No. 6,964,664, which is a continuation of U.S. patent application Ser. No. 09/479,458, entitled “SYSTEM AND METHOD FOR STABILIZING THE HUMAN SPINE WITH A BONE PLATE,” filed Jan. 6, 2000, now U.S. Pat. No. 6,331,179; the contents of applications referenced herein are hereby expressly incorporated by reference for all purposes.
- This disclosure generally relates to spinal fixation systems and the like. This disclosure also generally relates to a spinal plate system that includes a mechanism for fixably attaching heads of fasteners to a spinal plate.
- The use of spinal fixation plates for correction of spinal deformities and for fusion of vertebrae is well known. Typically, a rigid plate is positioned to span bones or bone segments that need to be immobilized with respect to one another. Bone screws may be used to fasten the plate to the bones. Spinal plating systems are commonly used to correct problems in the lumbar and cervical portions of the spine, and are often installed posterior or anterior to the spine.
- Spinal plate fixation to the cervical portion of the spine may be risky because complications during surgery may cause injury to vital organs, such as the brain stem or the spinal cord. When attaching a fixation plate to a bone, bone screws are placed either bi-cortically (i.e., entirely through the vertebrae such that a portion of the fastener extends into the spinal cord region) or uni-cortically (i.e., the fastener extends into but not through the vertebrae). Uni-cortical positioning of bone screws has grown in popularity because it is generally safer to use. Bi-cortical fasteners are intended to breach the distal cortex for maximum anchorage into the bone; however, this placement of the fasteners may place distal soft tissue structures at risk. Fastener placement is particularly important in anterior cervical plate procedures because of the presence of the spinal cord opposite the distal cortex. Unfortunately, uni-cortical fasteners may move from their desired positions because of the soft texture of the bone marrow. In fact, the portion of the bone surrounding such fasteners may fail to maintain the fasteners in their proper positions. The result is backout of the fastener.
- Backout of the fastener is particularly problematic when two fasteners are implanted perpendicular to the plate. When the fasteners are placed in such a manner, backout may occur as a result of bone failure over a region that is the size of the outer diameter of the fastener threads. To overcome this problem, two fasteners may be angled in converging or diverging directions with respect to each other within the bone. The amount of bone that is required to fail before backout may occur is increased by this configuration as compared to fasteners that are implanted in parallel. Although positioning convergent or divergent fasteners in a bone reduces the risk of backout, backout may still occur.
- Backout may damage internal tissue structures and cause complications if the dislocated fastener penetrates the tissue structures. For example, if backout occurs, the fastener might breach the esophageal wall of the patient. Such a breach may permit bacterial contamination of surrounding tissues, including the critical nerves in and around the spinal cord. Such a breach could be fatal.
- In an attempt to reduce the risk of damage to internal tissue structures, some cervical fastener plate systems have uni-cortical fasteners that attach both to the bone and to the plate. If a fastener does backout, the fastener remains connected to the plate so that it does not contact internal tissue structures. U.S. Pat. No. 5,364,399 to Lowery et al. describes one such system and is incorporated by reference as if fully set forth herein. The Lowery et al. plating system includes a locking fastener at each end of the plate. The locking fastener engages the head of the bone screw to trap the fastener within a recess of the plate. Since the locking fastener is positioned over portions of the bone screws, the locking fastener may extend above the upper surface of the plate. Thus, the locking fastener may come into contact with internal tissue structures, such as the esophagus.
- Another plating system that includes a fastener-to-plate locking mechanism is the Aline.™. Anterior Cervical Plating System sold by Smith & Nephew Richards Inc. in Memphis, Tenn. A description of this system can be found in the Aline.™. Anterior Cervical Plating System Surgical Technique Manual by Foley, K. T. et al., available from Smith & Nephew Richards Inc., September 1996, pp. 1-16 and is incorporated by reference as if fully set forth herein. The bone screws of this system have openings within each bone screw head for receiving a lock fastener coaxially therein. Each bone screw may be inserted into a bone such that the head of the fastener is positioned within a hole of a plate placed adjacent to the bone. The head of each bone screw is slotted so that portions of the head are deflected toward the plate during insertion of the lock fastener within the opening of the bone screw. Positioning and inserting a lock fastener within the opening can be difficult due to the small size of the lock fastener. The surgeon may be unable to hold onto the lock fastener without dropping it. If a lock fastener falls into the surgical wound, it may be difficult to retrieve. In some instances, the lock fastener may be unretrievable.
- An implant system may be used to immobilize a portion of a human spine. The implant system may include a plate comprising end holes, midline holes, fasteners, and expandable/contractible rings. The fasteners and rings may include mechanisms for anchoring or locking the fastener heads within the rings to inhibit backout of the fastener.
