WebJan 25, 2024 · The Graf classification system is commonly used to evaluate hip dysplasia, but it has limitations. Patients are classified into groups based on acetabular angle appearance on ultrasound images. This angle is derived from the depth and shape of the socket of the hip bone where the head of the femur fits. WebThe hip of a normal infant has a Graf alpha angle of ____________ degrees. A. Less than 43 B. More than 60 C. Between 43 and 60 D. Less than 77 B. More than 60 The … WebThe Graf technique uses a coronal section through the mid acetabulum and assesses hip morphology without assessing stability, which by definition needs a dynamic assessment as an attempt is made to sublux and reduce the hip. The key measurement is the alpha angle, which is a measurement of acetabular depth, by effectively assessing the osseus ... church candle holder stands
