Abstract

Spinal stabilization devices, systems and methods are provided that include at least one pedicle screw (216,218) and at least one mechanism that supports three degrees of rotational freedom relative to the pedicle screw. The mechanism may include a universal joint mechanism or a ball (236,238) and socket (232,234) mechanism. The dynamic junction is advantageously incorporated into a spinal stabilization system that includes additional pedicle screw (s ), spherical element (s) and socket member (s) . Pedicle screws are disclosed that includes an upwardly extending collet (260) . The collet may include downwardly extending slots (270) that define deflectable segments (264) therebetween. The pedicle screw may include a preloaded set screw (274) that is maintained in position by an interference is advantageously formed on the set screw to prevent dislodgement of the set screw, e.g., during shipment and/or clinical placement of the pedicle screw. When a spherical element or other structure, e.g., a non-dynamic stabilizing element, is positioned around the collet, introduction of a set screw causes outward deflection of the upstanding segments into engagement with the spherical element. A snap ring (273) may be interposed between the collet and the spherical element to facilitate positioning therebetween.
