DETAILED DESCRIPTION [0017] As shown in FIGS. 1 and 2, the bone anchoring device comprises a bone anchoring element 1 in the form of a bone screw having a shank 2 with a bone thread, a tip 3 at one end and a spherical head 4 at the opposite end. A recess 5 for engagement with a screwing-in tool is provided at the side of the head 4 which is opposite to the shank 2. [0018] The bone anchoring device further includes a receiving part 6 having a first end 7 and a second end 8 opposite to the first end 7 and a longitudinal axis 9 intersecting the plane of the first end 7 and the second end 8. Coaxially with the longitudinal axis 9 a bore 10 is provided which extends from the first end 7 to a predetermined distance from the second end 8. At the second end 8 an opening 11 is provided the diameter of which is smaller than the diameter of the bore 10. A spherical section 12 is provided adjacent of the opening 10 which forms a seat for the spherical head 4. [0019] The receiving part 6 further has a U-shaped recess 13 which starts at the first end 7 and extends in the direction of the second end 8 to a predetermined distance from the second end 8. By means of the U-shaped recess 13, two free legs 14, 15 are formed extending towards the first end 7. Adjacent to the first end 7, the receiving portion 6 includes an internal thread 16 at the legs 14, 15. [0020] Further, there is provided a first pressure element 17 which has a cylindrical construction with an outer diameter which is only slightly smaller than the inner diameter of the bore 10 to allow the first pressure element 17 to be introduced into the bore 10 of the receiving part and to be moved in the axial direction. On its lower side facing towards the second end 8 the pressure element 17 includes a spherical recess 18 the radius of which corresponds to the radius of the spherical head 4 of the bone screw (see FIG. 3 a and 5). On the side opposite its lower side, the first pressure element 17 has a cylindrical recess 19 which extends transversely to the longitudinal axis 9. The lateral diameter of this recess is selected such that a rod 20 with a circular cross section which is to be received in the receiving part can be inserted into the recess 19 and guided laterally therein. The depth of the cylindrical recess 19 is selected such that in an assembled state when the rod 20 is inserted and pressed against the bottom of the U-shaped recess 13, the first pressure element 17 exerts a pressure on the head 5. Further, the depth of the cylindrical recess 19 is preferably about half of the diameter of the rod 20. [0021] As can be seen in FIGS. 1, 3 a and 5, the first pressure element 17 further has a coaxial bore 21 for guiding a screwing-in tool therethrough. On the surface of the first pressure element 17 which receives the rod 20, rib-like projections 22 are provided which extend in a direction transverse to the longitudinal axis L of the rod 20. A plurality of such projections 22 can be provided but a single projection is also sufficient. The projections 22 can have a structured shape which is able to press onto the smooth surface of the rod 20. As can be seen in FIG. 5, a cap 40 can be provided which fits into the coaxial bore 21 to close the coaxial bone 21 towards the cylindrical recess 19. [0022] As shown in FIGS. 4 a to 4 c, the bone anchoring device comprises a second pressure element 23 of a substantially cuboidal shape with a substantially square shaped first end 24 and a second end 25. The width of the second pressure element is such that the second pressure element can be inserted into the U-shaped recess 13 of the receiving part 6. On its opposing lateral sides, the second pressure element includes two projections 26 shaped like a segment of a cylinder which fit into the space limited by the internal thread 16 to slide along the internal thread 16 when the second pressure element 23 is inserted. [0023] The second pressure element 23 further includes a cylindrical recess 27 extending from the second end 25 in the direction towards the first end 24, the cylinder axis of which is perpendicular to that of the cylindrical projections 26. On the side of the second end 25, the cylindrical projections 26 include lower edges 26 a. The diameter of the cylindrical recess 27 corresponds to the diameter of the rod 20 and its depth to half or less than half of the diameter of the rod 20. Similar to the first pressure element 17, one or more rib-like projections 28 are provided extending circumferentially on the surface of the recess 27 between the opposite cylindrical projections 26. The projections 28 have a structured shape which allows them to press onto the surface of the rod 20. The second pressure element 23 further has a coaxial bore 29. [0024] The bone anchoring device further includes an inner screw 30 which can be screwed-in between the legs 14, 15. The inner screw 30 comprises a cylindrical projection 31 which can fit into the bore 29 of the second pressure element 23. The internal thread 16 and the cooperating thread of the inner screw 30 can have any known thread shape. A flat thread or a negative angle thread, however, can prevent splaying of the legs 14, 15. [0025] The