<p>A modular spinal plate assembly for use with modular polyaxial pedicle screw implant devices (102) includes a track portion having a pair of parallel rails (152a, 152b) and a multiplicity of compressible coupling elements (122), each having a through hole through which a post portion (112) of a modular polyaxial screw (102) may be mounted. The coupling elements (122) include slots, oppositely oriented, on either side of the element, which slots may be compressed to effectuate the deflection and compaction of the coupling element when a compressive load is applied. This load is applied by a top locking nut (220). The load causes the coupling element (122) to be compression locked to the rails (152a, 152b).</p> |
