Scoliosis

Scoliosis is a curve of the spine to the side, usually combined with a twist of the bones, that shows on a standing X-ray as an angle of 10 degrees or more. Many people with scoliosis have a mild curve and never need treatment. This page explains the types, tests and treatments, including scoliosis treatment in turkey.

What is scoliosis?

Seen from behind, a healthy spine runs straight down the middle of the back. With scoliosis the spine bends into an S or a C shape. The vertebrae (the stacked bones of the spine) also rotate, so one side of the rib cage or lower back can look more prominent than the other.

This is why scoliosis is called a three-dimensional condition. It is not simply poor posture, and it cannot be corrected by standing up straight. A person with a posture habit can straighten out. A person with true scoliosis cannot.

Who is affected by scoliosis?

Scoliosis can start at any age, but two groups are most common. The first is children and teenagers, where the curve appears around the growth spurt, often between 10 and 15 years of age. Girls are more likely than boys to have curves that progress and need treatment.

The second group is older adults. In people over 50 years, the spine can start to curve as discs and facet joints wear unevenly. This is called degenerative or adult scoliosis. Babies and young children can also be affected, but that is less common and needs a specialist team.

How serious is scoliosis?

Most scoliosis is not dangerous. Curves under 25 degrees rarely cause symptoms or health problems, and many never change. Larger curves matter because they can become visible, stiff and sometimes painful. Very large curves in the chest, usually well above 70 degrees, can reduce lung space and strain the heart. Early review helps decide who simply needs watching and who needs more.

How this page is organised

You will find anatomy, curve types, tests, look-alike conditions, non-surgical care, surgical options, when to consider surgery, and how treatment abroad works. If you are comparing options, the pages on scoliosis surgery and spinal fusion give procedure-level detail. For the wider picture of spine care, see the spine hub.

The spine is a flexible column of 24 movable vertebrae plus the sacrum and tailbone, and in scoliosis that column curves sideways and rotates. Knowing the normal shape makes it easier to understand what the X-ray and the doctor are describing.

What does a normal spine look like?

From the side, a healthy spine has gentle curves: an inward curve in the neck (cervical lordosis), an outward curve in the upper back (thoracic kyphosis) and an inward curve in the lower back (lumbar lordosis). These curves absorb load and keep the head balanced over the pelvis.

From behind, the same spine is straight. The 7 neck vertebrae, 12 chest vertebrae and 5 lower back vertebrae line up, and a plumb line dropped from the base of the skull passes through the crease between the buttocks.

What holds the spine together?

Between each pair of vertebrae sits an intervertebral disc, a tough ring filled with a soft gel that works as a cushion. At the back, paired facet joints guide movement. Strong ligaments run along the column, and muscles on both sides keep it balanced. The 12 thoracic vertebrae also carry the ribs, so a curve in the chest drags the rib cage with it.

What changes in scoliosis?

In scoliosis, one section of the spine bends to one side and the vertebrae rotate toward the outside of the curve. In the chest, this pulls the ribs into a hump on one side (a rib prominence) and flattens the other. Curves are named by where the apex, the most tilted vertebra, sits.

Above and below the main curve, the spine often forms a smaller compensating curve so that the head stays over the pelvis. In growing children the bones on the inside of the curve grow more slowly than on the outside. That uneven growth is why a curve can worsen quickly during a growth spurt.

Why does the curve affect the rest of the body?

A twisted spine changes the shape of the trunk. Shoulders and hips can sit at different heights, a waistline can look uneven, and one shoulder blade may stick out. In larger chest curves, the lungs have less room on the concave side. In the lower back, an asymmetric curve loads discs and facet joints unevenly, which helps explain why adult scoliosis often leads to pain.

Doctors classify scoliosis by age at onset, by cause and by curve size, because each of these changes the treatment plan. The main aim of classification is to predict whether a curve will progress.

What are the main types of scoliosis?

• Infantile and juvenile: onset before 10 years of age. These curves can progress during long growth periods, so early specialist care matters.
• Adolescent idiopathic scoliosis: onset from about 10 years of age until the end of growth. This is the most common type, and it is the one most people mean by idiopathic scoliosis.
• Congenital: present from birth because of a vertebral malformation, often found with scans of the kidneys and heart.
• Neuromuscular: linked to nerve or muscle disease, with a higher risk of progression into adulthood.
• Degenerative (adult scoliosis): develops in mid or later life from wear in discs and joints.
• Adult idiopathic: a curve that started in adolescence and was never treated, which can slowly worsen over decades.

How is curve size graded?

The standard measure is the Cobb angle. On a standing X-ray, lines are drawn along the top of the highest tilted vertebra and the bottom of the lowest tilted vertebra, and the angle between them is the Cobb angle. A different surgeon measuring the same film can differ by about 5 degrees, which is why a change must be larger than that to count as real progression. This approach to scoliosis curve measurement is the basis of nearly every treatment decision.

