Once the pin abuts, the compression of the rod-shaped element proceeds against the restoring force of flexible section 105 .
- the flexural elasticity of the rod-shaped element i.e. with respect to the action of forces acting transversely to the rod axis, is determined only by the flexural elasticity of flexible section 105 .

- another flexible section with another sleeve with a symmetrical structure is provided adjacent to free end 104 as shown in FIG. 6 .
- a second flexible element can be used, or the flexible element shown can be longer and connected in its middle to rigid section 103 by any means, or the flexible element can be longer and guided through the rigid end section but not connected therein.
- the rod-shaped elements or sleeves according to the first and second embodiment need not have a circular cross-section, but can have different cross-sections such as for example, an oval or rectangular cross section.
- rigid sections 6 , 7 and sleeves 9 , 10 With non-circular cross-section, torsional motion can be limited.
- Flexible sections 4 , 5 and 105 need not be springs. If flexible sections 4 , 5 and 105 are springs, the sections need not have a helical shape but can be of any other shape.
- Flexible element 109 is shown as a rod-like flexible element.

Abstract
A rod-shaped element for use in spinal or trauma surgery, having a first section for connecting to a first bone anchoring element and a second section for connecting to a second bone anchoring element is described. The rod-shaped element also includes a first elastic flexible element that is capable of elastic deformation when a force acts on it transverse to the rod axis. The first section and the second section are capable of shifting relative to each other in the direction of the rod axis.
In a stabilization device for use in spinal or trauma surgery, the rod-shaped element allows for a controlled motion of the parts to be stabilized relative to each other so flexural motion is adjusted separately from the adjustment of the mobility in axial direction.

- The present invention claims the benefit of the filing date under 35 U.S.C. §119(e) of Provisional U.S. Patent Application Ser. No. 60/551,937, filed Mar. 9, 2004, which is hereby incorporated by reference. The present application also claims foreign priority benefits pursuant to 35 U.S.C. §119(a)-(d) for
German Patent Application 10 2004 011 685.7, filed Mar. 9, 2004 in Germany. - The present invention relates to a rod-like element for application in spinal or trauma surgery, and a stabilization device using such a rod-like element.
- European Patent EP 0 669 109 B1 describes a stabilization device for stabilizing neighboring thoracic vertebrae. The device comprises two pedicle screws and a strap that is fixed in the receiving part of the pedicle screws by a clamping screw. The device contains a support element in the form of a pressure-resistant support body that is mounted on the strap. This stabilization device is not torsion-resistant. Furthermore, the flexural elasticity and the tensile and compression force elasticity are coupled.
- U.S. Patent Published Application 2003/01 09 880 A1 describes a dynamic stabilization device for vertebrae. The device comprises a first and a second screw to be anchored in the vertebra, each of which has a receiving part for the insertion of a spring connecting the screws, and such a spring. The spring, a helical spring with closely neighboring turns, similar to a helical tension spring, is fixed in the receiving parts by means of clamping screws. This, however, poses the risk that the spring, due to its flexibility, escapes the pressure of the clamping screw, thus causing the connection between the spring and the bone screw to loosen. Moreover, the flexural elasticity and the elasticity with respect to tensile and compression forces are coupled in this device.

Patent Application DE 102 36 691 A1 describes a dynamic stabilization device for bones, in particular for vertebrae. This device comprises at least two bone anchoring elements and a rigid rod connecting the bone anchoring elements. A spring element is provided on the rod and arranged between the bone anchoring elements. One of the bone anchoring elements is connected to the rod so that it is capable of shifting in the direction of the rod axis, whereby the rod includes a stop for limiting the motion of the anchoring element that is capable of shifting. This stabilization device allows for a translational motion in the direction of the rod axis. In addition, the one anchoring element is capable of shifting relative to the rod and therefore providing for rotational motion of the anchoring element around the rod axis, but not for lateral flexion of the rod. - Therefore, there is a need for dynamic control of motion for the dynamic stabilization of pre-damaged intervertebral disks as well as artificial vertebral disks, in particular those with no inherent mechanism for limiting mobility. Particularly suited for this purpose are stabilization devices with an elastic element, such as the ones described above, which are inserted from the posterior side of the spine.
