Is Oxytocin Induction at Labor a Risk Factor for Developmental Hip Dysplasia?

Developmental hip dysplasia is a common condition with preventable causes, and its etiology is still not fully elucidated. In our study, we aimed to examine the use of synthetic oxytocin during childbirth as a potential risk factor for developmental hip dysplasia. This study involved comprehensive hip examinations on postnatal days 0, 14, 30, and 60, as well as hip ultrasonography results at 6-8 weeks. We specifically focused on healthy girls born with vaginal deliveries, comparing those who were applied with a low-dose oxytocin induction protocol (Group 2) and those who had vaginal deliveries without induction (Group 1). When the examination findings were compared with the hip ultrasonography findings (Type 2a was detected in the left hip of one patient (6.3%) in Group 1 and in the right hip of two patients (11.8%) in Group 2), it was seen that oxytocin induction did not cause a risk for developmental hip dysplasia. The oxytocin induction rate was higher in newborns weighing more than 3400 g ( = 0.04). A low-dose oxytocin protocol applied at birth has not been shown to harm the hip joint in the neonatal period and on ultrasonographic α and β angle measurements applied at 6-8 weeks. However, our study also highlights the need for new studies investigating oxytocin peripheral receptors and their effects, underscoring the importance of our findings in guiding future research in this area.
