Abstract

The present invention relates to a device for fixating and adjusting the position of vertebrae in conjunction with vertebral surgical operations, comprising two mutually crossing and generally rod-shaped implant elements. For the purpose of locking the implant elements together, the device (1) further comprises four generally parallel, elongated elements (B, C, D, E) projected onto a plane that passes through two of the elements whose ends are generally located in the corners of a parallelogram, preferably a square. The ends of the elements are mutually joined together in pairs by mutually parallel part-hoops (7, 9; 8, 10) which curve outwards from the ends of the elongated elements, wherein the pair of part-hoops (7, 9) at one end of an elongated element are perpendicular to the pair of part-hoops (8, 10) at the other end thereof, wherein the part-hoops of each said pair embrace a rod-shaped implant element (5, 6, 11a, 17) together with a respective adjacent, crossing rod-shaped element, wherein those sides (13, 14, 13', 14'; 15, 16, 15', 16') of the elongated elements that lie against a rod-shaped element are essentially flat and essentially parallel with respective opposing sides of an adjacent elongated element in fixating and positionally adjusting a vertebra.
