- This invention relates to orthopedic surgery and, in particular, constrained spinal implants for replacement of ruptured or excised spinal disks.
- Several attempts have been made to design a spinal prosthesis for replacement of missing or excised disk material that replicates the functions of the missing tissue. U.S. Pat. No. 4,759,769 to Hedman et al discloses an artificial disk device in which two plates are attached to the adjacent vertebrae by bone screws inserted through flanges on the plates. A spring biasing mechanism is captured between the plates to simulate the actions of the natural disk material. U.S. Pat. No. 5,246,458 to Graham and U.S. Pat. No. 6,228,118 to Gordon disclose other intervertebral implants with spherical flanges used to connect the device to adjacent vertebra. Graham also teaches a resilient structure.
- The patents to Marnay, U.S. Pat. No. 5,314,477, Buttner-Janz et al, U.S. Pat. No. 5,401,269, Yuan et al, U.S. Pat. No. 5,676,701, and Shelokov, U.S. Pat. No. 6,039,763, all are directed to the design of the opposing faces of the adjacent plates of an implant to provide a limited universal joint to simulate the natural movement of the spine.
- U.S. Pat. No. 5,683,465 to Shinn et al teaches two plates with bow shaped skirts which are interlocked.
- The invention is directed to a constrained spinal implant for insertion between adjacent vertebrae to function as a disk prosthesis. The prosthesis is formed from two plates fastened to adjacent vertebrae facing each other. The facing sides of the plates have an interacting, depending skirt. The skirts are range limiting wherein the skirt on a superior endplate can be shaped to limit lateral, flexion and extension motion.
- A depression is centrally located between the arcs of both plates. A sphere or ball is placed in the central depression of one of the plates. The plates are oriented to each other at 90 degrees and the ball is engaged in the depression of the other plate. The plates are then rotated about 90 degrees and the skirt of one plate interlocks with an opposed arcs of the other plate to prevent separation in the axial direction.
- Therefore, it is an objective of this invention to provide a constrained spinal implant for axial support of the spinal column which replicates the dimensions and function of an intervertebral disk.

spinal implant 10, shown inFIG. 1 , has an upper plate 11, alower plate 12 pivotable on a universally rotatable sphere orball 50. The upper plate 11 and thelower plate 12 form a cage when assembled with theball 50 captured for universal movement within the interior of the cage to define an inner ball andsocket 86. Of course, the position of the plates can be reversed, in use. Both upper plate 11 andlower plate 12 have a plan form substantially the size and shape of the end wall of the vertebra between which the implant will be placed to produce the maximum area of contact between the implant and the vertebra for stability and support. Obviously, different sized plates are necessary because of the difference in size of vertebra within regions of the spinal column and the different sizes or ages of patients. The concentric spinal disc can be sized as a cervical disc, a thoracic disc, or a lumbar disc. - The upper plate 11 has a
planar surface 14 for contact with the end wall of a vertebra and anopposite disk surface 15. Depending from the disk surface is acontinuous skirt 16 with opposed internal spherical bearing surfaces 17 and 18. The spherical bearing surfaces are approximately 180 degrees apart at their centers and extend about 90 degrees around the continuous skirt. However, it should be noted that smaller or larger spherical bearing surfaces spaced to provide axial guidance and load bearing may be utilized without departing from the scope of the invention. In the preferred embodiment, the diameter of the arcs is less than the periphery of the plate 11 leaving ahorizontal flange 19. Centrally located within the spherical bearing surfaces formed within the continuous skirt is areceptacle 13. Asleeve 51 is inserted in thereceptacle 13 and telescopes in the plate 11. Thesleeve 51 has aspherical depression 52. - The
lower plate 12 has aplanar surface 20 for contact with the end wall of a vertebra and anopposite disk surface 21. Upstanding from the disk surface is ancontinuous skirt 22 with opposed external spherical bearing surfaces 23 and 24. The spherical bearing surfaces are approximately 180 degrees apart at their centers and extend about 90 degrees around the skirt. However, it should be noted that smaller or larger spherical bearing surfaces spaced to provide axial guidance and load bearing may be utilized without departing from the scope of the invention. The diameter of the arcs is less than the periphery of theplate 12 leaving ahorizontal flange 25. Centrally located within the semi-circular arcs is areceptacle 26. Asleeve 53 is inserted in the receptacle and reciprocates in theplate 12. Thesleeve 53 has adepression 54 that is rounded and shaped to closely mirror the contours of thedepression 52. Thedepressions ball 50, are of such dimensions construction to provide bearing surfaces suitable to support the weight of the spinal column. - As shown, though the relationship could be reversed, the opposed spherical bearing surfaces 17 and 18 of the depending
skirt 16 are concentric with the opposed spherical bearing surfaces 23 and 24 of the upstanding skirt and of larger diameter allowing rotation of the plates relative to each other with surface contact between the outer spherical bearing surface(s) of the upstanding skirt and the inner bearing surface(s) 29 of the depending skirt to define an outer ball andsocket 85. - The constrained spinal implant provides support and range of motion similar to the natural joint in that the
plates 11 and 12 may rotate axially limited by natural anatomical structures, such as tendons, ligaments and muscles. To simulate the compression of the natural disk during normal activities, such as walking, an alternative embodiment as shown inFIG. 11 may include a spring mechanism o-ring plates 11 and 12. The springs are resiliently compressible. - In the manufacturing step, the o-
