Abstract: Disclosed is a spinal interbody spacer that includes a spinal spacer body with an asymmetrical open end, an asymmetrical screw fixation plate configured to couple with the asymmetrical open end, and a locking mechanism configured to lock the screw fixation plate and the spinal spacer body together.

Abstract: A minimally invasive intervertebral implant includes a circuitous body defining a luminal axis extending longitudinally therethrough. The circuitous body includes proximal and distal ends oppositely disposed along a lateral axis of the circuitous body. Each of the proximal and distal ends includes an aperture disposed therethrough such that the circuitous body includes a first configuration wherein the proximal and distal ends are at a maximum separation and a second configuration wherein the proximal and distal ends are closer together than in the first configuration.

Abstract: An expandable lateral lumbar interbody spacer for placement between adjacent vertebrae configured to have a collapsed state suitable for insertion into an intervertebral space between a pair of adjacent vertebrae, and an expanded state that includes lordosis change during vertical expansion.

Abstract: An expandable interbody spacer that is delivered in the anterior approach with adjustable height and end plate angulation (lordosis). The expandable interbody spacer is configured to have an initial collapsed state having a first height suitable for being inserted into an intervertebral space defined by a pair of adjacent vertebrae, and an expanded state having a second height that is greater than the first height. The expandable interbody spacer may be expanded from the initial collapsed state to the expanded state in-situ. The expanded state increases the distance between the adjacent vertebrae and provides support to the adjacent vertebrae while bone fusion occurs and also provides rigid support between the adjacent vertebrae that withstands compressive forces.

Abstract: 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.

Abstract: A variable lordosis endplate that may adjusted from 0 to 30 degrees using a mechanical drive that allows the spine's angle to be physically adjusted in-situ. The variable lordosis endplate may be quickly attached to either end, or both ends, of the central column. The variable lordosis endplate can be attached in orientations of every 15 degrees. The variable lordosis endplates' lordotic angles may be on either end of the column independently from one another. By attaching a variable lordosis endplate to both ends of the column, hyper-lordotic angles may be achieved.

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: An En Bloc connector configured to couple with multiple sequential reducers or extenders, such as spinal screw reducers, to correct a rotation deformity of the spine by turning or rotating the deformed spine structure toward a normal position. In the embodiments shown, the En Bloc connector holds three sequential reducers in the retracted configuration and four sequential reducers in the extended configuration.

Abstract: A fixation member inserter instrument attaches to an interbody spacer and assists in the insertion of the interbody spacer into the intravertebral spacer. The distal end of the fixation member inserter instrument includes a fixation member guide with two or more fixation members that is configured to simultaneously deliver the two or more fixation members during the fixation member impaction process. The interbody spacer is attached to the inserter instrument by a threaded rod adjacent to the main body of the fixation member inserter instrument. There is an impaction rod extending through the device which connects to the two or more fixation members in the fixation member guide. When the impaction rod is impacted on a proximal end, the distal end contacts the two or more fixation members simultaneously and forces them into the vertebral body at the same time.

Abstract: A tissue retractor having a spring loaded retractor blade that provides constant downward pressure on the spine to eliminate/reduce tissue from creeping underneath the tips of the blades during use, which decreases operation time and reduces patient risk.

Abstract: An expandable cage for placement between adjacent vertebrae having two or more upper and lower end plates having compound-angled slots, ramps or rails, and a drive means having corresponding compound-angled slots, ramps or rails configured to slidingly engage the compound-angled slots, ramps or rails of the two or more upper and lower end plates, wherein movement of the drive means in a first direction moves the two or more upper and lower end plates away from each other both vertically and horizontally to expand both a height and a width of the expandable cage from a collapsed state to an expanded state.

Abstract: A vertebral body replacement system having a quick-connecting removable endplate connection mechanism.

Abstract: 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.

Abstract: The present invention is directed to a rod reducer that is both a lateral rod reducer and an axial rod reducer that uses an entirely different mechanism never before used for lateral rod reduction. The lateral rod reducer is configured to move a spinal fixation rod that is not aligned with the pedicle screw to a position above the tulip slot or U-shaped channel. Once in position, the lateral rod reducer also provides an axial rod reducer to advance the spinal fixation rod axially into the tulip slot. Splitting the reducer body geometry to create a hinged jaw that is then driven by a linkage system is novel. The lateral rod reducer of the present invention allows for incremental lateral reduction that utilizes a threaded linkage feature for increased power/mechanical advantage when laterally reducing. This will allow for new techniques of lateral rod manipulation in deformity cases.

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

Abstract: A tissue retractor having a bevel gear driven retractor blade that features a tool-less coarse adjustment that allows a single surgeon to easily manipulate and secure the orientation of a retractor blade while preparing the surgical corridor.