- It is therefore an object of the invention to provide a rod-shaped element for application in spinal or trauma surgery and a stabilization device with such a rod-shaped element which is suited for dynamic posterior stabilization or for dynamic guidance of motion in the presence of a pre-damaged intervertebral disk or in the use of artificial intervertebral disks, in which various degrees of freedom can be adjusted independently of each other.
- A rod-shaped element with a rod axis for use in spinal or trauma surgery is described comprising a first section for connecting to a first bone anchoring element; a second section for connecting to a second bone anchoring element and a first flexible element capable of elastic deformation when a forces acts on it transversely to the rod axis, so that the first and second section are capable of shifting or constantly moving relative to each other in the direction of the rod axis.
- A stabilization device is described having a first bone anchoring element, a second bone anchoring element and a rod-shaped element. The rod-shaped element comprises a first section for connecting to a first bone anchoring element; a second section for connecting to a second bone anchoring element and a first flexible element capable of elastic deformation when a forces acts on it transversely to the rod axis, so that the first and second section are capable of shifting relative to each other in the direction of the rod axis.
- In addition, a method of stabilizing bones or vertebrae is described comprising inserting a first bone anchoring element into a bone or vertebrae, inserting a second bone anchoring element into a second bone or vertebrae and inserting a rod-shaped element into said first and said second bone anchoring elements.
- The invention provides the advantage that the elasticity of the connection between two bone anchoring elements with respect to translational motion is decoupled from the flexural elasticity of the rod-shaped element connecting the bone anchoring elements. Connecting the bone anchoring elements by means of the rod-shaped element according to the invention also permits, as an option, free torsional motion around the rod axis, whereby the forces acting on the bone anchoring elements can thus, be reduced.

The width ofelastic rings 13 a, 13 b or 14 a, 14 b in axial direction as well the material of the elastic ring is selected so thatsleeve - The length of
rigid section 3 and ofrigid end sections sleeves - As seen in
FIG. 3 , the rod-shaped element described above is part of a stabilization device which comprises afirst pedicle screw 20, which is connected torigid section 3 and anchored in afirst vertebra 30. The stabilization device also includes asecond pedicle screw 21, which is firmly connected tosleeve 9 onrigid end section 6 and anchored in avertebra 31. Thesecond pedicle screw 21 is adjacent tovertebra 30. Athird pedicle screw 22, is firmly connected tosleeve 10 onrigid end section 7 and is anchored invertebra 32, adjacent tovertebra 30. - As is shown in
FIG. 3 a, the pedicle screws 20, 21, 22 preferably are polyaxial screws which comprise ascrew element 23 and a receivingpart 24 flexibly connected thereto, and apressure piece 25 acting onto the head ofscrew element 23 and afixation element 26 for fixing the rod-shaped element in receivingpart 24. In the example shown, the receiving part includes a channel for the insertion of the rod-shaped element and an internal screw that can be screwed into the receiving part to hold said rod-shaped element therein. Thus, the length ofrigid section 3 and the length ofsleeves internal screw 26 which presses onto the rod-shaped element on the various sections. - Although the pedicle screws are described as polyaxial screws, it will be appreciated by those skilled in the art that the pedicle screw can be any type of pedicle screw.