What other features guide the plan?

Doctors also consider skeletal maturity (how much growth remains), the location of the curve, whether the trunk is balanced, and the flexibility of the curve. A flexible curve that straightens on a bending X-ray is easier to correct than a stiff one. In adults, the shape of the spine from the side, the alignment of the pelvis and the presence of nerve compression are as important as the angle itself.

Scoliosis is diagnosed with a physical exam and a standing X-ray of the whole spine, and the pattern of findings tells the doctor how likely the curve is to progress. Most cases are found at a school check, by a family doctor, or after a person notices an uneven back.

What happens in the clinical exam?

The doctor asks about age, growth, family history, pain, nerve symptoms, breathing and, in girls, the age at which periods began. This last detail helps estimate how much growth is left. The skin is checked for birthmarks or hairy patches over the spine, which can point to an underlying spinal cord problem.

You are then examined standing. The doctor looks at shoulder and hip height, the waist crease, and whether the head is centred. In the forward bend test (Adam's test), you bend forward with arms hanging. A rib or lower-back hump on one side suggests rotation of the vertebrae. A handheld device called a scoliometer can measure the tilt of the trunk.

Which imaging is used?

A full-length standing X-ray, front and side, is the standard test. It shows the curve, the Cobb angle and the balance of the trunk. Extra films taken while bending can show how stiff or flexible the curve is. In growing children the doctor also estimates bone age from the hand or from the pelvis.

MRI is not needed for every patient. It is used when there is unusual pain, nerve signs, a left-sided thoracic curve, very early onset or rapid progression, because those features raise the chance of a spinal cord or brain stem condition. CT scans are sometimes used before surgery to plan screw placement.

What should you send for a remote review?

For a remote opinion, send the original standing X-ray images in digital form (the DICOM files, not photographs of a printed film), the radiology report, and any previous X-rays so that progression can be measured. Add clinic letters, details of any brace, and a brief timeline of symptoms. Photographs of your back from behind, standing and bending forward, are a helpful extra. The medical record review guide explains how the process works.

Most scoliosis is treated without surgery, and the first step for mild curves is simple observation. The plan depends on age, the amount of growth left and the size of the curve, so the right approach for a 12-year-old is very different from that for a 60-year-old.

When is observation enough?

For curves under 25 degrees in a growing child, the usual plan is to check back every 4 to 6 months with an exam and, when needed, a repeat X-ray. Many curves never progress. Observation is not neglect: it allows treatment to start at the right moment. In adults with a small curve that causes no pain, no treatment is usually needed beyond staying active.

How does scoliosis bracing work?

Scoliosis bracing is used for growing children whose curves are between about 20 and 40 degrees and who still have significant growth ahead. A rigid brace holds the spine in a better position while the bones grow. The aim is to stop the curve from getting worse, not to remove it. Braces are often worn for 16 to 23 hours a day, depending on the type, until growth finishes.

Large trials suggest that bracing lowers the proportion of curves that reach the surgical range, and more hours of wear are linked to better results. Night-time braces suit some smaller curves. Adolescents often find the brace hard emotionally, so support from family and a psychologist or physiotherapist can make a real difference.

What about physiotherapy and exercise?

Specific scoliosis exercises, often called physiotherapeutic scoliosis-specific exercises (PSSE), teach the person to correct their posture in three dimensions and strengthen the trunk. Programmes such as Schroth are used in many clinics. Evidence suggests that they may improve curve size and quality of life in mild curves, and they are often combined with a brace. General exercise does not cure a curve but helps back health, fitness and confidence.

Which medicines and injections help?

No medicine changes the shape of a curve. In adults, simple pain relievers, anti-inflammatory drugs (NSAIDs), and short courses of other pain medicines can help flare-ups. Epidural steroid injections or facet joint injections may reduce pain from nerve compression or joint wear for several weeks or months. These treatments relieve symptoms and do not alter the curve itself.

Do chiropractic and other alternative therapies work?

Studies have not shown that spinal manipulation, electrical stimulation, or magnet therapy reduce the size of a curve. A person may still enjoy manual therapy for muscle ache. The key is to avoid delaying a proper specialist review, particularly for a growing child, because the most useful window for bracing can be missed.

Surgery for scoliosis aims to stop a curve getting worse, correct part of the deformity and balance the trunk, and it is usually reserved for large or progressing curves. It is a major operation, so it is chosen only after non-surgical options have been considered.

What is spinal fusion for scoliosis?

The most established operation is spinal fusion. The surgeon fits screws, and in some cases hooks, into the vertebrae and links them with metal rods that are shaped to straighten the spine. Bone graft is placed along the area so that the vertebrae heal into a single solid segment over several months. Once fused, that section no longer moves, but most people keep enough flexibility in the remaining segments for everyday life. The destination-specific page, spinal fusion in turkey, covers local logistics.

