Abstract:
1. An intramedullary nail to be inserted into a fractured elongated bone comprising: a cannulated rod extending between a proximal end and a distal end; an outside tubular sleeve for hosting said rod, the rod being coaxial with the sleeve and axially or angularly guided inside the tubular sleeve; shape memory elements hosted in corresponding seats of said rod; each element being able to assume a first configuration wherein it is retractably housed in its respective seat, so to allow the insertion of the nail in the bone, and a second configuration wherein the element is projecting from an opening slot of said sleeve; wherein: a proximal pair of said shape memory elements is provided at the rod proximal end and a distal pair of said elements is provided at the rod distal end; the shape memory elements of the proximal pair lie on a same plane and are kept in their corresponding seats by a proximal cover; the shape memory elements of the distal pair lie on a offset plane with respect to the plane of the elements of the proximal pair, and are kept in their corresponding seats by a distal cover; and the distal cover is formed by two portions that are connected by one corner and are extended in perpendicular planes.
