Abstract
An osteosynthetic fixation device consists of a fixation element 1 which has a conical head section 11 and an anchoring element 12 abutting it which is for attachment into the bone. The fixation device also consists of a spherically formed, layered, slotted clamping piece 2 which has a conical borehole 21 for installation of the conical head section 11, and which is meant for locking within a connecting piece 3 equipped with a spherically shaped layered borehole 31. Fixation piece 1 has an axially arrayed tension element 4, permitting axial displacement and wedging of conical head section 11 in the borehole 21 that corresponds with it. The fixation device is appropriate for use as a plate/screw system, an internal or external fixator, and in particular for spinal column fixation.
