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 used in stabilising operations on the thoracic and lumbar vertebral column for restoring the load-bearing capacity of the vertebral column is provided. An insertion region of the implant (I) comprises a wedge-shaped distraction part (C), which permits the vertebral bodies to be pushed apart in order to increase the intervertebral distance. In addition, guide elements in the form of grooves (7) and/or strips are provided on said wedge-shaped distraction part (C) and/or in the implant part (D).

Abstract: The invention concerns an implant in the form of a compression resistant hollow body (1), used in procedures for stiffening the vertebral column (2). The hollow body (1) includes two open receptacles (3, 4) mutually oriented toward one another that interlock and form the implant proper (cage). The two receptacles (3, 4) can be separated by pressure through insertion of a filling material, thereby producing an expansion of the hollow body (1) after it has been implanted.

Abstract: An osteosynthesis screw (1) used especially for application by a translaminar vertebral screw, comprises a shaft (3) at least partially provided with a thread (2) and a head (4) formed at one of its ends and having a notch (5) for a tool. Said shaft (3) has a section (A) with a thread (2) on the end section oriented towards the head (4). The remaining section (B) of the shaft (3) up to the free end is produced without a thread. The head (4) has a diameter (D1) corresponding at least approximately to the outer diameter (DA) of the thread (2) and is provided with the inner notch (5) for a tool. The section (A) of the shaft (3) with the thread (2) has a configuration of uniform thickness, e.g. a trilobular configuration. Thus, the invention provides an osteosynthesis screw (1) exhibiting a short section (A) with a thread (2) and a long section (B) without a thread, said screw having a pull-out head (4) which is secured both axially and rotationally.

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.