- The end holes extend from an upper surface to a lower surface of the plate. The end holes may be disposed in pairs at opposite ends of the plate. Each end hole receives at least a portion of a head of a fastener. Herein, “fastener” means any elongated member, threaded or non-threaded, which is securable within a bone. Fasteners include, but are not limited to screws, nails, rivets, trocars, pins, and barbs. The fastener may be a bone screw. A fastener may have a fastener head. The fastener head typically includes an opening adapted to mate with a tool. The tool allows the insertion of the fastener into a bone. Each end hole may also be spherically contoured to permit the fastener to be “obliquely angulated” relative to the plate. Herein, “obliquely angulated” means that the fastener may be positioned throughout a wide range of angles relative to an axis that is perpendicular to the plate. Obliquely angulating a fastener into a bone may reduce the risk of backout of the fastener.
- The expandable/contractible rings may be sized so that a ring seats within an end hole between the plate and the fastener. The inner surface of each ring may be shaped to mate with a fastener head while the outer surface may be shaped to mate with the inside surface of an end hole. The outer surface of each fastener head may be tapered so that an upper portion of the head is larger than a lower portion of the head. The inner surface of the ring may have a taper that generally corresponds to the taper of the fastener head.
- Each ring may also have a gap that extends vertically through the ring to make the ring more readily expandable and contractible. During insertion of the fastener head into the ring, the fastener head exerts force against the ring to expand the ring against the inner surface of the hole. Expanding the ring against the inner surface of the hole may securely fix the fastener to the plate.
- The fastener head and the ring may include a locking mechanism to attach the fastener head to the plate. The locking mechanism may inhibit backout of the fastener head from the ring if the fastener loosens in the bone. The locking mechanism may also inhibit the fastener head from contacting adjacent tissue structures since the locking mechanism attaches the fastener head to the plate. In some embodiments, there is tolerance for some freedom of movement in an axial direction between a locking mechanism and a fastener head. The availability of some axial movement may allow the fastener to back out or loosen slightly from the bone during a normal period of adjustment after implantation of a spinal fixation system.
- Midline holes may be formed through the plate at various locations along a midline axis extending across the plate. The surface of the plate that surrounds each midline hole may be tapered. Further, the heads of fasteners that may be positioned within the plates may have tapered outer surfaces that generally correspond to the tapered surface of the plate. Thus, when such a fastener head is inserted into a midline hole, the shape of the plate causes the fastener to become fixably attached to the plate in a position that is substantially perpendicular to the plate. Midline holes may be used to attach a bone graft to the bore plate. Oblique angulation of fasteners positioned within the midline holes may not be required.
- The bone plate may have one or more spikes located on the surface of the plate that faces the spinal column. Spikes may be disposed in pairs at opposite ends of the plate proximate the end holes. The spikes may be tapped into the bone to help inhibit the bone plate from slipping during surgical implantation.
- Prior to surgical implantation of the spinal plate system, the expandable/contractible rings may be placed within the end holes of the plate. The plate may then be positioned adjacent to a portion of the spine that requires spinal fixation. Holes may be drilled and/or tapped at desired angles into portions of the bone underlying the end holes of a plate. Fasteners may be inserted through the end holes into the holes in the bone. The heads of the fasteners may be positioned within the end holes such that the rings surround at least a portion of the heads. The rings may lock the fasteners in place without occupying regions outside of the end holes. Further, since the rings are pre-positioned within the end holes, surgeons do not have to worry that they may drop the rings during insertion of the rings into the end holes of the plate.
- In one embodiment, a locking mechanism secures a fastener head to a ring. A locking mechanism may have a top and one or more flexible arms that angle downwards and outwards from the top. The ends of the arms have prongs that are substantially parallel to the top of the locking mechanism. A locking mechanism in a compressed configuration, fits into an opening formed in the head of a fastener. The prongs of the locking mechanism fit within holes located near the bottom of the opening. The holes extend from the outer surface of the head to the opening. When the prongs are positioned in the holes, the prongs extend through the holes so that the locking mechanism is in an extended configuration. The prongs that extend out of the head of the fastener fit within a groove on the inner surface of the ring to enhance the connection between the fastener and the ring.
- The locking mechanism may be inserted in the fastener head prior to the surgical procedure to avoid the risk of dropping the locking mechanism during the surgical procedure. An insertion and extraction tool retracts the prongs on the locking mechanism into the head during insertion or extraction of a fastener. The tool may include a handle, a shaft, and a hollow driver head shaped to match a drive section of the opening on the fastener head. Inserting the driver head into the opening slides the head over the locking mechanism and compresses the shafts of the locking mechanism. Compressing the shafts of the locking mechanism retracts the prongs into the fastener head. To insert a fastener into a bone, the user inserts the fastener into the bone until the head is fully inserted in the ring. Removing the driver head from the opening causes the shafts of the locking mechanism to expand outwards so that the prongs extend out of the holes into the fastener head.
