Abstract: A bone plate for osteosynthesis having a plate-shaped base and a top, with the base defining only a single receiving opening for retaining a bone screw that attaches it, for example, to a vertebra.

Abstract: The invention concerns a bone plate which can be mounted to a vertebra. This is effected by bone screws which engage in the opening of the bone plate. At least one of the openings of the bone plate serves for receiving the screw head of the bone screw and is provided with a surface structure.

Abstract: The invention concerns a bone screw comprising a screw shaft and a forked head into which a correction rod can be fixed. The forked head bears a nut which is connected to the forked head by a bayonet joint.

Abstract: An osteosynthesis device includes a bone screw and a correcting rod which is positioned and axially fixed in a fork head of the bone screw. To this end, the fork head includes means which prevent the longitudinal displacement of the correcting rod. In addition, the screw shank of the bone screw is mounted in the fork head such that it is able to move in relation to same and in the area in which it receives the screw shank said fork head is configured as a hollow cone.

Abstract: The present invention relates to an intervertebral implant for insertion between two vertebral bodies of a spinal column, comprising a body containing two contact faces, whereby the body is designed as a hollow body, and the hollow body is formed by a side wall which has a convexly curved longitudinal wall portion and a concavely curved longitudinal wall portion as well as two convexly curved lateral wall portions connecting the two longitudinal wall portions with each other, whereby the radii of curvature of the lateral wall portions are smaller than the radii of curvature of the longitudinal wall portions.

Abstract: The present invention relates to an osteosynthesis device with a bone screw and a correction rod, in which the correction rod is placed in a bifurcated head of the bone screw and axially fixed. To that end, the bifurcated head has structure that prevent the longitudinal displacement of the correction rod.

Abstract: An osteosynthesis device having a bone screw, particularly a pedicle screw, a fork head that has a groove and a corrective pin seated in the groove of the fork head. A corrective pin is secured against twisting in that the bottom of the groove of the fork head is provided with a plurality of longitudinal slots lying parallel to one another.
