Pubic symphysis

The pubic symphysis or symphysis pubis (Latin: symphysis pubica) is a secondary cartilaginous joint of the pelvis located between the two pubic bones. Usually, there are no or minimal movements in the pubic symphysis, except during pregnancy and childbirth.

The pubic symphysis is located between the symphyseal surfaces of the left and right pubic bones. Between both surfaces is a fibrous cartilage formation called the interpubic disc. The pubic symphysis is strengthened by two ligaments - superior and inferior pubic ligaments.

The superior pubic ligament stretches above the symphysis between both pubic tubercles. The inferior pubic ligament extends below the symphysis and connects the left and right inferior pubic rami. The inferior pubic ligament is also known as the arcuate pubic ligament.
