摘要:
The present invention is directed to a system for anterior fixation of the spine that utilizes an elongated fixation plate. The plating system stabilizes the spine and promotes fusion and incorporation of a graft or implant in a portion of the spinal column. In one aspect of the invention, the fixation plate has a first end with a pair of holes. Bone screws extend through the holes to rigidly secure the plate to a first vertebra. The second end of the plate is provided with a pair of slots through which bone screws extend for engagement with a second vertebra. The screws extending through the slots are translatable in the slot to maintain compression of the spinal column portion. The plating system includes a retainer assembly that prevents screw back out. Methods and instruments relating to the plating system are also described.

Systems for stabilizing the spine and facilitating placement of stabilization devices on the spine include one or more holding elements positionable in corresponding ones of one or more cannulated auxiliary elements of the stabilization device. The holding elements can be configured to manipulate and/or maintain alignment of the corresponding auxiliary element relative to the stabilization device. A driving tool engaged to the holding element facilitates remote manipulation. The systems can further be provided with blocking members engageable to the cannulated auxiliary elements to enhance engagement of the stabilization device with the spine and to facilitate revision surgery.
