How Common Is Scoliosis? Who Is at Risk?

Scoliosis — an abnormal lateral (sideways) curvature of the spine — affects an estimated 6-9 million Americans, making it one of the most prevalent spinal conditions in the country. Despite its prevalence, scoliosis is frequently misunderstood, underdiagnosed, and undertreated. Many people live with significant spinal curvature for years without realizing it.

At Back 2 Health Chiropractic in Lubbock, TX, we regularly screen for and treat patients with scoliosis. Understanding the prevalence, risk factors, and treatment options can help you and your family get the care you need.

What Is Scoliosis?

A normal spine, viewed from behind, should be straight from top to bottom. Scoliosis is diagnosed when the spine develops a lateral curve of 10 degrees or more (as measured on an X-ray). In more severe cases, the spine may also rotate, causing the ribs on one side to protrude (rib hump) and creating an asymmetrical appearance of the torso.

Scoliosis curves are typically classified by:

• Location — cervical (neck), thoracic (mid-back), lumbar (lower back), or thoracolumbar
• Direction — right-leaning (more common) or left-leaning
• Severity — mild (10-25°), moderate (25-40°), or severe (40°+)
• Type — idiopathic, congenital, neuromuscular, or degenerative

How Common Is Scoliosis?

The numbers may surprise you:

• Approximately 2-3% of the American population has scoliosis, or about 6-9 million people
• Mild scoliosis (10-20 degrees) is significantly more common and often goes undetected
• Adolescent idiopathic scoliosis is the most common form, affecting children between the ages of 10 and 18
• Scoliosis affects males and females roughly equally in mild curves, but females are 8-10 times more likely to progress to curves requiring treatment
• Degenerative scoliosis (also called adult scoliosis or de novo scoliosis) becomes increasingly common after age 60, as age-related spinal degeneration causes asymmetric collapse

Types of Scoliosis

Idiopathic Scoliosis (Most Common)

“Idiopathic” means the cause is unknown. This is the most common type, accounting for approximately 80% of all cases. It is further classified by age of onset:

• Infantile idiopathic scoliosis — develops before age 3; uncommon
• Juvenile idiopathic scoliosis — develops between ages 3-10; uncommon
• Adolescent idiopathic scoliosis (AIS) — develops between ages 10-18; most common form overall

Congenital Scoliosis

Present at birth, congenital scoliosis is caused by malformations of the vertebrae during fetal development (such as hemi-vertebrae or fused ribs). It is less common than idiopathic scoliosis and may require surgical management in severe cases.

Neuromuscular Scoliosis

Associated with neurological or muscular conditions such as cerebral palsy, spinal muscular atrophy, or muscular dystrophy. The spinal curve develops as a result of muscle weakness or imbalance. These curves tend to progress more aggressively than idiopathic scoliosis.

Degenerative (Adult) Scoliosis

This form develops in adulthood as a result of asymmetric disc degeneration, vertebral compression fractures (often from osteoporosis), and facet joint arthritis. It becomes increasingly prevalent with age and is a growing concern in the older population.

Who Is at Risk?

Age

The highest-risk period for the development of idiopathic scoliosis is during the adolescent growth spurt — typically between ages 10-15. The spine is growing rapidly during this period, and curves that are present or developing at the beginning of the growth spurt tend to progress as the spine lengthens. This is why early screening during adolescence is so important.

Female Sex

While scoliosis occurs in both males and females, females with mild scoliosis are significantly more likely to experience curve progression to a degree that requires treatment. The reason is not fully understood, but hormonal factors, body composition differences, and the pattern of the adolescent growth spurt in females are believed to play a role.

Family History

Scoliosis has a clear genetic component. If a parent, sibling, or grandparent has scoliosis, a child’s risk of developing it is significantly elevated. Families with a history of scoliosis should be particularly attentive to regular spinal screening during childhood and adolescence.

Rapid Growth

Any period of rapid growth increases the risk of curve progression in individuals with existing or subclinical scoliosis. This includes the primary adolescent growth spurt as well as secondary growth spurts that can occur in middle-to-late adolescence.

Older Age

After age 60, degenerative processes in the spine — including disc height loss, vertebral end plate changes, and facet arthritis — can create the structural conditions for scoliosis to develop or progress in people who had a straight spine earlier in life.

Signs to Watch For

Scoliosis is often detected through school screening programs or incidentally on imaging taken for other reasons. Signs that may indicate scoliosis include:

• Uneven shoulders — one shoulder sits higher than the other
• Prominent shoulder blade — one shoulder blade protrudes more than the other
• Uneven hips — one hip appears higher or more prominent
• Rib hump — a visible hump on one side of the back when bending forward (Adams forward bend test)
• Visible spinal curve — in severe cases, the curve may be visible through clothing
• Uneven leg lengths — sometimes a functional result of pelvic tilt from scoliosis
• Back pain — particularly in adults with degenerative scoliosis

The Role of Chiropractic Care

Chiropractic care is a valuable component of scoliosis management, particularly for mild to moderate curves. While chiropractic cannot reverse an established structural scoliosis curve, it plays an important role in:

• Reducing pain and improving function — adjustments to the spine and related joints reduce the pain and dysfunction associated with scoliosis
• Slowing progression — through improved joint mobility and muscle balance, chiropractic care may help reduce the rate of curve progression in some patients
• Improving quality of life — many patients with scoliosis report significant improvements in daily comfort, energy, and activity tolerance with regular care
• Postural support — specific chiropractic protocols (such as CLEAR method adjustments) are designed specifically for scoliosis patients

Regular chiropractic monitoring is also valuable for tracking curve stability over time. In Lubbock, TX, our team uses spinal X-rays and careful measurement to establish a baseline and monitor any changes.

For adults with degenerative scoliosis who have associated disc issues, our spinal decompression therapy can help reduce the disc-related component of their pain. You can also learn more about our general chiropractic care approach.

When Is Surgery Necessary?

Surgery (typically spinal fusion) is generally considered for curves above 40-50 degrees in growing children, or for adult curves that are severe, progressive, and causing significant neurological symptoms. The vast majority of scoliosis cases never reach this threshold, making conservative management the appropriate first-line approach.

Get a Spinal Evaluation

If you or your child show any of the signs of scoliosis — or if there is a family history of spinal curvature — a chiropractic evaluation is an excellent first step. We can perform a thorough spinal assessment, order imaging if indicated, and work with your other healthcare providers as needed to ensure you receive appropriate care.
