Abstract
A method of repairing a bone joint by using a simple and flexible artificial ligament which easily conforms to a patient's anatomy and can be used independently or in combination with an intervertebral graft, implant or prosthesis to return stability to the spine subsequent to a surgical spine procedure, is disclosed. The method includes anchoring the artificial ligament to at least two vertebrae to aid in restoring stability to the compromised joint. The artificial ligament is also disclosed.
Description
- This application is a divisional of U.S. patent application Ser. No. 09/543,288 filed Apr. 5, 2000 which claims the benefit of U.S. Provisional Patent Application No. 60/127,735, filed Apr. 5, 1999, the entire disclosure of which is hereby incorporated by reference.
- The present disclosure relates generally to prosthetic members for joining or repairing bone segments, including artificial ligaments and, more specifically, to an artificial ligament intended for partial or full replacement of the anterior longitudinal ligament of the anterior lumbar, thoracic or cervical spine.
- Ligaments extend between adjacent bone structures and serve a primary function of maintaining and providing appropriate stability to the bone structures to maintain the structures in aligned, spaced relation, particularly when subjected to loads in tension or upon torsional movement. Spinal ligaments stabilize and support vertebral bodies during movement of the spine.
- During surgical treatment of the spine, a section of a spinal ligament may be resected to provide access to a diseased or damaged intervertebral disc and/or to permit introduction of a fusion implant, bone graft or intervertebral disc prosthesis intended for long term support of the vertebral bodies. The bone graft, fusion implant or intervertebral disc return stability to the spinal column in compression and flexing, however, due to removal of the spinal ligament, the biomechanical characteristics of extension and torsional stability lost by the ligament's removal must be replaced. Current techniques involve the use of metal bone plates which are secured to the vertebral bodies with screw locking mechanisms. Conventional bone plates, however, are rigid and, thus, significantly inhibit spine mobility. Additionally, the screw locking mechanisms utilized with such plates are relatively complicated and provide minimal flexibility with respect to fastener positioning, etc.
- Accordingly, the present disclosure is directed to a simple and flexible artificial ligament which easily conforms to a patient's anatomy and can be used independently or in combination with an intervertebral graft, implant or prosthesis. In one preferred embodiment, an artificial spinal ligament is in the form of a flexible conformable plate dimensioned to span adjacent vertebrae and having openings for reception of bone screws, fasteners, etc. to mount the plate to the vertebrae. The biomechanical supporting characteristics of the plate approximate the characteristics of the ligament (e.g., anterior spinal) which it replaces thereby providing appropriate support to the spine in extension which also permitting normal spine mobility. A method of supporting adjacent vertebrae with the artificial ligament is also disclosed.
- Preferred embodiments of the disclosure are described herein with reference to the drawings wherein:
-
FIG. 1 is a perspective view of the artificial ligament of the present disclosure; -
FIG. 2 is a top plan view of the artificial ligament ofFIG. 1 ; -
FIG. 3 is a cross-sectional view taken along lines 3-3 ofFIG. 2 ; -
FIG. 4 is a perspective view of an alternate embodiment illustrating mounting thereof to the vertebral column; -
FIG. 5 is a top plan view of an alternate embodiment ofFIG. 1 ; -
FIG. 6 is a cross-sectional view taken along lines 6-6 ofFIG. 5 ; and -
FIG. 7 is a perspective view of another alternate embodiment of the artificial ligament. - Referring now to the drawings, in which like reference numerals identify similar or identical elements throughout the several views, there is illustrated the artificial ligament of the present disclosure. The artificial ligament of the present disclosure is intended to replace part or all of the supporting function of a ligament previously removed in connection with a surgical procedure. The artificial ligament has particular application in replacing the supportive function of a spinal ligament, e.g., anterior or posterior, which may have been fully or partially resected during a spinal procedure. The artificial ligament is advantageously dimensioned to be positioned to span adjacent vertebrae to restore the natural biomechanics, e.g., including tensional support and range of motion, of the removed ligament segment. The artificial ligament is contemplated for use with a bone graft, fusion implant or artificial disc to compliment the compressive load characteristics of the implant with its tensional supporting capabilities during healing. It is also envisioned that the ligament may be utilized in other capacities such as, for example, repair of other body ligaments such as the anterior crucial ligament, etc.
