An expandable implant having superior and inferior endplates disposed on opposite sides of a core is disclosed. The superior endplate may include a first screw engagement surface disposed on a proximal end thereof and the inferior endplate may include a second screw engagement surface disposed on a proximal end thereof. A pin may extend through corresponding pin apertures of the superior endplate, the inferior endplate, and the core. In various embodiments, the superior endplate and inferior endplate are hingedly connected to the core via the pin. The implant may include a locking screw movable between a locked position and an unlocked position. In the locked position, the locking screw may urge an engagement surface of the superior endplate and inferior endplate such that corresponding interior surfaces of the superior and inferior endplates frictionally engage against a corresponding exterior surface of the core.

An implantable orthopedic support device and methods of using the device are disclosed. The device can have rigid structural components that can translate longitudinally with respect to each other, and in so doing can change the vertical height of the device. The structural components can be driven by a drivescrew mechanism to change the vertical height of the device.

Orthopedic implants, systems, instruments, and methods. A bi-portal lumbar interbody fusion system may include an expandable interbody implant and minimally invasive pedicle-based intradiscal fixation implants. The interbody and intradiscal implants may be installed with intelligent instrumentation capable of repeatably providing precision placement of the implants. The bi-portal system may be robotically-enabled to guide the instruments and implants along desired access trajectories to the surgical area.

An expandable vertebral body implant, and methods of assembly and using the implant. The vertebral body implant includes a body with a first end and a second end, a rotating member rotatably coupled to the first end of the body, wherein an end includes a plurality of first notches inset into the rotating member, an extension member moveably coupled to the rotating member, and a locking member positioned on an interior of the body. Methods for assembling and using the vertebral body implant are also disclosed.

Methods for securing a intervertebral cage to one or more levels of the spine with fixation. The fixation, which is typically a staple, is intended to be driven perpendicular to the proximal face of the cage and in-line with the inserter. After the cage is placed and positioned according to surgeon preference, a single piece fixation clip is then deployed and fixed in a manner that produces a zero-profile device.

In an intervertebral implant having at least two upper and two lower contact bodies that have contact surfaces. An actuator has a threaded body which has an extension axis and is provided with opposite-handed threads arranged one behind the other. Wedges sit on the threaded body in an axially moveable manner and can be moved along the threaded body by rotating the same. Ramps of at least one ramp body of a wedge engage at least with counter-surfaces of at least some of the contact bodies and extend toward one another at a finite angle of less than 90°. The wedges are double wedges having two ramp bodies arranged one behind the other, and the ramps of one ramp body are oriented differently to the ramps of the other ramp body. The ramps of the first ramp body engage directly with the contact bodies laterally.

An expandable interbody spacer for placement between adjacent vertebrae having two or more upper and lower endplates and lateral expansion wedges configured to couple a drive means to expand both a height and a width of the expandable interbody spacer from a collapsed state to an expanded state.

A cortical shaft bone fixation apparatus includes a housing having a leading portion and a trailing portion, the leading portion configured to fit within a diameter of an affected cortical shaft bone, the leading portion having first and second sections. The apparatus further includes an expansion mechanism adapted to transition the first and second sections from a first position to a second position, the first and second sections providing an outward force against the inside surface of the cortical shaft bone when the first and second sections transition from the first position to the second position, the trailing portion of the housing abutting a leading end of the affected cortical shaft bone. The trailing portion of the housing includes a pair of angled tapers extending inwardly toward each other to a minimum separation distance at an extreme end of the housing.

Provided is a novel joint replacement prosthesis that includes a base component, and one or more modular stems. The base component includes a bone-facing surface including one or more stem connectors configured for receiving and forming connections with the one or more modular stems inserted from the bone-facing surface side.

The present disclosure provides for spinal implants configured for lateral insertion techniques deployable between a contracted position and an expanded position. The spinal implant may include a first endplate and a second endplate, each having a plurality of guide walls and inclined ramps. The spinal implant may further include a moving mechanism having first and second trolleys configured to act against the first and second plurality of ramps. The moving mechanism may further include a first set screw and a second set screw opposite the first set screw. The moving mechanism may be configured to operably adjust a spacing between the first and second endplates upon simultaneous rotation of the first and second set screws along a rotation axis, and may also operably adjust an angle of inclination between the first and second endplates upon rotating the first set screw or second set screw along the rotation axis.
