Definitions
- the present invention relates to a device for the dynamic stabilization of bones or bone fragments, in particular vertebral bodies, with at least one longitudinal support that can be fixed to the vertebral bodies.
- the main indications for a dynamic fixation are an age and / or disease-related deterioration (degeneration) of the integrity of the spinal column structures, inflammation and / or injuries in the area of the intervertebral disc, the ligamentous apparatus, the facet joints and / or the subchondral bone.
- Posterior dynamic fixation systems have the function of modifying the movement pattern in the affected spine segment in such a way that the pain caused by chemical irritation (nucleus material in contact with nerve structures) and / or mechanical irritation (hypermobility) disappears and the metabolism of the structures is retained or restored becomes.
- the side members are advantageously made from a biocompatible high-performance plastic. Due to the much lower modulus of elasticity of the high-performance plastics compared to titanium and steel, the side members can be made relatively thick compared to the commonly used metals steel and titanium without losing flexibility, which has a positive effect on thrust and buckling resistance :
- EP 0 690 701 B1 Another embodiment of a dynamic fixation system is proposed in EP 0 690 701 B1.
- This latter system comprises a connecting rod, the ends of which can be fixed to two adjacent vertebral bodies and which has a curved central section, so that it is within certain limits is resilient. Otherwise, the shape of the connecting rod is unchangeable.
- WO 01/45576 A1 also proposes a dynamic stabilization system which comprises a longitudinal beam which has two metallic end sections which can be fixed in complementary receiving openings within the head of two adjacent pedicle screws. Arranged between the two end sections is an articulated body which is elastically resilient in the longitudinal direction and which preferably consists of elastically resilient material. The two end sections of the side member are rigid. In addition to this joint body, the arrangement of an elastic band between two pedicle screws is proposed, which extends parallel to the elastic joint body.
- the longitudinal direction of the joint body is specified by the manufacturer, i.e. unchangeable.
- the longitudinal member is designed as a spring element, for example in the form of a meandering curved leaf spring.
- the longitudinal member also comprises a spring element which maintains its shape specified by the manufacturer.
- the aim of the present invention to provide a device for the dynamic stabilization of bones or bone fragments, in particular the vertebral bodies, with at least one longitudinal beam that can be fixed to the vertebral bodies and that can be easily adapted to the most varied of situations for the implantation, without losing the dynamics.
- the at least one longitudinal beam which is fixed, for example, between two adjacent pedicle screws, is designed in such a way that it is applied by applying a predetermined bending force is plastically deformable from a first shape state "A” into a second alternative shape state "ET, the bending force required for this being significantly greater than the peak forces occurring in vivo.
- the longitudinal beam should be elastically bendable, namely within the due to the mechanical interplay between the fixation system and the spinal segment, which define a so-called "elastic flex area”.
- the device according to the invention is in principle also suitable for an anterior implantation if it is important to shift the pivot point of the affected spinal column segment anteriorly.
- a particularly advantageous embodiment of the device according to the invention solves the problem of bending longitudinal members made of a biocompatible high-performance plastic by inserting a metal rod centrally into the longitudinal members.
- the metal rod must be so thin that its critical bending angle is greater than or equal to the maximum bending angle of the stabilized vertebra that occurs in conjunction with the dynamic fixation system, and on the other hand it is so thick that the side member remains dimensionally stable after bending in situ.
- the central metal rod In order to set a predetermined bending elasticity, it is conceivable for the central metal rod to be sheathed in several layers, the individual layers being distinguished by very special mutually coordinated elastic moduli.
- DE 93 08 770 Ul describes a plastic rod with a metal core.
- This plastic rod serves as a test rod or template in order to optimally adapt the shape of the side members to the position and orientation of the pedicle screws.
- the test rod must be able to be molded on by hand in situ in the patient.
- the test stick consists of a soft plastic (e.g. silicone) and a plastically easily deformable metal stick (e.g. pure aluminum). If the test rod has the same outer diameter as the side member, the sample rod reproduces exactly the shape that is necessary to be able to insert the side member into the pedicle screws without tension.
