Abstract: This invention relates to a transdiscal screw capable of following a non-linear trajectory. The screw assembly includes a first screw and second screw coupled at a poly-axial joint. The first screw and the second screw capable of rotating independently of each other. The screw can also include a third screw coupled to the second screw at a poly-axial joint such that the first screw, second screw and third screw can rotate independently of each other.

Abstract: A method and system for performing bone fusion and/or securing one or more bones, such as adjacent vertebra, are disclosed.

Abstract: A method and system for performing bone fusion and/or securing one or more bones, such as adjacent vertebra, are disclosed. The screws include a threaded tip connected to a main shaft and a threaded outer sleeve that rotates relative to the outer shaft until locked down. Independent rotation of the threaded outer sleeve relative to the threaded distal tip allows compression or distraction to modify the gap between the vertebral bodies. The screws are passed from the inferior to superior vertebra or superior to inferior, for example, through a trans-pedicular route to avoid neurological compromise. At the same time, the path of screw insertion is oriented to reach superior or inferior vertebra. An intervertebral cage of the system is configured for lateral expansion from a nearly straight configuration to form a large footprint in the disc space. The screws and cage may be combined for improved fixation with minimal invasiveness.

Abstract: A method and system for performing bone fusion and/or securing one or more bones, such as adjacent vertebra, are disclosed. The screw includes a threaded distal piece fixedly attached connected to an inner post. Both the inner post and the proximal piece have non-cylindrical receptacles at their proximal ends for engagement with driving tools. Independent rotation of the proximal piece and the distal piece enables for compression or decompression to modify the gap between two bones or bone fragments. During use, the distal piece of the bone screw is placed at least partially within a distal bone, the proximal piece is placed at least partially within a proximal bone, and one of two pieces is rotated while the other is held in a fixed position, causing movement of the proximal and distal bones relative to each other.
