Vertebrectomy is a type of obstetric dismemberment in which the fetal spine is severed to separate the fetus into two parts, each of which is then delivered vaginally. The purpose of obstetric dismemberment is to destroy or separate the fetal body so as to reduce the size of the fetus and facilitate its delivery from the vagina, and spinal dismemberment is one of these surgeries, which is performed by cutting the spine and separating the fetus into two parts to facilitate delivery, and the vagina must be carefully examined for damage after the delivery, especially to exclude rupture of the uterus. In modern obstetrics, due to the improvement of obstetrics technology and the strengthening of maternal and child health, fetal destruction due to obstructed labor is rarely used, and is usually used only for stillbirths, malformed fetuses, and so on.
