Scoliosis & Spinal Deformity

What Is Scoliosis?

Scoliosis is a sideways curvature of the spine — more than 10 degrees — that can develop in children, adolescents, or adults. On an X-ray, it can look like a single C-shaped curve or a double S-shaped curve, and may develop in the neck, chest, or lower back.

Most people picture scoliosis as a childhood condition, but spinal deformity affects adults too — either as a continuation of a curve from childhood, or as a new "degenerative" curve that develops later in life from age-related wear and tear of the spine.

Types of Spinal Deformity

Adolescent Idiopathic Scoliosis (AIS)

The most common type, appearing during the adolescent growth spurt, with no single identifiable cause.

Neuromuscular Scoliosis

Curves associated with conditions like cerebral palsy or spinal muscular atrophy.

Scoliosis Associated with Neurofibromatosis

A genetic condition that can cause more aggressive curve patterns.

Degenerative (Adult) Scoliosis

Curves that develop later in life due to disc and joint wear and tear, often alongside spinal stenosis.

Kyphosis

An exaggerated forward rounding of the back.

Signs to Look For

• One shoulder higher than the other
• One shoulder blade more prominent than the other
• Uneven waist or hip height
• Trunk shifted to one side
• Clothes hanging unevenly

These signs can be subtle. Many curves are first noticed by a parent, a teacher, or even incidentally on an X-ray taken for an unrelated reason — not because of pain. Scoliosis is rarely painful in its early stages, though adult degenerative scoliosis can present with back and leg pain similar to spinal stenosis.

What Causes It?

Idiopathic (Unknown Cause)

The majority of adolescent scoliosis cases have no single identifiable cause, though there is likely a genetic component.

Neuromuscular Conditions

Conditions affecting muscle control, such as cerebral palsy, can lead to progressive curves.

Congenital Causes

Some children are born with vertebrae that didn't form normally, causing a curve from a young age.

Degenerative Changes

In adults, age-related disc and joint wear can gradually cause the spine to curve, especially when combined with osteoporosis.

How Is It Diagnosed?

A clinical examination, including the forward-bend test, is usually the first step. A standing, full-length X-ray of the spine confirms the diagnosis and allows the curve to be measured precisely in degrees — the Cobb angle. MRI is reserved for atypical curve patterns, before surgical planning, or when there's a concern about nerve involvement.

Can Scoliosis Be Treated Without Surgery?

Yes, for most patients. Treatment depends heavily on the curve's size, location, and how much growth remains (in children) or how much the curve is progressing and causing symptoms (in adults).

Non-Surgical Treatment Options

Observation

Most small curves simply need periodic monitoring — an exam and X-ray every 4–12 months — particularly during the adolescent growth spurt, when curves are most likely to progress.

Bracing

For moderate, growing curves in children, a brace can help control progression until growth is complete.

Physiotherapy and Pain Management

For adults with degenerative scoliosis, core strengthening, physiotherapy, and pain management are often the first line of treatment.

When Is Surgery Recommended?

Surgery is considered when:

• A curve is large and likely to keep progressing (typically above 45-50 degrees in growing children)
• An adult curve is causing significant pain, imbalance, or nerve compression
• Bracing has failed to control a progressing curve
• The deformity is affecting lung function or daily activities

Surgical Options

Posterior Spinal Fusion with Instrumentation

The standard approach for correcting and stabilizing a curve using screws and rods.

Vertebral Column Resection and Pedicle Subtraction Osteotomy

Used for severe, rigid deformities that need more extensive correction.

Minimally Invasive Approaches

Used where appropriate, particularly for some adult degenerative cases.

Dr. Kshitij Chaudhary trained in complex spinal deformity surgery at Harvard Medical School (Beth Israel Deaconess) and the Twin Cities Spine Center, Minneapolis — among the leading centers for deformity correction worldwide.

What Is the Recovery Like?

Recovery from scoliosis surgery typically involves a hospital stay of several days, with most patients walking within a day or two of surgery. Return to school or light activities usually takes several weeks, with full recovery and return to sports over several months. Your surgeon will give you a specific timeline based on the extent of your surgery.

Frequently Asked Questions

Does a heavy school bag cause scoliosis?

No — this is a common myth. Scoliosis is not caused by backpacks, poor posture, or sitting habits.

Will my child's curve definitely get worse?

Not necessarily. Curve behavior depends on size, location, and how much growth remains. Many small curves never progress to need treatment.

Is scoliosis surgery very risky?

Like any major surgery, it carries risks, but with modern techniques and experienced teams, scoliosis correction has a strong safety record and can be transformative for the right patient.

Can adults develop scoliosis even if they didn't have it as a child?

Yes — degenerative scoliosis develops in adulthood due to wear and tear of the discs and joints, independent of any childhood curve.

Will scoliosis affect my child's ability to be active or have children later?

In the large majority of cases, no. Most people with scoliosis, treated or untreated, lead fully active lives, including sports and pregnancy.

When Should You Seek Medical Attention?

See a spine specialist if you notice a visible curve or asymmetry, or if back pain in an adult with known scoliosis is new, worsening, or accompanied by leg pain, numbness, or weakness.
