The pubic arch, also referred to as the ischiopubic 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.{{cite book |last=Bojsen-Møller |first=Finn|last2=Simonsen |first2=Erik B. |last3=Tranum-Jensen |first3=Jørgen| year=2001 |title=Bevægeapparatets anatomi |edition=12th |language=Danish |trans-title=Anatomy of the Locomotive Apparatus | isbn =978-87-628-0307-7|pages=257–258}}

Function

The pubic arch is one of three notches (the one in front) that separate the eminences of the lower circumference of the true pelvis.{{Citation needed|date=May 2013}}

Clinical significance

=Subpubic angle=

The subpubic angle (or pubic angle) is the angle in the human body as the apex of the pubic arch, formed 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.Anthony J. Bertino. Forensic Science - Fundamentals and Investigations. South-Western Cengage Learning, 2000. {{ISBN|978-0-538-44586-3}}. Page 368 Other sources operate with 50–60 degrees for males and 70–90 degrees in females. Women have wider hips, and thus a greater subpubic angle, in order to allow for child birth.
