  • The pelvic inlet, or the upper pelvic narrow, is the anatomical limit between the true pelvis below and the false pelvis above. There are tangible, genetic and hormonal differences between the male and female pelvis related to the reproductive function. In obstetrics, the pelvic inlet is the entrance door toward the birth canal. The fetal cephalic extremity needs to position itself and to adapt a…
  • Which Foetal-Pelvic Variables Are Useful for Predicting Caesarean Section and Instrumental Assistance? [Journal Article]
    Med Princ Pract 2017; 26(4):359-367Frémondière P, Thollon L, … Marchal F
  • CONCLUSIONS: The antero-posterior inlet was an efficient variable unlike the obstetric conjugate. The obstetric conjugate diameter should no longer be considered a useful variable in estimating the arrest of labour. Antero-posterior inlet diameter was a sagittal variable that should be taken into account. The comparison of sub-pubic angle and bi-parietal and antero-posterior outlet diameters was useful in identifying a risk of requiring instrumental assistance.
  • Pelvimetry by Three-Dimensional Computed Tomography in Non-Pregnant Multiparous Women Who Delivered Vaginally. [Journal Article]
    Pol J Radiol 2016; 81:219-27Salk I, Cetin A, … Cetin M
  • CONCLUSIONS: The findings of this study present the reference values of the main planes of the true pelvis by 3D CT pelvimetry in a relatively large group of multiparous women who passed a trial of labor successfully. Overall, the pelvises had features of female pelvic bony structure although pelvic diameters were somewhat lower in multiparous women with short stature. The 3D pelvimetry with CT applications may be used as an adjunct to clinical and ultrasonographic examinations to rule out cephalopelvic dystocia in selected cases.
