The bone plate includes an upper side, an underside facing the bone, a middle part and, adjoining thereon, a peripheral region, which encloses the four extensions of the �X� and in which four plate boreholes are accommodated. The plate boreholes have means, which are suitable for the rigid, angularly stable anchoring of bone screws which may be introduced therein. Images(3) Claims(20)
DESCRIPTION OF THE PREFERRED EMBODIMENTS The bone plate 1, shown in FIGS. 1 and 2, may comprise an upper side 8, an underside 9 facing the bone, a middle part 2 and, adjoining thereon, a peripheral region 3, in which four plate boreholes 4 are accommodated. The four plate boreholes 4 have means 5, which are suitable for the rigid, angularly stable anchoring of bone screws 10, which are to be introduced therein. These means 5 may consist of the plate boreholes 4 tapering conically towards the underside 9. Bone screws 10 with a correspondingly conically constructed head 11 can then be connected angularly stably and in a rigid manner with the bone plate 1. The means 5, as shown in FIG. 3, may additionally comprise an internal thread 14. The bone plate 1 may have a shape of an �X�, the peripheral region 3 comprising the four arms of the �X�. The four plate boreholes 4 may preferably be disposed at the ends of the four arms of the �X� at the corners of an imaginary rectangle. The angles, formed by the four arms of the �X� may be rounded. The four plate boreholes 4 have central axes 6, which converge toward one another underneath the underside 9 of the bone plate 1 and may intersect essentially at a point 7 such that when bone screws 10 are introduced into the bone plate 1 they do not collide with one another when the bone plate 1 is bent. The normal at the center of the middle part 2 of the bone plate 1 may extend through the point 7 (FIG. 3). The bone plate 1 accordingly has two planes of symmetry, which are orthogonal to one another. By this configuration, the bone plate 1 can be used in any direction, without consideration to any special offset angle. The perpendicular line at the center of the middle part 2 of the bone plate 1 may also pass through the point 7. As shown in FIG. 3, the bone plate 1 may accommodate four bone screws 10 (FIG. 4) comprising a head 11 and a shaft 12. The head 11 having means 13 in the form of a conical, external thread, which permit a rigid, angularly stable anchoring in the plate boreholes 4. The head 11 of the at least one bone screw 10 may also consist of a material, which is harder than the bone plate 1 in the region of the plate borehole 4, such that the head 11 having an external thread which, when screwed into the plate borehole 4, cuts a corresponding thread. The bone plate 1 lies in one plane and can be bent at will by the user. The four arms of the �X� of the bone plate 1 can be bent with respect to the middle part 2, so that the bone plate 1 can be adapted to the contour of the bone. The bone plate 1 may, however, also be made available already pre-bent to the user. There may be two planes of symmetry of the bone plate 1, which are orthogonal to one another. In one embodiment, at least one of the plate boreholes 4 has a central axis 6, which is not parallel to the line perpendicular to the middle part 2. Bone screws 10 introduced into the plate boreholes 4 do not collide with one another when the bone plate 1 is pre-bent over one of the two middle axes. One of the angularly stable screws can be set in such a manner that it goes beyond the osteotomy or the fracture, providing increased stability for the connection of the two bone fragments. The number N of plate boreholes 4, which have a central axis 6, which are not parallel to the line perpendicular to the middle part 2 is two, three or four. At least a part of the plate boreholes 4 may taper conically towards the underside 9 facing the bone. This tapering, means 5, may be suitable for rigid, angularly stable anchoring of bone screws 10 into the plate boreholes 4. These means 5 may also consist of an internal thread of the tapered plate boreholes 4. Bone screws 10 may be introduced at an angle into the plate boreholes 4, in order to cross the osteotomy, the bone fracture or the joint, so that the stability also comes from the bone screw 10 itself and not only from the bone plate 1 in conjunction with the bone screw. The quadrangle, mounted by the four plate boreholes 4, may preferably have a height of about 10 to 40 mm and a width of about 10 to 40 mm. The thickness of the bone plate 1 may be greater in the region of the plate boreholes 4 than in the regions between the plate boreholes 4. Further, the minimum height in the region about the plate boreholes 4 must exceed a certain value, and that the plate boreholes 4 are deformed only minimally if at all when the bone plate is bent.
