Abstract:
A medical implant assembly includes a polyaxial bone anchor having a shank, a receiver, a lower compression insert with surfaces for closely receiving an elongate connecting member and a dual closure structure that may include a single flange or helical flange. The dual closure structure independently engages the connecting member and the lower compression insert. A threaded capture connection of the bone anchor includes a shank upper surface exclusively engaging the lower compression insert and a retainer threadably attached to the shank and spaced from the upper surface, the retainer configured for polyaxial motion with respect to the receiver prior to locking.

Claim (Index 27):
A pivotable bone anchor assembly for securing an elongate rod to a bone via a closure top, the pivotable bone anchor assembly comprising:\n a receiver comprising a lower body with a bottom opening having a first thread formed therein, and an upper portion having a channel for receiving the elongate rod, the lower body defining an internal cavity in communication with the channel and with a bottom surface of the receiver through the bottom opening, the internal cavity being partially defined by a lower supporting surface adjacent the bottom opening having a first thread formed therein; an anchor member comprising a proximal end portion, a distal end portion, and a central aperture extending entirely through the anchor member along a central longitudinal axis of the anchor member and opening onto a top end and a bottom end of the anchor member, the proximal end portion including a lower outer curved contact surface that is engageable with the receiver cavity lower supporting surface and a second thread formed above the lower outer curved contact surface; and an insert at least partially positionable within the channel and having an upper surface configured to receive the elongate rod and a lower surface configured to engage a top surface on the anchor member proximal end portion, wherein the anchor member proximal end portion is positionable within the internal cavity of the lower body of the receiver such that the anchor member outer curved contact surface is slidably engageable with the receiver cavity lower supporting surface so as to establish pivotable motion between the anchor member and the receiver while preventing the anchor member proximal end portion from exiting the internal cavity through the bottom opening.
