Abstract: Devices and methods are provided for spinal disc replacement. A plate can be configured to couple to an intervertebral cage disposed in an intervertebral space. The plate can be modular. For example, the plate can have a first receiving portion angled relative to a second receiving portion. The first receiving portion receives a first bone screw or bone blade to engage a first vertebra, and the second receiving portion receives a second bone screw or bone blade to engage a second vertebra. A retention member can be coupled to the plate. The retention member is configured to block first and second bone screws or bone blades from backing out of the plate.
