PROBLEM TO BE SOLVED: To provide a system for stabilizing the spine, which can arrange a fixation screw at a position wherein the fixation screw can be fixed to the bone tissue in the best possible manner. SOLUTION: This invention relates to a system and method for stabilizing the spine. The system comprises a fixation screw with a threaded section, and a fixation plate with a top and bottom surface. The fixation plate has a pre-drill hole arranged on the side of the top surface, and with the pre-drill hole, an actual fixation hole is made in the plate. The fixation hole is made when the plate is arranged at its future fixation point on the surface of bone tissue such that the fixation hole forms a first angle relative to the plate, whose size is selectable from several alternatives within certain limit values. The threaded section of the fixation hole is made during the same work stage as the threaded section in the bone tissue. COPYRIGHT: (C)2006,JPO&NCIPI
