Pelvimetry among normal, healthy females using three-dimensional computed tomography in Sohag population: A retrospective Morphometric study regarding age

Abstract

Background: Measurements of the pelvic planes become essential to be described nowadays, so that obstetricians become able to describe and diagnose cases of a narrow pelvis and decide a cesarean section correctly, comparison of these parameters with other populations is very important as well as associate any changes with age. Objectives: is to evaluate the pelvic inlet and outlet parameters among normal, healthy non-pregnant reproductive-aged females and compare between younger and older ones in Sohag Government. Patients and Methods: The study was done on the archived information of Departments of Diagnostic Radiology, Sohag Faculty of Medicine, Sohag University, in Upper Egypt on 110 female patients from 18 to 55 years old who underwent computed tomography (CT) between March 2022 to March 2023 and was grouped into younger and older according to age. Four measurements was taken on sagittal plane Anatomical conjugate diameter (ACD); Obstetric conjugate diameter (OCD); Diagonal conjugate diameter (DCD) and Anatomical anteroposterior diameter of the pelvic outlet (AD) plus the Bituberous diameter (BD) on the coronal plane. Results The mean Anatomical conjugate diameter (ACD) was 11.4 ±1.03 cm, Obstetric conjugate diameter (OCD) was 10.9±1.06 cm, Diagonal conjugate diameter (DCD) was 12.4± .9 cm, Anatomical anteroposterior diameter of the pelvic outlet (AD) was 9.67 ±1.25 cm, Bituberous diameter (BD) was 10.74±.89 cm Non-significant changes appeared between the two age groups as regards the five measured parameters. Conclusion: No-significant differences was found between younger and older females as regarding inlet and outlet pelvic parameters
