The malpositions are determined by excessive change in the inclination of the uterine axis. They are further divided into flexions, in which the organ is bent upon itself in an abnormal degree, manner, or direction; and versions, in which the axis of the unflexed uterus inclines in an abnormal degree or direction. The malpositions are retroversion, retroflexion, lateral version, lateral flexion, anteversion, anteflexion. SYMPTOMS AND DIAGNOSIS IN GENERAL.--Each variety of displacement may be indicated by its own group of symptoms and physical signs. These will be presented in the study of the special lesions. To avoid repetition, those symptoms and signs which pertain to no special displacement, but which belong to all alike, will be mentioned at once. They may arise either from the displacement itself or from its possible complications, of which the following are examples: Metritis, ovaritis, salpingitis, atresia and stenosis, cystitis, vesical catarrh, rectitis, rectal catarrh, peri-uterine cellulitis and peritonitis, uterine catarrh, tumors, cicatrices, etc. Uterine displacement may be a cause or an effect of associated complications, or together with them it may be a concurrent result of some common cause, or it may have had primarily no pathological connection with them. The symptoms of displacement refer to the pelvic organs or to the nervous system. Among the symptoms which refer to the pelvic organs are--difficulty in walking and standing; pelvic pain, more or less constant; dysmenorrhoea, menorrhagia, sterility, frequent abortion, constipation, painful or difficult defecation, dysuria, polyuria, tenesmus, etc. Among the symptoms which refer to the nervous system are--neuralgia in various parts, paralysis, hysteria, nervous dyspepsia, anæmia, chlorosis, spinal irritation, etc. The final diagnosis must always depend upon direct examination of the uterus itself. The first division of the above group of symptoms is not likely to escape notice as indicative of displacement, but the nervous symptoms are constantly disregarded or treated without reference to their possible pelvic origin. The frequent dependence of these nervous phenomena upon displacement is proved by their persistence in many cases after ordinary treatment, by their prompt disappearance upon permanent replacement and retention of the uterus by mechanical means, and by their equally prompt recurrence upon removal of the support. The presence, therefore, of the second division of the group or any part thereof, even though the first be absent, will justify, may even necessitate, a careful investigation into the state of the pelvic organs.
