Bone nail for the intramedullary compression nailing of femoral fractures

摘要

Bone nail for the intramedullary compression nailing of femoral fractures with an intramedullary nail (10), with a tension bolt (20), with a compression sleeve (30) and with a compression bone screw (40), wherein the intramedullary nail (10) a counter to its axis inclined angle bore (15), wherein the tension screw (20), fixed against relative rotation, in the compression sleeve (30) is guided, wherein the compression sleeve (30) into the angle bore (15) of the intramedullary pin (10) can be inserted and in this angle bore (15) is axially supported and wherein the compression bone screw (40) in the compression sleeve (30) is supported and the tension screw (20) in the compression sleeve (30), characterized in that the angle bore (15) has an internal thread (16), that the compression sleeve (30) with an external thread (32) in the internal thread (16) of the angle bore (15) and that can be screwed to the axial support of the compression sleeve (30) the angle bore (15) has a stop shoulder (17), against which the external thread (32) of the compression sleeve (30) comes to rest.
