Abstract

The present invention teaches an improved spinal fusion implant and method of implanting same. The implant includes a shell and an insert, the insert capable of situating first and second plates of the shell with respect to each other and of preventing unwanted loosening of fasteners placed through the shell and into the adjacent vertebral bodies. The method includes implanting a shell, selecting an insert from a plurality of inserts, and placing an insert between first and second plates of the shell.

Description

    BACKGROUND OF THE INVENTION
  • [0001]
    The present invention is directed to spinal implants, and more particularly, spinal fusion implants.
  • [0002]
    The deterioration of vertebral bodies and/or vertebral discs is a major cause of back and neck pain in many patients. Through the years, many different techniques for restoring the natural anatomical spacing in the spine and thereby alleviating this pain have been developed and practiced by surgeons. For instance, implants and techniques for implanting such implants have been designed to preserve motion between adjacent vertebral bodies. These motion preserving implants are adapted to emulate a removed spinal disc. Examples of such implants (and the methods of implanting same) are disclosed in U.S. Pat. Nos. 6,989,032 (“the '032 patent”) and 7,169,182 (“the '182 patent”), the disclosures of which are hereby incorporated by reference herein. Nonetheless, even given the success of such motion preserving devices, it is still sometimes necessary to fuse adjacent vertebral bodies so that no movement is permitted therebetween.
  • [0003]
    Spinal fusion surgery typically involves removing the disc material from between adjacent vertebral bodies, which thereby creates an empty intervertebral space. In this space is implanted an implant or cage that is then fixably mounted to the end plates of the adjacent vertebral bodies. Bone growth is often permitted through the implant, and is in fact sometimes provoked by the placement of bone growth inducing substances within the cage. However, even given this bone growth through the cage, it is sometimes necessary to at least initially mount the cage to the vertebral bodies through the use of fixation elements such as screws. Furthermore, it has also determined that providing an angled implant or cage can aid in returning the adjacent vertebral bodies to their natural “lordotic” angle.
  • [0004]
    Even if a surgeon initially determines that he or she wishes to perform a motion preserving surgery on a patient, sometimes it becomes apparent during the procedure that a fusion procedure would benefit the patient. Likewise, surgeons often recognize the need to fuse vertebral bodies at levels adjacent to the initial one in question. Thus, it is desirable to have a fusion implant that can easily be implemented and implanted utilizing the tools and procedure used in a motion preserving surgery. Moreover, it is also desired to have such a fusion implant be easily implanted using those tools, easily affixed to the intervertebral bodies, and prevented from becoming dislodged even after just initially being implanted.
  • [0005]
    Therefore, there exists a need for an improved spinal fusion device.
  • SUMMARY OF THE INVENTION
  • [0006]
    A first aspect of the present invention is a spinal implant for fusing together first and second vertebral bodies. In accordance with one embodiment of this first aspect, the implant includes a first member having a first surface for engaging the first vertebral body, a second surface, and a first opening extending between the first and second surfaces. The implant also includes a second member having a third surface for engaging the second vertebral body, a fourth surface, and a second opening extending between the third and fourth surfaces. A living hinge connecting the first and second members is also included and preferably allows for movement of the first and second members with respect to one another. Finally, an insert is disposed between the first and second members, the insert covering the first and second openings about the second and fourth surfaces.

  • DETAILED DESCRIPTION
  • [0032]
    Referring to the drawings, wherein like reference numerals refer to like elements, FIGS. 1-6 depict a first embodiment intervertebral fusion device or spinal implant for fusing together first and second vertebral bodies, designated generally by reference numeral 10. As is shown in the drawings, implant 10 includes a shell 12 and an insert 14. Moreover, implant 10 is also provided with a plurality of fasteners (shown in the drawings as screws 16 a-d) for placement through portions of the shell and into adjacent vertebral bodies. However, one of ordinary skill in the art would readily recognize that other types of fasteners could be utilized, e.g., pins or the like. The specifics of each of the components of implant 10, as well as their operation and use will be discussed more fully below.
