Bret Ferree: Cross-coupled vertebral stabilizers. Gifford Krass Groh Sprinkle Anderson & Citkowski PC, June 19, 2001: US06248106 (276 worldwide citation)

Spinal stabilization mechanisms act to prevent lateral bending, extension, and rotation at the disc space. Two or more anchors at each vertebral level, and links at each level to both anchors at the other level result in a cross-braced arrangement that enhances compression and promotes fusion. In th ...
