Excessive flexion of the head upon the trunk has been termed Roederersobliquity (Fig. 638). This is nothing more than an exaggeration of the normalhead flexion of labor whereby the occiput enters the inlet perpendicularly, the 499 500 PATHOLOGICAL LABOR. EXCESSIVE FLEXION OF Fig. head moulding being more to the posterior part of the head, with the apex wellback on the occipital bone, thus positively providing for the engagement of thesuboccipito-bregmatic circumference, ii inches (28 cm.), in the circumferenceof the inlet, 16 inches ( cm.), and is to be looked upon as a favorable condi-tion. The causes are excessive rigidity of the cervix or vagina, generally con-tracted pelvic inlets, or excessively largefetal heads, especially in dead or macer-ated fetuses. The diagnosis is simple. Inleft positions of the head the small fon-tanelle is more to the right and very littleof the sagittal suture can be felt; the largefontanelle is unusually high. The prognosisis not necessarily favorable at the pelvicinlet, although after the engagement of thehead the conditions never cause of the obstruction sometimes pro-duced at the inlet by excessive flexion o
