About Idiopathic Scoliosis

Scoliosis is commonly recognized as a lateral curvature of the spine, although the deformity is three-dimensional and typically involves coronal curvature, vertebral rotation, and changes in sagittal alignment. Curves may occur at any spinal level and vary in magnitude and clinical significance.

Scoliosis may result from identifiable structural, neuromuscular, or syndromic causes, or it may occur without a clearly identifiable underlying mechanism. Idiopathic scoliosis, diagnosed by exclusion, accounts for approximately 80% of cases and most commonly presents during adolescence, particularly during periods of rapid growth.

Clinical impact is variable. Many individuals remain asymptomatic or experience minimal functional limitation, while others may develop pain, cosmetic concerns, respiratory compromise, or progressive functional impairment. Larger curves, particularly those exceeding approximately 30–50 degrees after skeletal maturity, are associated with an increased risk of reduced quality of life and long-term functional limitations.

The natural history and management of idiopathic scoliosis are influenced by age at presentation, growth potential, curve magnitude, and curve pattern. As a result, management strategies differ across the lifespan, and evidence from skeletally immature populations is not always generalizable to adults.

About CCG Care Pathways

Purpose

CCG care pathways provide structured, evidence-based guidance for clinicians delivering conservative, non-operative care for common musculoskeletal conditions. They outline key steps of the clinical encounter, support safe and appropriate decision-making, and assist with referral or co-management when indicated. Pathways are designed as practical, user-friendly tools that complement, not replace, clinical judgment.

Development

Pathways are developed using the best available evidence from high-quality clinical practice guidelines when they exist, and from systematic reviews and expert consensus when guideline evidence is limited or evolving. Content is reviewed periodically to reflect emerging research and current best practices. Input from clinicians, educators, and researchers helps ensure pathways remain relevant, aligned with real-world practice, and responsive to user needs.

Principles of Conservative Care

Musculoskeletal conditions are multifactorial and often influenced by physical, psychological, social, and environmental factors. As such, there is no one-size-fits-all approach to care. Effective management should be ethical, evidence-informed, transparent, flexible, and tailored to individual needs. Shared decision-making ensures care aligns with patient goals and values. Ongoing monitoring and outcome assessment support a person-centred approach and enable timely adjustments to care plans. Care may be delivered in-person, virtually, or through hybrid models, guided by patient preference, access, and clinical judgment.

Disclaimer

CCG care pathways are intended to support, not substitute for, professional clinical decision-making or the advice of a qualified healthcare provider. Recommendations are evidence-informed and presented in simplified, accessible language to support clinical understanding and application. Terms used throughout are not intended as formal diagnostic or billing terminology, nor are pathways prescriptive, authoritative, or regulatory.

Providers are expected to apply their clinical expertise and consult authoritative sources such as regulatory standards and policies, diagnostic classification systems (e.g., ICD-10-CA), scope-of-practice documents, continuing professional education resources, and peer-reviewed literature. Pathways may not apply to every clinical scenario and should always be interpreted in the context of individual patient needs.

Idiopathic Scoliosis Care Pathway

1. Record Keeping

Accurate, timely, and comprehensive documentation is an essential component of high-quality, evidence-based care. Clinical records must clearly reflect patient interactions, clinical reasoning, and progress over time, and should meet all jurisdictional regulatory standards.

Providers are encouraged to use a structured note format, such as the SOAP framework, to support consistency, clarity, and continuity of care.

Subjective: Document the patient’s reported symptoms, concerns, functional changes, contextual factors (e.g., psychosocial or environmental influences), and responses to prior care.

Objective: Record measurable or observable findings, including physical examination results, relevant diagnostic tests, functional assessments, and any clinically significant changes.

Assessment: Provide the clinical interpretation of findings, including diagnostic impressions or updates, identification of key risk factors or modifiers, and evaluation of the patient’s status or progression.

Plan: Outline the management strategy, including treatments delivered, modifications made, patient education and self-management recommendations, referrals, co-management decisions, and planned follow-up.

Documentation should be completed contemporaneously and maintained in accordance with regulatory requirements for privacy, security, and record retention. High-quality records support patient safety, facilitate interprofessional communication, enable shared decision-making, and promote continuity and accountability in care.

