摘要：
The invention relates to a bone screw comprising a first end having an engagement contour, wherein the engagement contour is arranged for engagement with a tool for inserting or removing the bone screw, and a second end which is situated opposite the first end and on which a blocking element is arranged, wherein the blocking element is provided with a circumferential outside surface which comprises at least one clamping surface which—when viewed in an azimuth plane perpendicular to a longitudinal axis of the bone screw—widens outwardly in a wedge-shaped manner away from the longitudinal axis. The invention also pertains to surgical sets including at least one bone screw and at least one bone plate. The bone screw comprises a first end having an engagement contour, wherein the engagement contour is arranged for engagement with a tool for inserting or removing the bone screw, and a second end which is situated opposite the first end and on which a blocking element is arranged, wherein the blocking element is provided with a circumferential outside surface having an outer contour. The bone plate includes at least one opening which is at least partially delimited by an inside wall having an inner contour for receiving and fixing the blocking element of the bone screw.
