Amniotic constriction ring (HP:0009775)help
Term ID: 9775
Name: Amniotic constriction ring
Synonym: Amniotic bands; Amniotic constriction band; Congenital constriction band sequence; Pseudoainhum
Definition: 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.