- In operation, the pedicle screws are inserted into the vertebrae first, and then the preassembled rod-shaped element, as shown in
FIGS. 1 and 2 , is placed into and fixed in the receivingparts 24. Thepedicle screw 20 of thevertebra 30 in the middle is thereby firmly connected torigid section 3 of the rod-shaped element, whereas the pedicle screws 21, 22 of the two neighboring vertebrae are firmly connected tosleeves - In the multiple-segment stabilization device shown in
FIG. 4 , thepedicle screw 20 connected to the middlerigid section 3 forms a fixed point for the device during any motion. Upon flexion of the spinal column,flexible sections 4, 5 are extended, causing the distance between pedicle screws 21 and 22 in an axial direction to increase. Simultaneously,sleeves screws - Upon flexion of the spinal column, the outer elastic rings 13 a, 14 b are initially deformed (illustrated by arrows A, A′ in
FIG. 4 ), whereas theflexible sections 4, 5 expand slightly (illustrated by arrows B, B′ inFIG. 4 ). With increasing flexion, the restoring force of the deformed outer elastic rings 13 a, 14 b increases more as compared to the restoring force offlexible sections 4, 5 ultimately leading toflexible sections 4, 5 having limited mobility, whereas outer elastic rings 13 a, 14 b have very little additional deformation. - The extension of the spinal column proceeds in an analogous manner against the restoring forces of inner
elastic rings 13 b, 14 a and the restoring force offlexible sections 4, 5. - In the embodiments shown, rotation of the sleeves around cylinder axis R is possible. Torsional forces around the cylinder axis are thereby prevented from acting onto the anchoring of the pedicle screws and loosening them.
- In a modification of the first embodiment, the rod-shaped element comprises only one flexible section and one section with a sleeve. The flexible section in this embodiment can be in the form of a spring. This element can be used between two neighboring vertebrae, one anchoring element being firmly connected to the rigid section and the second anchoring element being connected to the corresponding sleeve.
- In yet a further modification, the rod-shaped element does not have a rigid section. Rather, the rod-shaped element has two end sections with sleeves and a flexible section extending therebetween.
- In a further modification, the diameters of the flexible sections and of the rigid section as well as of the flexible sections between them are varied. In addition, the flexible sections can be made with different elasticities or spring constants. Furthermore, the rod-shaped element is not limited a symmetrical structure as shown in
FIGS. 1 to 4 , but the rod-shaped element can be nonsymmetrical for example, having sections of varying lengths. Additionally, instead of a securing screw, the rod-shaped element can have a different type of stop, e.g., a fitted ring or similar means. - The anchoring elements can be provided in the form of monoaxial screws or polyaxial screws or as hooks in a known fashion.
- In a second embodiment shown in
FIGS. 5 to 7 , the rod-shapedelement 100 comprises a hollowcylindrical rod 102 with a firstrigid section 103 having afree end 104, aflexible section 105 at one end of the firstrigid section 103. A secondrigid section 106 having afree end 121 is located adjacent toflexible section 105 and away from the firstrigid section 103. Theflexible section 105 shown in this embodiment is in the form of a spring. Any other flexible material can be used however to form such flexible section. Theflexible section 106, which in this embodiment is shown as a spring is formed by a helix-shaped recess in the wall of hollowcylindrical rod 102, similar to the first embodiment.Flexible section 105 andrigid section 103 have identical outer diameters, whereas the outer diameter of secondrigid section 106 is smaller, similar torigid end section 6 in the first embodiment. - As is seen from
FIGS. 6 and 7 ,rigid end section 106 comprisesoblong holes free end 121 and off-set from each other by 180°. Aninternal thread 108 can be found adjacent to a free end ofrigid section 103. - Hollow
cylindrical rod 102 also includes aflexible element 109, which is essentially rod-shaped and includes at its one end afirst connection section 110 with an outer thread which cooperates withinternal thread 108 ofrigid section 103.Flexible element 109 has asecond connection section 111 at its end opposite to thefirst connection section 110. Second connection section as seen inFIGS. 6 and 7 , comprises abore 112, that is continuous in the radial direction. The length offlexible element 109 is chosen so that whenflexible element 109 is attached to the end ofrigid section 103 and extended in the direction of the cylindrical axis to a pre-determined length the radial bore 112 coincides with oblong bore holes 107, 107′ and/or overlaps with them. - A
