    LIGAMENTS OF THE PELVIS. Connected with the pelvis there are several ligaments, but in an obstetric view, the ligaments which alone are of importance, are the obturatores, and more especially the sacro-ischiatic liga- ments, With the ligaments of Poupart and Gimbernat the accoucheur has very little to do. Obturator* Ligaments :—The obturator ligament} is the ligamentous sheet which closes the obturator foramen, having an aperture at the upper and back part, through which the obturator artery, vein, and nerve, are transmitted. To the obstetrician the vein is not of much consequence, but the artery and nerve are of considerable interest, particularly the latter, as the trunk of it is liable to be compressed and injured under the foetal head. Sacro-Ischiatic Ligaments :—Are a set of ligaments lying on the sides of the pelvis, and somewhat behind. They are divided into two pairs; the one lying externally, the other within, and hence the appellation of the ewvternal and internal. The external sacro-ischiatic ligament,£ arises strong and narrow from the tuberosity of the ischium, passes outwards, backwards, and upwards, becoming very broad, to be inserted into the lower part of the sacrum and the upper part of the os coccygis. The internal ligament§ arises narrow and strong from the ischial spine, passes upwards and backwards, to be inserted broadly into the lower part of the sacrum and the upper part of the os coecygis, laterally, much in manner like the former. JOINTS OF THE PELVIS. The joints of the pelvis are those of the hip, the lumbar, the sacro-schiatic, the sacro-caccygeal, the sacro-iliac, together * Obturator:—From obtwratus, closed, stopped up; wherefore oltwrator signifies a stopper up, which effect the obturator muscles and ligaments have as regards the obturator foramen... t Hi Fig. le Pps 10, } M, Fig. ie Pp. 10. § L, Fig. 1, Pp. 12.
