No. After an individual assessment, appropriate care may include observation, scoliosis-specific rehabilitation, or a brace during growth. Surgery is considered for selected larger or progressive curves, or when scoliosis causes important health or functional limitations.
What determines the treatment approach?
Clinical decisions consider the Cobb angle, curve pattern, age, remaining skeletal growth, evidence of progression, symptoms, balance and day-to-day function.
Two people with the same curve measurement may need different approaches, especially if one is still growing and the other is skeletally mature.
Observation, a brace and physiotherapy
Some mild or stable curves are monitored. For selected patients who are still growing, a brace may be recommended to reduce the risk of progression, with attention to fit and adherence.
Physiotherapeutic scoliosis-specific exercises (PSSE) can support individualized correction, postural control and daily activities. They may complement bracing, but are not an automatic substitute for a brace or surgery when either is clinically indicated.
When might surgery be considered?
In adolescents, a spinal surgeon may discuss surgery when curves approach or exceed approximately 45–50° or are at substantial risk of further progression. This is a common decision threshold, not an automatic rule.
Examples of health or functional problems that may prompt a surgical assessment include:
- A severe, progressive curve with marked spinal imbalance affecting standing or mobility.
- For very severe curves, possible effects on respiratory function or breathing; this is not typical of mild scoliosis.
- In some adults, persistent disabling back or leg pain, nerve compression symptoms or impaired walking and everyday activities despite appropriate non-operative care.
Neither pain nor an X-ray measurement alone determines the final decision. Imaging, examination, anticipated benefits, risks and alternatives all matter.
Who makes the surgery decision?
A qualified spine surgeon assesses whether an operation is appropriate and discusses its goals, risks and alternatives. Decisions should be shared with the patient and, where relevant, their family. Rehabilitation and follow-up may still play a role along the care pathway.
Important: New or progressive neurological weakness, a significant change in walking or notable breathing difficulty requires timely medical assessment rather than simply waiting for rehabilitation sessions.
Key takeaway
Most importantly, scoliosis care should match the curve, its progression risk and the individual. Observation, bracing, rehabilitation and surgical assessment each have a place when clinically appropriate.
