摘要：
The present invention relates to an intramedullary nail (10) for the treatment of fractures of long bones in particular pertrochanteric nail (10) for the treatment of femur fractures. Said nail (10) presents a body (1) having a proximal area (11) and a distal area (16) and a longitudinal axis (15) and is adapted to be inserted in the medullary canal of said long bone. Furthermore said nail (10) presents at least two through holes (12 13) formed at the proximal zone (11) of said body (1) The nail (10) comprises a pair of fastening elements (2 3 6 7) each having a first ( 26 36 66 76) and a second (27 37 67 77) end in which each fastening element (2 3 6 7) is adapted to be housed in a respective hole (12 13) of the body (1) of said nail (10) at the respective first end (26 26 66 76). The second ends (27 37 67 77) of said fastening element (2 3 6 7) are adapted to engage with the cancellous bone of the long bone head in correspondence of the fracture to be treated. The fastening elements (2 3 6 7) are configured so as to be fastenable to each other in the vicinity of the respective second end (27 37 67 77) in a constraint configuration and once constrained to be movable independently of each other in such a way that during use by acting on the respective first end (26 36 66 76) of one or each fastening element (2 3 6 7) one can act on long bone head moving it in a direction substantially parallel and/or transverse to the axis (15) of the nail (10) to realize a reduction of the fracture fissure both bringing closer the fragment of the fracture and allowing its vertical realignment.
