Abstract: Disclosed is a standalone anterior cervical interbody spacer that includes a spacer body and cervical plate with a unique locking system rigidly couple the spacer body and cervical plate via two flexible locking pins. The locking system include locking features designed to engage with one or more flexible locking pins to lock the spacer body and cervical plate together. The locking features are part of the engagement arm or engagement protrusion with a locking pin engagement surface having distraction geometry and lock geometry. The distraction geometry includes an inclined or ramped portion and the lock geometry includes a pin engagement recess or pocket. The distraction geometry is such that as the spacer body and cervical plate are coupled, the inclined or ramped portion will engage and force the flexible pin to deform and slide on the surface.

Abstract: An expandable interbody spacer for placement between adjacent vertebrae having two or more upper and lower endplates having compound-angle linear rods coupled to compound-angle bores configured to couple with the compound-angle linear rods a drive means having corresponding compound-angle slots, ramps or rails configured to slidingly engage the compound-angle slots, ramps or rails of the two or more upper and lower endplates, wherein movement of the drive means in a first direction moves the two or more upper and lower endplates away from each other both vertically and horizontally to expand both a height and a width of the expandable interbody spacer from a collapsed state to an expanded state.

Abstract: A stylet screw driver assembly having a screw driver / ratcheting handle assembly which houses a stylet, pre-assembled to a set length based on the screw length in use, fixed in place by a spring loaded button mechanism located on the proximal end of the ratcheting handle. The spring loaded button mates with the stylet assembly, providing various stylet protrusion lengths.

Abstract: A fastener retention system for a standalone interbody spacer that includes flexible members to configure to rotate from an "unlocked to a "locked" state to cover the screw holes in the interbody space to prevent bone engagement fasteners from backing out. The fastener retention system is actuated with a driver device which is provided in the instrumentation system. The fastener retention system consists of one or more flexible members or flexible locking pins, for example, nitinol pins, pressed into bores on the plate component. The flexible members are forced into single shear deflection via a revolving cam barrel which is rigidly affixed to the cam head. The revolving barrel contains radial locking pin pockets that interface with the flexible members and create defined 'clocked' positions for the cam head.
