Cobb angle

The Cobb angle is a measurement of bending disorders of the vertebral column such as scoliosis and traumatic deformities.

[2] Unless otherwise specified it is generally presumed to refer to angles in the coronal plane, such as projectional radiography in posteroanterior view.

The Cobb angle is also the preferred method of measuring post-traumatic kyphosis in a recent meta-analysis of traumatic spine fracture classifications.

It was originally used to measure coronal plane deformity on radiographs with antero-posterior projection for the classification of scoliosis.

[9] It has subsequently been adapted to classify sagittal plane deformity, especially in the setting of traumatic thoracolumbar spine fractures.
