Abstract
An intervertebral insert member and an instrument for positioning the insert in a space between vertebral bodies in vivo. The insert member is advanced by the instrument into a prepared site located between adjacent vertebral bodies. Upon reaching the appropriate insertion point, the sleeve is retracted and a pivotal motion is imparted to the insert. The insert member is pivotally attached to the distal end of the delivery instrument such that it can be articulated about a pivot point that is located on the insert member until it is properly positioned. The positioning instrument is then released from the insert member and removed from the space between the vertebral bodies. An adjustment screw is available to expand the surfaces of the insert member by displacement of a wedge member within the insert.
Claims25
An implantable spinal insert, comprising:
- a body having an arcuate configuration, a top surface and a bottom surface, a convex first side and an opposite concave second side, a first curved end portion and an opposite second curved end portion,
- a first post having a threaded portion extending between said top surface and said bottom surface about which said first and second curved end portions rotate, said first post being located between said first curved end portion and said second curved end portion and closer to said concave second side than said convex first side,
- a fully bounded aperture extending through said top surface and said bottom surface, said aperture being located within said convex first side, said concave second side, said first curved end portion and said second curved end portion, and
- a slotted passageway between said top surface and said bottom surface extending through a portion of said concave second edge surface, said slotted passageway communicating with said threaded portion of said first post for engagement with threads of an instrument to facilitate rotation of said insert about said first post.

An implantable spinal insert, comprising:
- a top surface, a bottom surface, a first side and an opposite second side, a first curved end portion and an opposite second curved end portion;
- a pivot post having a threaded portion extending between said top surface and said bottom surface about which said first and second curved end portions rotate, said pivot post being located approximately centrally between said first curved end portion and said second curved end portion;
- a second post extending between said top and bottom surface, said second post being located adjacent said first curved end portion and between said pivot post and an outer surface of said first curved end portion;
- and
- a slotted passageway between said top surface and said bottom surface extending through said first curved end portion and into said second side, said slotted passageway communicating with and exposing said threaded portion of said pivot post and said second post, said threaded portion of said pivot post being exposed through said slotted passageway for engagement with threads of an instrument to facilitate rotation of said insert about said pivot post.

An implantable spinal insert, comprising:
- a one piece body having a fixed geometric arcuate configuration, a top surface and a bottom surface, a convex first side and an opposite concave second side, a first curved end portion and an opposite second curved end portion,
- a first post extending between said top surface and said bottom surface, said first post being located adjacent said first curved end portion, and a second post extending between said top and bottom surface, said second post being located between said first post and said second curved end portion, said second post being cylindrical in cross-section and defining a longitudinal axis about which said insert is pivotable, said second post including a threaded bore extending transversely to said longitudinal axis, and
- a slotted passageway between said top surface and said bottom surface extending through said first curved end portion and into said concave second side, said slotted passageway communicating with said first post and said second post, said threaded bore of said second post being exposed through said slotted passageway for engagement with a threaded pin of an instrument to facilitate rotation of said insert about said second post.
