Abstract: A bone stabilizing plate includes two plate portions, each affixable to bones of a patient, the plate portions telescoping together with mating rails and grooves. A limiter associated with one of the plate portions sliding engages one a catch associated with the other of the plate portions, when the plate portions are telescoped together, and resists stops telescoping when the plate portions are telescoped a predetermined distance apart. Once the limiter and catch are engaged, the plate portions enable imposition of a minimum compressive force between bones connected to the plates. The limiter is resiliently positioned to deflect into a relief formed in its respective plate portion. A groove positioned proximate the catch enables free telescoping motion limited by the engagement of the catch and limiter, whereby the minimum compressive force between bones is maintained, and Wolfe's Law may apply.

Abstract: An expandable prosthetic implant for engagement between vertebrae includes a first member having a first end, a second end, a plurality of extensions and and a hollow interior portion extending from the first end to the second end, wherein the plurality of extensions extend from the first end to the second end. A second member includes a first end, a second end, a hollow interior portion extending from the first end to the second end, and a plurality of extensions extending from the second end to the first end. The plurality extensions of the first member are configured to coaxially interdigitate with the second member, and the plurality of extensions of the second member are configured to coaxially interdigitate with the first member. The first member of the implant is moveable relative to the second member along a longitudinal axis.

Abstract: Expandable fusion devices, systems, instruments, and methods thereof. The expandable fusion device is capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. The fusion device may include a body, a first endplate, and a second endplate. A drive screw may be rotated to move the first and second endplates outwardly and into an expanded configuration. Instruments may be provided to ensure the implant is inserted safely and as intended.

Abstract: The present invention relates to an expandable implant for engagement between vertebrae generally comprising an inner member, outer member, and gear member positioned coaxial with respect to each other such that the inner and outer members are moveable relative to each other along an axis. The gear member is axially fixed to the outer member and freely rotatable with respect to the outer member and the gear member threadedly engages a threaded portion of the inner member to translate inner member along the axis. The implant is configured to engage the vertebrae in a predetermined alignment and the gear member includes gear teeth exposed to the exterior and configured to be accessible by a tool member at a plurality of angular positions around the perimeter of the implant device.

Abstract: Embodiments herein are generally directed to vertebral implants and implant trials for use with vertebral implant assemblies. In some embodiments, these implants and implant trials may be used in conjunction with corpectomy procedures.
