Definitions
- an intervertebral disc can be subject to damage, such as compression, deformation, displacement, or wear, and more generally degeneration associated with the mechanical stresses that are applied thereto and that lead to anatomical and functional destruction of the disc and of the vertebral segment. This damage to the disc alters its mechanical behavior and causes instability which can, in turn, give rise to a painful osteoarthritic reaction.
- This pain can sometimes be eliminated by spinal fusion in which two adjacent vertebral bodies are joined together after removing the intervening intervertebral disc.
- a prosthetic device is usually placed between the two adjacent vertebral bodies, in place of the removed disc, to fill the space left by the removed disc and to allow bone to grow between the two vertebral bodies.
- prostheses can include first and second plates for fixing to adjacent vertebral bodies and an articulating mechanism, such as a ball joint, interposed between the two plates.
- an articulating mechanism such as a ball joint
- the articulating mechanism of the prosthesis can be subject to high levels of friction, thus making it sensitive to wear.
- Other artificial discs include ceramic bearing surfaces positioned within titanium endplates. While the ceramic materials reduce wear, these implants are limited by small bearing surfaces.
- mounting stiff ceramic inserts into titanium endplates can generate high stresses in the ceramic material and cause disc failure. Thick titanium endplates can also interfere with post-operative imaging, an important diagnostic tool.
- the present invention provides a disc prosthesis that features superior wear properties.
- the disc prosthesis is formed entirely or predominately of ceramic material, thus optimizing post-operative imaging.
- the present invention provides an implantable prosthetic device for replacing spinal discs.
- the device includes first and second endplates each having an articulating contact surface and a bone facing surface. At least one of the first and second endplates is formed of a ceramic material.
- the contact surface of the first endplate has a shape complementary to the contact surface of the second end plate, such that when the endplates are in contact with each other, the contact surface of the first endplate can articulate with respect to the contact surface of the second endplate.
- At least one non-ceramic bone attachment element is formed on or mated with at least one of the bone facing surfaces, such that the bone attachment element covers less than a full area of the bone facing surface.
- the bone attachment element can include bone-penetrating teeth formed from a material selected from the group consisting of a metal, a plastic, and combinations thereof. When positioned within a vertebral column, the bone-penetrating teeth are effective to resist retropulsion.
- the bone attachment element includes bone penetrating teeth formed from a shape memory material. The teeth can be positioned substantially parallel to the bone facing surface before activation and orientated to penetrate bone after activation.
- the disc prosthesis device can further include a mating element for mating with an insertion tool.
- the device includes a male mating element adapted to mate with an insertion tool.
- the mating element is positioned on the bone attachment element and is adapted to mate with a male or female insertion tool.
- the first and second endplates are formed of a ceramic material and each have an articulating surface and an opposed bone contacting surface. The articulating surfaces are complementary to each other such that the first and second endplates can articulate while in contact with one another and are unconstrained in their relative movement by any portion of the prosthesis.

- the present invention provides a prosthesis that conserves vertebral function and provides wear resistant articulation surfaces.
- superior tribological wear properties are provided by forming at least a portion, and preferably all or substantially all, of the prosthesis from a ceramic material having sufficient strength to withstand in- vivo and insertion loading.
- Ceramic bearing surfaces provide excellent wear resistant properties that allow the device to articulate when positioned within a patient's spine such that at least some of the natural mobility between adjacent vertebral bodies is conserved. Ceramic materials are also compatible with post-operative imaging such that a surgeon can determine if the prosthesis is properly positioned and/or can asses the health of surrounding tissue and adjacent levels.
- FIG. 1 illustrates a perspective view of a portion of a vertebral column including vertebral bodies Ia, Ib, Ic, Id, and natural discs 2a and 2b.
- a damaged disc between vertebral bodies Ib and Ic has been resected and replaced with a prosthetic disc 10 that has been inserted in the space created between the adjacent vertebral bodies (Ib, Ic).
- ceramic bearing surfaces of prosthesis 10 allow vertebral bodies Ib, Ic to maintain at least some degree of mobility.
- disc 10 can include bone mating surfaces, coatings, and/or bone penetrating elements, which together or separately, facilitate bone in-growth and help to fix the prosthesis in position.
- disc 10 in one aspect, includes first and second endplates 24, 26 each having an articulating contact surface 20, 22 and a bone facing surface 16, 18 where at least one of the first and second endplates is formed of a ceramic material. In one aspect, both endplates are formed entirely or substantially from ceramic materials.
- the prosthetic disc is generally shaped and sized for positioning between adjacent vertebral bodies and contacting the vertebral bodies.
- disc 10 can have a somewhat rectangular or trapezoidal shape with an anterior surface 14 and a posterior surface 12, and a superior surface 16 and an inferior surface 18.
- the superior 16 and inferior 18 surfaces are bone facing surfaces while interior surfaces 20, 22 (FIG. 2C) are articulating surfaces.
- the sides of disc 10, including anterior surface 14 and posterior surface 12 can be shaped to match the anatomical configuration of the inter- vertebral space into which disc 10 is inserted.
- posterior surface 12 can have a width shorter than that of the anterior surface 14, causing the width to taper from the posterior to the anterior.
- the height of disc 10 is also adapted to be compatible with the anatomical structure of a vertebral column, and in particular, the height should be such that it provides the desired spacing between adjacent vertebrae.
- Disc 10 in one aspect, is formed from a superior end plate 24 and an inferior endplate 26, each having ' a bone facing surface 16, 18 and an articulating contact surface 20, 22 that allow the endplates to move relative to one another.
- FIG. 2C shows an exploded view of disc 10 with articulating surface 22 of inferior endplate 26 adapted to articulate with articulating surface 20 of superior endplate 24.