- To remove a fastener that has a locking mechanism, the user inserts the driver head of the insertion and extraction tool into the opening of the fastener head. The driver head compresses the shafts of the locking mechanism and causes the prongs to retract within the fastener head. The user may then remove the fastener from the bone.
- In another embodiment, a tapered fastener head locks into a ring by one or more fingers on the ring that snap into grooves on the fastener head. L-shaped slots cut into the top of the ring may define the fingers. The fingers have spring-like action so that the fingers snap into the grooves on the fastener head when a fastener head is inserted into the ring. As the fastener head passes into the ring, the tapered outer surface of the head expands the ring against the inner surface of the plate. When the groove on the fastener head reaches the fingers, the fingers snap into the groove, fixing the fastener in the ring and helping to inhibit backout.
- In another embodiment, a fastener head locks to a ring by one or more ridges on the ring that snap into grooves on the fastener head. Notches cut into the top of the ring may form paddles. A ridge may extend along an inside surface of each paddle proximate the top of the ring. The paddles have a spring-like action so that the ridges snap into the grooves on the fastener head during insertion of the fastener head into the ring. The ridges of the ring residing within a groove of the fastener head may fix the fastener in the ring and help inhibit backout of the fastener.
- An extraction tool module fits over an insertion tool and allows the retraction of the ring ridges from the fastener head. The insertion tool includes a handle, a shaft, and a driver head shaped to match the opening on the fastener head. The extraction module slides over the shaft of the insertion tool. The extraction module may include a handle and an extraction head. The extraction head may include a tip that slides over the fastener head and contacts the ends of the paddles. The outer surface of the tip tapers. As the extraction module is pushed down, the tapered surface of the tip forces the paddles outwards and disengages the ridges on the paddles from the grooves on the fastener head. Disengaging the ridges on the paddles from the grooves on the fastener head allows the fastener to be backed out of the bone.
- Using a locking mechanism between the fastener head and the ring may result in a strong connection between the fastener and the plate. Even if the shank of a fastener loosens within the bone, the fastener head will tend to remain within the hole of the plate so as not to protrude from the plate into surrounding body tissue. Allowing some axial freedom of movement for the fastener head in the ring may allow the fastener to back out slightly during an adjustment period after installation of the spinal fixation system.

It should be understood, however, that the drawings and detailed description thereto are not intended to limit the invention to the particular form disclosed, but to the contrary, the intention is to cover all modifications, equivalents and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
- Referring to the drawings, and particularly to
FIG. 1 , a spinal plating system is designated generally as 20. Thespinal plating system 20 may be used to correct problems in the lumbar and cervical portions of the spine. For example, theplating system 20 may be implanted into the occiput bone that is located at the base of the skull. Theplating system 20 may also be installed anterior to the spine. Thespinal plating system 20 includesplate 22 that is placed adjacent to a portion of the spine and spans at least two vertebrae.Plate 22 may include fourend holes 24, located at corners of the plate. End holes 24 pass vertically throughplate 22 such that the holes extend from anupper surface 26 to alower surface 28 of the plate as depicted inFIG. 2 . End holes 24 are configured to receive rings 30.Fasteners 32 fit within therings 30. Herein, “fastener” means any elongated member, threaded or non-threaded, which is securable within a bone. Fasteners include, but are not limited to screws, nails, rivets, trocars, pins, and barbs. The fastener may be a bone screw.Rings 30 fixedly attach fastener heads 34 offasteners 32 toplate 22.Gap 36 may exist in each of therings 30. Agap 36 allows for expansion and contraction of aring 30. Ring contraction allows aring 30 to be easily inserted into anend hole 24 of theplate 22. - The
spinal plating system 20 may also include one or morecentral holes 38 that extend vertically throughplate 22. One of thecentral holes 38 may be located at about the mid-point of theplate 22.Head 40 offastener 42 is positioned within one of thecentral holes 38. Multiplecentral holes 38 provide a surgeon with options as to the most desirable location for placement of afastener 42.Fastener 42 may be used to connectplate 22 to a bone graft (not shown). -
