Adult Idiopathic Scoliosis

What it is

This is a sideways curve of the spine that began in adolescence (idiopathic, meaning without a single known cause) and has carried into adulthood. As an adult, two things are happening at once: the original curve, and the ordinary wear of aging layered on top of it. That combination is why the concerns in an adult differ from those in a teenager.

What it feels like

In adults the main issues are usually pain, stiffness, and fatigue from the muscles working to hold the spine balanced — and, when the curve narrows the canal, leg symptoms from crowded nerves. Appearance can still matter, but day to day it is comfort and function that most people notice. Many adults live well with a curve that has been stable for decades.

How we follow it

Standing X-rays measure the curve and your overall balance — how your head sits over your pelvis — and comparing them over time shows whether the curve is stable or slowly progressing. An MRI checks the nerves if you have leg symptoms. Balance and progression matter more here than the raw curve number.

How we treat it

Most adults are managed without surgery — physical therapy, core conditioning, activity adjustments, and targeted injections for nerve symptoms. Surgery is reserved for curves that are clearly progressing, throwing off your balance, or causing nerve compression that limits your life. Because adult deformity surgery is a substantial undertaking, I weigh it carefully and aim to do the least that achieves a balanced, stable spine — fusing only what is necessary.

The science — for the curious

The reason balance matters so much in adults is leverage: if the head and trunk drift forward or to the side of the pelvis, the muscles fight gravity all day and pain follows. So the goal of treatment — and of surgery when it is needed — is a spine that is balanced and stable, not a perfectly straight X-ray. And as with any fusion, each level locked in place adds stress to its neighbors, which is why I correct and fuse only as much as the situation truly requires.
