Ischiopubic Symphysiotomy 1.

Ischiopubic Symphysiotomy 1.
A pubic symphysiotomy is performed under epidural anesthesia in the standing heifer. A 6 to 8 cm skin incision is made on the midline about 5 cm below the lower commisure of the vulva, where the bony V of the ischia can be palpated. The incision is made through the subcutaneous tissues down to the bone. Ischiopublic symphysiotomies are indicated in primiparous heifers only, in which the pubic symphysis has not yet (completely) ossified.