FIG. 2 shows afastener 42 within one of thecentral holes 38 ofplate 22.Fastener 42 may includehead 40 andshank 44. Theshank 44 extends from the base ofhead 40. In one embodiment, the inner surface of acentral hole 38 tapers so that the hole is larger atupper plate surface 26 than at thelower plate surface 28. The outer surface of thefastener head 40 has a taper that generally corresponds to the taper of thecentral hole 38. During implantation of afastener 42 into a bone graft, theshank 44 of thefastener 42 is inserted into a hole that has been formed in the bone graft underhole 38. Because the lower portion ofhole 38 is smaller than the upper portion of thefastener head 40,fastener 42 may become locked into place within thecentral hole 38 once the fastener has been inserted to a desired depth within the bone graft. Thebone plate 22 may havespikes 45 extending from thelower plate surface 28. - As shown in
FIG. 2 , theplate 22 may have a curvature. The curvature may enhance fixation of theplate 22 to a bone. Thebone plate 22 may have one ormore spikes 45 located on the surface of the plate that faces the bone. Thespikes 45 may be disposed in pairs at opposite ends of the plate proximate the end holes 24. Thespikes 45 may be tapped into the bone to help inhibit thebone plate 22 from slipping during surgical implantation. -
FIG. 3 depicts a cross-sectional view of an embodiment of afinal plating system 20 wherein a pair offasteners 32 are in a converging configuration.FIG. 4 depicts a cross-sectional view of an embodiment of a spinal plating system wherein a pair offasteners 32 is in a diverging configuration.Ring 30 fits into ahole 24 betweenplate 22 andfastener head 34.Inner surfaces 46 ofholes 24 may have arcuate or spherical contours. Outside surfaces 48 ofrings 30 may have arcuate or spherical contours that substantially correspond to the contours of theinner surfaces 46 of theholes 24. Having a contoured ringouter surface 48 that substantially corresponds to the contour of theinner hole surface 46 allows aring 30 positioned in ahole 24 to be capable of polyaxial rotation within theend hole 24. - The combination of
ring 30 withinend hole 24 functions like a ball and socket since the ring may be swiveled or polyaxially rotated within the end hole. The ability of thering 30 to rotate polyaxially within theend hole 24 allows afastener 32 to be positioned through theplate 22 at various angles with respect to an axis that is perpendicular to the plate.FIGS. 3 and 4 show angle A for particular fastener configurations. The angle A is defined between thelongitudinal axis 50 of thefastener 32 andimaginary axis 52 that is perpendicular to theplate 22. The angle A may range from 0 to about 45 degrees, preferably from about 0 to about 30 degrees, and more preferably from 0 to about 0 and 15 degrees. -
Fasteners 32 may also be set in positions such that the fasteners are non-planar with respect to a latitudinal plane extending throughplate 22. For example, onefastener 32 may be positioned out of the page and anotherfastener 32 may be positioned into the page, as depicted inFIGS. 3 and 4 .Fasteners 32 set in diverging or converging directions in the end holes 24 may reduce the possibility of backout. Further, the use ofrings 30 to fixedly attachfasteners 32 to plate 22 may inhibit damage to tissue structures by any fasteners that do loosen within a bone, since such fasteners would remain attached to theplate 22.Fasteners 32 may be placed in uni-cortical positions within a bone since the problem of fastener backout is reduced by having obliquely angulated fasteners in converging or diverging configurations. -
Ring 30 may at least partially surroundshead 34 offastener 32 positioned withinend hole 24. Ashank 54 offastener 32 may include threading 56 to allow the fastener to be inserted into a bone whenfastener 32 is rotated. As depicted inFIG. 1 ,fastener head 34 may include acavity 58 that extends from the top of the head to an inner portion of the head.Cavity 58 may be shaped to receive an end of a tool that inserts or removes thefastener 32 from a bone. The tool end may be in the form of a hex wrench, a star wrench or a screwdriver blade. -
Inner surface 60 ofring 30 andouter surface 62 ofhead 34 may have mating tapered surfaces, as depicted inFIG. 3 andFIG. 4 . In one embodiment, the bottom portion ofhead 34 may be smaller than the upper portion of anunstressed ring 30, while the upper portion of the head may be larger than the upper portion of the ring. Asfastener 32 is inserted into a bone,head 34 applies a radial force to ring 30 which causes the ring to expand within theend hole 24. Expanding thering 30 increases the size ofgap 36 and may cause theoutside surface 46 of the ring to abut againstinner surface 46 of theend hole 24. An interference fit forms betweenfastener head 34,ring 30, andplate 22 in which these elements fit together such that each element obstructs the movement of the other elements. Hoop stress ofring 30 onhead 34 fixedly attachesfastener 32 toplate 22. -
Ring 30 may be capable of swiveling within ahole 24 so that one portion ofring 30 is adjacent to theupper surface 26 ofbone plate 22 while another portion of the ring lies adjacent to thelower surface 28 of the bone plate. In one embodiment,ring 30 may sufficiently thin to reside withinend hole 24 without extending beyond the upper orlower surface bone plate 22. Thering 30 andfastener head 34 remain withinend hole 24 so that thespinal plating system 20 may have a minimal profile width. Having rings 30 and the fastener heads 34 which do not extend above theupper surface 26 or below thelower surface 28 ofplate 22 may prevent the rings and heads from contacting adjacent tissue structures. In other embodiments, however,fasteners 32 may be capable of being angulated relative tobone plate 22 such that therings 30 extend from the end holes 24 beyond upper and/or lower surfaces of the bone plate. - In one embodiment, the
