It is placed upon the anterior pubic border, exactly in the middle, an assistant driving it with light blows from a wooden mallet. The pelvis may also be divided with Hinze's saw. After separation has been effected one way or the other, the obstetrician draws the loop of a cord along the lower side through the oval foramen and then along the outside of the ilium back; the free end of the rope is put through the loop, pushing it over that portion of the pelvis with the thumb and index fiuger. Now an assistant may extract that half of the pelvis (fig. 68). The other half of the pelvis may be removed similarly. The head of the femur p- gg can now be plainly felt. The muscles around the upper portion of the thigh are severed with the hand and a loop placed below the trochanter. An assistant pulling on the rope, vigorously, can bring it into the parturient passage. As soon as its superior extremity passes into the pelvis the other hind leg enters also and parturition is at an end. EMBEYOTOMY IN THE POSTERIOR PRESENTATION WITH BOTH HIND LEGS IN THE PELVIC CANAL. "When complete extraction is impossible in this position, one hind leg is removed subcutaneously,' as previously dis- cussed. By pulling now on the other hind leg, extraction of the calf is usually Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bruin, M.
