Abstract: An endoprosthetic component which is set up in the implanted state to penetrate in a controlled manner into adjoining bone material.

Abstract: The invention relates to a cutting broaching tool (1) for intraoperatively obtaining bone material from a patient, comprising a main part (3) which rotates about a rotational axis (2) for securing on a rotating tool support and comprising at least one blade (4) which is rigidly connected to the main part (3). The aim of the invention is to prevent the tissue from reacting when using the broaching tool and thus prevent an increased risk of infection, to prevent a thermal load on the bone, to receive the bone material in the interior of the broaching tool, and to discharge the bone material to an external device. This is achieved in that the main part (3) has a cylindrical shape, is hollow, and surrounds a first cavity (5). The blade (4) or all the blades (4) are formed integrally with the main part (3), extend in the direction of the rotational axis (2) of the main part (3) at a distance from an end face (6) of the main part (3), and surround a second cavity (7).

Abstract: A spinal implant comprising an upper and a lower end plate connected by inner and outer lateral walls, said outer lateral walls forming an anterior wall, a posterior wall and two longitudinal walls, said inner lateral walls encompassing a receiving space, and engagement elements being arranged on and projecting from said upper and lower end plates. According to the invention, in order to avoid wear and abrasion when implanted and to improve ingrowth of the spinal implant into the tissue, said spinal implant consists of a ceramic material and carries a porous ceramic foam in at least some sub-sections.

Abstract: The invention relates to components for fusing vertebral bodies and to methods for the production and use thereof.

Abstract: A screw which is self-locking screw has an elliptical screw body. The screw may be used, e.g., to secure implants such as spinal implants or, e.g., to secure bone or plants.

Abstract: Ceramic components for replacing joint surfaces, and methods for production thereof. In particular, the invention relates to ceramic joint surface implants which completely or partially replace natural cartilage.

Abstract: Implants that have anchoring elements, which are vertebral implants that can be used as intervertebral disk replacement in the form of cages for the fusion of vertebral bodies.
