Structure
The pubic symphysis is a secondary cartilaginous joint that consists of a fibrocartilaginous interpubic disc that lies between the symphyseal surfaces of the bodies of the right and left pubic bones. This joint is reinforced by the superior and inferior pubic ligaments. The articular surfaces of the pubic bones are coated with a thin layer of hyaline cartilage to which the fibrocartilaginous disc connects the two pubic bones.
Anatomical Relations
Anterior to the pubic symphysis is the proximal shaft of the penis or the clitoris. In both sexes, the bladder is posterior to the upper portion of the joint and the urethra passes inferiorly.
Function
The pubic symphysis permits slight movements but primarily serves to connect the left and right ox coxae and provide stability to the pelvic girdle. It also provides protection and support to the bladder which lies posterior to it and helps to support the attachment of the clitoris (females) and the penis (males).
