title: Birth trauma to muscles in babies born by breech delivery and its possible fatal consequences.
abstract: Dissection and histological examination was made of the muscles of 86 babies who died after breech delivery, and of 38 babies who died after vertex presentation. A control group of 50 surviving breech-delivered babies was examined clinically and the results compared. It was concluded that the most common type of birth trauma to a baby born by breech delivery is injury to muscles and soft tissues of the back and lower extremities, which is often extensive. In some severly injured babies histological examination of organs revels signs of crush syndrome and disseminated intravascular coagulation. It is suggested that the extensive muscle trauma forms the background of these fatal conditions.