- the present invention differs from the teaching according to DE 93 08 770 Ul due to the condition defined above that
- the at least one longitudinal beam is plastically deformable by applying a predetermined bending force from a first shape state "A” to a second alternative shape state "B", the bending force required for this being significantly greater than the peak forces occurring in vivo, and
- the at least one longitudinal beam can, however, be elastically bent within the respectively stable shape states, specifically within the limits given by the mechanical interaction between the fixation system and the spinal column segment, which define a so-called “elastic flex area”.
- the elasticity in the bend of the longitudinal beam used according to the invention is preferably defined such that it can be deflected elastically by clamping at one end in a dimensionally stable state by an angle of 5 ° to 12 °, in particular approximately 8 °.
- the at least one side member In order to initiate the above-mentioned pain relief and healing processes, the at least one side member must be designed in such a way that it is as stiff as possible in relation to compression and thrust forces occurring in vivo and that the construction consisting of side member and anchoring means is essentially torsionally rigid.
- the longitudinal beam according to the invention can be any longitudinal beam according to the invention.
- a) be flat or strip-shaped, or
- b) have a rotationally symmetrical, circular, polygon-like or elliptical cross-section, the cross-section remaining constant in the longitudinal direction of the longitudinal member over the entire length, varying according to a mathematically describable law and / or changing abruptly.
- the dynamic fixation system can be converted at any time into a fusing fixation system by the dynamic longitudinal member being replaced by a metallic and accordingly rigid longitudinal member is replaced without having to replace the pedicle screws, and vice versa.
- the aim is to have a dynamic stabilization system ready, based on the following basic considerations:
- the main indications for a dynamic system are diseases, inflammations and / or injuries in the area of the intervertebral disc, the ligamentous apparatus, the facet joints and / or the subchondral bone.
- it is important to change the stress pattern in the affected area so that the pathological condition does not worsen at least.
- a cure would be ideal, but this is hardly possible at least in the case of degenerative diseases.
- the goal of the dynamic system to be developed is not only to freeze the pathological condition or even bring about healing, but together to form a unit supporting the metabolism of the structures with the structures concerned.
- a posterior shift of the fulcrum to the area of the posterior facet joints can have the following effects, depending on the pathology:
- Inflammation can occur, among other things, in the area where granulation tissue and / or nerve endings that grow in from the outside also hit nucleus material that presses through cracks in the annulus (physiological Pain) This inflammatory process is constantly promoted by the constant flow of nucleus material, but in theory it does not necessarily need one Inflammation to cause pain; the mechanical pressure of a fluid pocket on afferent nerve endings alone can cause pain. Appropriate stabilization can stop the inflammatory process and even trigger healing. The following considerations result:
- the posterior displacement of the pivot point of the spinal segment drastically reduces its range of motion in flexion and extension and the axial force acting on the intervertebral disc is evenly distributed over the entire intervertebral disc.
- the nucleus material is no longer tumbled back and forth, ie there is less nucleus material which stimulates the inflammatory process and is pressed against the focus of inflammation by cracks in the posterior annulus. This creates the conditions for the inflammation to heal and can use a repair process.
- a disc hernia is a connection between the nucleus and the area surrounding the annulus. This means that nucleus material can constantly flow through through annular cracks. With a nucleotomy, the leaked material as well as material is removed from the nucleus, the latter in order to avoid secondary disc hernias. This surgically enlarges the posterior annulus lesion.
- a posterior displacement of the pivot point of the spinal column reduces the flow of nucleus material.
- the disc hernia can no longer increase and material that escapes if it has not already been surgically removed is encapsulated and resorbed by the body.
- a repair process can take place on the posterior annulus.
- a dynamic system with a primary disc hernia has, at least theoretically, the advantage that the surgical intervention can be designed to be minimal (it is not an opening of the epidural space and no additional damage to the Annulus required). This creates optimal conditions for healing and restoration of the function of the intervertebral disc.
