Step one? Determine the terminal vertebra of scoliosis. The upper and lower vertebral bodies are the most inclined vertebral bodies pointing to the convex and concave side of the spine. The convex vertebral space of scoliosis is wider, but the first vertebral body that begins to widen on the concave side is not considered as a part of curvature, so the adjacent vertebral bodies are considered as the final vertebral body of curvature.

Step two? Draw a horizontal line on the upper edge of the vertebral body of the upper vertebra and a horizontal line on the lower edge of the vertebral body of the lower vertebra. Draw a vertical line for each of two horizontal lines.

Third step

What is the intersection angle of two vertical lines? Cobb. Horn. Note: For a large lateral bend, the orthogonal angle of the above two horizontal lines is also equivalent to? Cobb. Horn. Thereby measuring the angle of lateral bending.

If the included angle is less than 20, it is usually mild scoliosis, and no special treatment is needed, only muscle exercise is needed. If the included angle is 20-40, it belongs to moderate scoliosis and needs to be treated with corrective braces. If the included angle exceeds 40, it indicates that scoliosis is serious and generally requires surgery and brace fixation. Therefore, the measurement of scoliosis angle is very important for scoliosis patients, which is not only beneficial to diagnosis, but also beneficial to treatment.

Explanation of the term Cobb angle: the intersection angle between the vertical line at the upper edge of the cephalic vertebra and the vertical line at the lower edge of the caudal vertebra is Cobb angle. If the upper and lower edges of the head vertebra are unclear, we can take the connecting line between the upper and lower edges of the pedicle, and then the intersection angle of the vertical line is Cobb angle.
