摘要

Intramedullary device for osteosynthesis of comminuted fractures of the proximal portion of the femur, comprising a intramedullary nail (1) provided in its upper part by two bearing bolts (2, 3) and a threaded locking plug (6) and in its lower part at least one locking screw (5 ). On the lateral surface of the intramedullary nail (1) is in its upper portion a retaining groove (9) for receiving the closure housing (4), in which are formed two locking openings (10) for the passage to the distal supporting bolt (2) and proximal support bolt (3). Above the surface of the two carrier screws (2, 3) are staggered locking stop (7) for fixing the two supporting bolts (2, 3) in the locking hole (10) closing the housing (4) by means of a threaded locking caps (6) above abutting on the upper face of the closure housing (4).
