FIG. 1 shows a cross-sectional view of asystem 100 for affixing astratum 20 tobone 50. Thesystem 100 has astratum 20 having afirst surface 20 a, asecond surface 20 b, and at least onehole 30 extending between thefirst surface 20 a and thesecond surface 20 b, wherein thesecond surface 20 b is configured to engage at least a portion of thebone 50. Thesystem 100 further has afastener 10 configured to pass at least partially through the at least onehole 30 and engage at least a portion of thebone 50, wherein thestratum 20 is further configured to deflect, allowing thefastener 10 to pass at least partially through thehole 30. In the context where thestratum 20 may be a spinal plate, for example, the stratum may be used to fuse adjacent vertebrae together in a relatively fixed relationship. - In the
system 100 ofFIG. 1 , thefastener 10 has a length and a width, the length being greater than the width, and a central longitudinal axis. A side view of thefastener 10 ofFIG. 1 is shown inFIG. 2 , which is drawn to scale. Thefastener 10 further has ahead portion 12, anintermediate portion 18, and adistal portion 15. Thedistal portion 15 has aproximal end 16 that is proximate theintermediate portion 18, and adistal end 14 located at the tip of thefastener 10. - In the context of spinal plates, the
fastener 10 may be, for example, a screw. In fact, a screw is shown as thefastener 10 inFIGS. 1 and 2 . In an embodiment where thefastener 10 is a screw, thehead portion 12 is a head of the screw, thedistal portion 15 contains threads of the screw, and theintermediate portion 18 has no threads. The cross section of thefastener 10 may be substantially circular, as is common with screws. As shown inFIGS. 1 and 2 , thehead portion 12 has a width (or diameter in the case of a fastener having a circular cross section) that is the largest of thefastener 10, while theintermediate portion 18 has the smallest width (or diameter). Thedistal portion 15 of thefastener 10 has aproximal end 16 having a first width (or diameter) and adistal end 14 having a second width (or diameter), wherein the first width is greater than the second width. As used herein, the width of each respective section is substantially perpendicular to the central longitudinal axis X-X′ of thefastener 10. - In the embodiment of
FIG. 1 , thesystem 100 shows astratum 20 that is substantially non-rigid, such as, for example, polyetheretherketone (“PEEK”). Such a stratum may be composed solely of PEEK, or contain enough PEEK so as to be non-rigid. Other suitable non-rigid materials may include, but are not limited to polyetherketoneketone (“PEKK”), ultra high molecular weight polyethylene (“UHMWPE”), polyethylene, shape memory metals and other polymers. The term “substantially” as used herein may be applied to modify any quantitative representation which could permissibly vary without resulting in a change in the basic function to which it is related. For example, astratum 20 may be considered substantially non-rigid if can deflect (at the location of the hole 130) upon the insertion of afastener 10 throughhole 30, but rebound to the position or approximate position prior to insertion of thefastener 10. Specifically,system 100 is designed so that theproximal end 16 of thedistal portion 15 of thefastener 10 causes thestratum 20 to deflect as theproximal end 16 of thefastener 10 moves across the at least onehole 30 in thestratum 20 in the direction towards thesecond surface 20 b of thestratum 20.FIG. 1A showssystem 100 as theproximal end 16 of thefastener 10 moves across the at least onehole 30 in thestratum 20 in the direction towards thesecond surface 20 b of thestratum 20, thereby deflecting thestratum 20. -
FIG. 1A illustrates a deflection mechanism that is a type of deflection due to, for example, the characteristics of the material of thestratum 20. In addition to the deflection mechanism illustrated inFIG. 1A , thestratum 20 may deflect in a radial direction so as to enlarge thehole 30. That is, thestratum 20 adjacent to thehole 30 or portions of thestratum 20 adjacent thehole 30 may move in a direction away from thefastener 10, yet remain in the same plane of thestratum 20. In such a mechanism, thestratum 20 deflects in a direction away from and substantially perpendicular to thefastener 10. Such a mechanism is a type of deflection due, for example, the geometry of thestratum 20. - Further, the
distal portion 15 of thefastener 10 has alip 16L that allows passage of theproximal end 16 through the at least onehole 30 in thestratum 20, and prevents inadvertent backing out of thefastener 10, i.e., moving back out of the at least onehole 30 in a direction away from thebone 50. As shown inFIGS. 1 , 1A and 2, thelip 16L is situated at the proximal-most location of thedistal portion 15 of thefastener 10, and also has the largest width (or diameter) over the distal portion of thefastener 10. Also, when thefastener 10 is inserted through thehole 30 on thestratum 20, thestratum 20 starts to deflect when thesurface 16 a of theproximal end 16 of thedistal portion 15 contacts thestratum 20, whereas thestratum 20 prevents inadvertent backing out of thefastener 10 by means of the contact between thesecond surface 20 b of thestratum 20 andsurface 16 b of theproximal end 16 of thedistal portion 15. In the embodiments ofFIGS. 1 , 1A and 2, thefastener 10 is made of a material that allows this function to be accomplished. For example, thefastener 10 may be made of a material (metal or non-metal) that is able to cause thestratum 20 to deflect and rebound, as described above. Some suitable materials include, but are not limited to, Titanium Alloys, commercially available Titanium, stainless steel, PEEK, cobalt chrome (“CoCr”), and shape memory metals. Further, as shown inFIG. 1 , thestratum 20 has arecess 24 surrounding thehole 30 that helps accommodate at least a portion of thehead portion 12 of thefastener 10. -
