Claim Text:
1. An intramedullary fixation device used in bone fixation and stabilization on a patient, comprising: a longitudinally extending rigid body having a rigidity sufficient to withstand bending loading applied by the phalanges, the rigid body having a longitudinal axis extending through at a least a portion of the body; a distal head disposed at a distal end of the body and sized for insertion into an intramedullary canal of a phalanx of the patient, the distal head having a central core portion and a plurality of extending distal wings radially projecting from the central core portion, wherein the radially projecting distal wings are spaced asymmetrically about the central core portion; and a proximal head at a proximal end of the body and sized for insertion into an intramedullary canal of a phalanx of the patient, the proximal head having central core portion and a plurality of proximal wings extending radially outwardly from the central core portion, wherein each distal wing comprises an outer surface portion, the outer surface portion comprising an outer perimeter surface portion and a curved leading surface portion extending longitudinally between the outer perimeter surface portion and the central core portion of the distal head, the curved leading surface portion curving longitudinally from the outer perimeter surface portion and smoothly intersecting at the central core portion of the proximal head.
