Disclosed herein is a guide device and a driver, which allows for the preparation of an anatomic cavity for screw fixation of an implant or spacer, including the guidance for hole preparation, and guidance for insertion of screws, and or anchors, while selecting the amount of rigidity, and selecting the amount of visibility.

Inserter guide and driver system

An intervertebral implant component of an intervertebral implant includes an outer surface for engaging an adjacent vertebra and an inner surface. A keel extends from the outer surface and is designed to be disposed in a slot provided in the adjacent vertebra. This keel extends in a plane which is non-perpendicular to the outer surface; and preferably there are two of the keels extending from the outer surface which are preferably offset laterally from one another. In another embodiment, an anterior shelf is provided at an anterior end of the outer surface, and this anterior shelf extends vertically away from the inner surface in order to help prevent bone growth from the adjacent vertebra towards the inner surface. Further in accordance with disclosed embodiments, various materials, shapes and forms of construction of the component and/or keel provide various benefits.

Intervertebral implant with keel

An instrument system, associated milling or drilling guide and method include use of a trial implant of a size corresponding to an actual implant for the intervertebral space, with a milling guide mounted on the trial implant. The system also includes a cutting tool which is used to form a cutout in an adjacent vertebra.

Drilling/milling guide and keel cut preparation system

An intervertebral implant for fusing vertebrae is disclosed. The implant may have a body with curved, posterior and anterior faces separated by two narrow implant ends, superior and inferior faces having a plurality of undulating surfaces for contacting vertebral endplates, and at least one depression in the anterior or posterior face for engagement by an insertion tool. The implant may also have one or more vertical through-channels extending through the implant from the superior face to the inferior face, a chamfer on the superior and inferior surfaces at one of the narrow implant ends, and/or a beveled edge along a perimeter of the superior and inferior faces. The implant configuration facilitates transforaminal insertion of the implant into a symmetric position about the midline of the spine so that a single implant provides balanced support to the spinal column. The implant may be formed of a plurality of interconnecting bodies assembled to form a single unit. An implantation kit and method are also disclosed.

Intervertebral implant for transforaminal posterior lumbar interbody fusion procedure

A trial implant assembly is provided that includes a threaded shaft having exterior threading adjacent a distal end and a trial implant that includes a trial base having an interiorly threaded through hole couplable to the distal end of the shaft and a trial head having a superior endplate and an inferior endplate and a support connecting the superior endplate to the inferior endplate. A variety of visualization windows are provided through the trial implant as well as a variety of mechanically adjustable stops to prevent over insertion of the trial head within the intervertebral disc space.

Trial implant assembly

An intervertebral disc for placement between adjacent vertebrae comprising: an anterior side; a posterior side; a first lateral side; a second lateral side; an upper endplate having an inner surface and an outer surface, wherein the outer surface of the upper endplate is adapted for contacting a first vertebra; a lower endplate having an inner surface and an outer surface, wherein the outer surface of the lower endplate is adapted for contacting a second vertebra; and an elastic membrane extending from the inner surface of the upper endplate to the inner surface of the lower endplate and defining an inner volume that is at least partially filled with a fluid, wherein the elastic membrane is affixed to the inner surface of the upper endplate and to the inner surface of the lower endplate.
