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 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.

Pubic symphysis diastasis is an extremely rare complication that occurs in women who are giving birth. Separation of the two pubic bones during delivery at the symphyseal joint is extremely rare. Typically, during the birthing process, there is a sound that can be heard by the human ear to detect that there could be a case of symphyseal diastasis.
The treatment of obstructed labour may require cesarean section or vacuum extraction with possible surgical opening of the symphysis pubis. [4] Caesarean section is an invasive method but is often the only method that will save the lives of both the mother and the infant. [18] Symphysiotomy is the surgical opening of the symphysis pubis.
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 ]
In pathology, diastasis is the separation of parts of the body that are normally joined, such as the separation of certain abdominal muscles during pregnancy, or of adjacent bones without fracture. [ 1 ]
The pubic symphysis has a fibrocartilage joint which may contain a fluid filled cavity and is avascular; it is supported by the superior and arcuate ligaments. The sacroiliac joints are synovial, but their movement is restricted throughout life and they are progressively obliterated by adhesions. The nature of the bony pelvic ring with its ...
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.
