Developmental dysplasia of the hip (DDH) is a common disease of the development of hips. Some children with DDH need close reduction followed by immobilization in spica casting, but excessive hip abduction may lead to avascular necrosis of the epiphysis of femoral head. Therefore, this study would like to use IVIM method to help the pediatric orthopaedic doctors to know whether the blood supply of epiphysis of femoral heads is insufficiency or not in patients with DDH after close reduction.
