Abstract
The invention discloses an intramedullary nail to be used in orthopedics comprising: a tubular body having inside at least one anchoring device; a maneuvering element and a drilled bushing at the top end of said nail wherein said tubular body, substantially cylindrical, has the top end not cylindrically shaped. The anchoring device is provided with two or more longitudinal cavities shaped for housing a hook with arched tip pointed towards the outer side of the tube and movable with respect to the housing cavity during the sliding of the anchoring device with respect to the tube. The maneuvering element, housed inside the tubular body, operates the longitudinal sliding in the two opposite directions of said anchoring device. The drilled bushing slides without rotation with the non-cylindrical top end of said tubular body and has at least one arched lip for the contact with the bone.
