The valve of high-frequency ultrasound in evaluating the growth of hips in patients with suspected developmental dysplasia of hip

Objective To investigate the value of the conventional static ultrasound in the diagnosis of infants who were suspected with developmental dysplasia of hip （DDH）. Methods A total of 1224 hips of 612 infants with clinical suspected DDH were evaluated by sonography and dynamic tracked and observate the development situation of hip to evaluate the hip stability according to the Graf method and Morin method. Results In the 1224 hips ,87.4% were morphologically normal hip （type Ⅰ ）, 9.8% were physiological immature（ type Ⅱ a）, 8.3% were acetabular dysplasia, 4.3% were critical zone hips （type Ⅱ c） , 2.2% were subluxation （ type Ⅲ ）, and 2.9% were dislocation （ type Ⅳ）. The acetabular bone coverage of 1 035 hips were 〉 50% , the acetabular bone coverage of 189 hips were 〈 50%. Conclusion According to the the Graf method and Morirl method, dynamic tracking can decrease the over-treatment and the rate of delay treatment of DDH.
