INTRAMEDULAR STEM FOR USE IN TREATMENT OF Femoral Fractures, Apparatus for Internal Fixation of a Fracture, and Method for Treating Femoral Fractures. This invention relates generally to devices, systems and methods for internal fixation of bone fractures, and particularly to intramedullary fracture fixation devices, such as those used, for example, in the treatment of long bone fractures. An IM rod is preferably provided with multiple curved sections on different pianos, preferably designed to fit the shape of a patient's long bones, both during insertion and in the final position of the rod in the long bone. In addition, the overlapping of the curved section parts results in a coplanar curvature of IM stem parts that assists in the insertion process, guiding the proper rotation of the IM stem as it is inserted into the bone. Spiral ribs extending below the distal part of the nail also help to properly guide and orient the nail around its geometric axis during insertion, so that the appropriate segment of the curved nail fits into the shape of the appropriate portion of the long bone. in the appropriate place.
