Modular spinal plate for use with modular polyaxial locking pedicle screws

摘要: A modular spinal plate assembly for use with polyaxial pedicle screw implant devices includes a track portion having pair of parallel rails and multiplicity compressible coupling elements which are slideably mounted about the rails. The each have through hole post may be mounted. In addition, include slots, oppositely oriented, on either side element, slots compressed to effectuate deflection compaction element when compressive load is applied. This applied by top locking nut being advanced along screw, downwardly onto element. subsequent causes compression locked rails, thereby becoming rigidly fixed at specific position axial extent Multiple portions sequential screws coupled same via multiple relative immobilization sequence vertebral bones.
