A device for handling a bone screw to be connected with a vertebral rod includes an essentially cylindrical and hollow housing and an adjustment tool which axially traverses the housing and which has a section provided with an outer threading and is screwed into an internal threading of the housing, wherein the housing is constructed pliers-like and has a first and a second jaw which relative to the user each have a proximal and a distal end, wherein the distal ends engage at the head of the bone screw, wherein the two jaws are pivotably connected with each other via a pivot axis which is situated between the distal and proximal ends and extends orthogonally in relation to the longitudinal axis of the housing, and wherein the internal threading of the housing is provided on a proximal end of a single one of the jaws.

Device for handling a bone screw

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.

Bone plate

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.

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.

Bone screw

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.
