An expandable interbody spacer for placement between adjacent vertebrae having two or more upper and lower endplates and lateral expansion wedges configured to couple a drive means to expand both a height and a width of the expandable interbody spacer from a collapsed state to an expanded state.

Expandable articulating transforaminal lumbar interbody spacer

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.

Expandable interbody spacer

A standalone anterior cervical interbody spacer (ACIF) that includes a spacer body and plate rigidly couple via flexible pins.

Standalone anterior cervical interbody spacer

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.