  • [0033]
    As is shown in FIGS. 1-6 and even more specifically shown in FIGS. 7-9, shell 12 includes a first plate or member 18, a second plate or member 20, and a pair of resilient or living hinge members 22 a and 22 b. First member 18 includes a first surface 24 for engaging an upper vertebral body, a second surface 26 for engagement with insert 14, a plurality of bone growth apertures collectively referred to by reference numeral 28, and two fastener holes 30 and 32. First surface 18 is formed with a plurality of vertebral body engaging members, including teeth 34 and surfaces 36. Second surface 26 is formed with countersunk surfaces 38 and 40 in the vicinity of fastener holes 30 and 32, respectively, and a projection 42 extending toward second member 20. Similarly, second member 20 includes a third surface 44 for engagement with the lower vertebral body, a fourth surface 46 for engagement with insert 14, a plurality of bone growth apertures collectively referred to with reference numeral 48, and two fastener holes 50 and 52. Also in a similar fashion to first member 18, third surface 44 is formed with vertebral engaging elements including teeth 54 and surfaces 56, while second surface 46 includes countersinks 58 and 60 in the vicinity of fastener holes 50 and 52, respectively, and projection 62 extending toward first 18. Moreover, as is best shown in FIG. 8, extending from second surface 26 of first member 18 are extensions 64 and 66, and extending from fourth surface 46 of second member 20 are extensions 68 and 70. These extensions create a substantially rectangular space 72 for reception of insert 14, as will be discussed more fully below. First plate 18 may also include apertures 74 and second plate 20 may include apertures 76, which are utilized in engaging an insertion tool.
  • [0034]
    Resilient members 22 a and 22 b are shown as living hinges. Essentially, these elements are curved elements being made of a material capable of bending upon an application of force to one of or both of first and second members 18 and 20. For example, upon placement of differently sized inserts 14 between the first and second members, hinges 22 a and 22 b are capable of allowing for the expansion or the contraction of the device. While shown in the drawings as being composed of the same material as first and second members 18 and 20, it is noted that members 22 a and 22 b can be constructed of different materials. Likewise, the overall shape of members 22 a and 22 b can vary from the rounded structures shown in the drawings.
  • [0035]
    In the embodiment shown in the drawings, shell 12 is formed of titanium, but it is noted that other materials such as stainless steel, polymer, or the like can be utilized. It is also noted that the specific configuration of shell 12 may widely vary in different embodiments of the present invention. For example, the overall shape of the shell which is shown as being similar in nature to the implants shown and described in the '032 and '182 patents, but may vary depending upon the different portion of the spine in which it is to be implanted or the design of an implant of which it is to emulate. The vertebral engaging surfaces may also vary, including the specific vertebral engaging members disposed thereon. Furthermore, the apertures extending through the first and second members may vary, including the overall amount of bone growth apertures and screw holes. While fastener holes 30, 32, 50, and 52 are shown as being angled, other angles and/or perpendicular configurations are contemplated. Likewise, the configuration of projections 42 and 62 may also vary as can the space 72 for accepting insert 14.
  • [0036]
    Turning now to the configuration of insert 14, it is noted that such is preferably of a unitary construction. However, in other embodiments, different configurations are contemplated. With specific reference to FIGS. 10-14, insert 14 includes a main body 80 having a front face 82, a rear face 84, a top surface 86, a bottom surface 88, a left side surface 90, and a right side surface 92. Extending from the left and right are flanges 94 and 96, such that they form a continuous surface with front face 82, flange 94 includes a rear face 95, and flange 96 includes a rear face 97. In addition, as is shown in the drawings, formed through top surface and bottom surface is an aperture 98, which generally cooperates with apertures 28 and 48 of first and second members 18 and 20, respectively, in order to provide for a bone growth channel between adjacent vertebral bodies. Finally, front face includes an aperture 100, which is shown as being threaded for engagement with an insertion tool (not shown).
  • [0037]
    It is to be understood that insert 14 may widely vary from that which is shown in the drawings. For one, insert 14 may vary to properly cooperate with variations of shell 12. Certain portions of insert 14 may also vary and still be capable of cooperating with shell 12 as shown. For instance, flanges 94 and 96 may simply be extensions of front face 82 (i.e., rectangular) rather than the rounded structures that are illustrated in the drawings. Moreover, aperture 100 may be configured differently to engage an insertion tool (not shown). For instance, insert 14 may include an aperture 100 which is meant to cooperate with a spring detent or the like. Additionally, insert 14 may include a differently configured aperture 98 (or multiple apertures) for cooperation with like apertures formed in first and second members 18 and 20 of shell 12. Finally, insert 14 may be constructed of many different types of materials. For example, it is contemplated to form insert 14 of PEEK™ or of a biological material such as bone. In the case of the latter, the patient's own bone may be utilized to form insert 14 by any one of many known processes.
