Abstract: A spine implant for an ALIF procedure includes anchoring members being either a bone screw or flexible barb, each having a head on one end of a shaft, and a tip on another end of the shaft. The spine implant includes a porous cage having a front, rear, central cavity, and three angled bores in the front that extend into the central cavity configured to receive one of the plurality of anchoring members such that the tip of the anchoring member extends from one or another side of the cavity with its head retained in the front. The spine implant further includes two retention members configured for insertion into the front such that a portion of the two retention members are positioned over the heads of two, adjacent anchoring members to inhibit bone anchor backout via cam action between the retention member and the heads of the anchoring members.

Abstract: An orthopedic implant has a plate and bone screws. Configured bone screw pockets of the plate provide variable angling and positional locking of a received bone screw relative. Each bone screw includes distal threads, a neck, and a dual threaded head. The plate has a bone screw pocket on a distal end, a bone screw pocket on a proximal end, and a strut extending between the two bone screw pockets. The bone screw pockets are at least generally cup shaped for receipt of a bone screw. The lower periphery of the opening of each bone screw pocket has an arrangement of configured prongs with configured openings to receive threading on the underside of the dual threaded head of the bone screw. The prongs can preferably, but not necessarily, deform slightly and grab onto the threading of the bone screw head to lock the bone screw in the bone screw pocket. Each prong can act independently.

Abstract: An orthopedic implant has a plate and bone screws. Configured bone screw pockets of the plate provide variable angling and positional locking of a received bone screw relative. Each bone screw includes distal threads, a neck, and a dual threaded head. The plate has a bone screw pocket on a distal end, a bone screw pocket on a proximal end, and a strut extending between the two bone screw pockets. The bone screw pockets are at least generally cup shaped for receipt of a bone screw. The lower periphery of the opening of each bone screw pocket has an arrangement of configured prongs with configured openings to receive threading on the underside of the dual threaded head of the bone screw. The prongs can preferably, but not necessarily, deform slightly and grab onto the threading of the bone screw head to lock the bone screw in the bone screw pocket. Each prong can act independently.

Abstract: A lumbar spine implant has a body with bone screw bores that angle from a metal faceplate situated at an end of the body, the bone screw bores sized such that the bone screw bores become threaded during introduction of a bone screw thereby providing a locking mechanism to prevent the bone screw from backing out. The faceplate also provides a pocket for each bone screw that prevents the bone screw head from advancing through the implant body. The lumbar spine implant has four bone screw bores, two of which extend from the faceplate to the upper side of the body, and two of which extend from the faceplate to the lower side of the body. More or less bone screw bores may be provided. Preferably, but not necessarily, the direction of the bone screw bores are staggered from one lateral side to another lateral side of the body.

Abstract: An interbody spine implant has a PEEK body/cage and removable front, the body with bone screw holes of a diameter smaller than a greatest diameter of an associated bone screw such that received bone screws cut into the PEEK thus locking the bone screws to the body. A major diameter of a bone screw increases towards the head of the screw to cause interference between the PEEK body and the screw. This aids in preventing the screw from backing out of the body. Bone screw holes are angled to project the bone screw from either the top or the bottom of the body for receipt in upper and lower vertebral bone. Preferably, but not necessarily, the direction of the bone screw bores are staggered from one lateral side to another lateral side of the body.
