1. Pseudo or temporary paralysis of the anterior crural occurs, complicating pregnancy.
2. The paralysis appears to be due to pressure upon the nerve before it divides into the anterior and posterior branches, as manifested by paralysis of the entire motor distribution. (There was no disturbance in sensation.)
3. The occurrence, we believe, is probably incident to an abnormal position of the nerve in its pelvic relations.
4. Age and physical conditions did not appear to enter into the etiology. Both patients were well nourished and developed, the younger being twenty-six, the elder thirty-nine.
5. No permanent disability was observed. The duration of the paralysis may be from a few hours to several months.
6. Mild transient types of cases most certainly occur, their presence being overlooked or considered a post-delivery incidence rather than a complication of labor.
7. Cases may be divided into pseudo partial and pseudo total, depending upon the point of pressure.
8. Primary separation of the symphysis articulation occurs, permitting the head to occupy a position low in the pelvis.
9. The severe pain in the symphysis pubis is due to two things: first—early separation of the symphysis articulation, resulting in an inflammatory lesion of the normal synovia; second—irritation of the sensory portion of the genito crural nerve from pressure.
