Classification of coronal imbalance in adult scoliosis and spine deformity: a treatment-oriented guideline

Coronal malalignment is a frequent condition, usually associated to sagittal malalignment, but it is often misunderstood.

In convex CM, the correction should be obtained at the lumbosacral junction. These slides can be retrieved under Electronic Supplementary Material.
