How do you detect a congenital hip without missing a beat? When a baby is born, what happens to her or him that causes congenital hip dislocation? How to strictly control newborns in order to detect congenital hip dislocation without fail: 1. Universal screening: All newborns must be screened within 3 months of birth. 2. Focused screening: The focus of screening is on newborns with high-risk factors, such as breech position, female infants, first-born babies, family history of “prevertebral hip”, unequal lower limbs, Down’s syndrome, wobbly walking, hip pain after activity, oblique neck, inversion of foot and metatarsal bones, etc. 3. Focus on avoiding: focus on avoiding delayed subluxation caused by certain diseases, such as cerebral palsy, pediatric palsy, hip contracture, spinal cord disorders, Down’s syndrome, Marfan syndrome and multiple epiphyseal dysplasia. First of all, it is important to emphasize that not all hip asymmetries (e.g., different depths, lengths, and numbers of skin tags) are “hip first”, but if there are hip asymmetries, it indicates a high risk of “hip first”. However, if there is an asymmetry of the hip pattern, it indicates a high risk of hip prematurity. 1.The child is suffering from left hip dislocation, we can see that the left hip stripe is deeper and longer, and one side is high and the other side is low. If the child has a left hip dislocation, we can see that the hip lines on both sides are not only different in height but also unequal in number. 3, The child’s left hip is dislocated, and the left knee is lower than the right knee. This test is called the “Allis test”, which requires us to bend the hip and knee of the child and bring the heels together. If the knees on both sides are not the same height, then we should highly suspect whether there is hip dislocation. 4, the child’s left hip dislocation. This test is called the “frog test”, which requires bending the hip and knee joints on both sides and abducting the hip joints at the same time, like a small frog. Then we should consider the possibility of hip dislocation. Tips: If you find suspected hip dislocation, you should go to a professional medical institution such as pediatric orthopedics for diagnosis and treatment. Early diagnosis within 3 months of birth, after regular and continuous conservative treatment, most children can achieve good treatment results.