FIG. 3 shows a cross-sectional view of asystem 200 for affixing astratum 120 tobone 150. Thesystem 200 has astratum 120 having afirst surface 120 a, asecond surface 120 b, and at least onehole 130 extending between thefirst surface 120 a and thesecond surface 120 b, wherein thesecond surface 120 b is configured to engage at least a portion of thebone 150. Thesystem 200 further has a fastener 110 configured to pass at least partially through the at least onehole 130 and engage at least a portion of thebone 150, wherein thestratum 120 is further configured to deflect, allowing the fastener 110 to pass at least partially through thehole 130. - In
system 200 ofFIG. 3 , the fastener 110 has a length and a width, the length being greater than the width, and a central longitudinal axis. The fastener 110 further has ahead portion 112, anintermediate portion 118, and a distal portion 115. The distal portion 115 has aproximal end 116 that is proximate theintermediate portion 118, and a distal end 114 located at the tip of the fastener 110. - In the context of spinal plates, the fastener 110 may be, for example, a screw. In fact, a screw is shown as the fastener 110 in
FIG. 3 . In an embodiment where the fastener 110 is a screw, thehead portion 112 is a head of the screw, the distal portion 115 contains threads of the screw, and theintermediate portion 118 has no threads. The cross section of the fastener 110 may be substantially circular, as is common with screws. As shown inFIG. 3 , thehead portion 112 has a width (or diameter) that is the largest of thefastener 10, while theintermediate portion 118 has the smallest width (or diameter). The distal portion 115 of the fastener 110 has aproximal end 116 having a first width (or diameter) and a distal end 114 having a second width (or diameter), wherein the first width is greater than the second width. As in the embodiments ofFIGS. 1 , 1A and 2, as used herein, the width of each respective section is substantially perpendicular to the central longitudinal axis of the fastener 110. - In the embodiment of
FIG. 3 , thesystem 100 shows astratum 120 that is substantially non-rigid, such as, for example, polyetheretherketone (“PEEK”). Such a stratum may be composed solely of PEEK, or contain enough PEEK so as to be non-rigid. Other suitable materials for thestratum 120 ofFIG. 3 are similar to those that are suitable for thestratum 20 ofFIGS. 1 and 1A . Astratum 120 may be considered substantially non-rigid if can deflect (at the location of the hole 30) upon the insertion of a fastener 110 throughhole 130, but rebound to the position or approximate position prior to insertion of the fastener 110. Specifically,system 200 is designed so that theproximal end 116 of the distal portion 115 of the fastener 110 causes thestratum 120 to deflect as theproximal end 116 of the fastener 110 moves across the at least onehole 130 in thestratum 120 in the direction towards thesecond surface 120 b of thestratum 120. - Further, the distal portion 115 of the fastener 110 has a
lip 116L that allows passage of theproximal end 116 through the at least onehole 130 in thestratum 120, and prevents inadvertent backing out of the fastener 110, i.e., moving back out of the at least onehole 130 in a direction away from thebone 150. As shown inFIG. 3 , thelip 116L is situated at the proximal-most location of the distal portion 115 of the fastener 110, and also has the largest width (or diameter) over the distal portion of the fastener 110. Also, when the fastener 110 is inserted through thehole 130 on thestratum 120, thestratum 120 starts to deflect when thesurface 116 a of theproximal end 116 of the distal portion 115 contacts thestratum 120, whereas thestratum 120 prevents inadvertent backing out of the fastener 110 by means of the contact between thesecond surface 120 b of thestratum 120 andsurface 116 b of theproximal end 116 of the distal portion 115. In the embodiment ofFIG. 3 , as with those illustrated in the previous Figures, the fastener 110 is made of a material that allows this function to be accomplished. For example, the fastener 110 may be made of a material (metal or non-metal) that is able to cause thestratum 120 to deflect and rebound, as described above. As withsystem 100 of the previous figures, with thesystem 200 ofFIG. 3 , thestratum 120 and thelip 116L of the fastener 110 are configured and work in conjunction to allow deflection of thestratum 120 in the direction toward thebone 150, while at the same time, work to not allow deflection in the opposite direction, i.e., to prevent inadvertent backing out of the fastener. Further, as shown inFIG. 3 , thestratum 120 has arecess 124 surrounding thehole 130 that helps accommodate at least a portion of thehead portion 112 of the fastener 110. - All adjustments and alternatives described above are intended to be included within the scope of the invention, as defined exclusively in the following claims. Those skilled in the art also should realize that such modifications and equivalent constructions or methods do not depart from the spirit and scope of the present disclosure, and that they may make various changes, substitutions, and alterations herein without departing from the spirit and scope of the present disclosure. Furthermore, as used herein, the terms components and modules may be interchanged. It is understood that all spatial references, such as “superior,” “inferior,” “anterior,” “posterior,” “outer,” “inner,” and “perimeter” are for illustrative purposes only and can be varied within the scope of the disclosure.