ring 61 is inserted and covered by thesleeve 53. Aretainer ring 58 is placed between the upper circumference of thesleeve 53 and is preferably laser welded to the plate. Other suitable permanent attachment methods well known in the art may also be used without departing from the scope of the invention. Similarly, an o-ring 60 may be used in the upper plate 11 with thesleeve 51 inserted and held in position by aretainer ring 55, the retainer ring can then be laser welded to the plate or other permanent attachment methods may be used. By absorbing some of the longitudinal loads, the prosthesis lessens the stresses on the adjacent natural disks. Further, during placement of the prosthesis, the springs may be compressed to lessen the overall height of the prosthesis. - The spine may bend laterally and tilt medially in flexion/extension in a range comparable to the normal range of motion. The implant of the instant invention provides limitation of these movements through interaction of the depending skirt and the upstanding skirt. As shown in
FIGS. 9 a-9 d, the components of the implant are connected together by orienting the spherical bearing surfaces 17-18 and 23-24 at about 90 degrees relative to each other. This action allows the skirts to be vertically overlapped. In a pre-couple orientation, theball 50 is placed in theinferior endplate 12 and the superior endplate 11 is placed over the ball and then the plates 11 & 12 are rotated through 90 degrees relative to each other. This rotation aligns the depending opposed spherical bearing surface(s) with the upstanding opposed spherical bearing surface(s) and interlocks the plates in a movable joint that cannot be separated axially. Theinner surface 28 of thecontinuous skirt 16 slidably contacts theouter surface 29 of theskirt 22. The contacting bearing surfaces are spherical or bowed, from the plate at least to the height of the diameter of theball 50, forming another ball and socket joint with the bottom edge of the dependingarc 23 of a larger diameter than the top edge of theupstanding arc 17 by which the plates are interlocked. Of course, the remainder of the inner and outer surfaces of the skirts may be straight or tapered and spaced apart to allow for bending and tilting. As shown inFIG. 2 theinferior endplate 12 and the superior endplate 11 are interlocked andFIG. 3 depicting the lateral movement of the superior endplate 11 in a range of ±10°.FIG. 4 depicts the inferior endplate in a flexion of about 10° andFIG. 5 depicts the inferior endplate in an extension position of about 15°. These ranges are only to be considered as illustrative, the skirts can be ground to a particular geometry to meet a particular patient needs.FIG. 10 illustrates therange limiting surface 17 that can be contoured to limit the lateral, flexion and extension motion for the superior endplate 11. - In the preferred embodiment, fastening to the vertebra can be enhanced by the use of
spikes 34 attached or formed onflanges - Alternatively, or in conjunction with spikes, each of
flanges flanges - The components are made from materials that are suitable for implantation in the living body and have the requisite strength to perform the described functions without deformation, e.g., the opposed bearing surfaces of the depressions and ball may be made of metal or ceramic or a suitable combination thereof, respectively, the ceramic material is implant grade alumina ceramic or a silicon nitride or carbide and the metal may be a nitrogen alloyed chromium stainless steel or cobalt chrome alloy, or titanium, and alloys of each, coated metals, ceramics, ceramic coatings, and polymer coatings.
- The plates may be made entirely of cobalt chrome alloy or only the inserts. In the high wear areas, such as the depressions, coatings or inserts may be used to prevent galling and permit repair. In this modular concept, the end plates may be titanium, titanium alloy, or stainless steel among other materials as discussed above.
- The
prosthetic ball 50 is preferably made from an implant grade alumina ceramic or a silicon nitride or silicon carbide material. Theball 50 may be formed entirely of the ceramic material or a ceramic coating on another matrix. The alumina ceramic or silicon nitride or silicon carbide material can be manufactured by isostatic pressing or any other suitable method well known in the art. Theball 50 is then machined to shape and the surface polished to a mirror-like finish. The ceramic ball is completely corrosion resistant and is non-abrasive. The solid matrix eliminates the wear particles, such as those liberated from metal, other coated metals and polyethylene implants. Theball 50 has excellent thermal conductivity thereby reducing patient discomfort associated with exposure to cold weather. Further, the alumina ceramic or silicon nitride implant will react well with x-ray and MRI (magnetic resonance imaging) diagnostic procedures. - The kit contains plates with protrusions and skirts of varying lengths to allow selection of components for an implant with the axial dimension substantially the same as the thickness of the disk the implant will replace. The kit may also contain upper and lower plate components of varying sizes.
FIG. 12 illustrates theimplant 10 having taperedendplates 11 and 12 that can be used for ease of insertion. Further, the implant can be assembled by a surgeon in the operating room allowing for modular endplate selection to make-up for custom disc construct. Modular endplates would allow control over disc-space height and enable a better match of the kyphotic/lordotic endplate angles. - Referring now to
FIG. 13 , the use of the instant implant provides for a constrained construct when the plates are coupled together. In addition to coupling the plates together, the outer ball and socket construction prevents migration of the plates in relation to each other. The face of each endplate may include a radial surface positioned in relation to the ball bearing centerline. Insertion of the instant invention may be aided by adrive tool 80 having ahandle 82 and aimplant holder 84 formed from a rigid shank. Theimplant holder 84 allows for impacting forces to be on the endplate faces 19 and 25, thereby eliminating an impact on theouter skirt 16. In this manner, both endplates are manipulated as a single unit. In use, theimplant holder 84 is positioned along the first end and conforms to the superior endplate of a constrained spinal implant by use of a C-shaped end with anupper surface 21 and alower surface 23 sized to fit between the upper plate and lower plate of the spinal implant. The second end forming ahandle 82 with animpact tip 83. The spinal implant is positioned within thefirst end 84 with the handle available to align the spinal implant. The impact tip available for receipt of mallet impact to allow a forced placement of the implant between the vertebrae. - A number of embodiments of the present invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. Accordingly, it is to be understood that the invention is not to be limited by the specific illustrated embodiment but only by the scope of the appended claims.
