- an artificial intervertebral disc (“AID") assembly comprised of first and second anchor plates (each of which has a vertebrae contacting side) and at least one composite structure that is fixed to the first and second anchor plates.
- the composite structure may be comprised of a column including woven and/or non- woven fiber (s).
- the column may comprise polyester.
- the column may comprise DACRON.
- the column may be at least partially hollow (e.g., having one or more holes therein) and may be filled (fully or partially) with a compressible material, such as an elastomer.
- the elastomer may include a silicone, a urethane, a thermoplastic elastomer, an elastomer alloy; a polyurethane/polycarbonate alloy, and/or any combination thereof.
- the column filler (e.g., elastomer) may store energy and then return the stored energy back to the physiological system (because the column filler may allow physiological-like displacement, the column filler may (like a physiological system) dissipate some strain energy).
- the compressive properties of the artificial intervertebral disc may be tuned to largely match those found in a natural intervertebral disc by utilizing a generally parabolic function.
- Artificial Intervertebral Disc 100 includes First Anchor Plate 102A and Second Anchor Plate 102B (each Anchor Plate 102A, 102B may comprise, for example (which example is intended to be illustrative and not restrictive), any desired biologically acceptable metal).

- Step 2 Discectomy: Evacuate the affected disc space using standard surgical procedures (see Fig. 22B).
- Step 3.1 Distraction: Interbody distraction is achieved thru the use of the Blade-Style Distractor. Insert the blade end of the distractor into the interbody space, placing them as far posterior as possible (this technique will help achieve parallel spacing). Turn the ratcheting device until proper distraction has been achieved (see Fig. 22C).
- Step 3.2 Distraction: Once parallel distraction of the interbody space has been achieved, (Blade Style Distractor may remain in place) the Pin Style Distractor is used to allow for access to the interbody space.
- Select desired pin styles For Pin Style 1, insert pins into the anterior aspect of adjacent vertebral bodies. Once the pins are properly positioned, the canulated arms of the distractor can be positioned into place. The ratcheting device can then be actuated until proper distraction has been achieved. Remove the Blade Style Distractor. For Pin Style 2, place arms of the canulated distractor in place on adjacent vertebral bodies. Drive the hex top pins thru the canulated arms into the vertebral bodies. The ratcheting device can then be actuated until proper distraction has been achieved.

- the first Broach (see Fig. 22H) is inserted into the disc space creating the M/L clearance for proper implant fit.
- the second broach (Fig 221), which removes the material from the posterior aspect of the joint space.

- Implant Insertion Load the prosthetic device onto the holder by aligning pins on holder (see Fig. 22K) with holes on the implant (see Fig. 22L). Turn knob on holder to actuate the jaws until a snug fit has been achieved. Place the device into vertebral space using flouroscopy. Once satisfied with implant placement, turn knob on holder to release the jaws and pull instrument away from implant (see Figs. 22M and 22N).

- a column when a column is utilized without a column filler (e.g., in the form of an essentially homogeneous structure), such a column may be integrated into the AID assembly (e.g., in terms of attachment to the anchor plates, patient customization) in essentially the same manner as a composite structure discussed herein.
- the surgeon may (during the surgical procedure) make the requisite incisions or access the site where the unhealthy or damaged disc is to be removed. After removal of the unhealthy or damaged disc or the unhealthy or damaged portion(s) of the disc, the surgeon may cut grooves in the endplates of the vertebral bodies that were adjacent to the removed disc. The grooves that are cut may be sized and shaped to correspond to an interface on an elevated portion of the anchor plate(s).
- the surgical procedure may also involve removing healthy portion(s) of the patient's disc(s) to the extent required for implantation of the AID assembly.
- the compressibility of the implant of the present invention may prove helpful during the implanting procedure.
- the implant may be compressed to smaller proportions than its uncompressed height. The surgeon can then, prior to releasing the implant from its compressed height, adjust its position to insure that the elevated interface on the anchor plates and the grooves cut into the vertebral bodies are aligned with each other. After the surgeon has ensured this is the case, the implant may be released from its compressed state (e.g., so that the elevated interface enters the grooves)
- the grooves may be cut in the vertebral body with a matching undercut, such that the anchor plates may be inserted (e.g., from the side, front or back) in a dovetail configuration.
- This embodiment may allow for positive initial tensile attachment between the anchor plates and the endplates, without having to wait for bony ingrowth.
- one or more components may be constructed of Ti, cobalt chromium, surgical steel and/or any combination thereof.
- customization may be carried out using multiple, interchangeable components (e.g., interchangeable composite structures).
- the customization may be carried out using a family of standard parts.
- customization of the AID assembly may be done at the place of manufacture (e.g., by a technician at the factory) and/or at the place of implantation (e.g., by a surgeon at the hospital).
- the vertebra contacting side of the anchor members may include gripping, tissue ingrowth promoting and/or bone ingrowth promoting elements, such as, for example (which examples are intended to be illustrative and not restrictive), grooves, teeth, protrusions, depressions or any combination thereof.
- mounting tabs associated with the anchor members may interface with the vertebrae along a planar interface, a curved interface, or a combination thereof.
- the mounting tabs may include gripping, tissue ingrowth promoting and/or bone ingrowth promoting elements such as described above.
- the column filler (e.g., elastomer) within the column may be of sufficient hardness as to form a distinct "core" within the column (such that the core fills essentially the entire space within the column or the core fills less than the entire space within the column (e.g., having one or more voids above the core, below the core and/or around the core between the core and the column)).
- the column filler (e.g., elastomer) within the column may be of insufficient hardness as to form a distinct "core" within the column but may instead fill the column in a more or less "fluid” manner (such that the column filler fills essentially the entire space within the column or the column filler fills less than the entire space within the column (e.g., having one or more voids above the column filler, below the column filler and/or around the column filler between the core and the column). Further still, the column filler (e.g., elastomer) may be extruded/injected onto the column(s).
- the column filler (e.g., elastomer) may protrude out from the top, bottom and/or side(s) of the column.
- the protruding column filler (e.g., elastomer) may be used to aid in attachment of the composite structure to the anchor plate (e.g., the protruding elastomer may be attached directly or indirectly (via an intermediate element) to an anchor plate using any desired attachment mechanism).
- the column may comprise any desired fiber and/or fabric.
- the attachment of the column(s) and/or composite structure(s) to the anchor plates may be carried out using a press fit, a rotary swage, welding (e.g., spot or continuous), a number of discrete interference dings, a forced interference fit, a threaded fit, a punch mechanism at a seam between parts and/or any other desired method (as well, of course, as any combination thereof).
- the device may be shaped as desired, such as having a circular shape, an oval shape or a kidney shape, for example (this could be effected by providing a desired shape to any of the components (e.g., the anchor plates and/or the column(s) and/or the composite structure(s))).
- the composite structure(s) may essentially fill the space between the anchor plates or there may be empty space between the composite structure(s).
- the column filler, the material used to coat the column(s) and/or the material impregnated into the column(s) may be any desired compressible, elastic compressible, extrudable and/or fiowable material (or combination thereof).
- the load/deflection curves associated with the present invention may result from underlying data having applied thereto any desired type of curve fitting (e.g., polynomial curve fitting to the second or third power).
- all dimensions, engineering notes, specifications, etc. identified in the Figs are intended to be examples and not be restrictive.
- any desired number of crimps may fully and/or partially encircle the perimeter of the column.
- any steps may be carried out in any desired order (and certain steps may be omitted and/or other steps added).
