Intramedullary nail for the treatment of fractures of the long bones

An intramedullary nail for the treatment of fractures of long bones, in particular a pertrochanteric nail for the treatment of fractures of the femur, comprising:

• a nail body with a proximal area and a distal zone and a longitudinal axis, said body of said nail being adapted to be inserted in the medullary canal of said long bone, said nail having at least two through holes formed in the proximal area of said body,
• said nail having a pair of fastening elements each having a first and a second end, each fastening element being adapted to be housed in a respective hole of the body of said nail at the respective first end, wherein said second ends of said fastening element are adapted to engage the cancellous bone of the long bone head at the fracture to be treated,
• said fastening elements being configured so that they can be bound to each other in the vicinity of the respective second end in a constraint configuration and, once bound, so as to be displaceable independently of one another, so that, during use, by acting on the respective first end of one or each fastening element, it is possible to act on the long bone head, moving it in a direction substantially parallel and transverse to the axis of the nail, to realize a reduction of the fracture fissure by both bringing closer the fragment of the fracture and allowing its vertical realignment,
• wherein said first fastening element has an intermediate portion between said first and second ends and in that said second fastening element has an opening adapted to receive said intermediate portion of said first fastening element, said opening having a size that, when said fastening elements are bound to each other in said constraint configuration, the passage of said first end of said first fastening element by the translation of said first fastening element in the absence of rotation is prevented, and to allow the release between said fastening elements from said constraint configuration, only by at least one rotation of said first fastening element relative to said second fastening element,
• wherein said intermediate portion of said first fastening element has a thickness smaller than the thickness of the respective second end and presents a smaller thickness than said opening of said second fastening element to be able to move freely with respect to said opening also in said constraint configuration.
