摘要：
A bone screw includes a screw shaft with an external thread. The screw shaft anchors the bone screw in a bone. A proximal end of the screw shaft includes a screw head. The ratio between the outer thread diameter and the thread core diameter increases toward the screw head in a proximal screw shaft portion or in the area of the threads run-out.
