The incidence of congenital hip dislocation is generally small, about 1 in 1,000 according to relevant statistics, and is higher in females than in males. It is mainly caused by abnormal development of the femoral head and acetabulum. Congenital hip dislocation is also known as pediatric hip dislocation, developmental hip dislocation, etc. Currently, it is believed that congenital factors are the main cause of its development, the incidence rate of the population is about 1 in 1,000, and the incidence rate of girls is 4 to 5 times that of boys. It is mainly due to the abnormal development of the femoral head and acetabulum of the child, which causes unequal length of both lower limbs, limping, asymmetry of hip and leg lines on both sides, etc. Arthritis, lumbago and degenerative joint lesions can occur in adolescence. The earlier the congenital hip dislocation is detected and treated, the better the prognosis. The main treatments include intervention with hip supports and retractors to maintain the hip flexion and abduction function; reset through plaster fixation and traction, and surgical reset may be required for severe cases. When congenital hip dislocation occurs, it is recommended to go to the regular hospital in time, and choose the appropriate treatment method according to the condition of the child.
