Abstract: A composite of polymer or ceramic material has reinforcing fibers. The composite is for use in manufacturing medical implants like osteosynthesis plates, endoprostheses, screw coupling elements, surgical instruments, and similar components. The fibers and fibrous parts are made from a material that absorbs X-rays so that it can be seen during X-ray examination.

Abstract: An implant for osteosyntheses including a plate with a plurality of holes following in succession in the longitudinal direction whereby at least most of the holes intended to receive the screws are offset in alternation generally away from a center plane whereby a center axis of each of the holes forms an acute angle with the center plane of the plate.

Abstract: The invention relates to a device for the introduction of medical items into the human or animal body. The device comprises a longitudinal guide sleeve or member having a first end segment, a second end segment, a longitudinal axis, and an outer surface. The second end segment defines a chamber and includes a drive element, which may be configured to couple to another drive device for rotatably driving the longitudinal member. The first end segment includes a screw thread for anchoring the device to bone such as a pedicle in the spine. The thread defines either a cylindrical or prismatic thread root or thread surface. The first end includes self-cutting teeth and at least one slot that extends along the outer surface between the self-cutting teeth and the second end segment in communication with the chamber.
