Definitions
- the invention relates to fracture bone screws, preferably with a countersunk head for the fixation of bone fractures, the screw head which can be screwed in with a tool being additionally provided with a plurality of bores for attaching fixation wires or threads.
- Bone screws are known for the fixation of bone fractures, which are either provided with a cortex or cancellous thread. These screws are standardized according to the AO working group for osteosynthesis, as described and shown, for example, in the SYNTHES catalog (2/94). Most of them are provided with a round countersunk head, which has a hexagon socket for screwing in. Such screws are also known as special screws in the longitudinal direction with a through-hole for inserting a wire, for example from the Mecron catalog.
- German utility model G 86 10 715.1 discloses a bone screw which has a hole in the screw head, in the area of the screw-in hexagon, which leads to the center of the screw. After screwing in, this hole is used to insert an anti-twist device in the form of a safety wire. Cerclage wires or threads cannot be provided in the head of the screw before screwing in.
- EP 0582 857 discloses a spinal fixation element that has a bore in the head part for the introduction of a wire or thread-like tensioning device. Here too, only a single transverse bore is provided, and several wires or threads cannot be attached to a screw head.
- Cerclage wires or threads can then be drawn through these holes and fixed as required.
- Such anchors are known from the company OsteoTec Ltd, England or OBL, Orthopaedie Biosystems Ltd Arizona, USA. These anchors cannot hold a bone fragment with their thread. They are only intended for thread fixation. For each manufacturer's anchor you need a special tool (driver).
- the invention has accordingly set itself the task of designing bone screws with a head for fixation of fractures, in particular for splinter fractures, in such a way that a secure attachment of cerclage wires or threads is ensured in the head of the screws, the screws having commercial dimensions and the Handling with the existing tools of known screws should remain and on the other hand, the additional introduction of anchors can be omitted entirely.
- the ball head of the fracture screw is shaped in such a way that there are four bores in the head of the screw, seen at the end face and at a distance from the hexagon socket, tangentially and in each case offset by 90 °.
- a number of transverse bores are present in the ball head of the fracture screw, with three through bores, seen on the end, in a first plane, each offset by 60 °, in a second plane and rotated to the bores in the first plane, a further three through bores available.
- Fig. 7 shows another fracture screw with several holes in two
- Figure 8 shows a section through the plane A-A
- Figure 9 shows a section through the plane B-B.
- FIGS. 1 to 3 a new type of bone screw 1 is shown, with a head 10 and shaft 20, to which a threaded part 21 - here designed as a cancellous bone thread - is connected.
- this bone screw 1 can also be formed with other threaded parts, for example a cortex thread.
- an internal hexagon 11 is provided for screwing in the bone screw in the head 10.
- a bore 22 can be arranged through the longitudinal axis of the screw 1.
- the contour of head 10 is initially designed as a spherical countersunk head, transition 12 to shaft 20 being rounded and countersunk head-like. From the front view according to Figure 3, the circular shape of the head 10 is interrupted by recesses 14, so that there is a kind of cross.
- Bores 15, 16, 17, 18 are now present tangentially to the central axes and at a distance from the hexagon socket 11.
- the distance between the holes 15-18 to the hexagon socket 11 ensures sufficient material to the shaft 20 to ensure that the bone screws are screwed in and out. It is not shown in more detail that the entry and exit of the bores 15-18 is chamfered or rounded in order to ensure the stability during the later use of a cerclage wire or thread.
- the cutouts 14 can either be made by machining a full head 10 or directly during the hot pressing of the bone screw 1.
- FIGS. 4 to 6 show a further bone screw 30 with a head 31, shaft 32, a threaded part 33, hexagon socket 11 and a central bore 22.
- FIGS. 7 to 9 a further novel bone screw 40 is shown, with a head 41 and shaft 42, to which a threaded part 43 - here formed as a cancellous bone thread - is connected. It goes without saying that this bone screw 40 can also be formed with other threaded parts - for example a cortex thread. Furthermore, a further threaded part is for screwing in the bone screw 40 directly below the head 41
- This threaded part 44 has a 30-40% lower pitch than the threaded part 43 in order to ensure that the screw is stable, i.e. to complicate an independent unscrewing.
- This particular advantage results in the fact that two of these bone screws 40 according to the invention form a tensioning device, i.e. a wire or thread placed through the head 1 of two screws makes it possible to apply tension to a fixation wire by rotating the screws and thus additionally compress a fracture or a tissue part.
- FIG. 8 shows, through the section along the plane A-A according to FIG. 7, a number of bores 46 provided transversely to the screw axis, which are three through bores or six holes 46, which are each offset by 60 ° to one another.
- FIG. 9 shows, through the section along the plane B-B according to FIG. 7, a further number of bores 47, likewise three through bores or six holes, which are arranged offset by 30 ° to the first plane A-A.
- two of these screws 40 according to the invention form a tensioning device, i.e. a wire or thread through the head of two screws 40 makes it possible to apply tension to the wire by rotating the screws and thus additionally compress a fracture or a tissue part.
- the bone screw 40 can have a bore along its longitudinal axis, as is already shown for the fracture screw 30 in FIG.
- the material used for these screws can be one of the known stainless steel alloys that are common in surgical medicine, but they can also be made of plastic.
