The pubic symphysis is a nonsynovial amphiarthrodial joint. The name comes from the Greek word "symphysis '', meaning "growing together ''. The width of the pubic symphysis at the front is 3 -- 5 mm greater than its width at the back. This joint is connected by fibrocartilage and may contain a fluid - filled cavity; the center is avascular, possibly due to the nature of the compressive forces passing through this joint, which may lead to harmful vascular disease. The ends of both pubic bones are covered by a thin layer of hyaline cartilage attached to the fibrocartilage. The fibrocartilaginous disk is reinforced by a series of ligaments. These ligaments cling to the fibrocartilaginous disk to the point that fibers intermix with it.
