Abstract: Surgical implant for treating fractures of long bones, notably of the femur, having an intramedullary section (52) of elongated shape, adapted for being inserted into the medullary cavity (37), an extramedullary section (56) substantially parallel to the intramedullary section (52), a deformable curved loop (57) connecting the intramedullary section (52) to the extramedullary section (56), an inclined screw (61) traversing said intramedullary section (52) and said extramedullary section (56). By deforming the loop (57), a continuous adjustment of the angle (?) of the cephalic screw (61) and thus an optimal adaptation of the implant to the individual anatomy can be achieved. Thanks to its geometry, this implant induces a protection of the greater trochanter and limits the mechanical loads between the cephalic screw (61) and the rest of the implant.
