*3.3.1.1 Oligohydramnios*

The presence of little amniotic fluid has been indicated as a risk factor for DDH [11, 17], but Ömeroğlu et al., in Turkey, in a retrospective study, found no association between oligohydramnios and DDH in children with DDH compared with children with healthy hips [23]. It is assumed that having little amniotic fluid the contraction force of the uterus will be greater and will affect the product; It is also suggested that by decreasing the amniotic fluid, the product will have more space to place their pelvic extremities in extension and adduction, favoring the instability of the hip.
