The Cobb angle is the most widely used measurement for quantifying spine curvature. It is a specific method used primarily in radiology to assess the degree of curvature in conditions like scoliosis.
Understanding the Cobb Angle Measurement
According to the reference [3] and Figure 3.19-Feb-2019, the Cobb angle is defined as:
- The angle formed between the upper border of the upper vertebra and the lower borders of the lowest vertebra of the curved section of the spine.
This measurement identifies the extent of the spinal deformity.
Key Points About the Cobb Angle
- Primary Use: Quantifying the degree of spinal curvature.
- Most Widely Used: It is the standard measurement technique in clinical practice and research for assessing scoliosis and other spinal deformities.
- Method: Based on drawing lines parallel to the endplates of the most tilted vertebrae at the top and bottom of the curve and measuring the angle between these lines (or perpendicular lines).
In essence, the Cobb angle provides a numerical value that represents the severity of the spinal curve observed on an X-ray.
