Scoliosis surgery is typically designed to stabilize the spine by permanently fusing specific segments in their current position. While this can reduce movement and, in some cases, slow further progression, it does not restore normal spinal mechanics or guarantee a straight spine.

In many cases, the spine remains curved after surgery. Because fusion limits motion, surrounding areas of the spine and body often compensate, which may lead to continued imbalance, stiffness, or changes over time — especially as the body adapts or ages.

For this reason, surgery is not always a definitive solution for long-term spinal control, symmetry, or functional movement. Outcomes vary widely based on curve type, age, growth history, and individual biomechanics.

Conservative, non-invasive approaches — such as curve-specific training — are often explored before or alongside surgical consideration, particularly when the goal is to improve control, balance, and long-term function rather than immobilization.
