Why do children have congenital hip dislocation?

Hip dislocation in infants is often not detected early, because when sick, the child does not feel pain, does not cry. However, if left untreated, congenital hip dislocation can have serious consequences.

When the femoral head of one or both sides of the hip is displaced from the normal position of the hip while the baby is still in the womb, it is called a congenital hip dislocation.
The incidence of this malformation is 1/800 - 1,000 births, occurring more often in females than in males. If detected early, treatment will be much simpler.

There are many causes of congenital hip dislocation in children such as:
Mother's infection or exposure to toxic substances during pregnancy: This is considered the main cause of bone and joint defects in the fetus. including congenital hip dislocation. Besides, the mother's exposure to harmful chemicals during pregnancy such as nicotine, western medicine, dental fillings, chemicals in cosmetics, toxic plastic... also leads to inhibition of bone and joint development. and bone atrophy in the fetus. Inheritance from the mother: Up to 20% of cases of hip dislocation are inherited from parents. Therefore, if a parent has this disease, it is inevitable that the cause of the child will also follow. Chromosomal mutations: The child's body has other abnormalities related to the lower extremities at birth such as loose hip joints in newborns, clubfoot, spade... or stiffness in the joints in the body. is the cause affecting walking easily causes hip dislocation.

There are 8 signs parents need to pay attention to to detect the disease of their baby right after birth:

The foot falls out when the child is lying down with the legs extended. Knee flexion position, the dislocated knee joint is lower. Limit flexion and flexion of the dislocated hip. Leaping gait if bilateral hip dislocation. Barlow's test: This test is applied to children under 6 months of age, when flexing and closing the hip, the femoral head slides out of the joint, creating a "click" sound.
