Congenital hip dislocation, also known as developmental hip dislocation, is a phenomenon in which the acetabulum becomes shallow or the head of the femur dislocates out of the acetabulum at birth or during development due to certain factors. Although the incidence rate is not high, only 1 per thousand, but once you get and not early diagnosis and treatment, the consequences are delayed the child’s life, and it is important that this is the new mothers carefully can be found so as to cure the disease. Because our country does not have a sound neonatal period of specially trained physicians to carry out a census, so it leads to a lot of children a lifetime of osteoarthritis and varying degrees of disability. Therefore, the current problem is mainly early diagnosis and early treatment. While doctors are required to do their best, new mothers are also required to be attentive so as to achieve early detection and early diagnosis and treatment. Jinan City Hospital of Traditional Chinese Medicine Orthopedics Sun Xiaona the cause of this disease is not yet very clear, some accustomed to carry back baby’s nationalities, such as South Africa, Central Africa, some countries, Hong Kong, and the Korean people, the incidence of its significantly lower; on the contrary, cold, accustomed to the line of the lower limbs tied swaddling babies in the region of the obvious increase, such as Italy, North America, such as the Indians. The incidence of breech delivery is 10 times higher than that of cephalic delivery, and the incidence of cesarean delivery is higher than that of vaginal delivery. It should also be noted that this disease is combined with a high prevalence of other congenital anomalies compared to the general infant population, such as congenital clubfoot, cervical strabismus, and other systemic anomalies; it is rare in some areas of the population and highly prevalent in others. The cause of this phenomenon is unknown and is presumably related to genetic and ethnic factors. New mothers can see that the child’s thighs and calves are asymmetrical to the opposite side, and that the entire lower limb may be thickened, shortened, or thinned, or externally rotated if unilateral, or widened bilaterally at the hip. In terms of skin texture, the skin texture of the buttocks, groin and thigh increases, deepens and moves upward asymmetrically. In terms of limb activity, the affected limb is less active, the pedal force is lower than the other side, and the hip joint can be heard popping sound when changing diapers. Both hips and knees were flexed at 90° each, both legs were together, both heels were aligned, and the knee plane of the affected side was lower than that of the healthy side. Important method of neonatal census: the child is lying down, flexion of the knees, flexion of the hips each 90 °, the mother faces the child’s buttocks, both hands hold both knees at the same time abduction, external rotation, the normal side of the outside of the knee can touch the bed, when a certain degree of limitation of abduction, and the outside of the knee and can not touch the bed, known as the positive test of abduction. When adduction to a certain degree suddenly bounced, then the adduction can reach 90 °, is the most reliable signs of hip dislocation. The treatment of congenital hip dislocation should be based on different ages and adopt different methods. The general principle is early diagnosis and early treatment. Early treatment methods are simple, children have less pain, good results and fewer complications. According to the experience of pediatric orthopedic surgeons in China, children within 3 years of age should be mainly treated with non-surgical treatment, i.e., using external fixation support to stabilize the reset hip joint after closed reset, and children above 3 years of age should be mainly treated with surgical treatment. Diagnosis is more difficult in the neonatal period, but if every newborn can be routinely examined after birth, and the diagnosis is clear within 3-7 days, the treatment will have the best results; if the diagnosis is clear within 1 year of age, it can be successfully treated, and the X-ray examination can be completely normal in the future, which demonstrates the importance of early diagnosis and treatment.
