The subject of the invention relates to a set of surgical instruments for the fusion of vertebrae that contains supporting elements that have a threaded stem that can be screwed into the vertebra and a head part of positioned at the outer end of the threaded stem, a connection unit that is fitted between the supporting elements and a fixating device serving to brace together the supporting elements and the connection unit, and the head part of the supporting element has an accepting opening suitable for joining the connecting unit. The characteristic feature of the invention is that the accepting opening (14) is formed by the unification of the introductory cleft (15) running from the outer surface (13) of the head part (12) and penetrating into the head part (12) and the lead-through seat (16) that forms the continuation of the introductory cleft (15) and is worked into the head part (12) and that the bells out from there, furthermore, the head part (12) has a fusion opening (17) that has a first connection piece (18) and ends in the lead-through seat (16), the fixating device (30) has a tightening body (31) that is positioned in the fusion opening (17) so that it may move and that has a second connecting piece (32) that operates in unison with the first connecting piece (18), and the connecting unit (20) is assembled from the group of the elemental connection strands (21) penetrating the introductory cleft (15) of the head part (12).
