The replacement of the retroflected uterus, that is positively not pregnant, and there must be no question about it either, will admit of introducing a sound into its cavity. This sound is used as a lever upon which the organ may be lifted out of its abnormal position and inclined over the bladder in an anteflected position, which is its natural one. The sound which I employ, and which is my own invention, for replacing the uterus is screwed into a thimble, and from two and one-half to three inches long. The object of this is to artificially elongate the finger so that it can be introduced into the womb. The force which one employs by using this instrument is keenly appreciated by the operator, hence there can be no undue strain, that otherwise might be exerted on adhesions which are too strong to be safely lacerated or even stretched, while slight and recent adhesions might be torn without any bad results. Truax, of Chicago, manufactures my repositor. Before introducing any sound into the uterine cavity, it is absolutely necessary that the vagina should be thoroughly cleansed with borax water. The inflammatory enlargements of the womb, subinvolutions, uterine catarrhs, and any of the complications that may exist at the time that the organ is replaced, should be treated on the same principles that have been laid down in the respective chapters on these diseases; in fact, these complications constitute part of the after treatment for retroversion or flexion. The other treatment is to be directed toward retaining the womb where it naturally belongs. The daily exercise in the knee-chest position should never be neglected, and in cases in which this is insufficient, it is very probable that the pelvic floor or natural support of the uterus has been injured or lacerated during confinement, and this may require a plastic operation as a preliminary to a cure. In obstinate cases there is no cure so effectual as pregnancy and a full-time delivery, provided precautions are taken so that the mother will not acquire a new retroflexion during her lying-in period, from the cause that has been already detailed. The patient must accustom herself to sleep either on the chest with face turned to one or the other side, or in a semi-prone position on either the right or left side. Perseverance in sleeping in this manner for a few weeks cultivates the habit that gives more refreshing sleep than lying on the back, which most persons are inclined to do. CHAPTER XXI. DISEASES OF THE FALLOPIAN TUBES. THE Fallopian tubes are the ovi ducts, along which the spermatozoids pass from the womb to fertilize the ovum, and along which the fertilized or non-fertilized ovum, as the case may be, is carried to the cavity of the uterus. They are two small canals, between three and a half and four inches in length, and constitute the only means of communication between the womb and ovaries; their caliber is exceedingly small and lined with a delicate mucous membrane.
