In order to produce a bone screw having a screw body which is provided with an external thread and which comprises a flow-through mechanism for bone cement that is used for the production of a cement jacket around the bone screw, such that the bone screw will be anchored in a highly stable manner after being implanted in a bone and especially after being implanted in a bone of reduced quality, it is proposed that the flow-through mechanism should comprise at least one longitudinal recess which is formed in the screw body such that it extends transversely relative to the radial direction and/or transversely relative to the peripheral direction.
