to communicate with one another to permit for the growth of bone from vertebral body to adjacent vertebral body through the implant. Each of the upper and lower portions has at least one screw hole passing therethrough proximate the trailing end. The apparatus further includes bone screws adapted for placement through the screw holes of the upper and lower portions and into each of the adjacent vertebral bodies adjacent the disc space to be fused and into which the implant is adapted to be positioned. At least one lock may be used to prevent the bone screws from backing out of the vertebral bodies and implant. | 08-22-2013 |
20130245771 | METHOD FOR LOADING A SPINAL IMPLANT - A method for loading a spinal implant with fusion promoting substances into an implantation space adjacent vertebral bodies of the spine. | 09-19-2013 |
20130296942 | ORTHOPEDIC IMPLANT WITH LOCKING ELEMENT - An orthopedic implant with a locking element for locking a bone screw in a bone screw receiving hole of the implant. | 11-07-2013 |
20140067074 | SPINAL IMPLANT HAVING DEPLOYABLE BONE ENGAGING PROJECTIONS - 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. | 03-06-2014 |
20140265461 | ADJUSTABLE CHILD BOOSTER SEAT - 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. | 09-18-2014 |
20140265487 | ADJUSTABLE CHILD BOOSTER SEAT - An adjustable 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. | 09-18-2014 |
20140316476 | Method for Using a Guard for Creating a Socket Posteriorly in the Lumbar Spine - 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. | 10-23-2014 |