spinal plating system 20 is prepared for surgical implantation by positioning rings 30 within end holes 24. During the surgical procedure, holes may be drilled and tapped into the bones to whichplate 22 is to be attached.Plate 22 may then positioned adjacent to the bones and over the holes in the bones.Fasteners 32 may be placed through aring 30 and into the bone holes. Eachfastener 32 may be obliquely angulated into theplate 22. Thefasteners 32 may be inserted into the bone until the fastener heads 34 expand therings 30 against theinner surfaces 46 of theholes 24; thus fixing the fasteners to the rings, and the rings to theplate 22. If necessary, afastener 42 may be positioned in one of thecentral holes 38. - In one embodiment,
ring 30 has an outer width that is less than or about equal to the width of anend hole 24 inbone plate 22 at a location between anupper surface 26 andlower surface 28 of the bone plate. The width of eachend hole 24 proximate the upper andlower surfaces bone plate 22 is less than or about equal to an outer width ofring 30. The width of the ring may inhibit a ring positioned in a hole from falling out of the hole. Prior to surgery, aring 30 may be positioned within eachend hole 24 ofbone plate 22. When seated withinhole 24,ring 30 may be capable of swiveling within the hole, but the ring is inhibited from falling out of the hole because of reduced width of the hole proximate the upper andlower surfaces plate 22. A surgeon may use abone plate 22 havingrings 30 positioned withinholes 24 prior to surgery. Alternatively, rings 30 may be manually positioned withinholes 24 during surgery. - Texturing the
outer surface 48 of aring 30 or aninner surface 46 of ahole 24 may further inhibit movement of afastener 32 with respect to abone plate 22. Both surfaces may be textured to more effectively inhibit movement of afastener 32 with respect to abone plate 22. During manufacturing procedures, theouter surface 48 ofring 30 and the inner surface ofend hole 24 are formed as relatively smooth surfaces. While the friction between these smooth surfaces tends to be sufficient to maintainfastener 32 in a fixed position with respect toplate 22; under stressful conditions ring 30 may rotate withinhole 24. By providing at least one textured surface, the coefficient of friction betweenhole 24 andring 30 is increased. The increase in friction betweenhole 24 andring 30 may help to inhibit fastener movement relative to plate 22. - Several types of textured surfaces may be used to increase the coefficient of friction between
ring 30 andhole 24. In general, any process that transforms a relatively smooth surface into a textured surface having an increased coefficient of friction may be used. Methods for forming a textured surface include, but are not limited to: sanding, forming grooves within a surface, shot peening processes, electric discharge processes, and embedding of hard particles within a surface. - A shot peening process for forming a textured surface is described in U.S. Pat. No. 5,526,664 to Vetter which is incorporated by reference as if set forth herein. In general, a shot peening process involves propelling a stream of hardened balls, typically made of steel, at a relatively high velocity at a surface. To create a pattern upon an area of the surface the stream is typically moved about the surface. The speed by which the stream is moved about the surface determines the type of textured surface formed.
- An electrical discharge process is based on the principle of removal of portions of a metal surface by spark discharges. Typically a spark is generated between the surface to be treated and an electrode by creating potential differential between the tool and the electrode. The spark produced tends to remove a portion of the surface disposed between the electrode and the surface. Typically, the electrode is relatively small such that only small portions of the surface are removed. By moving the electrode about the surface numerous cavities may be formed within the surface. Typically these cavities are somewhat pyramidal in shape. Various patterns may be formed within the surface depending on how the electrode is positioned during the discharge. Electric discharge machines are well known in the art. A method for forming a frictional surface within a metal surface using an electric discharge process is described in U.S. Pat. No. 4,964,641 to Miesch et al., which is incorporated by reference as if set forth herein.
- Embedding hardened particles in a surface produces a textured surface. A method for embedding hardened particles in a metal surface is described in U.S. Pat. No. 4,768,787 to Shira, which is incorporated by reference as if set forth herein. The method of Shira involves using a laser or other high-energy source to heat the surface such that the surface melts in selected areas. Just before the molten area re-solidifies, a stream of abrasive particles is directed to the area. In this manner some of the particles tend to become embedded within the molten surface. The particles typically have a number of sharp edges that protrude from the surface after the particles have been embedded within the surface.
