Abstract
A pedicle screw is provided that includes an upwardly extending collet. The collet may include downwardly extending slots that define deflectable segments therebetween. 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 may be interposed between the collet and the spherical element to facilitate positioning therebetween. In an alternative embodiment, a non-slotted collet is employed. In such embodiment, the collet and the spherical element may be threadingly engaged and may include a snap ring therebetween. The pedicle screw subassemblies may be incorporated into a spinal stabilization system which may include a dynamic stabilizing member to provide clinically efficacious results.
