ABSTRACT:
The invention relates to a bone screw (10) which can be anchored in the bone in a firm and vacuum-tight manner, and to the use of the same in arthroplastic surgery and as a drug delivery system. The interior of the bone screw (10) has a continuous longitudinal bore (15) through which the medullary canal can be evacuated during the application of bone cement. The use of the bone screw renders it possible to fill the spongiosa honeycombs with bone cement without endangering the life of the patient.
