Abstract
A nail for fixing the position and shape of broken long bones is provided. The nail has a longitudinal shank defining a central main body and longitudinal extending, radially directed, ribs, preferably one or more. The nail and ribs are collapsed in diameter when inserted into the broken bone and then, by introducing a fluid into the hollow nail, the diameter of the nail increases such that the rib(s) contact the interior of the broken bone.
