In _antiflexion_ we find the fundus pressing upon the bladder. These displacements are rare in virgins. The false membrane formed in peritonitis is now and then the cause of these deviations, when there is superadded such causes as are mentioned for prolapsis. The symptoms of RETROFLEXION are usually a dull, weary and constant backache, which is more marked about the sacral region, pains that shoot down the thighs or the groins, and a frequent desire to go to stool, although nothing comes away. The passage of a motion that is not at all constipated aggravates the pain and aching; sexual intercourse is attended with suffering, and is not followed by pregnancy; and just before and after the monthly periods there is so much tenderness that sexual connection cannot be tolerated. [Illustration: Fig. 15. Antiflexion of the uterus. ] The catamenia come on with pain and difficulty, but about the second day the flow of blood seems to give some relief. The general health is bad, there are frequent attacks of nausea, the appetite is small, the spirits are depressed, and there are many what are called hysterical symptoms. On examination the congested fundus may be found encroaching upon the rectum; on touching this part the patient will exclaim that it is the seat of her sufferings, and it is not uncommon to find tenderness of one or both ovaries. Not many of these symptoms are present in ANTIFLEXION, but this commonly produces great irritability of the bladder, so that when the patient is in the erect position, the desire to micturate is almost as great as in disease of the bladder. [Illustration: Fig. 16. Anteversion of the uterus. ] The treatment includes replacing the uterus with the sound. Should there be adhesions, however, this might cause intolerable pain. In such cases relief is given by the use of belladonna plasters and belladonna, opium, hyoscyamus, or conium tampons. One-half to one dram of the tincture of one of the narcotics may be added to the glycerine in which the tampon is soaked, or the cervical end of the tampon may be dipped in the tincture. Suppositories and ointments may also be used. (F. 163, 214). RETROVERSION AND ANTEVERSION. In RETROVERSION (Fig. 13) the fundus is turned toward the hollow of the sacrum, while the os is drawn under the arch of the pubis.
