Abstract:
A modular polyaxial bone screw includes a poly-axial bone screw, a polyaxial tulip head, and a collet disposed within the tulip head, the collet interacting with the bone screw and tulip head providing an interference fit with the bone screw head to lock orientation of the tulip head on and relative to the bone screw. Inner configurations of the tulip head interact with outer configurations of the collet to lock axial and/or rotational position of the collet within and relative to the tulip head, and thus about the bone screw head. The collet also has a resilient, tapered base with a plurality of slots in and about its end that allow the end to splay outwardly over and upon the head of the bone screw to create a snap or frictional interference fit between the splayed collet and the bone screw head when a spine rod is fixed in the tulip head.

Claim (Index 10):
A modular bone screw comprising:\n a polyaxial bone screw having a threaded shank and a rounded head; a tulip head disposed on the rounded head of the polyaxial bone screw and configured to swivel about the rounded head of the polyaxial bone screw before the polyaxial bone screw head is fixed in spatial orientation relative to the polyaxial bone screw, and to receive and hold a spine rod in spine rod notches disposed in a first end of the tulip head once the spatial orientation of the polyaxial bone screw head is fixed, the tulip head having a bore extending from the first end to a second end of the tulip head that also defines an interior with an inner wall within the tulip head, and an inner configuration disposed in the inner wall; and a collet disposed in the interior of the tulip head, the collet having a tapered first end resting upon the rounded head of the polyaxial bone screw and having a plurality of cutouts configured to allow the tapered first end of the collet to splay about the rounded head of the polyaxial bone screw and fix the spatial orientation of the tulip head through interference between the tapered first end, the rounded head of the polyaxial bone screw, and the tulip head when a spinal rod is received in and affixed to the polyaxial bone screw head, the tulip head having an outer configuration on an outer wall that cooperates with the inner configuration of the tulip head to fix axial and rotational position of the collet relative to the tulip head.
