It is jn-edisposed to by a rigidOS, faulty presentation or condition of the foetus, premature ruptureof the membranes and previous disease of the cervix. What is the pathology ? The laceration may be— 1. Complete. Penetrating the whole thickness of the cemx. 2. Partial. Including cervical mucous membrane, but not ap- pearing on the vaginal surface. It may be— (a) Unilateral (see Fig. 40). (5) Bilateral. (c) Stellate (see Fig. 41).The unilateral laceration is most apt to occur in the line of the Fig. Single Laceration. The flaps are held apart with a double tenaculum {Emmet), right oblique diameter of the pelvis; i. e., either anteriorly and tothe left or posteriorly and to the right, especially the former. Thisis supposed to arise from the greater frequency of the first positionof the vertex. Bilateral lacerations are usually more dangerous than those of theanterior or posterior lip, because ojDening up the cellular tissue of thebroad ligaments. Stellate lacerations are more apt to be superficial. If the surfaces of laceration are kept clean, more or less union LACERATION OF THE CERVIX. 165 will occur. Usually there is partial union, with eversion and pro-liferation of the cemcal mucous membrane, hyperplasia of the con-nective tissue and proliferation of the glandular structure.
