      is broken into several parts.

   {Complicated fracture} (Surg.), a fracture of the bone
      combined with the lesion of some artery, nervous trunk, or

   {Compound fracture} (Surg.), a fracture in which there is an
      open wound from the surface down to the fracture.

   {Simple fracture} (Surg.), a fracture in which the bone only
      is ruptured. It does not communicate with the surface by

   Usage: These words denote different kinds of breaking,
          according to the objects to which they are applied.
          Fracture is applied to hard substances; as, the
          fracture of a bone. Rupture is oftener applied to soft
          substances; as, the rupture of a blood vessel. It is
          also used figuratively. ``To be an enemy and once to
          have been a friend, does it not embitter the
          rupture?'' --South.
