The head is formed as a securing means for at least one support element (3). Each support element consists of a piece of a cable-like band (31) and a cylindrical support body (30) with an axial lumen (31″containing the band. The band is securable outside end surfaces (32) of the support body in the head. The head is formed with a contact surface (23) via which a pressure stress can be exerted on the support body in the band direction, and indeed using the band and in cooperation with a further pedicle screw. A part (20) of the head (2), which is firmly connected to the shaft (10) at the one end of the latter, contains a base groove (21) which is oriented transversally to the shaft and into which the part of the band (31) to be secured or a connecting piece (292) which contains the band can be introduced during the securing of the support element (3) by means of a translatory movement in the direction of the shaft and fixed there.

[0019] A lumbar vertebra 9 in accordance with FIG. 1 consists of a vertebral hole 90, a vertebral body 91 and a vertebral arch 92 which comprises two pedicles 93, two transverse processes 94, a spine 95 of a vertebra and articular processes 96. The positions of two pedicle screws 1 in the implanted state are indicated in chain-dotted lines. In these positions the heads 2 of the pedicle screws 1 are located directly at the outer side of the pedicles 93 between the transverse processes 94 and the articular processes 96. FIG. 2 shows two pedicle screws 1, which are provided for two adjacent vertebrae 9 and between the heads 2 of which, which are formed as rings, an intervertebral support element 3 is arranged. Shafts 10 of the pedicle screws 1 are screwed in into the vertebrae 9. The heads 2 have notches 4 laterally which are required for the implanting and orientation of the pedicle screws 1 by means of an instrument. The support element 3 consists of a piece of a cable-like band 31 and a cylindrical support body 30 in which the band 31 is contained in an axial lumen 31′. The band 31 is secured outside of end surfaces 32 of the support body 30 in each case in the heads 2 of the pedicle screws 1 with a setting screw 22. The heads 2 are provided with planar contact surfaces 23 via which a pressure stress can be exerted on the support body 30 in the band direction via their end surfaces 32, with the tension force required for this being produced using the band 31 and in cooperation with the pedicle screw 1 of the adjacent vertebra 9. [0020] An outline drawing with two adjacent lumbar vertebrae 9 is shown in FIG. 3. The positions of two implanted support elements 3 are indicated. [0021] The pedicle screw 1 in accordance with the invention differs from the known pedicle screw through a specially formed head 2. The support element 3 can be laid in into the latter by means of a translational movement in the direction of the shaft 2, so that the support element 3 can be fixed in the head without a drawing in of the band 31 into an eye-like securing means being required. [0022] A first embodiment of the head 2 of a pedicle screw 1 in accordance with the invention is illustrated in FIG. 4 together with a support element 3. A part 20 of the head 2 which comprises two lugs 20 a and 20 b and which is firmly connected to the shaft 10 contains a base groove 21 which is oriented transversely to the shaft 10 and a thread 24. A part of the band 31 which is to be secured is inserted into the base groove 21 during the securing of the support element 3 and is fixed with a screw 22. The base groove 21 has a shape which corresponds to the shape of the band in such a manner that the base groove is formed complementarily in the insertion region. An edge region 21′ of the base groove 21 can�in order to prevent a damage to the inserted band 31�be formed in such a manner that the base groove 21 widens in the direction towards the contact surface 23. [0023] The embodiment of FIG. 4 is a first example of a pedicle screw in accordance with the invention, in which the lugs 20 a, 20 b, which form flanks of the base groove 21, have depressions 24 on their inner sides into which a securing part, namely the screw 22, can be firmly anchored by means of a form lock. After the production of the form lock the lugs 20 a, 20 b are advantageously elastically spread apart somewhat by the securing part 22, so that the position of the latter is additionally fixed as a result of an increased adhesive friction and thus of a force lock. [0024] A second example is shown in FIG. 5, in which the lugs 20 a, 20 b have groove-like depressions 24 a on their inner sides. A T-shaped groovestone 25 with lateral ribs 25 a is pushed in between the grooves 24 a after the insertion of the band 31�cf. FIG. 5�and for fixing the band 31 a setting screw 22�cf. FIG. 5�is screwed into a bore in the groove-stone 25 with inner thread 250. [0025]FIGS. 6 and 7 show in each case a head 2 in which a disc-shaped part 26 is arranged between the support element 3 and the head 2. The head 2 in FIG. 6 comprises a core part 20 and at least one disc-shaped part 26 which forms the contact surface 23 to