Does hip dysplasia affect walking? Does congenital dysplasia of the hip affect walking? Developmentaldysplasiaofthehip (DDH), also known as congenital hip dysplasia and developmental hip dislocation, is a collective term for congenital or developmental hip structural abnormalities in infancy and childhood, with approximately 1 in 100 full-term newborns having an unstable hip and 1-2 in 1,000 children having hip dislocation. The incidence of hip dysplasia is about 6 times higher in girls than in boys, about twice as high on the left side as on the right side, and about 35% bilaterally. Hip dysplasia can cause abnormal gait and secondary deformities of the spine in affected children, but it is often painless in infancy and early childhood, so it is easy to be ignored when babies are young, and when they reach adolescence or adulthood, they may develop painful arthritis, as well as lower back pain and degenerative hip disease in adulthood, which in severe cases This can even lead to disability. Many patients are unaware of it when they are young, and only gradually develop it in middle and old age, manifesting as pain in the lower back or thigh root, buttocks, and upper middle thigh, which is alleviated by rest and medication, and as the condition worsens, the pain worsens, making it difficult to wear shoes and socks, stilt legs, squat, and limp, and even cystic degeneration of the femoral head and acetabulum (x-ray performance is similar to necrosis). How to prevent and treat hip dysplasia? Early detection and treatment of hip dysplasia is the key How do you know your baby has hip dysplasia? 1, hip or leg skin pattern asymmetry Observe the height, depth and number of skin patterns on both sides of the baby. If there is hip dysplasia, the skin pattern on the affected leg will be higher and more numerous, but the skin pattern asymmetry may also be a normal phenomenon of momentary skin folds. 2.Changing baby’s diaper is difficult If the hip joint is dysplastic, the hip joint on the affected side cannot be fully abducted, so it cannot be fully opened when changing diapers, and the legs are always closed. 3.The two legs have different pedaling power Feel the pedaling power of the baby’s two calves. If there is hip dysplasia, the pedaling power of one leg may be much less than the other. 4, the length of the two legs are not the same baby supine bending knee (90 degrees), if dysplasia, will be two legs knee joint height is different, the affected side of the leg height is lower. Because when the baby has a backward dislocation of the hip joint, the femoral head moves backward and outward, which will make the legs look shorter. Hip dislocation causes the femur to move upward, making the baby’s affected leg look shorter and accumulate more skin tags. 5, limping If one hip is dysplastic, the pelvis on the healthy side will compensate for the downward tilt when walking. 6, the hip joint popping sound When the legs are opened and closed, you can hear the hip joint “thump” a muffled sound, but the popping sound does not necessarily mean that the hip joint dysplasia, because there are many ligaments in the baby’s hip joint, and some specific posture when moving can also cause popping sound, and we need to further examine to know whether it is. In rare cases, congenital hip dysplasia or dislocation may not be noticed until your baby starts walking, which may be characterized by a slight limp and walking on the affected side of the toes. If you notice any of these problems in your baby, take him to the hospital promptly for an examination. The doctor will not only diagnose hip dysplasia through physical examination, but may also observe the development of the hip joint with the help of ultrasound and X-ray to detect the problem as early as possible.
