A prosthetic implant for engagement between first and second vertebrae. The implant includes a first plate configured for attachment to the first vertebrae and defining a first interbody connection member and a second plate configured for attachment to the second vertebrae and defining a second interbody connection member. An interbody component includes a body with a first end defining a first plate connection member configured for connection to the first interbody connection member and a second end defining a second plate connection member configured for connection to the second interbody connection member. A method of inserting the implant is also provided.

The present disclosure relates to an expandable interbody that includes superior and inferior shells enclosing a control mechanism that includes interlocking proximal and distal cages as well as an adjustment screw that longitudinally translates the distal cage relative to the proximal cage and thereby expands interbody by pushing apart the distal ends of the superior and inferior shells.

An implant for restoring height of a vertebral body. The implant includes upper and lower plates configured to be moved away from one another in the craniocaudal direction for the implant to be deployed. Supports are coupled to the upper plate and a distal end portion, and arranged in a crisscross configuration in the proximal-to-distal direction in each of an insertion configuration and a deployed configuration. The crisscross configuration facilitates increased expansion of the implant. The supports may be laterally spaced from one another to define a void space for receiving retaining element, and inner and outer arcuate surfaces may provide a generally cylindrical profile to the implant. One of the supports may be a support fork arranged in a V-shaped configuration. A length of the supports may be approximately 50-90% of a length of the upper and lower plates. The implant may be formed through additive manufacturing.

Proposed is a vertebral cage including a body which is inserted between a vertebra and a neighboring vertebra, and is provided with a space part that can be filled with bone powder; a blade which is rotatably provided on an inner side surface of the body. The cage also includes a locking means which fixes the blade, which has or has not been rotated on the body, on the inner side surface of the body, wherein the locking means comprises fixing protrusions and groove parts which are provided on mutually facing surfaces of the body and the blade, and coupled to each other.

An interbody system including an implant and a tool for inserting and expanding the medical implant and locking the implant in place is disclosed. The medical implant may include an expandable body defined by a superior endplate and an inferior endplate that are hingedly coupled and may be expanded and lordosed. The superior and inferior endplate may include radially disposed and opposed surfaces that mate and/or directly contact each other when a locking screw is threaded through a screw aperture. The implant may include a threaded breakoff screw disposed in the threaded screw aperture and movable between a locked position and an unlocked position, for example. In the locked position, the threaded locking screw may urge the distal engagement surface of the first core into direct contact with the proximal engagement surface of the second core. When broken, the breakoff screw may comprise a recessed fracture surface.

An expandable implant may include an expandable body defined by a superior endplate and an inferior endplate that are hingedly coupled and may be expanded and lordosed by an external surgical tool. The superior endplate may include a first core having a distal engagement surface and the inferior endplate may a second core having a proximal engagement surface and a threaded screw aperture. The implant may include a threaded locking screw disposed in the threaded screw aperture and movable between a locked position and an unlocked position, for example. In the locked position, the threaded locking screw may urge the distal engagement surface of the first core into direct contact with the proximal engagement surface of the second core. The implant may include a pair of mounting tangs that may be sheared off and/or recesses. The locking screw may be a break-off screw.

An expandable implant may include a superior endplate and an inferior endplate hingedly coupled together. The superior endplate may have at least one track extending in a proximal-to-distal direction and an inferior endplate may have at least one track extending in the proximal-to-distal direction. The implant may further include a proximal plate having a superior engagement surface and an inferior engagement surface. At least one shim may be disposed within the at least one tracks of the superior endplate and interior endplate, and the at least one shim may define an angle of inclination between the superior endplate and interior endplate. The at least one shim may be insert between the superior and inferior endplates to effectuate expansion and angulation. In various embodiments, the superior endplate may be supported by the superior engagement surface and the inferior endplate may be supported by inferior engagement surface.

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.

An expanding, conforming interbody implant includes a plurality of superior and a plurality of inferior segments. The segments are adapted to individually expand, contact, and conform to endplates of vertebral bodies to distribute forces equally over the implant and across the vertebral endplates. Once a proper extension of the segments has been achieved, the segments are locked in position. The implant has a stiffness that approximates the stiffness of bone, and the implant minimizes problems with subsidence, endplate fractures, and stress shielding.

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.
