Amniotic bands are caused by tearing of amnion, which produces fiber like bands that may entrap the fetal parts in utero, a condition called Amniotic band syndrome (ABS). As the baby grows, the bands constrict or tighten, causing a reduction in blood supply and the extremities may develop abnormally or become amputated.
