The distance between thefemoral trochanters may be obtained by placing each point as nearly aspossible upon the most projecting part of each greater trochanter. This lastis an unimportant diameter. In external pelvimetry we rely upon the fol-lowing twelve measurements; the first four of which are most commonlyused: (i) Interspinous. (2) Intercristal. (3) Between the great trochanters.(4) The external conjugate, or Baudelocques diameter. (5) Right obliquediameter. (6) Left obUque diameter. (7) Between the posterior superioriliac spines. (8) Between the tub era ischii. (9) Transverse diameter of outlet.(10) Antero-posterior diameter of outlet. (11) Length of the symphysis.(12) Circumference of the pelvis. (13) True conjugate measured Fig. 202.—Schultzes METER. Pelvi- THE EXAMINATION OF PREGNANCY. 163 1. Interspinous Diameter (Fig. 203).—This is the widest distance betweenthe anterior superior ihac spines, and is measured by placing the points of thepelvimeter upon the external surfaces of the spines, at the insertion of the sar-torius muscles (Fig. 203). In normal pelves this measurement varies from9^ to 10^ inches ( to cm.). 2. Intercristal Diameter (Figs. 203 and 204).—This is the widest interval A/f/erior
