Abstract
An improved device and a method for stabilizing lumbar vertebrae in a human spine for the purpose of fixing the vertebra with respect to other vertebra and with respect to other parts of the spinal column. This device comprises a plate, bone screws, bone screw clamp portion, spacers, and rigidizing stop locks. The bone screw clamps may be clamped firmly to the plate for a fully rigid system. Alternatively the screw clamp portions may be held apart, with clearance between them and the plate, which will allow for axial motion of the screw with respect to the plate for implant load sharing and dynamized motion.
