msk congenital

If this deformity were present at birth (and not sliced off by me or you), what would be the most likely etiology?

Amniotic Band Syndrome

1 per 3000 pregnancies

Floating amniotic bands ensnare a developing body part

Pressure from the bands may cause abnormalities distal to the constriction

Constriction bands across the face may lead to facial clefts
