Abstract:
A translating polyaxial bone anchor for anchoring a connecting rod to a spinal vertebra comprises a fastener having a bone engaging portion and a head, the head defining a socket. An insert is captively retained in the socket and configured for swiveling polyaxial movement therein. The insert includes an elongate connecting element defining an axis, the connecting element projecting outwardly from and through the socket. A yoke having at one end a rod receiving channel for receiving a connecting rod is coupled to the fastener by a coupling member. The coupling member couples the yoke to the insert connecting element for joint polyaxial movement relative to the fastener and for translational movement of the yoke in a direction transverse to the axis of the connecting member. A fastening element is supported by the yoke for securing the connecting rod between the fastening element and the coupling member.

Claim (Index 1):
A translating polyaxial bone anchor assembly for anchoring an elongate connecting rod to a vertebra of a spine, comprising:\n a fastener having a bone engaging portion and a head having an outer surface; a yoke having at one end a rod receiving channel defining an axis for receiving an elongate connecting rod and an opposite end including an engagement configuration; a coupling assembly coupling said yoke to said fastener in a manner that provides joint polyaxial movement of said yoke relative to said fastener and translational movement of said yoke in direction transverse to said axis of said channel, said coupling assembly comprising a collar and a slider, said collar comprising a base having an upper surface, a lower surface and an opening extending therethrough, said upper surface supporting said slider, said slider having an opening comprising a configuration substantially matching the configuration of and in sliding engagement with said outer surface of said head of said fastener, said collar comprising spaced opposing surfaces projecting upwardly from said upper surface of said base and defining a recess therebetween; said slider comprising a generally flat plate having an opening extending therethrough, said slider opening being in alignment and communication with said collar opening, said collar being supported within said recess on the upper surface of the base of said collar, said slider including a mateable configuration for cooperative mating with the engagement configuration of said yoke in a manner that slidably couples said yoke with said slider and enables translational movement of said yoke on said slider in a direction transverse to said axis of said channel; and a fastening element supported by said yoke for securing said elongate connecting rod in the channel of said yoke between said fastening element and said coupling assembly.
