WebMar 16, 2015 · An Austrian orthopedist, Reinhard Graf, first introduced US examination of the hip in 1980. His technique included the calculation of numerous angles, a complicated classification system of hip subtypes, and the orientation of the B-mode images, so that all hips were displayed on right coronal projections.

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 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 ... WebThe Graf method subscribes to a table of α and β angles to provide a quantitative classification system, 2 while the dynamic (Harcke) technique for position and stability has qualitative definitions. 14 New … dads recovery
