16 i BOVINE OBSTETRICS 



on her back. As a rule, calf and uterus rotate at the same 

 time. Now I endeavor to render the calf immovable ; the cow 

 is quickly rolled back onto the left side and allowed to rise. 

 In some cases detorsion is obtained provided the hindquarters 

 are well elevated. 



Any doubts regarding the direction of the torsion are 

 easily dispelled by rolling the cow. When the vaginal constric- 

 tion increases or decreases by rotation, the rolling in the first 

 instance is in the wrong direction and in the latter in the right 

 direction. Beginners may in this manner confirm their diag- 

 nosis. 



For this purpose the cow is placed upon the right side, the 

 fore and hind legs tied separately, the posterior extremities 

 being raised. The right hand in the vagina follows the folds, 

 while the cow is rolled on her back and then slowly on the left 

 side. Any increased pressure upon the hand and arm after 

 such a rotation shows at once that the cow is rolled in the 

 wrong direction and that rotation is to be practiced in the 

 opposite direction. 



Guillod states that the obstetrician should roll over instead 

 of the cow. By following the spirals with the hand and roll- 

 ing from the abdomen upon the back, the uterus may be 

 entered. His method was effective in ten cases where he 

 rotated the cow in vain. 



Rotation of the cow is one of the oldest methods and was 

 mentioned already by Eychner in his "Bnjatrik." 



Another method of treatment consists in rotation of the 

 uterus and calf. The cow may be left in the standing or recum- 

 bent posture. In this method detorsion is either practiced 

 from the vagina or uterus, or by first performing laparotomy. 



DETORSION FROM THE VAGINA AND UTERUS. 



This method has many advantages over rotation of the 

 mother. It may be executed in two ways : in the standing and 

 recumbent position of the animal. But I wish to emphasize 

 the fact, that this method can only be successful when the hand 

 can enter the uterus ; that is, in torsions of 90 degrees to 180
