Arcuate fixation members with varying configurations and/or features are provided, along with additional components for use therewith in provided fixation systems and intervertebral implant systems. The arcuate fixation members may be of varying lengths, cross sectional geometries, and/or cross sectional areas, and may be configured with various features such as heads configured to accept other fixation system components, tabs to allow arcuate fixation member-in-arcuate fixation member or fixation anchor-in-arcuate fixation member configurations. Applications of fixation systems and intervertebral implants systems utilizing arcuate fixation members are particularly suitable when a linear line-of-approach for delivering fixation members is undesirable.

Arcuate fixation member

Arcuate fixation members with varying configurations and/or features are provided, along with additional components for use therewith in provided intervertebral implants. The arcuate fixation members may be of different lengths, cross sectional geometries, and/or cross sectional areas. Applications of intervertebral implants utilizing arcuate fixation members are particularly suitable when a linear line-of-approach for delivering fixation members is undesirable.

An intervertebral spacer implant () is provided with a retention mechanism () to help alleviate expulsion and movement of the implant when placed in the spine while providing an implant that is easier to insert in the spine. In one embodiment the retention mechanism comprises a keel on at least one of the inferior or superior faces of the spacer implant preferably extending in an anterior-posterior direction. In another embodiment the implant comprises a spacer () and a plate (), the plate comprising a supplemental or alternative retention mechanism. In one embodiment the retention mechanism comprises one or more holes () in the anterior end of the plate. In yet another embodiment, the retention mechanism comprises one or more blades that are in a first position when inserted and are preferably rotated to a second position that engages the superior and inferior vertebrae.

Intervertebral implant with fixation geometry

An adjustable intervertebral implant for implantation into a patient's spine in-between first and second adjacent or neighboring vertebrae. The implant may include one or more of the following features: (i) inner and outer members coupled by a radiographically imagable expansion ring, (ii) detachable endplates coupled to the implant via a polygonal press-fit coupling interface that accommodate a range of lordotic endplates to be applied to the implant using any surgical approach, (iii) an interference pre-loaded set screw for selectively locking the height of the construct, (iv) a radiographically imagable marker for determining the expansion of the implant, and (v) an asymmetric thread coupling between the expansion ring and the inner member.

Adjustable intervertebral implant

The present disclosure relates to a spinal implant or spacer that addresses the variation in anatomy of vertebrae along the spine by having inferior and superior surface angle and convexity variations that are adapted to address the differences in lordosis and endplate surface convexity of the spine. The difference between the convexity of the superior and inferior surface of the spacer increases as the lordotic angle of the spacer increases. The spacers described herein thus provide overall improved fit into vertebral disc space and in some embodiments are even used in the absence of fusion for a prolonged period. The vertebral spacers described herein in some embodiments are used with supplemental internal fixation systems, such as an anchor plate. The interior of the spacer has channels and undercuts to increase graft volume and retention, support bony ingrowth, and bony stability for better secondary and tertiary stabilization.

Vertebral body replacement or fusion device

One embodiment of the present invention is directed to a bone plate assembly that includes a bone plate, bone screw(s) received in aperture(s) in the bone plate, and screw fixation member(s). The screw fixation member(s) may, alone or in conjunction with the bone plate, fix the bone screw(s) in place when such bone screw(s) are inserted in the aperture(s) in the bone plate. In one example (which example is intended to be illustrative and not restrictive) when the bone screw(s) have been received by the bone plate and inserted into bone and/or tissue, the bone plate assembly can-be used to fuse anatomical structures together (such as adjoining bones) and/or to heal a fracture in bone.

Functionality is described for reducing the unauthorized reproduction of optical media, such as optical discs of various types. The functionality operates by adding a physical descriptor to an optical medium, forming reference descriptor information based on the descriptor, signing the reference descriptor information to produce authenticity information, and adding the authenticity information to the optical medium. At a point of consumption, the functionality operates by reading the authenticity information and reading the descriptor. Based on the information that is read, the functionality performs cryptographic analysis and descriptor-based analysis to validate the optical medium. The functionality includes various provisions to reduce the impact of wear and tear on the above-summarized analysis. The functionality can be applied to stamped or recordable optical media.
