Abstract
An intramedullary (IM) nail system for the fixation of fractured bones in a patient comprising a nail and compression screws. The length of the body is divided into a distal section and a proximal section with the distal section containing multiple interference sections having a diameter less or greater than that of the body. The threads adjacent the nail head have an apex generally greater than the diameter of the body. The compression screws are dimensioned to be inserted through the bone and contact the nail, pressing it against the bone canal. The nail, once inserted, lies below the surface of the bone.