2. Informed Consent
  • Definition: A process where the patient voluntarily agrees to proposed healthcare interventions after receiving adequate information on the nature, benefits, risks, and alternatives.
  • Key Aspects:
    • Prior to interaction: Obtain consent before any diagnostic testing or treatment. Ensure the patient understands the planned examinations, treatments, expected outcomes, and is given the opportunity to ask questions.
    • Voluntarily and specific: Consent must be given willingly, without coercion, and pertain to the specific condition and proposed treatment. The patient should also understand that they can withdraw consent at any time. 
    • Transparent process: Consent must be obtained honestly, with a clear explanation of the condition and proposed interventions. Consent is not a one-time event, and involves ongoing discussions with the patient.
    • Patient understanding and agreement:
      • Diagnosis/prognosis: Explain findings clearly, using understandable language and visuals if needed.
      • Treatment plan: Outline recommended treatments and how they align with patient goals. Discuss benefits, risks, and alternatives.
      • Questions: Encourage questions and confirm understanding (e.g., “teach-back”).
    • Documentation: Record the consent process, including information provided, patient questions, and explicit consent given.
3. Health History
  • Apply cultural awareness and trauma-informed care principles.
  • Sociodemographic: Age (noting periods of rapid growth and skeletal maturity), gender, sex (progression more frequent in females), race/ethnicity.
  • Main concern: When and by whom the spinal asymmetry was first noticed; location and perceived rate of change; presence and characteristics of pain (location, intensity, frequency, radiation, aggravating or relieving factors); associated functional or cosmetic concerns.
  • Body systems: Maturation/growth (e.g., menarche in females, voice change in males, recent growth spurt); neurologic; cardiovascular; respiratory; genitourinary; gastrointestinal; muscles and joints; eyes/ears/nose/throat; skin; mental health; reproductive.
  • Health, lifestyle, family, social, and occupational history: Family history of scoliosis or neurologic or musculoskeletal disorders; relevant medical conditions; medications; prior injuries, hospitalizations, or surgeries; physical activity, sleep habits, and general health behaviours; family and caregiver supports; school or work environment.
  • Social determinants of health: Employment, education, childcare responsibilities, housing stability, nutrition, access to care, social supports, discrimination, isolation, and safety concerns including domestic violence or child maltreatment.
  • Previous treatments and responses: Prior screening, imaging, or treatment for scoliosis and response, including any adverse effects.
  • Beliefs and expectations: Understanding of scoliosis, expectations regarding monitoring or treatment, and individual or family goals.
  • Red, yellow, and orange flags: Screen for factors requiring urgent referral or further medical evaluation, as outlined in subsequent sections.

​​Outcomes Assessments:

  • Pain: Pain scales (e.g., NRS), pain diagram.
  • Function and Participation: Impact of scoliosis on daily activities (e.g., PSFS, WHODAS).
  • Quality of Life: Scoliosis-specific and generic measures as appropriate (e.g., SRS-22r, SF-12).
  • Individual Goals: SMART goal setting (Specific, Measurable, Achievable, Relevant, Timely).
  • Patient Feedback: Experience and satisfaction with care.
4. Red Flags : Differential Diagnosis Requiring Medical Referral

ACTION: Refer immediately to emergency care:

  • Suspected spinal infection
    Immunosuppression, recent infection or surgery, history of tuberculosis, unexplained fever or chills, intravenous drug use, or poor living conditions.
  • Acute traumatic spinal injury
    History of significant trauma with concern for spinal fracture or instability.

ACTION: Refer to appropriate medical provider:

  • Non-idiopathic scoliosis
    Features suggestive of congenital scoliosis (e.g., early onset, atypical curve patterns, rigid curves), neuromuscular disorders, or syndromic conditions.
  • Atypical curve patterns
    Left thoracic convexity, which is more commonly associated with underlying pathology (e.g., spinal cord tumors, Chiari malformation, syringomyelia).
  • Significant or atypical pain
    Pain that is severe, progressive, or disproportionate, as idiopathic scoliosis rarely presents with marked pain.
  • Neurological or cutaneous findings
    Neurologic deficits, abnormal reflexes, midline cutaneous lesions (e.g., hairy patches), café-au-lait spots.
  • Suspected malignancy or fracture
    Progressive pain, history of cancer, systemic symptoms (e.g., weight loss, fever), osteoporosis, corticosteroid use, or prior fracture.
5. Orange Flags: Symptoms of Psychiatric Disorders Requiring Referral

Clinicians should promptly address symptoms of potential mental health disorders to prevent harm through appropriate and timely referrals.

