Developmental hip dysplasia refers to abnormal development of the hip joint during infancy, which can limit the range of motion of the hip joint. In severe cases, it may lead to hip dislocation. Early detection and treatment are crucial for preventing complications and improving outcomes. Timely examination and treatment can effectively reduce the risk of hip dislocation and improve the function of the hip joint. For mild cases, treatment may involve the use of bandages or increasing joint range of motion. However, for severe cases, surgical treatment may be necessary.
