Annular constrictions around the digits, limbs, or trunk, occurring congenitally (sometimes causing intrauterine autoamputation) and also associated with a wide variety of disorders. Constrictive amniotic bands are the result of primary amniotic rupture, which can lead to entanglement of fetal tissue (especially limbs) in fibrous amniotic strands.
