Abstract:
A medical implant assembly includes a polyaxial bone anchor having a shank, a receiver, a lower compression insert with planar surfaces for closely receiving an elongate connecting member with planar surfaces and a one-piece closure structure. The connecting member is made from a polymer. The closure structure engages both the connecting member and the insert with the engagement between the closure structure and the insert securely locking the polyaxial mechanism even if the connecting member exhibits creep.

Claim (Index 1):
A pivotal bone anchor assembly for securing an elongate rod to a bone via a closure top, the pivotal bone anchor assembly comprising:\n a receiver having a longitudinal axis, a base, and an integral upper portion configured to receive the elongate rod, the base including a cavity in communication with a bottom surface of the base through a bottom opening to define a receiver bore centered about the longitudinal axis, the cavity having a spherical seating surface proximate the bottom opening, the receiver bore including a structure with a downwardly-facing surface; a shank having a proximal at least partially spherical shaped head and an integral anchor portion extending distally from the head for fixation to the bone, the head being positionable within the receiver cavity with the anchor portion extending downwardly through the bottom opening, the head including an internal drive structure; a pressure insert having a longitudinal axis and an upwardly-facing seating surface configured to receive at least an underside portion of the elongate rod, a central opening for a tool to pass through to engage the shank head internal drive structure, a lower surface configured to directly engage the shank head to apply downward pressure thereto, and at least one upwardly-facing planar surface perpendicular to the insert longitudinal axis and positioned radially outward from the seating surface, the pressure insert being installed into a first position within the receiver bore, wherein upon rotation of the pressure insert about the receiver longitudinal axis into a second position within the receiver bore, the at least one insert upwardly-facing planar surface is rotated under the receiver downwardly-facing surface so as to inhibit upward movement of the pressure insert within the receiver bore along the receiver longitudinal axis.
