  • Publication number: 20210106434
    Abstract: An expandable implant is disclosed in which the implant includes top and bottom plates having angled inner surfaces that interact with expansion members. The expansion members may be situated on an actuator, and may include at least one vertical projection. In some instances, rotation of the actuator in opposing directions about a longitudinal axis may cause the expansion members to move toward or away from one another, thereby resulting in separation of the top and bottom plates. During such expansion of the implant, the at least one vertical projection of the expansion members may be guided at least partially within a recess formed in the first or second plate. Pins may also be included with the expansion members that ride along respective slots in the plates during expansion. An insertion instrument for implanting the aforementioned implant, and methods of using the same, are also disclosed.

  • Patent number: 10080668
    Abstract: A method for fusing vertebral bodies comprising the steps of: mounting a first engagement member of a fixation member to a pedicle of a first vertebra and a second engagement member of the spinal fixation member to a pedicle of a second vertebra, the first engagement member having a first extension engaged with an expansion ring, the second engagement member having a second extension engaged with the expansion ring; inserting screws through the first and second engagement members and into the pedicles of the respective first and second vertebrae; rotating the expansion ring in a first direction, thereby distracting the first and second vertebrae; implanting an intervertebral implant between the first and second vertebrae after rotating the expansion ring in the first direction; and rotating the expansion ring in a second direction after implanting the intervertebral implant, thereby compressing the first and second vertebrae.

  • Patent number: 9867713
    Abstract: A prosthetic intervertebral spacer includes a body having a front end, a rear end, an anterior side, a posterior side, a top surface, and a bottom surface, and an arcuate interface extending away from the body and being connected to the rear end and the posterior side of the body. A method of inserting and positioning the spacer includes engaging a tool to the interface, inserting the spacer at least partially into the intervertebral disc space by moving the tool along an insertion direction, and allowing the spacer to rotate with respect to the insertion direction within the intervertebral disc space while continuing to move the tool along the insertion direction.

  • Patent number: 9320610
    Abstract: An expandable implant (210, 410) includes top and bottom plates (220, 250, 420, 450) having angled inner surfaces (222, 252, 422, 452) that interact with expansion members (300, 302, 500, 502). The expansion members (300, 302, 500, 502) may be situated on an actuator (280, 480), and may include at least one vertical projection (312, 314, 512, 514) for interacting with a recess (230, 430) in the plates (220, 250, 420, 450). In some instances, rotation of the actuator (280, 480) in opposing directions about a longitudinal axis may cause the expansion members (300, 302, 500, 502) to move toward or away from one another, thereby resulting in separation or collapse of the top and bottom plates (220, 250, 420, 450). Pins (316, 516) may also be associated with the expansion members (300, 302, 500, 502) and received in respective slots (318, 518) in the plates (220, 250, 420, 450).
