Systems, devices and methods are provided for assisting in spinal stabilization. A
buttress plate
system is provided that can include an intervertebral spacer, a
buttress plate, a spinal screw, and an
insertion instrument. The
buttress plate is configured to extend across at least a part of an
intervertebral space to block or prevent an intervertebral spacer from backing out of the
intervertebral space when the
buttress plate is secured to the spine. The
buttress plate includes a curved plate body having an aperture therethrough for receiving a spinal screw. The
buttress plate also includes a pair of engagement members in the form of spikes to help stabilize the buttress plate relative to the spine prior to securing the buttress plate to the spine. The buttress plate can be coupled to an
insertion instrument that is used to guide the buttress plate to a desired position adjacent the spine. Once in a desired position, a spinal screw can be delivered through the
insertion instrument and through the aperture of the buttress plate to secure the buttress plate to the spine. The insertion instrument thus helps to properly position the buttress plate adjacent the spine and to deliver a spinal screw toward the aperture of the buttress plate.
