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 lateral spine implant has a plate, configured bone screws, and configured setscrews providing locking of bone screw movement. The plate has at least two identically configured bone screw bores, each one with a spherical seat at a bottom opening, and threads around the inner circumference of a top opening. Each setscrew has a cylindrical body with external threads that mate with inner threads of the bone screw bore in order to affix the setscrew to the plate. A threaded spherical pocket is provided in a bottom of the setscrew body which conjoins with the spherical bone screw head to secure the setscrew with the bone screw head, fixing bone screw orientation/angulation. The bone screw head has a formation or formations about at least a portion of its exterior circumference that cooperate with the threads of the spherical pocket of the plate in order to fix bone screw orientation/angulation.

Abstract: A spine implant (e.g., for a TLIF surgical procedure) is configured to be steered into place during implantation in conjunction with a complementary insertion instrument. The cage of the implant is constrained to a limited range of rotation about a post carried by the cage. The insertion instrument is configured to hold the post while controllably rotating the cage relative to the post in order to angularly position the implant during implantation. Range of rotational motion is controlled by the configuration of a groove in the post. A retaining pin of the implant extends from the cage into the groove of the post to rotationally connect the cage to the post.
