244 BOVINE OBSTETRICS 



head may be brought upon the fore legs either with the hand 

 or by cording the lower jaw. Should a small, blunt hook, to 

 which a rope is attached, be inserted into the orbital cavity, it 

 should be covered by the hand to prevent injury should it give 

 way. Only one man must pull on the hook. 



When all the foetal waters are discharged, an infusion of a 

 large amount of warm water must first be administered, before 

 reposition is attempted, this procedure rendering it much 

 easier (Franck-Gbring). 



Should reposition be impossible, one or two fore legs are 

 removed subcutaneously, thus gaining sufficient room to reach 

 the head. The obstetrician should know the exact state of 

 affairs, especially in this abnormal presentation, and take care 

 that traction is not exerted on the head with a rope passed on 

 the outside of the legs. One usually rejoices when the lower 

 jaw is corded, and forgets that the head must be drawn up be- 

 tween the fore limbs. After pulling repeatedly and without 

 success, the idea suddenly strikes us to pull in the right direc- 

 tion — that is, between the fore legs — and to repel the calf at 

 the same time. 



The head turned backward and upward. 



This malposition is not often met with in the calf. The 

 slow rotation and the short neck prevent it toi"^. certain extent. 



Diagnosis. — The fore legs lie in the vagina, the tracheal 

 portion of the neck opposite the pelvic inlet, the lower jaw 

 against the rectum. The best guides are the larynx and tracLse 

 of the foetus. The short neck always renders the head ac- 

 cessible. 



Prognosis. — When the examination reveals that the supe- 

 rior vaginal wall is not injured by previous manipulations, 

 prognosis is favorable. 



Treatment. — Reposition by hand is possible in many in- 

 stances. For this purpose the lower jaw is grasped by the 

 fingers and an assistant repels the calf by the fore legs. Now, 

 by drawing the hand toward the vulva, the head enters the 

 pelvic canal; a loop may also be placed around the inferior
