Abstract
The present application generally relates to orthopedic systems, and in particular, to systems including independent plates and spacers. A plating system can include a spacer and a plate that is independent from the spacer. A number of locking mechanisms can be provided to secure the plate to the spacer. In some cases, the spacer includes a pair of notches that extend on an outer surface of the spacer. The plate can include a pair of lateral extensions that can engage the notches to secure the plate to the spacer. In other cases, the spacer includes an opening including a pair of inlets. The plate can include an enclosed posterior extension that can be received in the pair of inlets to secure the plate to the spacer.
Claims19
A spinal system comprising:
- a plate member including an upper rim and a lower rim, the plate member further including a first arm and a second arm, the first arm and the second arm each including at least one window;
- a spacer having first and second lateral sides, the first and second lateral sides defining the width of the spacer, wherein the spacer attaches to the plate member by engaging the first lateral side of the spacer with the at least one window in the first arm and engaging the second lateral side of the spacer with the at least one window in the second arm;
- a first screw upwardly insertable through an upper screw hole of the upper rim;
- and
- a second screw downwardly insertable through a lower screw hole of the lower rim, wherein protrusions on the spacer are configured to fit in the at least one window of the first arm and the second arm.
A plate configured to fixate two adjacent vertebral bodies, the plate comprising:
- a body;
- an upper rim extending from the body and a lower rim extending from the body, wherein the upper rim includes an upper screw hole extending through the upper rim and having an upper screw hole center axis and the lower rim includes a lower screw hole extending through the lower rim and having a lower screw hole center axis;
- a first screw insertable through the upper screw hole, wherein the first screw is oriented in an upward direction;
- and
- a second screw insertable through the lower screw hole, wherein the second screw is oriented in a downward direction;
- wherein the body comprises a first window and a second window configured to attach the body to a spacer, and
- wherein the upper screw hole center axis is positioned entirely above an upper surface of the spacer and the lower screw hole center axis is positioned entirely below a lower surface of the spacer,
- wherein protrusions on the spacer are configured to fit in the first window and the second window of the body of the plate.
