Inflammatory diseases, such as ankylosing spondylitis, result in bony fusion of the symphysis. Osteitis pubis, the most common inflammatory disease in this area, is treated with anti-inflammatory medication and rest. Degenerative joint disease of the symphysis, which can cause groin pain, results from instability or from abnormal pelvic mechanics. Symphysiolysis is separation or slipping of the symphysis. It has been estimated to occur in 0.2% of pregnancies. Pregnancy
During pregnancy in the human, hormones such as relaxin remodel this ligamentous capsule allowing the pelvic bones to be more flexible for delivery. The gap of the symphysis pubis, normally is 4–5 mm but during pregnancy there will be an increase of at least 2–3 mm, therefore, it is considered that a total width of up to 9 mm between the two bones is normal for a pregnant woman. The symphysis pubis separates to some degree during childbirth. In some women this separation can become a diastasis of the symphysis pubis. The diastasis could be the result of a rapid birth, or a forceps delivery, or may be a prenatal condition. A diastasis of the symphysis pubis is a cause of pelvic girdle pain (PGP). Overall, about 45% of all pregnant women and 25% of all women postpartum suffer from PGP. Symphysiotomy
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. It allows the safe delivery of the fetus where Caesarean section is not an option.
Pinch marks are a cutaneous condition, and when on the ears or in the genital region of male children may be suggestive of child abuse. See also
