A bone screw comprising a first end having an engagement contour for engaging with a tool to facilitate insertion or removal of the bone screw, and a blocking element is arranged at a second end thereof. The blocking element is provided with a circumferential outside surface which comprises at least one clamping surface which&#x2014;when viewed in an azimuth plane perpendicular to a longitudinal axis of the bone screw&#x2014;widens outwardly in a wedge-shaped manner away from the longitudinal axis. 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. At least one bone screw and at least one bone plate together form a surgical set.

An osteosynthesis plate according to the invention has at least two legs, which are spaced apart and interconnected by at least one bridge element. The legs each have a certain length and extend in the longitudinal direction from an epiphyseal to a diaphyseal end of the osteosynthesis plate. Moreover, each leg has at least one opening for holding an anchoring element. The size and shape of the bridge element and the legs are configured such that the legs may be applied on both sides of a bone in the region of a joint, preferably on the olecranon.
