International Classification:

A61F 2/44

US Classification:

623 1716

Abstract:

An implant for insertion into a disc space between vertebrae, wherein the implant includes a spacer portion, a plate portion coupled to the spacer portion, two bone fixation elements for engaging the vertebrae and a retention mechanism for preventing the bone fixation elements from postoperatively backing-out of the plate portion. The retention mechanism may be in the form of a spring biased snapper element that is biased into communication with the bone fixation elements so that once the bone fixation element advances past the snapper element, the snapper element is biased back to its initial position in which the snapper element interfaces with the bone fixation elements. Alternatively, the retention mechanism may be in the form of a propeller rotatable between a first position in which the bone fixation elements are insertable to a second position where the bone fixation elements are prevented from backing-out.

International Classification:

A61F 2/44

US Classification:

623 1716

Abstract:

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.

International Classification:

A61B 17/70

US Classification:

606246

Abstract:

A posterior vertebral plating system comprising a plate and a plurality of attachment members. The plate has a plurality of holes extending through the plate from an upper surface to a lower surface, and the plate is configured to extend along the posterior side of at least two vertebrae adjacent at least one boney structure of each of the vertebrae. The holes are spaced in such a way that a first plurality of holes is positionable over a boney structure of a first vertebra to define a plurality of fixation points to the first vertebra and a second plurality of holes is positionable over boney structure of a second vertebra to define a plurality of fixation points to the second vertebra. The attachment members are insertable through the holes of the plate and into the boney structure of a corresponding vertebra to fix the plate to the vertebra.
