A Radiograph is obtained from a child with skeletal abnormality, What is the name of the angle being measure?

The above shown X-ray image shows cobbs angle. Cobbs angle It is a measure of the curvature of the spine in degrees. The anglebetween intersecting lines drawn perpendicular to the top of the top veebrae and the bottom of the bottom veebrae is theCobbs angle It is measured to quantify the magnitude of spinal deformities, especially in the case of scoliosis , on plain radiographs. Cobb's angle of 10 degree is minimum angulation to define the scoliosis.