- the pain in the posterior annulus can be caused by delamination of the annulus. Delamination of the posterior annulus occurs when the nucleus is dehydrated and the intervertebral disc has collapsed accordingly.
- the posterior displacement of the fulcrum in the area behind the posterior facet joints reduces the pressure in the area of the posterior annulus, which prevents further delamination of the posterior annulus. This creates the prerequisites for healing / discoloration of the annulus, provided, of course, that the annulus has a corresponding healing potential.
- MRI magnetic resonance imaging
- a sclerotic change in the bony cover plate can also be ascertained, which indicates a bottleneck or stop in the nutrition of the intervertebral disc.
- a sclerotic change in the cover plate is hardly reversible.
- the degenerative "demise" of the intervertebral disc is pre-programmed.
- the first-mentioned inflammation can be remedied by suitable measures, provided that the corresponding tissue is not permanently damaged.
- the increased pressure in the subchondrial bone due to the backlog can lead to mechanical irritation of the afferent nerve endings (mechanical pain). Measures that reduce the pressure in the subchondral area can at least reduce the mechanical pain, if not make it disappear. However, the cause of the problem can only be found with difficulty in the latter case.
- the posterior displacement of the fulcrum in the area behind the posterior facet joints not only relieves the pressure on the intervertebral disc, but also on the subchondrial bone underneath. With a suitable dynamic fixation, the prerequisites for pain relief and in the case of inflammation in the area of the subchondrial bone are even created for healing.
- Pain (sciatica, etc.) only arises when inflammatory nucleus material emerges through cracks in the posterior annulus and presses on the nerve roots.
- a posterior displacement of the pivot point of the spinal column segment reduces the flow of the stimulating inflammatory process Nuclear material. This creates the conditions for the inflammation to heal and for a certain repair process to start in the posterior annulus. It is even conceivable to clear a disc hernia if no new nucleus material flows in.
- the cranial vertebral body of the affected segment and the associated intervertebral disc are usually affected. Thanks to good blood circulation, the bony healing of the vertebral body is no longer a problem with the fixation techniques described today and at the beginning. In contrast to the vertebral body, healing of the intervertebral disc is based on other laws due to the lack of blood circulation and regrets means longer. A switch from a stiff posterior fixation to a flexible posterior fixation after approximately 6 months relieves the pressure on the intervertebral disc and allows certain movement components.
- the prerequisites for healing of the intervertebral disc are created, provided that the supply of the intervertebral disc from the subchondral area of the adjacent vertebrae is not disturbed (e.g. by callus formation in the area of the subchondral bone).
- the posterior dynamic displacement of the pivot point of the relevant spinal segment in a posterior dynamic system relieves the traumatized intervertebral disc and also allows an axial deformation that is important for the nutrition of the intervertebral disc.
- the system according to the invention should also be distinguished, on the one hand, by an extremely elegant construction and surgical technique, on the one hand, by the advantages of a dynamic system and, on the other hand, by the possibility of optimally determining the posterior pivot point of a predetermined spinal segment.
- the bone anchoring means for example pedicle screws
- the posterior pivot point can be set individually.
- the simplest embodiment of these considerations is to provide pedicle screws with screw heads of different heights, in which the longitudinal beam receiving slots are formed.
- An alternative embodiment comprises screw heads which are axially variable with respect to the pedicle screw shaft, for example the screw heads being screwed onto the screw shafts and being individually highly fixable by means of counter screws.
- pedicle screws with screw heads that can be plugged onto and / or rusted onto the threaded shaft and have longitudinal member receiving openings of different heights. It should be borne in mind that after placing a pedicle screw, the surgeon will not subsequently lower or raise it (with the risk of loosening) to place the longitudinal beam at a predetermined distance from the vertebral body. He only needs to replace the screw head or adjust the height.
