Definitions
- the invention relates to a connecting element according to the preamble of patent claim 1.
- Such connecting elements are suitable for bridging a plurality of bone anchoring elements implanted in the bone, in particular in the area of the spine, i.e. for bridging pedicle screws. They have been known for a long time, but they are always relatively rigid longitudinal beams, which are adapted to the anatomical or clinical course with special measures, i.e. must be bent.
- a connecting element which does not consist of a single longitudinal beam, but consists of a large number of elastic wires lying loosely next to one another (bundle of rods).
- a disadvantage of this known device is the risk that the individual wires can cross each other, which leads to unstable connections.
- the invention seeks to remedy this.
- the invention has for its object to provide a connecting element which has a greater elasticity during implantation, so that it can be deformed reversibly and which can be stiffened in the bone anchoring elements (e.g. pedicle screws) after fixation.
- the invention solves this problem with a connecting element which has the features of claim 1.
- the connecting element can be implanted in a minimally invasive manner through a curved tube and then by being fixed with the
- Bone anchoring elements can stiffen. Compared to the known rod bundle mentioned above, there is the advantage that there is always a precisely defined one External shape is present, both in the resting state and in the radially tensioned state, ie after fixation in the bone anchoring elements.
- the connecting element has a cavity running in the direction of the longitudinal axis, as a result of which a jacket is defined.
- a jacket is defined.
- the slotted jacket has the same outside diameter in both the clamped and unclamped state. In the case of a slotted rod with a full cross section, the material losses due to the slitting must be compensated for by reducing the outside diameter.
- An additional advantage is that the rod cross-section is divided into two elements, whereby the bending stiffness of the pipe portion can be reduced.
- the slots preferably penetrate the jacket radially and the cavity expediently extends continuously from the rear end to the front end, so that the connecting element is tubular.
- the slots are arranged in such a way that the jacket remains connected.
- the ends of the slots lie within the connecting element.
- the ends of the slots on one side break through the rear end and / or the front end. In this embodiment there is a higher bending elasticity.
- the connecting element is bent, a longitudinal displacement of the outer shell elements relative to the inner elements can take place.
- the connecting element can be made from the known metallic materials or from plastic.
- the connecting element has a round outer cross section. This results in uniform mechanical properties of the connecting element, regardless of the rotational orientation of the connecting element.
- the connecting element has a polygonal outer cross section.
- a connecting element with a polygonal cross section allows a defined orientation of the connecting element in connection with pedicle screws, the rod receptacle of which is also polygonal.
- the mechanical properties, e.g. the stiffness can be predefined differently depending on the direction of loading, which is advantageous.
- the slots can have a maximum width of 1.0 mm, preferably a maximum of 0.6 mm.
- the connecting element (1) has a uniform mechanical strength and rigidity over its entire length.
- the uniform rigidity of the connecting element over its entire length leads to a distribution of the applied bending moment over the entire length of the connecting element and thereby prevents stress concentrations at the transitions.
- the slots can - at least partially - be filled with a softer material than the connecting element, preferably with PEEK, which prevents the undesired ingrowth of tissues.
- the slots are arranged offset, as seen radially to the longitudinal axis. This enables uniform bending rigidity and elasticity in different directions.
- a plurality of slots — viewed axially — are arranged one behind the other, so that there are a plurality of radially offset groups of such slots arranged axially one behind the other.
- the subdivision of the slots into several slots, seen in the axial direction arranged one behind the other is particularly suitable for long connecting elements. The torsional stiffness and the bending stiffness can thereby be increased and / or adjusted.
- the individual slots of a group appear axially offset from the slots of the radially adjacent groups. This gives the advantage of uniform mechanical strength and rigidity.
- the connecting element additionally has a central rod inserted into the cavity.
- the central rod can be made of metal, preferably titanium, a titanium alloy or steel.

- the surgical technique for the connecting element 1 according to the invention is briefly described below:
- the connecting element 1 with longitudinal slits 5 allows a mihimally invasive surgical technique for the posterior spine supply.
- the aim of this minimally invasive surgical technique is to secure the implant anchoring elements 20 such as screws, hooks, jaws, etc. as well as to implant the side member with minimal access.
- the flexibility of the side member enables it to be implanted using a curved implantation aid, e.g. a curved pipe.
- the surgical access is thus reduced to the dimensions of the tube.
- the implant anchoring elements 20, which are elongated via manipulators, serve to manipulate the individual vertebral bodies during the insertion of the slotted connecting element 1, such as the correction of the spine with the connecting element 1 lying down. After the desired correction has been achieved, the connecting element 1 is fixed in the individual implant anchoring elements 20, as a result of which a stiffening of the slotted connecting element 1 is achieved and sufficient rigidity of the fracture treatment is achieved.

Abstract
L'élément de jonction (1) a la forme d'une barre présentant un axe longitudinal (2), une extrémité arrière (6) et une extrémité avant (7) et sert au pontage de plusieurs éléments d'ancrage osseux (12) implantés dans des os. L'élément de jonction (1) présente au moins une rainure longitudinale (5). Il présente ainsi pendant l'implantation une plus grande élasticité, de sorte qu'il peut être déformé de façon réversible, mais devient toutefois rigide une fois fixé dans lesdits éléments d'ancrage (par exemple, vis pédiculaires).
