Abstract: An intramedullary locking nail for the treatment of femoral neck fractures has a generally elongate body. The elongate body has a longitudinal axis, a proximal portion and a distal portion, wherein the axis is bent between the proximal and distal portions. The proximal portion has a transverse passageway inclined to the axis for receiving, in use, a femoral neck blade. The passageway is formed by two pairs of opposing walls, one of the pairs of opposing walls has walls that are substantially flat and lie in planes that are substantially parallel to the longitudinal axis of the nail. The distal portion has at least one cross bore having a generally oblong cross-section for receiving, in use, an element for locking the nail to a patient's bone. The oblong cross-section of the bore permits, in use, selection in the degree of anchoring of the nail to the bone depending upon where the locking element is located in the bore.

Abstract: Osteosynthesis auxiliary (10) for the treatment of subtrochanteric, peritrochanteric and femoral-neck Fractures, with a locking nail (12) that can be introduced from the proximal end into the medullary space of a femur(11) and that comprises a distal section (15) having at least one oblong cross bore (13) to receive a distal locking element as well as a proximal section (14) having a slanted passageway (16), and with a femoral-neck part (19) that can be introduced from a lateral position through the slanted passageway (16) into the neck (17) and head (18) of the femur, wherein at least the section of the femoral-head part that can be anchored in the head (18) of the femur has a cross section that is not circular or rotationally symmetrical. Preferably this section (34) has the shape of a double-T or I profile (35).