- Any of the above methods of texturing may be used in combination with another method. For example, the
inner surface 46 ofhole 24 may be textured using a pattern of grooves. Theouter surface 48 ofring 30, however, may be textured using an electrical discharge method. When coupled together the textured surfaces ofhole 24 andring 30 may interact with each other to provide additional resistance to movement of the ring within the hole. -
FIG. 5 illustrates an embodiment offastener 100. Thefastener 100 may includefastener head 102, opening 104,optional grooves 106, holes 108,shank 110 andthreads 112.Opening 104 accepts a drive tool, such asdrive tool 114, which is described below. Theopening 104,grooves 106 andholes 108 acceptlocking mechanism 116, as described below.Holes 108 extend from theouter surface 118 ofhead 102 to theopening 104. In one embodiment, theouter surface 118 is substantially cylindrical. In another embodiment, thehead 102 tapers from a widest portion near the upper surface of the head to a narrowest portion near theshank 110. -
FIG. 6 is a side view of thehead 102 of an embodiment offastener 100 showingholes 108 andoptional rim 120.Rim 120 may serve to limit the insertion offastener 100 into aring 30 during use. -
FIG. 7 is a top view of thehead 102 of afastener 100 withoptional grooves 106.FIG. 8 shows an alternate embodiment offastener 100 having a hexagonal shape opening 104 and no grooves. -
FIG. 9 illustrates alocking mechanism 116 used withfastener 100.Locking mechanism 116 includes top 122 withshafts 124 extending downwards and outwards from the top.Prongs 126 are located at ends ofshafts 124.Prongs 126 may be substantially parallel to each other and also may be substantially parallel to thelocking mechanism top 122. Theshafts 124 have a spring-like action which allows theshafts 124 to be compressed. The spring-like action also allows the shafts to return to an original configuration when not compressed. -
FIG. 10 illustrates an embodiment of aring 130 that may be used in combination withfastener 100 andlocking mechanism 116.Ring 130 includesgroove 132.Groove 132 engagesprongs 126 on lockingmechanism 116 to securefastener 100 inring 130 after insertion.Gap 36 inring 130 allows the ring to contract during insertion of thering 130 into anend hole 24 of thebone plate 22.Gap 36 also allowsring 130 to be expanded by thehead 102 offastener 100 in thering 130 to abut the ring against theinner surface 46 of theend hole 24. Abutting thering 130 against theinner surface 46 of theend hole 24 may fix the position offastener 32 relative to thebone plate 22. -
FIG. 11 illustratestool 114. Thetool 114 may be used during the insertion and extraction of afastener 100 andlocking mechanism 116. The insertion/extraction tool 114 includes ashaft 172. One end ofshaft 172 may include ahandle 174 for turning the tool during insertion and removal of afastener 100.FIG. 11 shows a modified T-handle 174 coupled to theshaft 172, but any type of handle that allows torque to be applied to the fastener during insertion and removal may be used. At an opposite end ofshaft 172 fromhandle 174 isdriver head 176. The outer surface ofdriver head 176 may be shaped to complement the shape of opening 104 in the head of thefastener 100.Driver head 176 may be inserted into theopening 104 of thefastener 100. The fastener may be inserted in anend hole 24 of abone plate 22 and into a bone by rotating insertion/extraction tool 114.Driver head 176 includescavity 178. The inner surface of the cavity may slide over and compress theshafts 124 andprongs 126 of alocking mechanism 116. -
FIG. 12 a shows a bottom view of an embodiment of adriver head 176 of an insertion/extraction tool 114. The driver head ofFIG. 12 a may be used with the type offastener head 102 shown inFIG. 7 . Thedriver head 176 hascavity 178 which allows the driver head to slide over and compress alocking mechanism 116. Thedriver head 176 includesridges 180 for engagingcomplementary grooves 106 in theopening 104 of afastener head 102.FIG. 12 b shows an alternate embodiment of adriver head 176 of an insertion/extraction tool 114. The driver head ofFIG. 12 b may be used with the type offastener head 102 shown inFIG. 8 . Thedriver head 176 hascavity 178 which allows the driver head to slide over and compresses alocking mechanism 116. Thedriver head 176 may be hexagonal shaped to mate with opening 104 of afastener head 102. -
FIG. 13 shows a cross sectional view of an embodiment of afastener 100,locking mechanism 116, and insertion/extraction tool 114 during the insertion process.Driver head 176 inserts into opening 104 offastener head 102.Shafts 124 oflocking mechanism 116 are compressed withincavity 178 ofdriver head 176. The compression ofshafts 124causes prongs 126 to retract inholes 108, which allowfastener head 102 to be inserted into aring 130 without interference byextended prongs 126. When insertion/extraction tool 114 is removed, theshafts 124 uncompress, which causes theprongs 126 to extend out ofholes 108. -
FIG. 14 shows a cross sectional view of an embodiment of afastener 100,locking mechanism 116, andring 130 after the fastener has been fully inserted in the ring and the insertion/extraction tool 114 has been removed.Shafts 124 oflocking mechanism 116 are uncompressed, allowingprongs 126 to extend out ofholes 108 infastener head 102.Prongs 126 extend intogroove 132 on thering 130. - To remove a threaded
