Scoliosis in Children: Parent’s Guide for Canada

Scoliosis in children is a condition where the spine develops an abnormal sideways curve, sometimes accompanied by rotation. Instead of growing straight, the spine bends to the left or right, and the curve can range from mild (under 10 degrees) to severe (over 100 degrees in rare cases). This comprehensive parent’s guide covers everything Canadian families need to know — from the earliest warning signs to treatment options available through the healthcare system.

Understanding Scoliosis in Children: Types, Causes, and What Parents Should Know

Most cases of adolescent idiopathic scoliosis are detected during the teenage growth spurt, making early screening especially important. Whether your child has just been diagnosed or you suspect a spinal curve, understanding the condition helps you make informed decisions about monitoring, bracing, physiotherapy, and when surgery may be necessary in Canada.

What Is Scoliosis?

Treatment Options for Scoliosis in Children: Benefits and Considerations

Treatment Option	Best Suited For	Benefits	Considerations
Observation and Monitoring	Curves less than 25°; skeletally immature patients	Non-invasive; involves regular check-ups every 4–6 months with X-rays to track progression	Requires consistent follow-up; no active correction of the curve
Bracing (e.g., Boston or Rigo Chêneau brace)	Curves between 25°–45°; growing children and adolescents	Can halt or slow curve progression in up to 72% of cases when worn as directed	Must be worn 16–23 hours per day; may affect self-esteem and comfort
Physiotherapy (e.g., SEAS or Schroth Method)	All curve severities as a complement to other treatments	Improves posture, core strength, and pain management; widely available across Canadian provinces	Requires ongoing commitment; effectiveness varies by provider training and patient adherence
Spinal Fusion Surgery	Curves greater than 45°–50° or rapidly progressing curves	Permanently stabilizes the spine and significantly reduces curve magnitude	Involves general anesthesia, hospital stay of 3–5 days, and recovery of 6–12 months; wait times vary by province
Vertebral Body Tethering (VBT)	Curves between 35°–60°; skeletally immature patients	Motion-sparing alternative to fusion; allows continued spinal growth and flexibility	Newer procedure with limited long-term data; available at select Canadian pediatric centres

Scoliosis is an abnormal sideways curve of the spine. It happens in a plane that causes the spine to rotate, not just bend. This is different from normal posture issues like slouching.

A mild curve may cause few or no problems. However, a more severe curve can affect a child’s posture, comfort, and quality of life. Most cases are detected during the teenage years, when the body is growing quickly.

Doctors measure spinal curves in degrees. A curve under 10 degrees is considered normal variation. A curve of 10 degrees or more is diagnosed as scoliosis. Curves over 40 to 50 degrees may need surgical treatment.

Types and Causes of Scoliosis in Children

The cause of scoliosis depends on the type. Understanding the type helps doctors plan the best treatment.

Idiopathic Scoliosis

This is the most common type in children and teens. Idiopathic means the cause is unknown. However, it tends to run in families, which suggests a genetic link. If a parent or sibling has scoliosis, your child has a higher chance of developing it too.

Idiopathic scoliosis is further grouped by age. Infantile idiopathic scoliosis appears before age three. Juvenile idiopathic scoliosis develops between ages three and ten. Adolescent idiopathic scoliosis — the most common form — begins during the teenage years.

Congenital Scoliosis

This rare form is present at birth. It happens when the vertebrae (the bones of the spine) do not form properly in the womb. Congenital scoliosis is usually identified shortly after birth or in early childhood.

Neuromuscular Scoliosis

This type is caused by problems with the muscles or nerves that support the spine. Conditions such as cerebral palsy, muscular dystrophy, and spina bifida can lead to this form of scoliosis. It often progresses more quickly and may need earlier treatment.

Signs and Symptoms to Watch For

Scoliosis in children often causes no pain at first. In fact, many cases are found during a routine school screening or a check-up with a family doctor. However, there are physical signs that parents can look for at home.

Common signs of scoliosis include:

• One shoulder sitting higher than the other
• One shoulder blade sticking out more than the other
• An uneven waist or hips
• The body leaning slightly to one side
• One side of the ribcage appearing more prominent when bending forward

As scoliosis progresses, other symptoms may appear. These can include back pain, fatigue after sitting or standing, and in severe cases, a feeling of pressure or numbness in the legs. Tingling or weakness in the arms or legs can also occur if the curved spine puts pressure on nearby nerves.

Furthermore, changes in body shape — such as uneven hips or a visible curve in the back — may become more noticeable over time. For many teens, this can affect self-confidence and emotional well-being.

