Final answer:
The most common risk factors for DDH of the hip include gender, family history, breech presentation, and oligohydramnios.
Step-by-step explanation:
The most common risk factors for Developmental Dysplasia of the Hip (DDH) include:
- Gender: DDH is more common in girls than boys.
- Family history: Having a close relative with DDH increases the risk.
- Breech presentation: Babies who are born breech (buttocks or feet first) have a higher risk of DDH.
- Oligohydramnios: Low levels of amniotic fluid during pregnancy can increase the risk of DDH.
While these are some of the most common risk factors, it is important to note that DDH can also occur in the absence of these factors.
