Purpose: Fetal arthrogryposis multiplex congenita (AMC) describes a heterogeneous disease entity characterized by multiple contractures affecting at least two different body areas. The aim of our study was to identify additional sonographic abnormalities in fetuses with AMC Type I-III associated with an unfavorable prognosis and to describe when those signs were first detected.
Methods: This retrospective study included 41 pregnancies of suspected AMC diagnosed 1999-2017 at our tertiary referral center.
