Complications.—There are usually a number of conditions compli-cating retroversions and retroflexions which must not be overlooked. Suchare, first, a prolapsus of the uterus of a moderate degree, due to the samecauses which produce retroversion,—namely, relaxation of the supports. 488 DISPLACEMENTS OF THE UTERUS.
