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: The present application is generally directed to vertebral implants and implant trials for use with vertebral implant assemblies. The vertebral implants and implant trials may be used in conjunction with corpectomy procedures. One type of vertebral implant is a corpectomy device having a polyaxial endplate assembly. The polyaxial endplate assembly includes an articulatable plate member that is capable of angulation. The articulatable plate member can be fixed in place by, for example, using a clamping assembly to fix the articulatable plate member.

Abstract: Devices and methods for treating one or more damaged, diseased, or traumatized portions of the spine, including intervertebral discs, to reduce or eliminate associated back pain. In one or more embodiments, the present invention relates to an expandable interbody spacer. The expandable interbody spacer may comprise a first jointed arm comprising a plurality of links pivotally coupled end to end. The expandable interbody spacer further may comprise a second jointed arm comprising a plurality of links pivotally coupled end to end. The first jointed arm and the second jointed arm may be interconnected at a proximal end of the expandable interbody spacer. The first jointed arm and the second jointed arm may be interconnected at a distal end of the expandable interbody spacer.

Abstract: The present invention relates to a method of inserting an implant comprising providing an expandable vertebral implant. The method further may comprise providing an angling inserter tool. The angling inserter tool comprises a handle portion, a base portion, and a tip assembly, the base portion being disposed between the handle portion and the tip assembly. The method further may comprise distally advancing a central shaft of the tip assembly with rotation into an opening in the expandable vertebral implant to secure the angling inserter tool to the expandable vertebral implant. The method further may comprise positioning the expandable vertebral implant in a patient's spine. The method further may comprise for causing the tip assembly to angulate with respect to a longitudinal axis of the angling inserter tool, wherein the internal shaft is coaxial with an outer cylinder of the base portion.

Abstract: An expandable implant for engagement between vertebrae includes an inner member, an outer member, and a 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 inner member includes a longitudinal groove configured to engage a pin extending through the outer member such that the pin prevents the inner member from translating completely through the outer member and aids in alignment and limits rotation of the second endplate. Portions of the implant may be provided with a series of markings such that when the markings are aligned, the implant is aligned in a specific configuration and for a specific implantation approach.

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.
