Coronal imbalance is defined as lateral deviation of the T1 plumbline with substantial displacement from the midline of the pelvis for more than 20 mm. Coronal imbalance is often associated with sagittal plane deformities. Classifications related to coronal alignment have been defined by Obeid and Bernajo. It is about the type of curvature in classifications, segmental pathologies, degenerative status of the disc and fusion levels, and offers helpful techniques in achieving coronal balance.
