Torsiofi of the Uterus

unless the revolution has reached the quadrant of a circle, 90°, or 

 what some obstetrists know as quarter torsion. If the torsion 

 continues until the uterus has made a complete revolution upon 

 its long axis, it is known as complete torsion. Some writers 

 would have us believe that the uterus may make four complete 

 revolutions. This assumption or statement is open to question. 

 It cannot well go very far beyond a complete revolution, until 

 the strain upon the organ becomes too great, and it twists oflF or 

 ruptures transversely and drops, an inert bag, into the abdominal 

 cavity.