receiving part 6 and the first pressure element 17 include corresponding crimp bores 32, 33 on opposite sides by means of which the screw 1, the receiving part 6 and the first pressure element 17 can be loosely preassembled such that the first pressure element 17 is oriented with its cylindrical recess 19 coaxial with the U-shaped recess 13 of the receiving part 6. [0026] The rod 20 can be made of an elastic material so that the rod 20 is partially or fully flexible. Preferably the rod 20 is made of a biocompatible plastic material, for example a polymer based on polyurethane or PEEK. The rod preferably has a smooth surface. The other parts of the bone anchoring device can be made of known biocompatible materials, such as stainless steel or titanium. [0027] In use, the bone screw 1 of the pre-assembled bone anchoring device is screwed into the bone. To provide a stabilization structure, at least two bone anchoring devices which shall be connected by a rod 20 are anchored into the bone. Thereafter, the cap 40 is inserted into the coaxial bore 21 of the first pressure element 17 and the rod 20 is inserted between the legs 14 and 15. Then, the second pressure element 23 is inserted such that the first and the second pressure elements 17 and 23 encompass the rod 20 from both sides. After adjusting the angular position of the bone screw 1, the inner screw 30 is screwed-in between the legs 14, 15 until it contacts the first end 24 of the second pressure element 23. When the inner screw 30 is tightened, the second pressure element 23 is moved towards the first pressure element 17 until the lower edges 26 a about onto the upper shoulders 17 a. The cross-section of the space encompassed by the first and second pressure elements 17 and 23 is slightly smaller than the cross-section of the rod 20. Thus, the material from which the rod 20 is made begins to flow (i.e., plastic flow) allowing the projections 22, 28 to press onto the rod 20 which provides a firm, form-fit connection between the rod 20 and the first and second pressure elements 17 and 23 without destroying the integral structure of the rod 20. The cap 40 prevents the material of the rod 20 from flowing into the coaxial bore 21. At the same time, the first pressure element 17 is pressed onto the head 4 by the second pressure element 23 to lock the screw head 4 by means of friction in its rotational position. Preferably the projections 22, 28 extend perpendicular to the longitudinal direction L of the rod 20 to secure the rod 20 with respect to movements of the rod 20 in a direction along the longitudinal axis L. [0028] As the locking of the rod 20 is achieved by pressing the projections 22, 28 onto the surface of the rod 20 without destroying the integral structure of the rod 20, secondary adjustments are possible. [0029] Modifications of the above described embodiment are possible. For example, the rib-like projections 22, 28 can be provided only at one of the two elements, either the first pressure element 17 or the second pressure element 23. Instead of having rib-like projections provided at the surface of the first and the second pressure elements 17, 23 it is possible that on one pressure element, projections are formed and at the other pressure element corresponding recesses are formed. This allows the material which is displaced when the projections press onto the surface of the rod to flow into the corresponding recesses to generate a form-fit connection. Projections and recesses can be provided on both pressure elements 12, 23. The volumes of projections and recesses can be similar or have the same size such that after the flow of material is completed, the volume of the rod 20 in the region of the connection with the receiving part 6 has approximately the same size as before. Hence, the contact surface of the two pressure elements 17, 23 represents a cage encompassing the rod 20 preventing an uncontrolled flowing-out of material and thus maintains the overall length of the rod 20. This keeps the rod 20 safe in place. Projections and/or recesses need not to have a rib-like structure but can have any shape to achieve the desired function of a form-fit locking. [0030] The rod 20 needs not to have a circular cross section. It can have an oval, rectangular or square cross section. The cap 40 can be omitted in case of rods 20 which have a sufficient stiffness. The elasticity of the rod 20 can vary. The rod 20 can be highly flexible or hardly flexible. The rod surface can be textured or structured. [0031] For the inner screw 30, all known modifications can be used. This includes also the use of an outer ring or nut. [0032] In the embodiment described, the bone anchoring element 1 is introduced from the top into the receiving part 6. However, the bone anchoring element 1 can also be introduced from the bottom of the receiving part 6 if the receiving part is constructed to allow such use. [0033] The head 4 of the bone anchoring element 1, the shank 2, and/or the tip 3 can be constructed as separate parts which can be connected. [0034] The invention is not limited to screws as bone anchoring elements but can be realized with bone hooks or any other bone anchoring element.
