Ultrasonic Measurement Of Hip Joint And Early Diagnosis Of Developmental Dysplasia Of Hip In Infant

Background:Developmental dysplasia of hip(DDH) is a frequent disease of skeletal muscular system in infant.There is about 1% to 10% infants to be prone to developmental dysplasia,dislocation,and semiluxation of hip in the borning.The safety and confidence of medical examination and X-ray examination are disputing, but high-resolution ultrasonic wave can transmit articulatio coxae which is not ossification.DDH can be observed dynamicly with ultrasonography and ultrasonography can provide credible basis for earlier diagnosis of DDH . Developed countries advocate all new born infant should be checked up by ultrasound. So DDH is detected and treated early. The screening is not carryed out in our country especially in the western part.Objective:The objective of this study is to investigte the ultrasonic appearance and measurements of infant normal hip and ultrsonic diagnostic standard DDH and to establish the foundation for screening of...