  • [0038]
    During a surgical procedure in which the above-discussed implant 10 is implanted, the surgeon first sees to the preparation of the intervertebral space between the adjacent vertebral bodies in order to be capable of receiving shell 12. This is shown in FIG. 15 and may include the removal of disc material and/or the preparation of the end plates of the vertebral bodies. Shell 12 is then inserted in the prepared space (see FIG. 16). In this regard, an insertion tool (not shown) may be engaged with apertures 74 and/or 76 of the first or second plates, or shell 12 may simply be placed by hand into the space. The above-discussed features of surfaces 24 and 44 (i.e., spikes 34 and surfaces 36) may aid in the retainment of shell 12 between the adjacent vertebral bodies. Once in place, fasteners (such as screws 16 a-16 d shown in FIGS. 1-6) may be placed through fastener holes 30, 32, 50, and 52 and into the adjacent vertebral bodies (see FIG. 17). Once again, it is noted that fastener holes 30, 32, 50, and 52 may be angled in any fashion to allow for specific placement of the fasteners through shell 12 and into the intervertebral bodies. It is noted that although the fasteners are shown in FIGS. 1-6 as screws having specific configurations, many different fastener configurations may be employed in fixing shell 12 to adjacent vertebral bodies, including differently configured screws.
  • [0039]
    With shell 12 in place, insert 14 may then be placed between first and second plates 18 and 20, preferably into above-discussed space 72. Insert 14 partially inserted into shell 12 is shown in FIG. 18. In placing insert 14, a tool (not shown) may be engaged with the threading of aperture 100, or, in the case of a differently configured aperture, another type of connection. Prior to engaging the insert with the tool, a surgeon may select one insert 14 from a plurality of differently sized and/or shaped inserts. These different inserts ultimately affects the disposition of plates 18 and 20 of shell 12. For example, a larger sized insert would increase the distance between plates 18 and 20, while differently shaped inserts may affect the amount of angle between the plates. Thus, depending upon the spacing or lordotic angle desired between adjacent vertebral bodies, different inserts having different sizes and/or differently angled upper and lower surfaces may be selected.
  • [0040]
    Once the surgeon makes the proper determination of the insert to utilize, it is coupled with a tool (not shown) or placed by hand between plates 18 and 20 (see FIG. 18). This placement of the insert preferably moves plates 18 and 20, and thusly the adjacent vertebral bodies to the position desired. Living hinges 22 a and 22 b allow for this movement while at the same time forcing plates 18 and 20 toward insert 14. At a certain point, front face of insert 14 is pushed past projections 42 and 62 so that the insert is forcibly maintained within space 72 of shell 12 (see FIG. 19). In this regard, it is noted that projections 42 and 62 are designed as ramps, which preferably allow for the easy insertion of insert 14 within space 72. However, once front face of insert 14 passes projections 42 and 62, the insert is thereby retained within the space. It is noted that other configurations for projections 42 and 62 may be employed. Once in this position, flanges 94 and 96 of insert 14 are disposed at least partially over a portion of the fasteners placed within fastener holes 30, 32, 50, and 52. In the preferred embodiment shown in the drawings, flanges 94 and 96 are placed over the heads of screws 16 a-16 d (best shown in FIG. 2). This final position for insert 14 and its projections preferably prevents the loosening or backout of the screws that may occur. In other words, flanges 94 and 96 prevent the screws from coming out of the vertebral bodies.
  • [0041]
    As is mentioned above, insert 14 may be made of various materials. For example, the insert may be constructed at least partially of metal, polymer, and/or bone material. In the latter case, insert 14 may encourage growth of bone through aperture 28, aperture 98, and aperture 48 to thereby fuse the adjacent vertebral bodies. Furthermore, it is contemplated that bone growth including substances may be placed within these apertures (or one of the apertures) in order to even further facilitate or, in the case of inserts constructed of nonbone material, promote such growth. It is contemplated that other embodiments of shell 12 and insert 14 may include additional apertures which promote further grown from adjacent vertebral bodies therethrough.
  • [0042]
    Although the invention herein has been described with reference to particular embodiments, it is to be understood that these embodiments are merely illustrative of the principles and applications of the present invention. It is therefore to be understood that numerous modifications may be made to the illustrative embodiments and that other arrangements may be devised without departing from the spirit and scope of the present invention as defined by the appended claims.
