The pubic arch is part of the pelvis. It is formed by the convergence of the inferior rami of the ischium and pubis on either side, below the pubic symphysis. The angle at which they converge is known as the subpubic angle.^[1]

Function

The pubic arch is one of three notches (the one in front) that separated the eminences of the lower circumference of the true pelvis.^{[citation needed]}

Clinical significance

Subpubic angle

The subpubic angle (or pubic angle) is the angle in the human body formed at pubic arch by the convergence of the inferior rami of the ischium and pubis on either side. The subpubic angle is important in forensic anthropology, in determining the sex of someone from skeletal remains. A subpubic angle of 50-82 degrees indicates a male; an angle of 90 degrees indicates a female.^[2] Women have wider hips - a greater subpubic angle - in order to allow for child birth. Other sources operates with 50-60 degrees for males and 70-90 degrees in females.^[1]

As seen in the picture , there is a distinctive difference between the pubic arch of a male and a female. This difference is found in the subpubic angle. The area in which the pubic arch is located is the pelvis, the area that is most different between male and female anatomy. The subpubic angle of a man is generally 50-60 degrees while that of a woman is generally 70-90 degrees.^[1] The reason for this difference has to do with childbirth. A woman’s pubic arch is wider in order to allow for the passage of the child during birth. The pelvic inlet of a female is also wider because the child’s head must pass through it. The pubic arch is also referred to as the ischiopubic arch.