sleeve 117 having an inner diameter that is larger than the outer diameter ofrigid end section 106 is included in the device.Sleeve 117 can be inserted onto therigid end section 106 by a sliding motion. The outer diameter ofsleeve 117 corresponds to the outer diameter offlexible section 105 or ofrigid section 103. Thesleeve 117 is closed with acover face 118 on its end, away from the flexible section when in the assembled state. -
Sleeve 117 also includes twocircular apertures cover face 118. The diameters of the two circular apertures correspond to the diameter ofbore 112 offlexible element 109. - In the assembly of the device, a
pin 120 is guided throughapertures sleeve 117 and throughoblong holes rigid end section 106 of the rod, and throughbore 112 offlexible element 109. Thepin 120 resides in a fitting fashion inapertures bore 112. The length ofpin 120 is equal to or slightly smaller than the outer diameter ofsleeve 117. - The dimensions of
rigid section 106 of the rod, the position ofoblong holes sleeve 117, and the position ofapertures rigid section 106 is capable of sliding withinsleeve 117 over a distance that is defined by the length of the oblong hole which is limited bypin 120 abutting on the oblong hole. - The flexible element is preferably made from an elastic plastic material.
End sections - In operation,
rigid section 103 of the rod-shapedelement 100 is connected to an anchoring element anchored in the bone, for example with one of the polyaxial screws described above, whereas the other end of the rod-shaped element extending throughsleeve 117 is connected to a second bone anchoring element. Although described in this manner, any type of bone anchoring elements can be used. The extension of rod-shapedelement 100 from its relaxed state initially causessleeve 117 to shift relative torigid section 106, whereasflexible element 105 barely deforms due to its lower elasticity as compared toflexible element 109. Finally,pin 120 reaches the one end ofoblong holes sleeve 117 relative torigid section 106 so that the rod-shaped element can be further extended only against the spring force offlexible section 105. The compression of the rod-shaped element proceeds analogously to the stop ofpin 120 on the other end ofoblong holes flexible element 109 by shiftingsleeve 117 relative torigid section 106. Once the pin abuts, the compression of the rod-shaped element proceeds against the restoring force offlexible section 105. - The flexural elasticity of the rod-shaped element, i.e. with respect to the action of forces acting transversely to the rod axis, is determined only by the flexural elasticity of
flexible section 105. - In the second embodiment,
flexible element 109 assumes the function ofelastic rings 13 a, 13 b, 14 a, 14 b of the first embodiment, whereasflexible section 105 corresponds toflexible sections 4, 5. However, in contrast to the first embodiment, rotation around cylindrical axis R is not possible with the second embodiment, since rotation is prevented bypin 120 being guided inoblong holes - In a modification of the second embodiment, the rod-shaped element can be made from multiple segments, as described with the first embodiment. In this embodiment, another flexible section with another sleeve with a symmetrical structure is provided adjacent to
free end 104 as shown inFIG. 6 . In this embodiment, a second flexible element can be used, or the flexible element shown can be longer and connected in its middle torigid section 103 by any means, or the flexible element can be longer and guided through the rigid end section but not connected therein. - As before, with the other embodiments, it be appreciated by those of ordinary skill in the art that the individual sections can have different lengths and/or diameters.
- Moreover, the rod-shaped elements or sleeves according to the first and second embodiment need not have a circular cross-section, but can have different cross-sections such as for example, an oval or rectangular cross section. By making
rigid sections sleeves Flexible sections flexible sections -
Flexible element 109 is shown as a rod-like flexible element.Element 109 can, however be of any other shape provided that it is extensible in an elastic fashion. For example, it can be formed as a helical spring or as multiple strands of an elastomeric material. - The elements of the embodiments described above can be combined with each other.
- The embodiments described above and shown herein are illustrative and not restrictive. The scope of the invention is indicated by the claims, including all equivalents, rather than by the foregoing description and attached drawings.
