Adult Scoliosis & Deformity Surgery

Realigning and stabilizing the spine when curvature or imbalance limits daily life.

Written and medically reviewed by Jonathan Acosta, MD · Fellowship-trained orthopaedic spine surgeon · Last reviewed October 2026

What it is

A larger, more complex operation (or staged operations) to correct an abnormal curvature or alignment of the adult spine. It combines decompression of compressed nerves with realignment and fusion — often over multiple levels — using a combination of the interbody and posterior techniques described above1.

Why it's done

Adult scoliosis surgery aims to relieve pain and nerve compression and to restore a balanced, upright posture when the curve or imbalance is causing significant symptoms that haven't responded to nonsurgical care. Because these are among the most individualized operations in spine surgery, the plan is built specifically around your curve, your symptoms, your bone quality, and your overall health, and I combine whichever approaches best achieve a balanced correction. Lateral approaches like XLIF are often part of the strategy because they can correct deformity through smaller incisions1.
