Abstract: Methods, systems and apparatuses are provided for torsionally stabilizing a spinal motion segment. One or more implants are placed between two vertebrae to provide torsional stabilization. In particular, one or more implants may be fixed between a superior vertebral body, such as at the spinous process, and an inferior vertebral body. The implants may be connected to the superior vertebral body using a fixation device such as a turnbuckle, an outrigger, a thimble, an endobutton, a suture plug or combinations thereof. The implant may also be connected to the inferior vertebral body using various types of hardware, including staples, screws and anchors. The implant may be kept in tension to provide torsional stabilization and may be comprised of one or more sutures. A multi-functional instrument having one or more arms having holes can be used to clamp onto the superior vertebral body and guide one or more implants to various locations for fixation in accordance with the methods described herein.

Abstract: A spinal implant as provided having a porous body that includes a leading end, a convex trailing end and first and second sides extending between the leading and trailing ends. At least a portion of the leading end is generally straight. The body further includes a generally dome-shaped superior surface and a generally planar inferior surface. The superior surface is convex between the leading and trailing ends and is convex between the first and second sides.

Abstract: A device for facilitating bone fusion of two vertebrae. The device is sized and shaped to at least extend between the two vertebrae to be fused, and includes an outer wall member disposed about an inner portion. A space between the outer wall member and the inner compartment is adapted to contain an osteogenic bone fusion material. The inner portion includes a compartment adapted to contain an inner fill material, such as a bone cement or an in situ curable polymer. The inner portion may operate as a structural member to maintain a desired amount of spacing between the vertebrae to be fused, and to support the spinal column prior to formation of the fused bone joint. The device is also configured to locate the osteogenic material away from the centers of the vertebrae to be fused, providing a fused joint with high bending and torsional rigidity.

Abstract: The present disclosure concerns implants to at least partially replace the nucleus of a spinal disc. In one embodiment, a prosthetic implant is provided which includes a bag structure having a fixation component or member, the bag operable to contain at least one internal implant within the bag. In other embodiments, a bag structure is provided with a flange adaptable to anchor the structure to a vertebral body and a sinusoidal-shaped structure made of a flexible material is provided with various unique configurations. In one embodiment, for delivery, a bag structure with a flange may be attached to a vertebral body. In another embodiment, a sinusoidal-shaped implant structure is alternately woven from one end to the other with a second sinusoidal-shaped structure.
