Overview
Scoliosis is a condition where the spine curves sideways in an 'S' or 'C' shape, instead of being straight. This curve can be mild or severe and may happen in children, teenagers, or adults.
Key facts
- Most cases of scoliosis have no known cause (idiopathic).
- Scoliosis is not caused by carrying heavy bags or poor posture.
- Treatment depends on the size of the curve, age, and symptoms – many people with mild scoliosis need no treatment.
Scoliosis is fairly common, affecting about 2–3% of the population. That means out of every 100 people, 2 or 3 have it.
Scoliosis can affect people of any age, but it most often appears in children between the ages of 10 and 15. It is also more common in girls than in boys for curves that need treatment.
Symptoms
- Sudden, severe back pain after an injury or fall
- Loss of control of bladder or bowels
- Sudden numbness or weakness in both legs
- Trouble breathing or chest pain
- ⚠New or worsening back pain that does not improve with rest
- ⚠Curve getting worse quickly over weeks or months
- ⚠Leg numbness, tingling, or weakness that is new
Common symptoms
- One shoulder blade that is higher or more prominent than the other
- One hip that appears higher than the other
- An uneven waistline
- The head not centered over the pelvis
- Back pain (more common in adults with scoliosis)
Symptoms in children
- Clothes hanging unevenly (for example, trouser legs or shirt sleeves)
- One shoulder or hip sticking out more
- Visible curve in the spine when bending forward
- Leaning to one side when standing
Symptoms in older adults
- Back pain that gets worse over time
- Stiffness or reduced flexibility in the spine
- Trouble standing upright or walking
- Numbness or weakness in the legs (if the curve presses on nerves)
Causes
Main causes
- Most scoliosis has no known cause – doctors call this idiopathic scoliosis.
- Some cases are caused by an underlying condition, like cerebral palsy or muscular dystrophy (neuromuscular scoliosis).
- Rarely, scoliosis can be present from birth due to a spine bone abnormality (congenital scoliosis).
Risk factors
- Age: Most common in teenagers during growth spurts.
- Sex: Girls are more likely than boys to have a curve that needs treatment.
- Family history: Scoliosis can run in families, though the exact genetic link is not clear.
When to see a doctor
See a doctor urgently if:
- If you or your child have sudden weakness in the legs, loss of bladder or bowel control, or trouble breathing.
Book a routine appointment if:
- If you notice your child's clothes hanging unevenly or their shoulders look different.
- If you or your child has ongoing back pain that does not go away.
- If you are an adult with a history of scoliosis and your symptoms are changing.
Diagnosis
A doctor will start by asking about your symptoms and checking your or your child's back while standing and bending forward. They look for any signs of a curve or asymmetry.
Tests that may be done
- Physical exam: Checking shoulder height, hip level, and how the spine looks when bending forward (Adam's forward bend test).
- X-ray: This is the main way to measure the curve's angle (called the Cobb angle).
- MRI or CT scan: Sometimes used if the cause is unclear or if there is nerve involvement.
What to expect at your appointment
The doctor will measure the curve on the X-ray. Based on the size of the curve, your age, and how much growth you have left, they will recommend either monitoring, bracing, or other treatments.
Treatment
Treatment for scoliosis depends on the size of the curve, your age, and whether it is causing symptoms. The goal is to stop the curve from getting worse, relieve pain, and improve function.
Self-care at home
- Stay active with low-impact exercises like swimming, walking, or pilates – but check with your doctor first.
- Practice good posture when sitting and standing.
- Use a supportive mattress and chair.
- Apply heat or gentle stretching for back discomfort.
Medical treatments
For curves that are moderate or likely to progress (especially in children), a doctor may recommend a back brace to stop the curve from worsening during growth. In adults, pain relief options like physiotherapy, anti-inflammatory medications (general class, not specific drug names), or injections may help manage symptoms. Only a healthcare provider can advise on the right approach for you.
When is surgery considered?
Surgery is usually only considered for severe curves (typically over 50 degrees) that continue to worsen despite other treatment, or if the curve causes pain, breathing problems, or nerve issues. The most common surgery is spinal fusion, where the curved bones are straightened and held together with metal rods and screws.
Living with this condition
Most people with scoliosis lead normal, active lives. You may need regular check-ups to monitor the curve, especially during growth or if symptoms change.
Lifestyle tips
- Keep up with general exercise to strengthen back and core muscles.
- Listen to your body – avoid heavy lifting if it causes pain.
- If you wear a brace, follow your doctor's instructions on how many hours to wear it each day.
Diet and exercise
A balanced diet rich in calcium and vitamin D helps keep bones strong. Exercise like swimming, yoga, or walking can improve flexibility and reduce discomfort. Always talk to your doctor before starting a new activity.
Mental health and emotional wellbeing
Having scoliosis, especially in teenage years, can affect self-esteem because of changes in appearance or wearing a brace. It is important to talk about your feelings with someone you trust. If you feel anxious or depressed, reach out to a healthcare professional or a mental health support line.
Prevention
Most scoliosis cannot be prevented because the cause is often unknown. However, early detection can help manage the curve and prevent it from becoming severe. Regular check-ups are important for children during growth spurts.
Screening programmes
Some countries, including the UK, do not have routine school screening programs, but doctors can check for scoliosis during regular health visits. If you are concerned, ask your doctor to do a quick back exam.
Complications
If left untreated
- Curve may worsen over time, especially during growth.
- Severe curves can cause chronic back pain or changes in posture.
- Very large curves (over 80–90 degrees) can reduce lung capacity and make breathing harder.
- Nerve compression leading to numbness or weakness in legs.
Long-term outlook
Most people with scoliosis live full, active lives without major problems. With proper monitoring and treatment when needed, the outlook is excellent. Even for those who need surgery, most recover well and have significant improvement in symptoms.