How Scoliosis Is Diagnosed

If you or your child’s school nurse notices signs of scoliosis, the next step is a visit to your family doctor. Diagnosis involves a combination of physical examination and imaging tests.

Physical Examination

Your doctor will ask about family history, when changes were first noticed, and whether there is any pain. They will then examine your child’s spine, posture, and the range of motion in their back.

One of the most common screening tools is the Adam’s forward bend test. Your child bends forward at the waist with arms hanging down. This position makes it easier for the doctor to see any asymmetry in the ribs or spine. It is simple, painless, and takes only a few seconds.

The doctor will also test reflexes, muscle strength, and sensation. This helps rule out neuromuscular causes and assess nerve involvement.

Imaging Tests

When scoliosis is suspected, the doctor will usually recommend a full-spine X-ray. This allows an accurate measurement of the curve. In some cases, an MRI or CT scan may be needed to look at the spinal cord and surrounding tissues in more detail.

According to Mayo Clinic’s scoliosis diagnosis guidelines, measuring the Cobb angle on an X-ray is the standard method for determining the severity of a spinal curve.

Treatment Options for Scoliosis in Children

The right treatment depends on the size of the curve, the child’s age, and how quickly the spine is changing. Most cases of scoliosis in children do not need surgery. Treatment focuses on managing symptoms and preventing the curve from worsening.

Observation and Regular Monitoring

For mild curves (under 25 degrees), regular check-ups are usually all that is needed. Your child’s doctor will schedule follow-up appointments every four to six months. These visits track whether the curve is staying stable or getting worse.

This approach is common under provincial health plans across Canada. Your family doctor can coordinate referrals to a pediatric orthopaedic specialist as needed.

Bracing

For moderate curves (25 to 40 degrees) in children who are still growing, a back brace is often recommended. The brace does not straighten the spine. However, it helps stop the curve from getting worse during the growth years.

Braces are most effective when worn as directed — often 16 to 23 hours per day. Modern braces are designed to fit under clothing and allow most normal activities. Your child’s orthopaedic specialist will determine the right type of brace based on the location and size of the curve.

Physiotherapy and Exercise

Physiotherapy plays an important role in managing scoliosis. A registered physiotherapist can teach exercises that strengthen the muscles around the spine and improve posture and flexibility. In Canada, physiotherapy services may be partially covered under some provincial health plans or extended health benefits.

Recommended activities often include swimming, daily stretching, and specific posture-improvement exercises. Staying physically active is important for overall spine health. In addition, if your child smokes or is exposed to secondhand smoke, quitting is essential — smoking speeds up spinal degeneration.

Pain Management

Scoliosis itself is often painless in children. However, if discomfort does occur, your doctor may recommend over-the-counter anti-inflammatory medications such as ibuprofen. Heat therapy and gentle massage can also help relieve muscle tension around the spine.

If pain does not improve with physiotherapy and medication, a specialist may consider nerve block injections or epidural treatments. These are forms of targeted local anaesthetic that reduce nerve pain directly at the source.

When Is Surgery Needed?

Surgery is considered a last resort. It is only recommended when other treatments have not worked or when the curve is severe enough to affect health and function.

Scoliosis surgery may be recommended for one or more of these reasons:

• Severe, unmanageable pain that does not respond to other treatments
• Spinal imbalance, where the curve has progressed so far that the head and neck are no longer centred over the pelvis
• Rapidly worsening curves in young patients who are still growing
• Significant impact on quality of life, including breathing difficulties caused by rib cage deformity

The most common surgical procedure is spinal fusion. The surgeon uses bone grafts and metal rods, screws, or hooks to straighten and stabilise the spine. Thanks to advances in modern surgical techniques, many of these procedures are now less invasive, with faster recovery times than in previous decades.

As noted by Health Canada, decisions about surgical treatment should always involve a thorough discussion between the patient, their family, and a qualified medical specialist.

When to See a Doctor

You should book an appointment with your family doctor if you notice any of the physical signs mentioned above in your child. Early detection leads to better outcomes. Do not wait to see if the curve corrects itself — it rarely does without intervention.

If you do not have a family doctor, a walk-in clinic can perform an initial assessment and refer your child to the right specialist. Most provinces also offer pediatric orthopaedic clinics through regional children’s hospitals.

Seek care sooner if your child experiences back pain, changes in bladder or bowel function, or weakness and tingling in the legs. These may indicate that the spine is placing pressure on nerves and needs prompt attention.
