Abstract
An anti-subsidence, anti-translocation, fusion compression cervical plate system with interface visualization, drill guide and temporary pin is provided. In one embodiment the invention provides a vertebral plate for minimizing the ability of an inter-body cage, filled with bone (or BMP-soaked sponges, etc.), to telescope into the vertebral body and to minimize failure due to cages that telescope into adjacent vertebral bodies on a delayed basis after surgery, as well as creation of reverse lordosis due to such telescoping. Another embodiment provides method to reduce the gap between the inter-body cage and the vertebral body end plate intra-operatively using compression from the plate caused by an offset between the screw bores on the plate and the drill holes, as established with an asymmetric drill guide.