- the shape of articulating surfaces 20, 22 allows for flexion, extension, lateral bending, and/or rotational movement.
- One skilled in the art will appreciate that a variety of alternative articulating surface shapes that allow relative movement of the endplates can be used.
- articulation of endplates 24, 26 could be provided by a three-piece (or more) design.
- a motile core could be positioned between endplates 24, 26.
- Other exemplary designs could include a ball-in-trough configuration.
- endplates 24, 26 are configured such that relative movement is not limited or constrained by the structure of prosthetic disc 10. As the endplates move relative to one another they do not encounter another portion of disc 10 that limits the amount of flexion, extension, lateral bending, or rotational movement of the endplates.
- Endplates 24, 26 can further include features for mating with an inserter tool (not shown).
- a mating element 30 can extend from anterior surface 14 of at least one the endplates and be adapted for gripping by an inserter tool.
- mating element 30, in one aspect includes a male tab, having substantially flat upper and lower surfaces, that extends from the surface of each endplate 24, 26.
- an inserter tool could mate with a female mating element 30, including for example, a recess in the anterior surface 14 of disc 10.
- mating element 30 could be positioned on a side surface of prosthetic disc 10.
- one or both of side surfaces 32, 34 of prosthetic disc 10 could include a slot within which an inserter tool could be seated.

- an insertion tool can instead have a shape corresponding to the anterior end of disc 10 and include features for gripping surfaces 16, 18.
- FIG. 3 illustrates one embodiment of prosthetic disc 10 that includes area 35 on bone facing surfaces 16, 18 that can be engaged by an inserter tool.
- inserter tools can be adapted to mate with disc 10.
- the superior and inferior surfaces 16, 18 of prosthetic disc 10 are positioned to face the adjacent vertebral bodies between which they will be inserted.
- these surfaces face the exposed bone of the adjacent vertebral bodies.
- these bone facing surfaces 16, 18 are bone contacting surfaces and are adapted to mate with bone. Once inserted within the vertebral column, the surfaces 16, 18 contact the adjacent vertebral bodies and, over time, the disc is secured through osteointegration as bone grows into the ceramic material that forms the disc.
- Surfaces 16, 18 can also include features, such as porous regions and/or recesses to enhance and facilitate bone in-growth.
- porous regions on the bone facing surfaces are provided by a coating 36 that fosters bone growth and/or bone adhesion.
- coating 36 shown in FIG. 3, could be positioned on surfaces 16, 18 to provide a rough and/or porous structure into which bone can grow.

- a non-ceramic bone attachment element 38, 38', 38", 38'", 38”” is positioned on one or both of the bone facing surfaces 16, 18. While ceramic materials are very hard and have low wear characteristics, forming bone penetrating members (e.g., spikes or teeth) from ceramic can be difficult because ceramic is brittle. To avoid this problem, bone attachment elements 38, 38', 38", 38'", 38"” can provide bone penetrating spikes or teeth 40, 40', 40” formed of a non-ceramic material. The spikes or teeth 40, 40', 40" penetrate and/or engage bone to prevent disc 10 from moving out of position once implanted. In addition, non-ceramic bone attachment elements can help to evenly distribute forces across the bone facing surfaces of the endplates.
- bone penetrating members e.g., spikes or teeth
- Bone attachment element 38, 38', 38", 38'", 38”” can be formed from a variety of non-ceramic materials such as metals and plastics.

