“…Around half of all cases with shoulder dystocia occur with infants who weigh less than 4000 g (Berle et al: 44 % [3]; Stein et al: 40.5 % [4]). Numerous risk factors for shoulder dystocia have been reported in the literature [1,[3][4][5][6]. They include maternal risk factors such as obesity (BMI > 30), maternal weight gain of more than 15 kg during pregnancy, diabetes mellitus, multiparity, late-term birth (more than 7 days late), induction of labour, shoulder dystocia at anamnesis, and pelvic anomalies.…”
