A bone nail of elastic material bent at least in its proximal end portion and insertable into the medullary canal of the bone through an impact hole formed proximal to the knee joint area of the bone has the same cross section in its distal end area as the entire nail and is provided with a flattening for forming a coupling element for the non-rotatable connection with the tool in at least one site of the nail periphery at a distance from the distal nail end, with at least the front face immediately adjacent the distal nail end via which the flattening merges with the periphery of the bone nail, preferably both opposing front faces, extending inclined to the flattening, and thus form an angle deviating from 90 degrees, peferably an angle of about 45 degrees, with said flattening. |
