The earlier hip dysplasia is detected, the higher the cure rate is, and the vast majority of young children can be cured, but if you wait until adulthood, the probability of cure will be reduced and may leave sequelae. 1. Hip dysplasia is a congenital disease, which refers to the structural abnormality of the hip joint in infancy and childhood, resulting in dislocation of the hip joint, unequal length of the lower limbs and other gait abnormalities such as limping. 2. Hip dysplasia is generally a congenital disease, and the earlier the disease is detected and the younger the patient is, the better the cure will be. If the disease is detected in time and the patient is a newborn baby, for example, a toddler under 7 months old, the probability of success of cure can reach more than 95% through conservative treatment. Repositioning is usually done under anesthesia and immobilized in a cast. After immobilization, orthopedic braces are worn for correction. 3. However, with the progress of the disease and the development of the child, the cure rate will gradually decrease as the age increases. Even in the later stage, surgical treatment should be taken. Surgical treatment is to improve the pathological state of hip dislocation and subluxation and to improve the symptoms, but it surely can’t reach the effect of 100% cure without sequelae. The cure rate of surgery is about 90%. The earlier hip dysplasia is treated, the higher the cure rate. If the disease is not treated until adulthood, it is usually treated through surgery, and the probability of cure is small and may leave sequelae. It is recommended that children with hip dysplasia be treated as early as possible.
