Mechanism and Course of Labor.—We may say there is practically no mech-anism of labor in shoulder presentation. It is safer to look upon labor as im-possible without artificial aid than to trust to a spontaneous termination of thecomplication. The usual steps in unaided cases are impaction of the shoulder;ascension of the contraction ring; fetal death from prolonged pressure andmaternal death from rupture of the uterus or exhaustion. While this is true,still under certain conditions a shoulder presentation has been known to terminate F-iG. 737.—At the Pelvic Fig. 738.—At the Pelvic Inlet. fi Fig. -RiGHT Shoulder in the Cer-vix.