- bone attachment elements 38 comprise two parallel strips of material with raised portions defining teeth 40.
- the bone attachment elements can be positioned, for example, with their axes /,-/ / and l 2 -h oriented in the anterior/posterior direction. While two bone attachment elements are positioned on each surface 16, 18 in FIGS. 4A through 5B, one skilled in the art will appreciate that disc 10 can include more than one bone attachment element per surface (e.g., three or more) or fewer (e.g., one).
- FIGS. 6A through 14 illustrate a variety of other exemplary configurations of the bone attachment elements.
- the bone attachment element could be positioned around the perimeter of the bone facing surfaces (FIGS. 6A and 6B), across the entire surface of the bone facing surfaces (FIGS. 7A and 7B), in a cross configuration (FIGS.
- attachment elements 38, 38', 38", 38'", 38"" can cover less than the full area of bone facing surfaces 16, 18. A portion of the ceramic bone facing surfaces 16, 18 thus remain uncovered by bone attachment element 38, 38', 38", 38'",
- FIGS. 5A through 6B and 8A through 14 illustrate disc 10 with at least a portion of bone facing surfaces 16, 18 uncovered by the bone attachment elements.
- the small profile of the bone attachment elements can facilitate post-operative imaging.
- covering only a portion of bone facing surfaces 16, 18 with the bone attachment element can minimize interference with post-operative imaging.
- Bone attachment element 38, 38', 38", 38'", 38”” can be fixed to prosthetic device 10 in a variety of ways, including, for example, brazing, adhesion, mechanical attachment, and combinations thereof. Endplates 24 and 26 can also include features, such as a recess to assist with attachment of the bone attachment element.
- bone attachment element 38' is mated with disc prosthesis 10 by way of a mechanical interlock, such as, for example snap-fit, friction fit, tongue-and-groove, overmolding, overcasting, thermal interference fit, and combination thereof.
- the bone attachment element can mate or interlock with recesses 42 on the anterior and posterior surfaces 14, 12 of disc 10.
- the ends of bone attachment element 38' can be flexible and include a protrusion that snaps into recess 42.
- bone attachment element 38" is seated within a recess in the bone facing surfaces (16, 18).
- the bone attachment element could be flush with the bone facing surfaces 16, 18, such that surfaces 16, 18 are easily accessed by bone.
- FIGS. 9A through 1OB also illustrate embodiments in which bone attachment element 38" is seated with a recess in the surfaces 16, 18 of the disc prosthesis.

- Teeth 40 positioned on bone attachment element 38, 38', 38", 38'", 38"", can be positioned at an angle with respect to the bone facing surfaces 16, 18 of disc 10, such that the teeth are driven into bone by retropulsive forces acting on the disc.
- the angle of teeth 40 with respect to the bone facing surface of the endplate can be in the range of about 5° and 75°, and preferably in the range of about 30° and 70°.
- teeth 40 are formed from a ridged material and are fixedly positioned.
- Teeth 40 can alternatively be flexible to facilitate insertion such that they are pushed down (i.e., retracted or flattened) during insertion. Once the disc is inserted, the teeth will press against the bone to resist retropulsion.
- teeth 40 can have a size, shape, and orientation that will be effective to resist removal or migration of disc 10.
- the teeth are unidirectional and are inclined in the posterior-anterior direction.
- Teeth 40 will not grab bone as disc 10 is inserted, but will resist retropulsion once the disc is inserted.
- the teeth can be positioned at an angle with respect to the direction of insertion.
- teeth 40 can be angled with respect to the axis L-L shown in FIG. 5A. This orientation helps to prevent lateral movement of the prosthetic disc.

- Disc 10 can be inserted with teeth 40" in their non-bone engaging position to facilitate insertion by reducing interference between teeth 40" and bone.
- bone attachment element 38"" is activated by an activating force, such as body heat and/or a supplemental heat source, and teeth 40" become oriented in a bone engaging position as shown in FIG. 14A.
- Bone attachment element 38"" can be formed from the variety of shape memory materials.
- Exemplary materials include, for example, nickel-titanium intermetallic compounds (e.g., Nitinol) that exhibit thermal shape memory.
- Preferred materials include those that are activated at a temperature above room temperature, such as at, or slightly below, body temperature.
- spike profiles are cut into a sheet of Nitinol and the sheet is heat treated so that the spikes will deploy (i.e., assume a bone penetrating position) at body temperature.
- Spikes 40" can lie substantially in the same plane as bone attachment elements 38"" during implantations, then deploy into a raised, bone penetrating position once the disc is inserted.
- the bone attachment elements can be in the form of bone engaging hooks (not shown), which can also be formed from a shape memory material.
- the bone engaging elements can include wires when in the non-activated, non-bone penetrating condition. In the activated condition, for example, the wires may lie substantially in the same plane as surfaces 16, 18. Upon activation by an activating force, the wires are transformed into hooks that penetrate and/or securely engage bone.

Cauthen | An articulating spinal implant for intervertebral disc replacement. The articulating spinal implant is formed from two elements, each engaging one of an adjacent pair of vertebra. An articulating mechanism between the two elements resists compression and lateral movement between the vertebra, but allows the adjacent vertebra to articulate about an instantaneous axis of rotation. | |
