Abstract:
1. A combination comprising an intramedullary nail and a targeting and/or nailing instrument, a connection end of the targeting and/or nailing instrument having an axially parallel protrusion and a connection end of the nail having an axially parallel recess in order to fix together the targeting and/or nailing instrument and nail in their rotational position when they contact axially and whereby a means for connecting the nail and targeting and/or nailing instrument are also provided in order to connect the targeting and/or nailing instrument and the nail in an axially fixed but also releasable manner, wherein the connection end of the targeting and/or nailing instrument has an end section that engages in one end of a bore-hole section of the nail by means of a releasable snap connection of the parts with the simultaneous contact of axially parallel protrusion and axially parallel recess; wherein the end of the bore-hole section of the nail has a circular groove, in which a spring element of the snap connection expands radially if the end section is inserted into the bore-hole section; wherein the axially parallel protrusion has a distal section and a width which decreases towards the distal section; wherein the protrusion has an external diameter equal to the external diameter of the connection end of the targeting and/or nailing instrument; and wherein the axially parallel recess of the connection end of the nail is a slotted recess in a wall of the bore-hole section of the nail.
