Improper formation and function of the hip socket. The ball and socket joint in the child’s hip joint will slip out of the socket with movement. The cause is unknown, but there are factors that contribute with such as:
• Genetic factors & birth order
• Physiologic factors: maternal hormone
• Mechanical factors: intrauterine position (breech presentation)
CDH is more common in girls than in boys, but any infant can have the condition.
This is why your child’s doctor will routinely check the newborn for signs of hip dislocation.
The term congenital dislocation of the hip dates to the time of Hippocrates. It has been diagnosed and treated for several hundred years. Ortolani, an Italian pediatrician in the early 1900s, evaluated, diagnosed, and treated hip dislocation. Galeazzi later reviewed more than 12000 cases with CDH.
What are the symptoms of CDH?
There may be no symptoms, or the baby has symptoms such as:
• Limited range of motion
• Delayed gross motor development
• Legs differ in length
To diagnose this condition there are many screening tests done by your doctor before the child is 3 months. Imaging tests like ultrasounds for babies younger than 6 months old, and X-ray to examine older babies and children.
If the baby is younger than 6 months of age, it is likely to be fitted for a Pavlik harness which presses hip joints into the socket. The baby may wear it for6-12 weeks depending on age and severity.
If the child is 18 months and older, they may need surgery.
