Abstract

See full text

A screw for fixation of, for example, a fracture having a hollow shaft, a first outer thread and radial openings at its distal end, and a second outer thread and an inner engagement portion at its proximal end. The second outer thread is adapted to engage with a tissue protection sleeve. The inner engagement portion is adapted to fit to a driving end of a driving tool. By way of this, forces in axial or radial direction may be applied to the screw by the sleeve, and forces in rotational direction may be applied by the driving tool. Therefore, the screw can be installed accurately at the intended site in an object.
