Abstract：
:The blood supply of the symphysis pubis is still the subject of some debate. Classic anatomy books state that this joint is avascular, whereas some published works have shown blood vessels in young specimens. As several articular discs such as the knee menisci are known to have blood vessels in their peripheries, we decided to investigate the possible nutrition pathways to the interpubic disc and ligaments. We used 60 Wistar rats, male and female, aged between 28 and 32 days, or between 90 and 100 days. Samples were processed using a variety of techniques: regular histology, immunohistochemestry, India ink injection and corrosion casting. The interpubic disc consisted of an inner bearing portion and an outer fibrous rim. The interpubic ligaments and the fibrous rim were well vascularized in all groups. Marrow contacts between the interpubic disc and the subchondral bone were also observed. Blood vessels formed an authentic arterial circle embracing the joint, from which blood vessels branched into capillary loops facing the avascular inner bearing portion of the disc. These results confirm the need for future studies on the human symphysis pubis, to provide more details on its structure, which would enable clinicians such as physiotherapists to improve prognosis and treatment design. Future studies may also explain the pathways down which the hormone relaxin reaches its targets within this joint.
