Abstract
A spinal fixation assembly includes a fusion cage to which a plate is mated. The plate is configured to receive, retain and orient bone screws.
Description
- This application is a continuation of U.S. patent application Ser. No. 09/449,105, filed on Nov. 24, 1999, entitled “Anterior Lumbar Interbody Fusion Cage With Locking Plate,” which is expressly incorporated herein by reference.
- The present invention relates to medical devices, and more particularly to an implantable structure for promoting fusion of adjacent vertebral bodies.
- Advancing age, as well as injury, can lead to changes in the bones, disks, joints, and ligaments of the spine producing pain from nerve root compression. Under certain circumstances, alleviation of pain can be provided by performing a spinal fusion. This is a procedure that involves joining two or more adjacent vertebrae so that they no longer are able to move relative to each other.
- Many prosthetic devices are known for promoting fusion of the spinal vertebrae, and the devices can be classified, in part, based upon the approach to the spine that will be taken by the surgeon (anterior, posterior, lateral, etc.). None of the known devices is completely satisfactory, and improvements are desirable.
- The present invention improves upon known spinal fusion devices, especially those devices intended for an anterior approach to the spine. In an exemplary embodiment, a spinal fixation assembly includes a fusion cage to which a plate is mated. The plate is configured to receive, retain and orient bone screws, thereby holding the fusion cage and adjacent vertebral bodies in a stable relationship to promote fusion.
- Additional features of the assembly can include a plate mated to the fusion cage so as to be slidable therewith, and joining them with a mortise and a tenon. The plate can include extensions or tabs through which bone screws are passed and retained on one or both of the superior and inferior sides of the fusion cage. The tabs can be angled to orient the screws as desired.
- The fusion cage can include convex superior and inferior surfaces, and it can be tapered from the anterior face to the posterior face. Both the fusion cage and the plate can include insertion tool guide and engagement features, such as bores and notches. Fins can be provided at one or more points on the inferior and superior faces of the fusion cage.
- The invention will be more fully understood from the following detailed description taken in conjunction with the accompanying drawings, in which:
- FIG. 1 is a plan view of a fusion cage in accordance with the present invention;
- FIG. 2 is a view of the anterior face of the fusion cage of FIG. 1;
- FIG. 3 is a side view of the fusion cage of FIG. 1 with bone screws;
- FIG. 4 is a plan view of an embodiment of a fusion cage in accordance with the invention having fins on the superior face of the cage;
- FIG. 5 is a view of the anterior face of the fusion cage of FIG. 4;
- FIG. 6 is a side view of the fusion cage of FIG. 4;
- FIG. 7 illustrates adjacent vertebral bodies being separated in preparation for insertion of a fusion cage;
- FIG. 8 depicts a portion of the spine following placement of the fusion cage of FIG. 1;
- FIG. 9 depicts a portion of the spine following placement of the fusion cage of FIG. 4;
- FIG. 10 is a side elevation view of a bone engagement fin in accordance with the invention; and
- FIG. 11 is a top view of an exemplary bone engagement fin.
- FIG. 1 is a plan view of a fusion cage in accordance with the present invention. The cage includes a
body 10 that approximates the shape and size of the annulus portion of a disk which normally separates two vertebral bodies. Thebody 10 includes faces that are named in relation to their orientation with respect to a patient. Specifically, thebody 10 includes ananterior face 12, aposterior face 14, asuperior face 16, and an inferior face 18 (visible in FIG. 2). Except where specifically noted, as used herein, “face” is not intended to connote the outwardmost surface (“face surface” is used) or a specific geometry (e.g., planar). Rather, “face” refers to a general region on different sides of thebody 10. A carbon fiber composite or other radiolucent material is well suited for fabrication of the body. - The cage further includes a
plate 20 that is matable with thebody 10. Titanium or carbon fiber composites are suitable materials for theplate 20. As shown in FIGS. 1, 2, and 3, theplate 20 is mated with theanterior face 12 of thebody 10 for an anterior approach to the spine. However, other embodiments of the fusion cage are configured for mating theplate 20 to thebody 10 at locations other than theanterior face 12 as required for an anterolateral or lateral approach to the spine. - Although the
plate 20 can be bonded firmly to thebody 10 so that the plate and body cannot move with respect to each other, they can also be mated to allow movement with respect to each other. For example, in the illustrated embodiment, theplate 20 includes atenon 24 that is disposed within amortise 26 defined by thebody 10, wherein the tenon can slide in a superior/inferior direction within the mortise. - Continuing to refer to FIG. 1, the fusion cage can also be provided with first and second
transverse elements posterior face 14 to theanterior face 12. Thetransverse elements body 10 and provide additional load bearing surface. Thetransverse elements depression 34 in one or both of thesuperior face 16 orinferior face 18 of the body or defined by theplate 20 as shown in FIG. 2. In an exemplary embodiment, the guide path is about 8 mm wide and recessed about 1 mm to 2 mm below the superior/inferior face surface. - Referring now to FIG. 2, an embodiment of the
plate 20 is shown mated to theanterior face 12. In this illustration, fourbone screw holes hole 44. Theguide hole 44 is aligned with a bore 46 (shown in FIG. 1) in thebody 10. Both theguide hole 44 and thebore 46 are configured to receive a portion of an insertion tool (not shown), and both the guide hole and bore can be provided with tool engagement features such as threads. As shown, thebone screw holes tabs 36′, 38′, 40′ and 42′, wherein the tabs and the remainder of theplate 20 can all lie in the same plane, or one or more of the tabs can be angled with respect to the remainder of the plate or one or more of the other tabs. - Turning to FIG. 3,
