TL;DR
Although shoulder dystocia was observed more frequently with increasing birth weight, current limitations in estimating birth weight antenatally with accuracy preclude its practical use as a reliable predictor.
Abstract
Historic obstetric risk factors for shoulder dystocia are not useful predictors for the event. Furthermore, although shoulder dystocia was observed more frequently with increasing birth weight, current limitations in estimating birth weight antenatally with accuracy preclude its practical use as a reliable predictor.

JAMAThe Effectiveness and Costs of Elective Cesarean Delivery for Fetal Macrosomia Diagnosed by Ultrasound
491 Citations1996Dwight J. Rouse
For the 97% of pregnant women who are not diabetic, a policy of elective cesarean delivery for ultrasonographically diagnosed fetal macrosomia is medically and economically unsound, although in pregnancies complicated by diabetes, such a policy appears to be more tenable, although the merits of such an approach are debatable.

C Cesarean section is recommended as the delivery method for diabetic gravidas whose estimated fetal weight is 4000+ g and if others confirm the risk, the authors advise serious consideration of cesareansection for gravidas who are carrying fetuses estimated to be 4500- g and who experience an abnormal labor.

Most of the traditional risk factors for shoulder dystocia have no predictive value, shoulder dyStocia itself is an unpredictable event, and infants at risk for permanent injury are virtually impossible to predict.

Shoulder dystocia is not a reliably predictable event in labor and the majority of cases occur without these risk factors, while strong downward traction on the head is associated with the greatest degree of neonatal trauma, whereas McRoberts maneuver has the least.

Direct fetal manipulation techniques used to alleviate shoulder dystocia are not associated with an increased rate of bone fracture or brachial plexus injury.

To evaluate the role of prolonged second stage of labor (PSS) as a warning sign for shoulder dystocia, 9864 deliveries at LAC-USC Women's Hospital were retrospectively reviewed and infants weighing in excess of 4 kg were at increased risk of shoulder dyStocia compared with infants weighing less than 4 kg.

It is concluded that in the group of pregnancies delivering neonates greater than or equal to 4000 gm, the occurrence of shoulder dystocia cannot be predicted from clinical characteristics or labor abnormalities, and that the occurrence is not evidence of medical malpractice.

Cases of neonates with documented permanent Erb palsy that occurred either in the absence of shoulder dystocia or in the neonate's posterior arm in the presence of anterior shoulder dyStocia are reviewed to support the notion that the etiology of permanent brachial plexus palsy associated with birth may not be related to traction.
