Abstract: The invention relates to an orthopedic fixation device with an at least partly shaft-like fixation member, a shaft-like mounting body, and a transverse support securing the fixation member and the mounting body in a position in which they are laterally offset from one another. In order to adjust the transverse support without having to change the position of the fixation member, the fixation member can be rotated about its longitudinal axis in the transverse support and can be secured in a defined angular position.

Abstract: The invention relates to an orthopedic fixation device for securing a rod-like fixation element, with two clamping jaws which can be moved relative to one another and which, when brought together, clamp the fixation element between them. In order to permit space-saving configurations of a fixation device that can be introduced and operated through small orifices in the body, a cam body is provided which is mounted on the fixation device so as to be able to rotate next to the clamping jaws in the direction of tightening and which, when rotated, pushes one clamping jaw toward the other.

Abstract: A locking mechanism for securing a bone screw 20 to a clamping element 30 of an osteosynthesis holding system 5 is provided. The bone screw 20 has a circumferential groove 25 located on a top portion of the screw 20 below a screw head 22. Snap catches 35 protrude from a bone-contacting surface 38 of the clamping element 30 and interlock with the groove 25 in the screw 20 when the screw 20 is inserted into the clamping element 30 (e.g., when the screw is screwed into a bone segment through a hole in the clamping element). A removal device 90 is provided for removing the screw 20, as a greater axial force is required to overcome the locking mechanism than is needed to engage the locking mechanism. A method for revision (removal) of the screw 20 from the locking mechanism is also provided.

Abstract: A Kirschner wire 10 for use in endoscopic surgery is provided, as well as methods and apparatus for installing and removing Kirschner wire 10. Kirschner wire 10 has a holding device 20 for ease of insertion and removal. Kirschner wire 10 is sufficiently short so as not to protrude from the working channel of the endoscope. Insertion instrument 30 has a receptacle 40 which for engagement with holding device 20 of Kirschner wire 10. A targeting ring 46 on insertion instrument 30 enables placement of Kirschner wire 10 under x-ray supervision. Removal device 60 has a wire body 62 with a receptacle 64 located at a distal end thereof for engagement with holding device 20 of Kirschner wire 10. Kirschner wire 10 may be adapted for use in marking a point of entry for a cannulated bone screw or as a point of orientation for an endoscopic procedure.
