Dystokia in the Anterior Presentation due to the Forward Extension of the Hind Limbs Beneath the Fetal Body. In the mare, and possibly in other animals, we occasionallyencounter a fetus presenting anteriorly, with the anterior limbsand head in an approximately normal position, and the twoposterior limbs thrust forward in extreme extension beneath thebody of the fetus, so that the two hind feet are lodged just infront of the maternal pubic brim, or have passed some distancealong the pelvic canal. This places the fetal body in such aposition that its progress becomes blocked when the neck or chesthas appeared at the Fig [34. Forward Deviation ok Posterior LimbsIN Anterior Presentation. (St. Cyr.) The nature of this presentation suggests to one that of theventral transverse presentation, in which all four feet are present,but the head is wanting, whereas in this case all four feet andthe head offer at the inlet, and become more or less engaged in it. The fetus is ordinarily in the dorso-sacral position, with theproper relations existing between the two anterior limbs and thehead and neck. However, when it has advanced sufficiently forthe fore feet and nose to show at the vuKa, its further progressbecomes blocked. the hand beneath the body of thefetus, the operator encounters one or both posterior feet, either inthe pelvic canal or just anterior to the brim of the pubis, wherethey are easily recognized, their soles directed downwards. Thespinal column is jammed hard against the maternal sacrum. Forward
