Abstract: Expandable fusion devices, systems, instruments, and methods thereof. The expandable fusion implant may include an upper endplate assembly and a lower endplate assembly. The upper and lower endplate assemblies may be configured to expand in width. A rotatable actuator may move one or more driving ramps, which mate with an upper ramp and a lower ramp, respectively. The actuator may cause independent movement of one or more of the driving ramps, thereby causing an expansion in height of the upper and lower endplate assemblies.

Abstract: Pedicle-based intradiscal fixation devices, systems, instruments, and methods thereof. The implant or a portion thereof may be composed of a shape-memory material, which has a curved shape-memory orientation and a temporarily straight orientation. The implant may be configured to be inserted into a pedicle of an inferior vertebra, through the vertebral body of the inferior vertebra, and into the vertebral body of the superior vertebra to thereby stabilize the inferior and superior vertebrae.

Abstract: A spacer separates bones of a joint using a driver tool having a threaded shaft. The spacer has a superior endplate with inferior facing ramps, and an inferior endplate with superior facing ramps. Two bearings are positioned between the endplates, each bearing has superior facing ramps which mate with the inferior facing ramps of the superior endplate, and inferior facing ramps which mate with the superior facing ramps of the inferior endplate. One bearing has a threaded aperture, and the other a thrust surface. A threaded shaft is threaded into the threaded aperture to push against the thrust surface to drive the bearings apart. As the bearings move apart, the mated ramps slide against each other to drive the superior and inferior endplates apart.

Abstract: Intradiscal implants, systems, and methods thereof. The intradiscal system may include an expandable implant and one or more intradiscal implants. The intradiscal implants may be supplemental to or integrated with the expandable implant. The intradiscal implant may include one or more flexible anchors with a straight configuration and a curved configuration. The anchor may be bendable, for example, using a shape-memory material.

Abstract: Articulating expandable fusion devices, systems, instruments, and methods thereof. The articulating expandable fusion implant having a plurality of links is capable of being deployed and articulated inside an intervertebral disc space link by link. After the links are articulated into a polygonal shape, the links may be expanded outwardly into an expanded configuration. Instruments may be provided to articulate and expand the implant.

Abstract: Expandable fusion devices, systems, and methods thereof. The expandable implant may include first and second lateral legs and link plates pivotably joined between them. The lateral legs may include upper and lower endplates configured to engage adjacent vertebrae, an actuator assembly including a rotatable actuator having a shaft and a rotatable nut, and driving ramps positioned along the shaft of the actuator. The actuator assembly may cause independent movement of one or more of the driving ramps, thereby causing an expansion in height of the upper and lower endplates of the lateral legs and passive expansion of the connected link plates.

Abstract: Pedicle-based intradiscal fixation devices, systems, instruments, and methods thereof. An implant for stabilizing an inferior vertebra and a superior vertebra may include a first member and a second member moveably connected to the first member. The implant may have a first, initial insertion orientation and a second, final implantation orientation different from the first, initial insertion orientation. The first member may be configured to be inserted through a pedicle of the inferior vertebra and the second member may be configured to engage bone of the superior vertebra in the second, final implantation orientation.
