In this accidentthe pushing or gliding resistance of the bone is overcome. Fracture by torsion (Plate 2) is produced by a rotatoryforce overcoming the rotatory resistance or resistance to tor-sion of a long bone. Rotation of the bone eventuating infracture is possible whenever one segment of the bone isfixed while the remaining segments are rotated. Thus, atorsion-fracture may be produced either by rotating thedistal portion of the limb while the body remains fixed,