fastener 100 fromring 130, insertion/extraction tool 114 is inserted in theopening 104 infastener head 102 to compress theshafts 124 of thelocking mechanism 116. Compressing theshafts 124 causes theprongs 126 to retract throughholes 108 and removes the connection between the prongs and thering 130. Thetool 114 may then be rotated to remove thefastener 100 from the bone. - After insertion of a
fastener 100 andlocking mechanism 116 into a bone, if thefastener 100 becomes loose within the bone, fastener backout from the bone plate may be resisted by the locking mechanism-groove connection betweenlocking mechanism 116 and thering 130. Thus, even iffastener shank 110 loosens within the bone, thefastener head 102 will tend to remain withinring 130 in thehole 24 of theplate 22. There may be some freedom of movement in the connection between theprongs 126 and thegroove 130 to allow afastener 100 to back out slightly from a bone after insertion. - During the surgical procedure for attaching a bone plate to bones using the devices depicted in
FIGS. 5-14 , holes may be drilled and tapped into the bones to which thebone plate 22 is to be attached. Thebone plate 22 may be positioned adjacent to the bones.Rings 130 may be positioned within eachend hole 24 before or during the surgical procedure. Afastener 100, with a pre-inserted locking mechanism, may be positioned through aring 130. An insertion/extraction tool 114 may be inserted in theopening 104 of threadedfastener 100 to compress thelocking mechanism 116 within the cavity of the driver head of the tool. Compressing thelocking mechanism 116 retracts theprongs 126 of the locking mechanism within thefastener opening 104. Thefastener 100 may then be rotated to insert thefastener 100 into a bone. As thefastener 100 is rotated,fastener head 102 moves into thering 130. Movement ofhead 102 intoring 130 causes the ring to expand against theend hole 24 to fix thefastener 100 relative to theplate 22. Once thefastener 100 is fully inserted, insertion/extraction tool 114 is removed. Removing thetool 114 causes thelocking mechanism 116 to uncompress so that theprongs 126 extend through theholes 108 in thefastener head 102 and engage ring thegroove 132 in thering 130.Fasteners 100 may be inserted through the remaining end holes 24 and into bone to securely attach theplate 22 to the bones. -
FIG. 15 illustrates an embodiment of afastener 200 withfastener head 202 havinggroove 204. When afastener 200 is inserted through aring 230 positioned in aplate 22, thegroove 204 may engagefingers 232 on ring 230 (the ring shown inFIGS. 19 and 20 ) to secure thefastener 200 within thering 230.Fastener 200 may include thehead 202 andshank 206 with threading 208.Head 202 may include opening 210 configured to accept a driving tool. - The engagement of a
finger 232 of aring 230 ongroove 204 may inhibitfastener 200 from backing out of the ring after insertion of the fastener into theplate 22. In an embodiment, the outer surface ofhead 202 is substantially cylindrical. In another embodiment, as shown inFIG. 16 , thehead 202 may taper. The widest portion of thehead 202 may be near the top surface of the head, and the narrowest portion may be near theshank 206. -
FIG. 17 illustrates an embodiment of afastener 200 which hasradial slots 212 extending from the outer surface of the head into theopening 210. Theradial slots 212 may allow a portion ofhead 202 to contract during insertion. Theradial slots 212 may also be used to engage a portion of a drive head of an insertion/extraction tool (not shown). -
FIGS. 15 , 16, and 17 illustrate fastener heads 202 wherein thegrooves 204 are rims along top edges of the heads.FIG. 18 illustrates an embodiment of afastener 200 wherein thegroove 204 is located at a position along the side of thefastener head 202. Thegroove 204 may be located at any position along the side of thefastener head 202. When thefastener head 202 is driven through aring 230, the interaction of the fastener head, the ring, and theend hole 24 allowsfingers 232 of the ring to snap into the groove 214. Thefingers 232 may secure thefastener head 202 to thering 230. -
FIGS. 19 and 20 show perspective views of embodiments ofring 230 that may be used with fasteners having a groove.Ring 230 may include bottom 234, top 238, anouter surface 48, aninner surface 60,gap 36, andslots 240 andnotches 242. Theslots 240 andnotches 240 may form thefingers 232.Gap 36 may allowring 230 to contract. Contraction of thering 230 may facilitate the insertion of the ring into anend hole 24 in abone plate 22.Gap 36 may also allow thering 230 to expand against theend hole 24 when afastener head 202 passes into the ring. Expansion of the ring against thehole 24 fixes thefastener 200 relative to thebone plate 22. - In some embodiments,
outer surface 48 of thering 230 may be textured to increase the coefficient of friction betweenring 230 and thehole 24. In some embodiments,inner surface 60 of thering 230 may be tapered to match a tapered head of afastener 200. Having tapered surfaces may facilitate the expansion of ring in anend hole 24 during insertion of the fastener into thebone plate system 20. - The shape of the
