Abstract:
A polyaxial bone screw assembly includes a threaded shank body having an upper portion with a capture structure thereon, a retaining and articulating structure, a compression structure and a receiver for holding the capture structure, retaining and articulating structure, compression structure and a rod. The receiver includes arms that define a channel for receiving the rod. The arms have inner surfaces with a discontinuous flange form thereon for mating with a cooperating continuous flange form of a closure structure for capturing the rod within the receiver. The shank capture structure and the retaining and articulating structure are threadably attached and secured to one another with a buttress stop. In operation, the compression structure is disposed within the receiver between the shank upper portion and a rod but presses only upon the retaining and articulating structure. The retaining and articulating structure has an external substantially spherical surface that mates with an internal surface of the receiver, providing a ball joint, enabling the receiver to be disposed at numerous angles relative to the shank body. The shank upper portion includes a tool engagement formation for driving the shank body into bone.

Claim (Index 11):
The pivotal bone anchor assembly of  claim 10 , wherein the insert does not engage the retainer below the retainer hemisphere plane when the receiver longitudinal axis and the shank longitudinal axis are co-axial.
