The iliopectineal line is the border of the iliopubic eminence. It can be defined as a compound structure of the arcuate line
(from the ilium) and pectineal line
(from the pubis). With the sacral promontory
, it makes up the linea terminalis
.
The Iliopectineal line divides the pelvis into the pelvis major (false pelvis) above and the pelvis minor (true pelvis) below.