What does scoliosis surgery involve in practice?

The wider operation known as scoliosis surgery includes planning with full-length X-rays, sometimes CT scans, nerve monitoring during the operation, and careful anaesthesia. It usually takes 4 to 8 hours for larger curves. Hospital stay is often 4 to 7 days. The details of this work in turkey are described on the page for scoliosis surgery in turkey.

Which approaches exist?

• Posterior fusion: through the back, the standard approach for most adolescent curves.
• Anterior approach: through the side or front for selected lumbar or thoracolumbar curves.
• Growing rods and magnetic rods: for young children with early-onset curves, to allow growth while controlling the curve.
• Vertebral body tethering: a newer growth-modulating technique for selected adolescents, still offered by few centres and with limited long-term data.
• Osteotomy: cutting wedges of bone to restore balance in rigid or severely unbalanced curves, mainly in adults.

What are the trade-offs?

Fusion generally provides a lasting correction and stops progression, but it permanently stiffens part of the spine and carries surgical risks. Adults with degenerative curves may need decompression of narrowed nerves in addition to, or instead of, a long fusion. Shorter operations can relieve leg pain with less risk, but they do not alter the curve. The aim, the number of levels fused and the realistic gain should be discussed openly before you decide.

For help with expected expenses, see the scoliosis surgery cost guide and the spinal fusion cost guide.

Idiopathic scoliosis cannot be prevented, but the harm it does can be reduced by finding curves early and treating those that progress. Healthy habits protect the spine and general health in all age groups.

Can scoliosis be prevented?

There is no known way to stop idiopathic scoliosis from developing, because its cause is not fully understood. Carrying a lighter school bag, better posture or special pillows do not prevent it. Parents sometimes worry that they caused the curve, and it is worth stating clearly that they did not.

How does early detection help?

The most useful step is screening. Children between 10 and 14 years of age benefit from a quick check of the back from a family doctor, school nurse or physiotherapist, particularly if a close relative has had scoliosis. A forward bend test takes about a minute. Referral at 15 to 20 degrees allows time for bracing before the curve becomes large.

If you are an adult with a known curve, an X-ray every few years may be suggested to track change, especially if a curve is over 30 degrees or symptoms change.

What protects the spine as you age?

• Bone health: adequate calcium and vitamin D, weight-bearing exercise and review of osteoporosis risk after the menopause or in later life.
• Muscle strength: regular core and back strengthening to support the spine and limit disc and joint stress.
• Healthy weight: extra weight increases load on discs and facet joints in a curved spine.
• No smoking: smoking is linked with faster disc degeneration and poorer bone healing after fusion.
• Safe lifting: bend at the hips and knees and keep loads close to the body.

What cannot be changed?

You cannot change your genes, your age or the way your spine grew. What you can control is how early a curve is found, how well treatment is followed and how fit your spine is for the future. Understanding related conditions such as lumbar radiculopathy also helps you recognise nerve symptoms promptly.

The outlook for scoliosis is generally good: most people live full, active lives, and those who need treatment usually do well. The path depends on age, curve size and the type of scoliosis.

What happens to curves over time?

In adolescents, curves tend to progress during growth and then slow when growth ends. Curves under 30 degrees at the end of growth usually stay stable. Curves over 50 degrees at that time may continue to worsen slowly. In adults, the risk of progression is higher for larger curves and those with marked rotation or lateral slip.

What is recovery after surgery like?

After spinal fusion for adolescent scoliosis, most patients stand and walk within 1 to 3 days. Many return to school or desk work in 4 to 6 weeks, and gentle activity such as swimming at around 3 months. Contact and high-impact sports are usually delayed for 6 to 12 months, until the surgeon confirms solid fusion on X-ray. Adults often need longer, with full recovery over 6 to 12 months.

Rehabilitation includes walking, posture training and gradual strengthening. The rehabilitation guide describes this process in steps.

How good are the long-term results?

Studies of people treated with fusion in adolescence generally report high satisfaction, good function and the ability to work, study, have children and play sport. Some experience ongoing stiffness or later back pain. Adult scoliosis surgery can reduce pain and improve walking and quality of life, although the complication rate is higher than in teenagers, and the recovery longer.

Can pregnancy and sport continue?

Women with scoliosis can usually have healthy pregnancies, and most women with mild to moderate curves are not at higher risk of complications. Sport is encouraged for fitness and mood. Talk to your specialist about particular activities if you have a brace or an operation planned.

Living well with a curve involves regular check-ups, staying active and seeking help quickly when something changes. If you are weighing treatment options, a free case review can give you a clear starting point.
