Patient's question:
Detailed medical condition and consultation purpose: I noticed that my daughter's right leg seems shorter when she walks, causing her to limp, and she always uses her left leg as the primary support leg when standing. There are no obvious creases in her buttocks, and her right leg is also very flexible.History of previous diagnoses and treatments, as well as their effectiveness: The hospital examination said there was nothing wrong, so we went to another hospital for an X-ray, which also said there was nothing wrong. However, I am still quite concerned and wonder whether the X-ray results can serve as evidence to rule out congenital pediatric hip dislocation?
Doctor's answer:
Hello: Congenital hip dislocation, in the context of China, is more prevalent in the northern regions than in the southern ones. The general incidence rate in the north is around 0.3%, with girls being affected more than boys and the left side being more common than the right. The earlier this condition is treated, the better the outcome. Infants under 2 months old can be treated with simple and effective methods, which can largely restore normal function. Children aged 3 to 12 months can also achieve ideal results through reduction and fixation.Children aged 1 to 3 years, due to prolonged dislocation and varying degrees of soft tissue contracture around the hip joint, require traction before reduction to achieve a more ideal outcome. Children over 3 years old and up to 8 years old have longer dislocation periods, more severe soft tissue contracture, and poorer acetabular development, making manual reduction extremely difficult. Therefore, most require surgery to restore the hip joint. The treatment outcomes for this age group are generally less favorable than those for younger children, but many can still regain normal function.
Children over 8 years old face more challenging treatment and poorer outcomes. Some may be difficult to reduce, potentially leading to lifelong disabilities.
From the above description, we can conclude:
1. The earlier congenital hip dislocation in children is treated, the better the recovery.
2. If congenital hip dislocation is not treated in time, it can lead to disability.
So, how can it be detected early? We recommend performing a simple "frog test" on infants immediately after birth. This involves flexing the child's knees and hips while spreading the hips outward. If the movement is smooth, it is normal; otherwise, further examination is needed. Additionally, observe whether the child's gluteal and femoral creases are symmetrical. If they are asymmetrical, consult an orthopedic doctor for further evaluation.
When changing diapers, pay attention to whether there is any popping or abnormal movement in the child's hip joints. If so, seek medical attention from an orthopedic doctor. Early diagnosis and treatment can prevent lifelong disabilities. We urge you to bring your child to the hospital for standardized treatment as soon as possible.
In Shenzhen, many migrant workers leave their children in their hometowns to work and contribute to the city's development. We hope these parents can pay more attention to their children, identify issues early, and seek timely treatment to ensure their children grow up healthy and happy.
