Scoliosis

In adults, a sideways curve is either an old adolescent curve progressing with age or a new one built by uneven degeneration. Most need monitoring and symptom care — not an operation.

Two kinds of adult scoliosis

Adult scoliosis arrives by two roads. The first is an adolescent idiopathic curve — present since the teenage years, often never treated — that progresses in adulthood as discs degenerate unevenly and gravity compounds the rotation; larger curves, particularly thoracic curves over about fifty degrees, are the most likely to keep progressing. The second is de novo, or degenerative, scoliosis: a new curve built in the fifties and sixties by asymmetric disc collapse and facet arthritis, usually in the lumbar spine. That second kind has its own page — degenerative scoliosis — because its symptoms and decisions differ; this page covers the broader adult picture.

Symptoms

Many adult curves cause no symptoms at all and are found on imaging done for something else. When symptoms come, they usually arise from the degeneration the curve creates rather than from the curve's shape: back pain from arthritic joints and overworked muscles laboring to hold an unbalanced trunk, and leg symptoms — aching, heaviness, numbness with walking — from the narrowing that develops on the concave side of the curve, where the canal and the nerve doorways close down. Loss of height, a visible lean, and clothes that hang unevenly reflect progression. Importantly, curve size and pain correlate loosely: a modest curve with severe narrowing can hurt far more than a large, balanced one.

Diagnosis

Diagnosis starts with standing full-spine X-rays: the curve measured by Cobb angle, and the head's balance over the pelvis assessed from the front and from the side, because sagittal balance — standing upright without effort — predicts disability better than curve size alone. Supine or bending films may be added to judge how flexible the curve remains. MRI is used when leg symptoms or weakness suggest nerve compression, and bone density matters throughout: osteoporosis both accelerates progression and complicates any surgical plan. The working question is never just 'how big is the curve' but 'which structure is generating which symptom.'

What your first visit covers

A first visit measures before it recommends. Expect a review of standing imaging — curve size, balance, and the levels where the canal narrows — a neurological examination directed at the leg symptoms, and a bone health conversation. You will also be asked what the curve is costing you: walking distance, standing tolerance, work, and appearance concerns all count, and they weigh differently for different patients. Most adults with scoliosis leave with a monitoring and symptom-care plan, not an operation date.

Treatment options

Most adult scoliosis is managed without surgery: a conditioning program emphasizing core and trunk extensor strength and posture endurance, activity modification, medication during flares, and treatment of bone density where it is low. Leg symptoms from narrowing within the curve are managed as stenosis — including epidural steroid injections on referral to pain management colleagues when they fit the pattern, since Dr. Choi does not perform injections himself. Bracing in adults is used selectively, mainly for pain relief in specific patterns rather than to straighten anything. Monitoring is active, not passive: periodic standing films to detect progression, and reassessment whenever symptoms change character.

When surgery is considered

When surgery enters the conversation for adult scoliosis, it should enter honestly: these are among the largest operations in spine surgery, often involving long fusions and sometimes osteotomies, with a recovery measured in months and a complication profile that is real even in experienced hands. The indications that justify it are a progressing deformity with loss of balance, disabling leg symptoms from narrowing locked into the deformity, or severe symptoms that have failed genuine conservative care. In carefully selected patients the results can be transformative — and the selection, including medical fitness, bone quality, and realistic goals, is most of the decision. A smaller decompression alone is sometimes the right compromise for leg-dominant symptoms, and that trade-off deserves explicit discussion rather than a default to the largest operation.

When a second opinion can help

Adult deformity is where second opinions change plans most often: the proposed length of a fusion, whether the balance goals genuinely require that much surgery, whether a decompression alone would address the symptoms that actually bother you, and whether bone health should be treated for a period before any operation is scheduled. If you have been quoted a very large operation, an independent read of the standing films is a low-cost, high-value step.

When to seek care promptly

Seek prompt evaluation for progressive leg weakness, new bladder or bowel difficulty, a rapid visible change in posture over weeks rather than years, or new severe pain after a fall. In an osteoporotic spine, that last pattern can mean a fracture rather than the curve itself, and it should not be attributed to the scoliosis without being seen.

Frequently asked questions

What is scoliosis in adults?

Scoliosis is a sideways spinal curve of at least 10 degrees, measured on a standing X-ray, usually with a rotational component. In adults it takes two forms: a curve that began in adolescence and has progressed with age and degeneration, and a de novo (degenerative) curve built in later life by uneven disc and joint wear, usually in the lumbar spine. Adult scoliosis is a different problem from the childhood condition — the questions are progression, balance, and symptoms, not growth.

Does adult scoliosis keep getting worse?

It can, at rates that depend on the curve's type and size. Adolescent-origin curves over roughly fifty degrees, especially thoracic ones, tend to progress slowly through adulthood — on the order of a degree a year in many reported series. Degenerative curves progress as the discs and joints keep collapsing asymmetrically, and they more often announce progression through leg symptoms than through visible change. Monitoring with periodic standing X-rays is how progression is caught rather than guessed at.

Can scoliosis cause back pain?

Yes, but loosely — curve size alone predicts pain poorly. The pain in adult scoliosis usually comes from the degeneration the curve creates: arthritic facet joints, overworked muscles holding an unbalanced trunk, and discs wearing unevenly under asymmetric load. That is why two patients with identical curves can have entirely different symptoms, and why treatment targets the pain generators and the balance rather than the number of degrees. A large, balanced, painless curve may need nothing but monitoring.

Can scoliosis cause spinal stenosis?

Yes — it is one of the main ways adult scoliosis produces leg symptoms. On the concave, or inside, of the curve, the canal and the nerve exit doorways narrow as the vertebrae rotate and the discs collapse, producing stenosis exactly where the nerves need room. The result is the familiar stenosis pattern — leg aching and heaviness with walking, eased by sitting or bending — arising from the deformity's geometry. Treating it means addressing the narrowing and, sometimes, the curve that created it.

When does scoliosis need surgery?

When the curve is progressing with loss of balance, when leg symptoms from narrowing within the deformity are disabling, or when severe symptoms have failed a genuine trial of conservative care — and when bone quality and medical fitness support a large operation. The decision weighs what the curve is costing against what correction demands, and it is individualized. Some patients are best served by a limited decompression for the leg symptoms alone, accepting the curve as it is.

Is scoliosis surgery a big operation?

Honestly, yes. Adult deformity correction is among the largest surgery in the spine field: long fusions, sometimes bone cuts (osteotomies) to realign the spine, several hours of operating, a hospital stay, and a recovery measured in many months, with a complication risk that is real even in experienced hands. In carefully selected patients the payoff — restored balance, relieved leg symptoms, halted progression — can be substantial. The size of the operation is exactly why selection, bone health preparation, and a second opinion matter so much here.
