In a certain proportion of cases the knee-chest position alone will not dislodge the retroflected uterus, so that manual aid is required to effect that purpose. There is a number of methods that have been suggested from time to time, but none are so good as that in which the knee-chest position is combined with the manipulation of the operator. Reposition may occur spontaneously, and it undoubtedly does in a large proportion of cases, in which the retroflected organ becomes pregnant. When the retroflected organ occasions symptoms of retention of urine, the bladder should first be emptied with a soft No. 8 catheter, then the patient is directed to kneel on both of her knees, her thighs remaining perpendicular, while her body inclines forward until one or the other shoulder touches the floor or level of her knees. The operator may then gradually lift the womb and elevate the body sufficiently so that it will fall forward into its natural place. When there is no bladder trouble from compression, and the womb resists even mild force to replace it, I have accomplished gradual reposition by keeping the woman in bed for three or four weeks, with the instructions that she resume the knee-shoulder position two or three times a day, and from five to ten minutes, also that she shall lie on her side and chest and never on her back. In this manner I have accomplished in time and without force what could not have been accomplished with forcible attempts without inducing an abortion. It curiously happens that there are cases of retroflection which are never suspected nor recognized until the patient has become pregnant. After the woman is about three months gone, the growth of the pregnant uterus can no longer be accommodated in the pelvis, because the direction of its growth is in the direction of the retroflected organ, namely, backwards and downwards (see Plate IV) which makes it a physical impossibility to escape from or grow out of the bony pelvis. The symptoms are retention of urine or a constant dribbling of urine and a straining at stool or pain in the rectum or pelvis, and, of course, the absence of the menses since the commencement of pregnancy. Retroflection may be also acquired during the first three or four months of normal pregnancy, from a jump or fall on the back, in which all the symptoms that indicate this condition are suddenly manifested. In pregnancy, the course that is to be pursued, in order to rectify the displacement, must be obviously different from that pursued when the woman is not pregnant. The pregnant uterus is a “touch me not;” it permits of no tampering without running the fearful risk of inducing an abortion, and no one but a tyro or an ignoramus will ever meddle with the pregnant womb.
