Disclosed are system and methods that use at least one non-threaded anchor and an implant with at least one aperture to join boney structures, where the interaction of the head of the anchor with the implant aperture causes the anchor to move transversely with respect to an initial trajectory. This movement causes compression or distraction of the boney structures which are coupled to the anchors.

A bone screw implant comprising a bone screw and a sleeve. The bone screw includes a first end, a second end opposite the first end, a cannula extending from the first end to the second end, an externally treaded portion provided between the first end and the second end, and at least one cutting flute. The at least one cutting flute extending from the first end toward the second end, where the cutting flute comprises at least one window extending through the cutting flute and in communication with the cannula. The sleeve comprising a cylindrical body portion extending about the second end of the bone screw, and a plurality of projections extending from the cylindrical body portion configured to engage bone as the bone screw is threadingly advanced.

The preferred embodiment of the present invention is generally described as a lordotic pre-sacral rod implant, or implant construct, for use in association with spinal fusion procedures. In an embodiment, the lordotic pre-sacral rod implant incorporates a washer configured to press against the endplate of the L5 vertebral body and thereby force the vertebral bodies of the lumbosacral junction into a lordotic orientation.

A lumbar interbody fusion device includes a first wing, a second wing, and a bridge. The bridge has an arcuate resting shape and include a first end connected to the first wing, a second end connected to the second wing, and at least one aperture extending through the bridge in a radial direction relative to the arcuate resting shape of the bridge. The bridge is elastically deformable such that a distance between the first wing and the second wing may vary according to elastic deformation of the bridge.

A fixation implant includes a head, a shank and a distal tip, and one or more of the head, shank and distal tip may be cannulated. The shank includes a threaded ingrowth portion extending from the head to the tapered distal tip that includes external threads, and at least one open network body extending along the length of the ingrowth portion. The open network body selected from one or a combination of a helix, an arrangement of trusses, a scaffold of open and interconnected pores, a porous framework of random open and interconnected pores, and combinations of these.

A method of joining adjacent bone includes providing a medical device having a first implant portion, a second implant portion attached to the first implant portion, and a driver assembly having an instrument adapted to form an opening in bone. The driver assembly is integrally connected to and removably attached to the second implant portion at a connection, distal from the first implant portion. The driver assembly further has a wire driver extending therefrom, distal from the first implant portion. The method further includes inserting the wire driver into a wire driver tool; placing the first implant portion against a first bone structure; inserting the first implant portion into the first bone structure; removing the second implant portion from the driver assembly; using the driver assembly to form an opening in a second bone structure, adjacent to the first bone structure; and inserting the second implant portion into the opening.

The preferred embodiment of the present invention is generally described as a lordotic pre-sacral rod implant, or implant construct, for use in association with spinal fusion procedures. In an embodiment, the lordotic pre-sacral rod implant incorporates a washer configured to press against the endplate of the L5 vertebral body and thereby force the vertebral bodies of the lumbosacral junction into a lordotic orientation.

An expandable spinal implant is provided having first and second endplates hinged along one end or otherwise connected by pins, protrusions and channels, or similar mechanisms and an expansion mechanism(s) disposed therebetween configured to expand the first and second endplates from each other. Also provided are expandable spinal implants that may be expanded in a parallel manner to increase the height of the device while maintaining a lordotic angle. Other spinal implants may provide dual expansion whereby both height and lordotic angle are adjusted. Various implants, systems and methods are disclosed.

Various embodiments of a coupler and an intradiscal implant for alignment and fusion of the sacroiliac joint are described herein.

Arthrodesis surgical methods and apparatus. After a guide pin is inserted into the joint to be fused, a core saw creates a cored-out cavity in the joint to be fixated. An autograft bone core is harvested with a core saw and is inserted into the cored-out cavity. The joint is then immobilized for the healing process.
