A rigid rod made of metal or other material intended to be implanted into the intramedullary canal of the femur to immobilize the ends of a fractured bone in position to promote healing; it is not dedicated to extension beyond the joint to an adjacent bone (i.e., not dedicated to arthrodesis/joint fusion). It may be a locked or unlocked model and may include components to assist fixation of more proximal or distal conditions. This is a single-use device.
