Abstract: The present invention relates to a screw drive having integrated torque protection, wherein two screw drives are incorporated in a screw head, one drive being an internal polygonal drive and the second drive being an internal multilobular drive. In addition, the invention relates to a screw having a screw drive.

Abstract: A resorbable implant for osteosynthesis for stiffening in a central joint (e.g., the proximal interphalangeal joint referred to as PIP) during arthrodesis or for stiffening in an end joint (e.g., the distal interphalangeal joint referred to as DIP) during arthrodesis and for osteosynthesis and stabilization of fractures of small bones of the human skeleton includes two shafts placed against each other. At least one fixing aid is located between the shafts. The fixing aid protrudes beyond a diameter of the shafts. Each shaft may have longitudinal grooves and transverse grooves. The implant is a magnesium-based material which can be resorbed by the human body. The disclosed implant has a relatively high tensile strength, excellent stability, optimal healing properties, and an optimally adapted resorption speed.

Abstract: The invention relates to a wire implant, in particular for wire osteosynthesis, and a corresponding method for its production. The wire implant has been subjected to a heat treatment, wherein the wire implant consists of a biocompatible, biocorrodible magnesium alloy, which is composed of metallic magnesium of at least 80 wt. % a zinc proportion of 0.1 to 2.0 wt. %, a zirconium proportion of 0.1 to 2.0 wt. %, a proportion of rare earth metals of 0.1 to 10 wt. %, wherein the yttrium content among the rare earth metal content proportion is 0.1 to 5.0 wt. %, a manganese proportion of 0.01 to 0.2 wt. %, an aluminium proportion of less than 0.1 wt. %, a proportion of copper, nickel and iron of less than 0.10 wt. % in each case, and a proportion of other physiologically undesirable impurities totaling less than 0.8 wt. %, wherein the remainder of the alloy is magnesium up to 100 wt. %.

Abstract: The invention relates to a fixation nail for temporarily securing transplantable tissue, bone parts, and bone replacement substances using a cover or for securing natural or artificial bone replacement parts to bones. The fixation nail has a round flat nail head with a diameter of 0.50 to 6.0 mm, and the thickness of the nail head is 0.10 to 2.0 mm. The fixation nail has a nail pin which is formed with a sharp tip, and the pin has a length between 0.5 times to 2 times the diameter of the nail head and a thickness between 0.15 times to 0.5 times the diameter of the nail head. The fixation nail consists of a biocompatible, biocorrodable magnesium alloy which is composed of at least 90 wt. % metal magnesium and contains less than 0.1 wt. % aluminum, less than 0.1 wt. % copper, less than 0.1 wt. % iron, and less than 0.1 wt. % nickel as physiologically undesirable impurities.

Abstract: The invention relates to an implant for the osteosynthesis of the PIP arthrodesis or the DIP arthrodesis of small joints and for the osteosynthesis and stabilisation of fractures of small bones of the human skeleton, said implant being resorbable by the human body. The implant consists of two shafts placed against each other. At least one fixing aid is located between the shafts, said fixing aid protruding beyond the diameter of the shaft. Each shaft can optionally have longitudinal grooves and transverse grooves. The implant consists of a magnesium-based material which can be resorbed by the human body. The invention provides an implant which has an extremely high tensile strength, excellent stability, optimal healing properties, and an optimally adapted resorption speed.

Abstract: The invention presently proposed relates to a method and an apparatus for intelligently composing a multimedia message for a mobile radio system. In this method, a digital voice message is received from a digital answering service, a blank multimedia message is generated and the received multimedia message is added, the available amount of data remaining in the multimedia message is calculated, the digital voice message is analyzed, and a suitable multimedia content is selected in dependence on the remaining available amount of data in the multimedia message and the analysis result, and finally the multimedia content thus selected is added to the multimedia message including the received digital voice message.

Abstract: The invention is directed to a method for absorbing energy in a motor vehicle seat in the case of a collision etc., and to an energy-absorption device for implementing said method. The method comprises the step of providing a removable deformation element in or at the vehicle seat, preferably in a space thereto provided in the fitting provided for inclining the backrest of the vehicle seat. The energy-absorption device implemented as the deformation element comprises at least one deformation portion which is deformable in a collision, thus absorbing energy. The invention is also directed to a fitting for inclining the backrest, the fitting having a space for mounting the deformation element. The invention is in especially provided to avoid in particular damages to the nape of the neck in the case of collisions from the rear.
