Amputation of the Head.

Amputation of the Head.
The lamb is in anterior presentation, in a dorso-sacral position, with an abnormal posture. Both front legs are retained at the shoulders. If the lamb is dead, amputation of the head creates room for manipulation. The neck of the lamb is subsequently repelled into the uterus to facilitate extending one or both of the front limbs to permit extraction.
