Bilateral pediatric congenital hip dysplasia can be treated by changing posture, immobilization with support, and surgical treatment respectively, depending on the age group, e.g., within 6 months, from 6 to 18 months, and above 18 months. 1. Within 6 months: children within 6 months can be diagnosed by ultrasound examination, and the femoral head can be naturally reset by changing the posture, such as making the hips abducted in the natural mild hip flexion position, and keeping both lower limbs in the highly abducted frog position. 2.6 to 18 months: 6 to 18 months old children need to take X-ray examination to confirm the diagnosis, and the symptoms can be improved through closed reset, support, plaster immobilization and other methods. 3.18 months and above: children over 18 months old with bilateral pediatric congenital hip dysplasia need to be treated by hip joint capsule cut and reset, pelvic osteotomy and other methods. For bilateral pediatric congenital hip dysplasia, it is recommended to seek timely medical attention for early detection and treatment.
