Definitions
- the invention relates to a device for bone fixation, according to the preamble of claim 1.
- intramedullary nails are often inserted into the femur to fix the bone fragments.
- a bone plate is fixed to the proximal end of the intramedullary nail, by means of which the forces and moments acting on the hip joint head and the large trochanter can be transferred to the intramedullary nail.
- the invention seeks to remedy this.
- the invention has for its object to provide a device for bone fixation, in particular on the proximal femur, which on the one hand transmits an effective muscle force via the hip screw and the bone plate directly to the intramedullary nail and on the other hand forces acting on the femoral head not on the bone plate and thus directly transfers to the femoral shaft.
- the muscles, especially the lateral vastus, the minimus gluteaus, the piriformis and the maxims gluteaus and ligaments should not be distally affected by the expansion of the bone plate.
- the invention solves the problem with a device for bone fixation, which has the features of claim 1.
- the device for bone fixation essentially comprises an intramedullary intramedullary nail and a device intended for contact with the large trochanter.
- Bone plate located at the proximal end of the intramedullary nail, the intramedullary nail having at least one continuous transverse bore for receiving a hip screw in its proximal half facing the proximal rear end, and the bone plate ending proximally above this transverse bore.
- the length L of the bone plate measured parallel to the longitudinal axis of the intramedullary nail is preferably between 2 mm and 40 mm.
- the bone plate comprises a flap angled distally, the center of gravity of which, when projected into a cross-sectional area orthogonal to the longitudinal axis of the intramedullary nail, lies on a radius that unites with the projection of the bore axis of the proximal transverse bore into this cross-sectional area Includes angle ⁇ of between 0 ° and +100 °, preferably of between + 40 ° and + 50 °. These ranges for the angle ⁇ apply to the embodiment of the device according to the invention on the right femur.
- the angle ⁇ is between 0 ° and -100 ", preferably between -40 ° and -50 °.
- the intramedullary nail comprises in its distal half facing the tip a further continuous transverse bore for receiving a locking screw. This has the advantage that the proximal zone of the femur is relieved and the intramedullary nail takes over the load.
- transverse grooves are also possible, which are arranged transversely to the longitudinal axis of the intramedullary nail at its tip.
- the intramedullary nail and the bone plate are designed in one piece, so that the device to be implanted comprises fewer individual parts.
- the tab is designed such that it is spaced from the intramedullary nail and, viewed parallel to the longitudinal axis, is guided around the intramedullary nail at an angle ⁇ , the angle ⁇ being between 10 ° and 200 °, preferably between 20 ° and is 40 °.
- FIG. 1 shows a section through an embodiment of the device according to the invention on the proximal femur
- FIG. 3 shows a detail from the distal section of the intramedullary nail in an embodiment of the device according to the invention.
- 1 shows the intramedullary nail 1 inserted into the medullary cavity of a femur together with a bone plate 10 which is arranged on the large trochanter.
- the intramedullary nail 1 has a longitudinal axis 17, a proximal half 7 and a distal half 4 coaxially with this longitudinal axis 17.
- the bone plate 10 is angled distally and comprises a part arranged transversely to the longitudinal axis 17 of the intramedullary nail 1, where the bone plate 10 by means of a screw connection 16 is attached to the proximal rear end 3 of the intramedullary nail 1, and a tab 22, which is provided with perforations 11 and extends against the distal tip 2 of the intramedullary nail 1.
- the intramedullary nail 1 comprises a proximal transverse bore 6 and a second transverse bore 8 in its proximal half 7 , both of which serve to accommodate hip screws 30; 31.
- the transverse bores 6; 8 penetrate the intramedullary nail 1 transversely to the longitudinal axis 17.
- the bone plate 10 ends proximally above the proximal transverse bore 6.
- a transverse bore which is likewise arranged transversely to the longitudinal axis 17 of the intramedullary nail 1 5 attached.
- a locking screw 20 is inserted into this distal transverse bore 5 and screwed to the femur.
- the bone plate 10 comprises a part arranged transversely to the longitudinal axis 17 of the intramedullary nail 1 and a distally angled tab 22 with two tongues 23; 24 aligned against the distal tip 2 of the intramedullary nail 1.
- a cross-sectional area 19 orthogonal to the longitudinal axis 17 of the intramedullary nail 1 the projection of the center of gravity of the tab 22 lies on a radius 21, which includes an angle ⁇ of 45 ° with respect to the projection of the bore axis 18 of the proximal transverse bore 6 in this cross-sectional area 19.
- the tab 22 When viewed parallel to the longitudinal axis 17 of the intramedullary nail 1, the tab 22 wraps around the intramedullary nail 1 at an angle which lies in a range from 155 ° to 165 °.
- the tongues 23; 24 end proximally from the proximal transverse bore 6.
- the bone plate 10 in its part which is transverse to the longitudinal axis 17 of the intramedullary nail 1 comprises a circular bore 13 which is arranged coaxially to the longitudinal axis 17 and by means of which the bone plate 10 via a corresponding, on the proximal rear end 3 of the intramedullary nail 1 attached circular cylindrical elevation 9 is slidable.
- Bone plate 10 On its surface facing the proximal rear end 3 of the intramedullary nail 1, the surface comprises Bone plate 10 has a cam 12 which can be countersunk into a corresponding depression 14 made at the proximal rear end 3 of the intramedullary nail 1. As a result, the bone plate 10 can be brought into a defined position relative to the intramedullary nail 1 and secured against rotation about the longitudinal axis 17 of the intramedullary nail 1.
- the bone plate 1 At the proximal rear end 3 of the intramedullary nail 1, the bone plate 1 is fixed by means of a nut 40, the internal thread 41 of which can be screwed via an external thread 15 attached to the circular cylindrical elevation 9 at the rear end 3 of the intramedullary nail 1.
- FIG. 3 shows a detail from the distal half 4 of the intramedullary nail 1, the distal half 4 only differing from the embodiment of the intramedullary nail 1 shown in FIG. 1 in that, instead of the distal transverse bore 5, two parallel transverse grooves 28 are provided.
- the transverse grooves 28 are arranged transversely to the longitudinal axis 17 of the intramedullary nail 1, run parallel to a plane spanned by the longitudinal axis 17 of the intramedullary nail 1 and the bore axes 18; 25 and serve to partially accommodate locking screws 20 (FIG. 1).
