Microcephaly is diagnosed when the head circumference falls below 2 or 3 or even more standard deviations of the norm. It would have to be grossly abnormal and filled with fluid to effect head size, and that is something that you just cant miss on ultrasound. Brachycephaly is defined when the transverse diameter is greater than the AP (anterior posterior) diameter and the CI is > 86% (> 2 SD). to skeletal dysplasias to fetal triploidy (1). My OB said she could let me attempt to labor and have him naturally if I was insistent, as she knew my original plan was to have a vaginal birth with no epidural, but she didn't recommend it.

For bicorporeal uteri, the sensitivity was 83.3%, and the kappa was 0.900. If you look up shoulder dystocia it will give more comprehensive information. By comparing the growth one parameter with another, one may be alerted to a variety of fetal conditions ranging from IUGR to skeletal dysplasias to fetal triploidy (1). With multivariate regression, the three significant factors associated with shoulder dystocia were AC to HC 50 mm (odds ratio [OR], 7.3; confidence interval [CI], 1.6-33.3; p = 0.010), femur length (OR, 1.1; CI, 1.0-1.2; p = 0.002), and induced labor (OR, 1.8; CI, 1.1-3.1; p = 0.027).
