The pubic symphysis is a nonsynovial amphiarthrodial joint. 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.

Symphysiotomy is a surgical procedure in which the cartilage of the pubic symphysis is divided to widen the pelvis allowing childbirth when there is a mechanical problem (obstructed labour). It is also known as pelviotomy [ 1 ] and synchondrotomy. [ 1 ]
Symphysis pubis dysfunction (SPD), commonly known as pubic symphysis dysfunction or lightning crotch, [1] is a condition that causes excessive movement of the pubic symphysis, either anterior or lateral, as well as associated pain, possibly because of a misalignment of the pelvis.
A symphysis (/ ˈ s ɪ m. f ɪ. s ɪ s /, pl.: symphyses [1]) is a fibrocartilaginous fusion between two bones. It is a type of cartilaginous joint, specifically a secondary cartilaginous joint. A symphysis is an amphiarthrosis, a slightly movable joint. A growing together of parts or structures. Unlike synchondroses, symphyses are permanent. [2]
In human anatomy, and in mammals in general, the mons pubis or pubic mound (also known simply as the mons / m ɒ n z /, and known specifically in females as the mons Venus or mons veneris) [1] [2] is a rounded mass of fatty tissue found over the pubic symphysis of the pubic bones.
Pubic symphysis diastasis (also known as diastasis symphysis pubis) is the separation of normally joined pubic bones, as in the dislocation of the bones, without a fracture that measures radiologically more than 10 mm. Separation of the symphysis pubis is a rare pathology associated with childbirth and has an incidence of 1 in 300 to 1 in 30,000 births.
The pubic bone is made up of a body, superior ramus, and inferior ramus (Latin: branch). The left and right coxal bones join at the pubic symphysis. It is covered by a layer of fat – the mons pubis. The pubis is the lower limit of the suprapubic region. In the female, the pubis is anterior to the urethral sponge.
The retropubic space is a surgical landmark that has surgical significance in several gynecological and urological procedures. Access to the space is achieved by separating the rectus abdominis muscle at the mid line, and bluntly dissecting the tissue in the direction of the symphysis pubis, until reaching the peritoneum.