the cylindrical support body 30 of the support element 3 on the one side and which forms a contact surface 261 to the core part 20 on the other side. The surface of the core part 20 is made spherical. The contact surface 261 to the core part 20 of the disc-shaped part 26 is made in the shape of a spherical section corresponding to the shape of the core part 20. The disc-shaped part 26 is applied together with the support body 30 to the band 31, with the band 31 being drawn into the bore 260. This drawing in of the band 31 is carried out prior to the implanting of the support element 3 outside the body of the patient to be operated on. [0026] The head 2 in FIG. 7 comprises a core part 20 which has at each end of the groove 21 an elevation 262 which is formed to fit complementarily to a groove 263 of the disc-shaped part 26 (ridge-groove form lock). The groove 263 can be pushed onto the elevation 262 in the direction of the�shaft 10. As was already the case in the example of FIG. 6, the part 26 is applied to the band 31 prior to the implanting. [0027]FIG. 8 shows a head 2 with a core part 20 and with a connector 27 which is a sleeve-like part and the inner space of which has a square profile which is formed by planar surfaces. The core part 20 is tightly enclosed by the connector 27, so that a spreading open of the lugs 20 a, 20 b during the screwing in of a screw 22 (see FIG. 10) into the thread 24 is prevented. [0028]FIG. 9 shows a variant 27′ of the connector 27 of FIG. 8. This connector 27′ is made longer in the direction of the groove 21 or of the bore 270 and contains a bore with inner thread 272. The band 31 can additionally be fixed below the threaded bore 272 with a second screw 22. [0029]FIG. 10 shows a head 2 with a sleeve part 28 and with a core part 20 which is firmly connected to the one end of the shaft 10. The screw-cap part 28 is displaceable along the entire shaft 10 up to the named shaft end. In this the thread 24 comes to lie over the groove 21 so that the screw for the securing of the band 31 can be screwed into the thread 24. [0030]FIG. 11 shows a further embodiment of the head 2 with a connector 29. The band 31 can be secured in the connector 29 in a bore 293. During the operation the connector 29, which contains the band 31, is placed onto the core part 20 of the head 2, with a connecting piece 292 of the connector 29, which has a prismatic shape, being laid in into the corresponding complementarily shaped groove 21. The securing between the connector 29 and the core part 20 can be produced for example with two screws. The non-illustrated screws are inserted through bores 291 a of the connector 29 and are screwed tight in threaded bores 291 b of the core part 20. [0031] The embodiments in accordance with FIGS. 6 and 10 permit a so-called �polyaxiality� in the fixing of the support body 30 at the pedicle screws 1. The �polyaxiality� relates to the axis of the shaft 2; in all other body 30, which is given by the axis of their lumens 31′. The term �polyaxiality� is intended to mean that the angle between the two axis directions is not fixed in advance, but can vary within a certain angular range. This will be explained for the embodiment in accordance with FIG. 10 in more detail with reference to FIG. 12: FIG. 12 shows a cross-sectional illustration of the pedicle screw head 20 with the sleeve part 28, the inner surface 280 of which is a partial region of a spherical surface. The head 20 is made correspondingly spherical, so that it can be laid in into the sleeve part 28 in different positions. The axis of the shaft 10 has a main direction z perpendicular to the direction x of the support body 30 (x is perpendicular to the plane of the drawing). The shaft axis can deviate with respect to this main direction z by an angle (φ. This angle φ has a maximum value φmax which amounts to 10� or even more, but which is less than 15�. The angle φ can vary in the region of a cone about the main direction z, with the half opening angle of this cone amounting to φmax. Corresponding remarks also hold for the embodiment in accordance with FIG. 6. The system for the vertebral support which can be produced with the pedicle screws in accordance with FIGS. 6 and 10 is easier to implant thanks to the �polyaxiality�. [0032] Longitudinal components comprising support elements are anchored in vertebrae with pedicle screws, with a dynamic stabilizing of the vertebrae being producible thanks to an elastic yielding of the support elements. The pedicle screws in accordance with the invention permit a head feeding of the longitudinal components. In the head feeding the longitudinal components are laid in into the heads of the pedicle screws in that merely a translational movement in the direction of the shaft in that merely a translational movement in the direction of the shaft need be carried out. Through a simple insertion of this kind the operation technique is obviously substantially simplified with respect to the older treatment methods, in which the bands of the support elements must be drawn in into the screw heads, which are formed in ring shape.
