A system and method of securing an intervertebral fusion cage within the intervertebral space between adjacent vertebra in which one or more slots are provided in an anterior surface of the cage each extending from an oversized aperture. A retention plate having a post and enlarged head is advanced into each slot via the oversized aperture and captured therein. The post is advanced to the terminal end of the plate and secured to vertebral body at its distal end by a bone screw. A locking clip is slideably positioned on the retention plate to prevent withdrawal of the bone screw. The slots preferably extend to margins of the anterior surface of the cage in, for example, the pattern of an “X” or an “H”. Sliding of the posts in the slots prevents the system from carrying the vertebral load (load shielding) and permits reduction in the intervertebral space to promote bone growth and fusion by graft material retained in the spacer.

A method of performing vertebral facet fusion by lateral approach and related devices. The lateral approach to facet fusion involves identifying the lateral mass and then introducing any of the fixation methods known or described herein laterally at one or more facets through the use of a hollow cannula. A surgical bone staple have a perforated bridge is used across the lateral facet joint where fixation is required. Where fusion is desired, a bone screw have lateral perforations of the shank is inserted through the bridge perforation at the joint to promote fusion. The staple and screw may be used in conjunction with one another or individually. The facet joint may be distracted prior to fixation to increase the foraminal space and decompress the neural structures to relieve pain. The method involves less surgical time, reduced blood loss and discomfort for the patient as compared to the posterior approach.

623 1716

A multi-piece disc replacement implant for replacing a disc removed by a discectomy including an upper plate member, a lower plate member, and an intermediate resilient member providing movement between the two plate members replicating the natural movement of the spine. The plate members are rigid and have orthogonal sidewalls forming an enclosure. The resilient member is an elastic solid or a multi-chamber balloon structure of fluid-filled sacks that collectively define a non-uniform shape such as an oblate spheroid, or a helically coiled string of beads. Such an implant is capable of supporting the compressive and cyclic loads required of a natural disc. The upper and lower plate members are cooperatively formed to selectively limit the allowable range of motion in any given direction and a provided with protrusions to be received in one or more channels cooperatively formed in the vertebrae and secured in place by a bone screw.

A multi-piece disc replacement implant device for replacing a disc removed by a discectomy including an upper plate member, a lower plate member, and an intermediate resilient member providing movement between the two plate members replicating the natural movement of the spine including flexion/extension, lateral bending, and, in some embodiments, rotation. The plate members are rigid and have orthogonal sidewalls forming an enclosure. The resilient member is an elastic solid or a multi-chamber balloon structure of fluid-filled sacks that collectively define a non-uniform shape such as an oblate spheroid, or a helically coiled string of beads. Such an implant is capable of supporting the compressive and cyclic loads required of a natural disc. The upper and lower plate members are cooperatively formed to selectively limit the allowable range of motion in any given direction. Alternate embodiments of the invention may be employed in conjunction with removal of the nucleus pulposus when removal of the annulus fibrosus (annulotomy) is not required or desirable.

606249, 606279

An interspinous process spacer and method of implantation for distraction of the vertebra including an expandable member, a self sealing percutaneous access port in fluid engagement with the expandable member and an anchor member secured to and in fluid engagement with said tubular member. The anchor member may be an arcuate channel mechanically secured to adjacent spinous process by bone screws through a plurality of slots in the legs of the channel. The port allows for adding or removing fluid from the one or more chambers or envelopes of the expandable member in order to adjust the volume of the expandable member and thus the interspinous process spacing. Subsequent to initial implantation and expansion the volume of the expandable member may be increased or decreased in a non-surgical in-office procedure in which a needle is used to add or remove fluid from the expandable member via the port and tubular member. The flowable material/fluid may be a liquid such as saline, gel such as silicone, or a viscous polymer and my further remain in a liquid state or harden to a viscoelastic state with or without additional intervention.

A method of performing vertebral facet fusion by lateral approach and related devices. The lateral approach to facet fusion involves identifying the lateral mass and introducing any of the fixation methods known or described herein laterally at one or more facets through the use of a Kirschner wire guide, a cannulated bone drill and cooperatively cannulated staple guide. A surgical bone staple have a perforated bridge is used across the lateral facet joint where fixation is required. Where fusion is desired, a bone screw have lateral perforations of the shank is inserted through the cannulated staple guide and bridge perforation at the joint to promote fusion. A staple cap and graft container for overlay grafting may be utilized for additional fusion. The method involves less surgical time, reduced blood loss and discomfort for the patient as compared to the posterior approach.

An fusion cage having a longitudinal element and two planar bendable expansion arms slideably captured in a track on opposing sides, the expansion arms expandable from a pre-implantation position adjacent to the longitudinal element to a deployed position bounding an area around the longitudinal element in which bone graft material may be packed and retained after implantation into the intervertebral space. The longitudinal element is eliminated in favor of front and back lateral tracks in which the opposing ends of the expansion arms are slideably received so as to allow expansion of the bounded areas in both a lateral and anterior-posterior direction by sliding within the channels. Expansion of the area within the bendable members may be accomplished by rotation of leaves to which the bendable members are rigidly and slideably affixed.

A surgical staple for discectomy by an anterior approach that comprises a plate with sharp-pointed projections positioned at each of four corners of the plate and extending perpendicularly there from for frictional insertion into pilot holes formed in the vertebrae, and a pair of circular apertures in the plate spaced along a centerline for insertion of bone screws. The plurality of projections may further comprise four barbed and pointed projections that a surgeon may quickly tap into the bone, thereafter securing the staple with two smaller bone screws. An Annular C shaped retention locking clip retains the bone screws and prevents counter-rotation and back out.

A pedicle screw for insertion into the pedicle portion of a vertebra and having at its exposed end a threaded rod connected in a generally parallel orientation to the longitudinal axis of the pedicle screw but laterally offset from the longitudinal axis of the pedicle screw. The threaded rod may be secured directly to the screw but is preferable provided with a collar that is captured by an enlarged screw head to seat, orient and retain the threaded rod in position. A locking arm and retaining nut are provided over the threaded rod for affixing a spinal rod to the pedicle screw substantially over and aligned with the longitudinal axis of the screw. A yoke may be provided in the collar also to receive and secure the rod. An alternate cap and clamping elements enable the incorporation of cross links between multiple screws and/or rods.