- Referring initially to
FIGS. 1-3 ,artificial ligament 100 includes ligament body orplate 102 which is advantageously dimensioned to span at least two adjacent vertebrae. It is envisioned that theligament body 102 may span three or more vertebral bodies. In a preferred embodiment, the length “1” ofligament body 102 ranges from about 1-3 inches, preferably about 2 inches. -
Ligament body 102 is preferably fabricated from a generally flexible material. The selected flexible material ofligament body 102 preferably has physical characteristics which approximate the biomechanical characteristics of the spinal ligament which it replaces. More specifically, the selected material ofligament body 102 supports the spine and provides stability'in extension, i.e., the ligament body has tensional load bearing capabilities while also permitting a degree of flexibility approximating the natural ligament. A preferred material of fabrication forligament body 102 includes a flexible polymeric material such as polyethylene. -
Ligament body 102 defines first and second webbody end portions 104 connected throughintermediate body portion 106′. Webbody end portions 104 each include a pair ofapertures 108 for reception ofbone fasteners 110. As best depicted inFIG. 2 ,apertures 108 may be generally elongated or slotted in the longitudinal direction with respect to longitudinal axis “a” ofbody 102 to permit multi-position capabilities of thebone fasteners 110 with respect toligament body 102 and the vertebral bodies as will be discussed.Apertures 108 are preferably countersunk defining a beveled or chamferedsurface 112 adjacent the upper surface of theligament body 102 for reception of thehead 114 of thebone fasteners 110 in flush relation therewith. Although twoapertures 108 are shown in eachweb end portion 104 of the preferred embodiment, it is envisioned that eachweb portion 104 may have more than two apertures or only one aperture. With particular reference toFIG. 2 ,intermediate body portion 106 has a width “w” which is substantially less than the corresponding width ofweb portion 104. Such dimensioning reduces the transverse profile ofligament body 102 thereby increasing flexibility to facilitate torsional movement ofligament body 102 upon corresponding movement of the patient's spine. The width “w” ofintermediate body portion 102 ranges from about 0.125 inches to about 0.375 inches, more preferably, about 0.250 inches. - With reference again to
FIG. 1 ,bone fasteners 110 serve as anchoring means for securing theligament body 102 to the adjacent vertebrae. Thepreferred bone fastener 110 includes afastener head 114 and afastener shaft 116 extending from the fastener head. Thefastener shaft 116 is threaded preferably with a self-tappingthread 118. Upon mounting ofbone fastener 110 within the adjacent vertebrae, thefastener head 114 is preferably flush with the upper surface of theligament body 102. Other anchoring means for mountingligament body 102 to the vertebral bodies are envisioned by one skilled in the art including expandable bolts, screws, non-threaded fasteners, etc. - In use in connection with an anterior spinal procedure, the anterior ligament is removed to permit access to a diseased or damaged disc section. A partial or full discectomy may be performed followed by insertion of a bone graft, fusion implant (e.g., as disclosed in U.S. Pat. No. 4,961,740, the contents of which are incorporated herein by reference) or an intervertebral prosthesis (such as disclosed in commonly assigned application Ser. No. 09/098,606, filed Jun. 17, 1998, the contents of which are incorporated herein by reference).
- When used with fusion devices, the
bone fasteners 110 are placed at theouter area 108 r of theopenings 108 so the ligament is rigid in tension while allowing for compression. This provides for immediate stability in extension as extension loads immediately place the ligament in tension. Thefasteners 110 are free to move withinopenings 108 relative to theligament 102 in compression. This also permits graft compression. - When used with artificial discs, the
fasteners 110 are placed in themiddle 108 m orinner part 108 i of theopenings 108 to permit limited relative motion offasteners 110 withinopenings 108 of the ligament in both flexion and extension. Extension ultimately leads to tension in the ligament as thefasteners 110 meet theends 108 r of theopenings 108. Thus, movement in tension and compression is provided. This flexibility also reduces the likelihood of thefasteners 110 backing out over time. -
FIG. 4 illustrates an alternate embodiment of the artificial ligament whereintermediate body portion 106 includes an elongatedlongitudinal depression 120 defining a reduced thickness ofligament body 102. This reduced thickness permits the surgeon to create anadditional opening 108 in theligament body 102 to receive abone fastener 110 for further fixation to the vertebrae. More specifically, during the surgical procedure the surgeon may create an opening at a desired location withinintermediate body portion 106 with a punch or the like. A multitude of openings (shown in phantom) may be formed withindepression 120. This feature facilitates use ofligament body 102 in spanning more than two vertebrae, e.g., three vertebrae.FIG. 4 illustrates this embodiment mounted to the spinal column and spanning three (3) vertebral portions “v1-v3” with themiddle opening 108 having a fastener for attachment to the intermediate vertebrae “v2” and theouter openings 108 havingfasteners 110 mounted to respective vertebrae “v1” “v3”.Depression 120 preferably also defines a transverse dimension “t” which approximates the diameter of thefastener head 114 to facilitate retention of the head with respect to theligament body 102. -
FIGS. 5 and 6 illustrate an alternate embodiment of theartificial ligament 100 ofFIG. 1 .Artificial ligament 200 is substantially similar to theligament 100, but, differs primarily in its dimensioning. More specifically, the length “1” ofligament body 102 is shorter than the length “1” of the embodiment ofFIG. 1 , preferably ranging in length from about 0.75-1.25 inches, more preferably about 1.14 inches. In all other respects, theligament 200 is identical toligament 100 OfFIG. 1 . -
FIG. 7 illustrates another alternate embodiment of the ligament of the present disclosure.Ligament 300 includes a slightarcuate bend 302 or bump adjacent its intermediate portion. The arcuate bend provides a degree of excess material to permit the effective length of the ligament to increase whenligament 300 is placed in tensioned, i.e., the arcuate bend will tend to straighten under extension. Theligament 300 will become increasingly stiffer with a higher tension load. Multiple bends are also envisioned to establish non-linear stiffness. - While the above description contains many specifics, these specifics should not be construed as limitations on the scope of the disclosure, but merely as exemplifications of preferred embodiments thereof. For example, the present prosthetic device disclosed herein may be implanted to repair a variety of bone structures such as the ankle, knee, wrist, etc. Those skilled in the art will envision many other possible variations that are within the scope and spirit of the disclosure.