bone screws tabs 40′ and 38′, respectively, such that the head of each screw engages the respective tab to inhibit passage of the head through the aperture in the tab. In an exemplary embodiment, the screws are about 3.6 mm in diameter and about 22 mm in length. The screws are of the “locking” type, so that they cannot “back out” of the holes in the plate. - Continuing to refer to FIG. 3,
tabs 38′ and 40′ are shown angled with respect to the remainder of theplate 20 so thatscrews body 10. The angle formed by the tab(s) and plate, as well as by the screw(s) and medial plane, is designated as “α” and is determined by a particular situation and a patient's anatomy. Although the angle “α” can range from 15° to 60°, for most applications the angle “α” is about 20°. However, in other embodiments, the tabs are flexible or readily bent with respect to the remainder of theplate 20. - Also shown in FIG. 3 are other advantageous features of the fusion cage, such as flat to slightly convex inferior and superior face surfaces18 and 16, respectively, and a slightly tapered (about 10°) or wedge profile, wherein the
body 10 is thicker at theanterior face 12 than at theposterior face 14. - Referring now to FIG. 4, a fusion cage is shown with
sharp fins 50 on the superior face of thetransverse elements fins 50 can also be provided on the inferior face of thetransverse elements exemplary fin 50 has afirst end 68 and asecond end 70, and as illustrated in FIG. 4, each fin is oriented in a generally anterior/posterior so that the first end is closer to theposterior face 14 of the fusion cage and the second end is closer to theanterior face 12. One or more fins can be tapered so that thesecond end 70 is taller than thefirst end 68 which merges flush with the face of the cage on which it is formed or mounted. Also, as shown in FIGS. 4 and 11, thesecond end 70 can be wider than thefirst end 68 which comes to a point. - Continuing to refer to FIG. 10, a
posterior face 72 can be angled during manufacture to provide a range of fin configurations. When an angle defined by theposterior face 72 and aline 74 formed by the intersection of opposing fin sides 76 and 78 is small (e.g., α1) atop fin portion 80 forms a “spike” that readily will dig into bone if the fin is moved toward thesecond end 70. If, as shown by dotted lines in FIG. 10, and from above in FIG. 11, the angle defined by theposterior face 72 and aline 74 formed by the intersection of opposing fin sides 76 and 78 is larger (e.g., α2) atop fin portion 80 forms a “spike” that readily will dig into bone when the fin and bone are pressed toward each, as when the fusion cage is compressed between two vertebral bodies. - The fusion cage of FIGS. 4, 5 and6 does not include a
plate 20, but it does include abore 46 for engaging an insertion tool, as well as a guide path or groove. Additional advantages of the present invention are evident when the invention is viewed in context. - FIG. 7 is a lateral view of adjacent
vertebral bodies - FIG. 8 depicts the fusion cage described above with respect to FIGS. 1, 2 and3 after it has been implanted. In this view, portions of the vertebral bodies are shown cut-away to illustrate the penetration of the bone screws 58 and 60 into the bodies. It is important to note that screw heads 62 and 64 are flush or sub-flush with the
anterior face surface 66 of the fusion cage, thus minimizing the likelihood that major blood vessels running along the spine will be injured. - FIG. 9 illustrates the fusion cage described above with respect to FIGS. 4, 5 and6 after it has been implanted. In this view, portions of the vertebral bodies are shown cut-away to illustrate the penetration of the
fins 50 into thevertebral bodies fins 50 can be tapered both in height and width. Thus, the tapering, in combination with the anterior/posterior orientation of the fins, allows the fusion cage to be inserted between the vertebral bodies with minimal resistance due to the fins, thereby minimizing necessary distraction distance between vertebral bodies. Also, the raised second end of the fins significantly inhibits anterior movement of the fusion cage once it has been positioned between vertebral bodies, as it “digs-in” to the vertebral bone if the fusion cage is urged in an anterior direction. In other words, the fins enhance purchas and provide expulsion protection. - Prior to inserting a fusion cage between vertebral bodies, the space bounded by the
body 10 andtransverse elements 28 and 30 (if included) can be filled with autograft or allograft bone, or demineralized bone matrix (DBM) to promote fusion. Over a period of about three months the vertebral bodies fuse. - As should be readily apparent from the preceding description, the present invention provides many advantages. For example, the fusion cage is sufficiently broad and thick so that only a single cage is needed to replace an excised disk. The profile and slightly bowed or convex superior and inferior surfaces of the fusion cage body closely approximate the shape of a natural disk and provide an excellent, stable, load-bearing surface. The plate, when included, ensures that the body will not become dislodged from the spine, yet is readily accessible with an anterior approach. Further, the plate allows bone screws to be deeply embedded into the vertebral bodies without piercing or otherwise damaging the hard, load-bearing, cortical bone. Also, both the plate and the body include features that allow for relatively easy manipulation and insertion with appropriately configured surgical tools.
- Of course, one skilled in the art will appreciate further features and advantages of the invention based on the above-described embodiments. Accordingly, the invention is not to be limited by what has been particularly shown and described, except as indicated by the appended claims. All publications and references cited herein are expressly incorporated herein by reference in their entirety.