- Fig. 1 A vertebral segment comprising four vertebral bodies with a posterior
- FIG. 2 shows the arrangement according to FIG. 1 in a side view along line 2-2 in FIG. 1;
- Fig. 3 shows a longitudinal beam designed according to the invention in the form of a round bar, partially cut, partially in a perspective view, and on an enlarged scale.
- FIGS. 1 and 2 A part of a spine is shown in FIGS. 1 and 2, the individual vertebral bodies being identified by the reference letter “ ⁇ ”. The spine is marked with the reference letter "S”.
- the individual vertebral bodies “V” are stabilized posteriorly, specifically for this purpose are screwed into four vertebral bodies “V” by posterior pedicle screws.
- the screw heads each have receiving openings or slots for receiving a rod-shaped longitudinal member 11.
- the longitudinal member 11, as can also be seen in particular in FIG. 3, is designed in the form of a round rod and is clamped in the heads of the pedicle screws 10. In this way, a spinal column segment with four vertebral bodies “V” can be stabilized.
- the longitudinal beam (s) 11 are designed in such a way that by applying a predetermined bending force from a first stable shape state to a second alternative stable shape state according to FIGS. 1 and 2. However, within this implantation state, the longitudinal beams 11 should be elastically bendable, within predetermined limits, as shown in the introduction. Dynamic stabilization of a predetermined spinal column segment is thus achieved with all the advantages as stated above.
- the longitudinal beam 11 is provided with a core 12 made of metal, in particular titanium or titanium alloy, which is encased in a plastic 13 that is compatible with humans.
- the plastic deformability of the longitudinal beam 11 is primarily ensured by the metallic core 12, while the elasticity in the deformed state is primarily due to the plastic jacket 13.
- the above-mentioned bending elasticity of the longitudinal beam 11 is indicated in FIG. 2 by a double arrow 14. It is dimensioned such that when the longitudinal beam 11 is clamped in at one end, it can be elastically deflected by an angle of 5 ° to 12 °, in particular approximately 8 °, within a dimensionally stable state (double arrow 14).
- the device described can comprise longitudinal beam connecting means, by means of which at least two longitudinal beam sections can be connected to one another.
- the longitudinal beam connecting means can, for example, have two opposite longitudinal beam receiving openings or slots, into each of which a longitudinal beam end section can be inserted and fixed by means of a clamping screw or the like.
- the longitudinal beam connecting means can either be rigid or preferably also flexible. They allow segmental implantation of longitudinal members and extremely individual stabilization of a spine section.
- FIGS. 1 and 2 It can also be seen from FIGS. 1 and 2 that the spinal column section is always stabilized by means of the device according to the invention in such a way that there is flexibility only in the context of flexion and extension. This considerably reduces pressure on the cover plate and intervertebral disc, without losing the axial deformation of the intervertebral disc that is important for feeding the intervertebral disc.
- the longitudinal member described must of course also be designed so that it is with a predetermined force that is above anatomical or in vivo peak forces, permanently deformed. This deformation takes place outside of the implantation, and should preferably be possible without separate auxiliary devices. The deformation is carried out "on site” by the surgeon.
- the longitudinal member is to be stable with respect to the anatomically usual thrust forces, i.e. to be adamant.
- the side member it is very often desirable for the side member to be torsionally rigid to ensure that the affected vertebral body segment i.w. usually only extends approximately horizontally around a pivot point displaced posteriorly.
- the longitudinal beam can be designed in the form of a flat band or strip. In the embodiment described, round rod-like longitudinal members are implanted.
- the angular range mentioned at the outset relates to a length of the longitudinal beam 11 which corresponds to the distance between two adjacent vertebral bodies, that is to say a distance of approximately 2-6 cm, in particular approximately 4-5 cm.
- the width and / or height of the flat-band-like core can vary continuously or in steps over the length of the longitudinal beam, at least over a longitudinal section thereof.
- the diameter of the core continuously increases or decreases, at least in sections, so that the core takes the form of a wedge or cone.
- the transitions in the area of a step are preferably rounded in order to reduce or completely avoid step-related stresses.