end hole 24 may push thefingers 232 inwards past the edge of thegroove 204 of afastener 200 when the groove is inserted into aring 230 so that the groove passes an upper edge of thering slots 240. The inward positionedfingers 232 may inhibitfastener 200 from backing out of thering 230 and thehole 24. When thefastener 200 is inserted into thering 230, thefastener head 202 may expand theoutside surface 48 of the ring against theinner surface 46 of theend hole 24 to fix thefastener 200 to thering 230, and the ring to theplate 22. -
FIG. 21 is a perspective view of an embodiment of a ring that may be used withfasteners 200 that haverims 204, such as the fasteners shown inFIGS. 15-17 .Ring 430 may include bottom 432, top 434,outer surface 48,inner surface 60,gap 36,notches 436, andridges 438.Notches 436 divide thering 430 into segments or paddles 440.Notches 436 andgap 36 may allowring 430 to contract, facilitating the insertion of the ring into ahole 24 of abone plate 22.Notches 436 andgap 36 may also allowring 430 to expand when afastener head 202 passes into the ring to fix the position of the fastener relative to thebone plate 22.Notches 436 may also allowpaddles 436 to bend outwards during insertion of afastener 200. Theouter surface 48 and/or theinner surface 60 may be textured. The inner surface of thering 430 may be tapered to correspond to the taper of afastener head 202. -
FIG. 22 illustrates an embodiment of an insertion tool/extraction tool 450 for use with afastener 200 andring 430. Insertion/extraction tool 450 may includeshaft 452, handle 454,driver head 456, andextraction member 458. At one end ofshaft 452 is handle 454 for turning the tool during insertion and removal of afastener 200. The illustration shows a T-handle, but any other type of handle that allows sufficient torque to be applied to thefastener 200 to allow for insertion or removal of the fastener may be used. At the opposite end ofshaft 452 fromhandle 454 isdriver head 456. The outer surface ofdriver head 456 may be shaped complementary to the shape of theopening 210 in thehead 202 of thefastener 200. - The
extraction member 458 shown inFIG. 22 may includegrip 459,passage 460, (shown inFIG. 23 c),tip 462, andextraction head 464. Thepassage 460 extends through thegrip 459 and theextraction head 464. During the insertion process,extraction member 458 may be removed fromshaft 452. To extract a fastener from aring 430,extraction member 458 may be slid back on toshaft 452.Driver head 456 is inserted into theopening 210 of thefastener 200.Extraction member 458 slides downshaft 452 untiltip 462 ofextraction head 464 contacts the top of thering 430. Downwards pressure on theextraction member 458 forces paddles 440 of thering 430 outwards, and disengages theridge 438 on thepaddles 440 from therim 204 on thefastener head 202. Thefastener 200 may then be backed out of theplate 22 by rotating theshaft 452 with thehandle 454. Preferably,rotating shaft 452 does not rotate theextraction member 458. -
FIGS. 23 a, 23 b, and 23 c show partial cross sectional views of a threadedfastener 200,ring 430, and insertion/extraction tool 450 during the insertion and extraction processes. Referring toFIG. 23 a,driver head 456 of insertion/extraction tool 450 is inserted in opening 210 offastener head 202.Ring 430 is positioned inside ahole 24 in a bone plate and the bone plate is positioned on a bone (bone and bone plate not shown).Fastener 200 is screwed into the bone until the outer surface offastener head 202 contacts the surfaces of thepaddles 440. The tapering of the outer surface offastener head 202 provides a ramping force on the surfaces of thepaddles 440, to bend the paddles outwards asfastener 200 is screwed farther into the bone. - In
FIG. 23 b,fastener 200 has been screwed in to the desired depth.Fastener head 202 penetratesring 430 far enough to allowridges 438 to snap ontorim 204 onfastener head 202.Driver head 456 of insertion/extraction tool 450 is shown still inserted inopening 210 prior to removal from the opening. After insertion, if thefastener 200 becomes loose within the bone, fastener backout from the bone plate may be resisted by the ridge-rim connection betweenfastener head 202 andring 430. Thus, even if the fastener shank loosens within the bone, thefastener head 202 will tend to remain withinring 430 in thehole 24 of theplate 22 so as not to protrude from the plate into surrounding body tissue. In some embodiments, there may be some freedom of movement in the connection between theridges 438 on thepaddles 440 and therim 204 to allow afastener 200 to back out slightly from a bone after insertion. Typically, the freedom of movement is limited so that thefastener head 202 may not protrude from theplate 22. -
FIG. 23 c shows insertion/extraction tool 250 being used to remove afastener 200. Driver head 256 is inserted in opening 210 offastener 200.Extraction head 464 is slid downshaft 452 of insertion/extraction tool 450 until the sloped surface oftip 462 applies a wedging force against the sloped upper surfaces ofpaddles 440. The wedging force bends thepaddles 440 outwards to disengage theridges 438 from therim 204.Fastener 200 may then be backed out of the bone, thering 430 and theplate 22. - The plate, fasteners, and locking mechanisms may be made of steel (e.g, stainless steel), titanium, steel alloys or titanium alloys. These materials are generally nontoxic, bio-compatible, strong, and non-corrosive. Other materials that have these properties may also be used. The plate and the rings may be made of a number of bio-compatible materials including metals, plastics, and composites.
