While such a policy has intuitive plausibility, it has been refuted by direct observation. Mathematic modeling of forces associated with shoulder dystocia: Stretching of the brachial plexus nerves by inappropriate physician traction Damage to the brachial plexus nerves despite appropriate traction and delivery maneuvers due to the intrinsic variation in the strength of nerve fibers between individual neonates i.
Definitions of macrosomia are not consistent, either in clinical practice or in the obstetrical literature. What causes brachial plexus injuries? In the Spong study, 60 seconds was found to be approximately two standard deviations above the mean value for head-to-body delivery time in uncomplicated shoulder dystocia deliveries.

As the most recent Dystovia bulletin on shoulder dystocia states, “Most cases of shoulder dystocia cannot be accurately predicted or prevented. Even if tools existed that allowed obstetricians to precisely determine fetal weight prior to delivery, the biologic variability of fetal shape, maternal pelvic dimensions, and the direction of forces in labor would make the predictability of shoulder dystocia extremely unreliable.

Once the entire arm and shoulder are exteriorized, it is easy to rotate the baby so as to free up the stuck anterior shoulder. This seminal article was one of the first to evaluate from actual medical records not discharge summaries or birth certificates risk factors for shoulder dystocia.
