Various embodiments of an intervertebral implant comprise a body extending longitudinally along a primary axis, a baseplate, a plurality of elongated arms having a vertebral supp01i surface, the arms being articulated such that the implant has a folded-back position in which the arms are close to each other, and a deployed position in which the arms are moved away from each other, and expansion means between the folded-back and deployed positions, comprising at least two branches pivotably mounted relative to each other and attached to the elongated arms by guide means such that translation of the expansion means parallel to the primary axis causes pivoting of the branches and moves the arms away from each other.

Expandable fusion devices, systems, and methods thereof. The expandable fusion implant may include upper and lower endplates configured to engage adjacent vertebrae and an actuator assembly for expanding the upper and lower endplates to independently control anterior and posterior heights of the implant. The actuator assembly may be operated in two modes: (1) to force the upper and lower endplates apart resulting in parallel expansion; and (2) to increase the anterior height of the implant resulting in an increase in lordotic angle.

A glenoid implant including a base plate and an articular component. The base plate can include a body and a support structure extending from a distal surface of the body. The body can include a plurality of openings. The articular component can be configured to removably couple to the base plate. The articular component can include a recessed portion configured to at least partially receive the body of the base plate. At least one engagement structure can protrude from a distal facing surface of the recessed portion. Each engagement structure can correspond to one of the plurality of openings in the body. A distal face of the articular component surrounding the recessed portion can be configured to abut the subchondral bone.

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.
