Cobb Angle Scoliosis Severity & Progression Calculator Result

Formula

Cobb Angle is measured between intersecting lines drawn perpendicular to the superior endplate of the uppermost vertebra and the inferior endplate of the lowermost vertebra of the spinal curve.

Clinical Pearls

The universally required orthopedic metric directing treatment algorithms between watchful observation, orthotic bracing, and corrective spinal surgery.

Limitations

Inter-observer and intra-observer measurement variability on standard radiographs is typically ± 3° to 5°.
