Shoulder Dystocia by Severity in Families: A Nationwide Population Study

( Acta Obstet Gynecol Scand . 2024;103(10):1955–1964. doi:10.1111/aogs.14766) Shoulder dystocia (SD) is a serious problem during childbirth that is connected to significant risks for newborns, such as brachial plexus injury, fractures, cerebral palsy, and perinatal death. The occurrence varies from 0.13% to 3.0%, and reoccurrence rates range from 7.3% to 13.5%. Important risk factors consist of considerable birth weight (risk grows more than 50 times for weights >4500 g), maternal diabetes, previous SD, assisted delivery, and labor dystocia. Research indicates that severe instances of SD have a greater likelihood of happening again, but there has not been enough research done on how severity affects recurrence and intergenerational transmission.
