ABSTRACT:
A device for facilitating the ventral screwing together of dens fractures with compression screws, characterized by a guide tube assembly comprised of two guide tube casings which are pivotably joined near one end by means of an articulated joint, and which are adjustable within a predetermined range of angles by an adjusting means. Bore wires, milling tools and compression screws can be introduced into the dens via the guide tube assembly at precise spatial and angular relationships set by the aiming tube assembly.
