SYMPTOMS AND COURSE.--Among the most pronounced symptoms are profuse uterine catarrh, menstrual disorders, sterility, abortion, weakness, pain in the back, painful defecation, rectal tenesmus, the symptoms of pelvic inflammation, neurasthenia, and other nervous symptoms. The uterine catarrh is due to an effort on the part of the engorged pelvic organs to relieve themselves by an exaggerated secretion of mucus from the uterus, which upon being increased in quantity becomes vitiated in quality, and therefore pathological. Menorrhagia and abortion may also result from congestion. Dysmenorrhoea and sterility result from the {168} general anæmic condition and from the inflammatory complications, and from the obstruction in the uterine canal or in the blood-vessels at the angle of flexure. (See Pathology of Anteflexion.) The rectal symptoms are caused by the pressure of the corpus uteri upon the rectum, which gives the sensation to the patient of an overloaded bowel. Should pregnancy occur, the rapid growth of the uterus may induce spontaneous reposition at about the fourth month, when the fundus rises out of the pelvis, but if the corpus be incarcerated under the sacral promontory from adhesions or from any other cause, the uterus will, unless manually replaced, relieve itself by abortion. Abdominal pains, nervous dyspepsia, and neuralgia in distant parts of the body are often present; indeed, the nervous symptoms may be of the most exaggerated character, and may comprise all that is implied by the word hysteria in its most comprehensive signification. DIAGNOSIS.--Digital touch discloses the cervix low in the pelvis, and the fundus uteri is felt through the posterior vaginal wall in the cul-de-sac of Douglas. Conjoined manipulation with the index finger of the left hand, first in the vagina and then in the rectum, and the right hand over the hypogastric region, will show the size, form, consistency, and location of the uterus, the degree of the flexure, and the difficulty of replacement. An inflammatory exudate or hæmatocele, posterior to the uterus, or a fibroid in the posterior uterine wall, may be mistaken for the retroflexed corpus. The probe will always verify the diagnosis, but if there be great tenderness with fixation in the cul-de-sac of Douglas, treatment should be directed against the inflamed condition, and the final diagnosis made by repeated examinations or after the disappearance of the inflammation. Great and lasting injury is often done in the attempt to complete the diagnosis at the first examination. The presence of a fibroid in the posterior uterine wall with post-uterine inflammation is a serious complication both in diagnosis and treatment. If the rectum be overloaded with fecal matter, the diagnosis should be deferred. The displacement is distinguished from the presence of an ovary or small ovarian tumor in the pouch of Douglas by careful bimanual examination and by the probe.
