Description
Cobb angle is a measurement used for the evaluation of curves in scoliosis on an AP radiographic projection of the spine.
Single Cobb Angle measures the angle between the vertebrae of the curve deformity (scoliosis) that have the end plates with the maximum slope. The image of the spine must be in the AP view.
Scoliosis is defined as a lateral spinal curvature with a Cobb angle of 10° or more.
Measurements
The measurement made by the procedure is displayed in the image:
- Single Cobb Angle (SCA): angle between the Superior line and the Inferior line.
Auxiliary references

- Superior Line: a line passing through the upper and lower edge of the superior vertebrae that has the end plate with the maximum slope;
- Inferior Line: a line passing through the upper and lower edge of the inferior vertebrae that has the end plate with the maximum slope.