ACTION: Refer for immediate care (emergency department, medical/mental health provider):

  • Suicidal ideation: Thoughts, plans, or statements about suicide or feelings of hopelessness.   
  • Severe, acute symptoms: Acute psychological distress, such as psychosis, severe panic.
  • Ideation of harm: Intent or plans to self-harm, commit violence, or harm others.

ACTION: Refer to appropriate medical/mental health provider:

  • Persistent, non-urgent symptoms: Symptoms affecting daily functioning (e.g., low mood, anxiety, sleep disturbances, social withdrawal, substance use).

ACTION: Co-management by non-medical/mental health providers:

  • Triage: Ensure primary management by medical/psychiatric providers.
  • Musculoskeletal (MSK) treatment: Manage MSK conditions related to or comorbid with psychological disorders.
  • Screening tools: Selectively use tools to monitor symptoms and severity, guide care, and support escalation without implying a diagnosis. Tools include:
    • PHQ-9 (depressive symptoms)
    • GAD-7 (anxiety symptoms)
    • FABQ (fear related to physical activity/work) 
    • PCS (catastrophic thoughts) 
    • ORT (opioid risk)
6. Yellow Flags: Psychosocial Factors that May Delay Recovery

Non-health barriers can delay recovery; early identification and intervention can enhance outcomes.

Factors:

  • Individual: Worry, fear of movement, low recovery expectations, limited self-efficacy, reliance on passive treatments, activity avoidance.
  • Social: Lack of family/social support, limited connections.
  • Socioeconomic: Employment status, financial stress, litigation/compensation.
  • Environmental/cultural: Social inequality, unsafe/unsupportive environments.
  • Life events: Major transitions (e.g., divorce, job loss), chronic stressors (e.g., caregiving).
  • Work/school: High stress, poor work-life balance, limited accommodations for injury/illness.

ACTION: Co-management by non-medical/mental health providers: 

  • Education & self-care: Provide resources for (e.g., stress management, coping strategies, graded activity).  
  • Monitor & coordinate: Regularly assess psychosocial challenges; refer to medical/mental health provider if persistent.
  • Screening tools: Selectively use tools to monitor symptoms and severity, guide care, and support escalation (aligned with Orange Flag guidance), without implying a diagnosis. Tools include:
    • PHQ-9 (depressive symptoms)
    • GAD-7 (anxiety symptoms)
    • FABQ (fear related to physical activity/work) 
    • PCS (catastrophic thoughts) 
    • ORT (opioid risk)

7. Physical Examination

General considerations
Conduct the examination with attention to comfort and privacy. Compare findings over time where prior assessments are available.

Observation

  • Posture and alignment in coronal and sagittal planes
  • Shoulder and pelvic height asymmetry, waist creases, trunk shift
  • Adam’s Forward-Bending Test for rib or lumbar prominence
  • Balance, gait, and movement patterns
  • Cutaneous findings (e.g., café-au-lait spots, midline hairy patches, hemangiomas)
  • Overall morphology suggestive of syndromic or connective tissue conditions (e.g., limb length discrepancy, joint contractures, hyperlaxity)

Range of motion

  • Active cervical and thoracolumbar spine range of motion (flexion, extension, lateral flexion, rotation)
  • Note asymmetry, restriction, or symptom reproduction

Hypermobility

  • Assess for regional or generalized joint laxity (e.g., Beighton score) when clinically indicated

Palpation

  • Spinous processes, paraspinal musculature, and rib cage for asymmetry, tenderness, step-offs, muscle tone changes, or soft-tissue abnormalities

Neurological examination

  • Motor strength: Upper and lower extremities as indicated, noting asymmetry or weakness
  • Sensory testing: Dermatomal or regional deficits
  • Reflexes: Symmetry and appropriateness
  • Upper motor neuron signs: Hyperreflexia, clonus, pathological reflexes
  • Lower motor neuron signs: Atrophy, fasciculations, reduced tone

Special tests

  • Scoliometer measurement of angle of trunk rotation during forward bending
  • Clinical surface assessment or 2D photography for aesthetic documentation, where appropriate
  • Additional tests as indicated to evaluate non-idiopathic causes or associated conditions

Imaging considerations

  • Routine radiography is not recommended indiscriminately, particularly in children, due to radiation exposure
  • Imaging may be considered at initial evaluation when trunk rotation is clinically significant (5⁰ or 10⁰) and for monitoring progression when indicated (every 6–12 months)
  • Curve magnitude should be assessed using Cobb angle, recognizing expected inter- and intra-observer variability in interpretation

Assessment frequency and monitoring during growth should align with jurisdictional guidance and individual risk of progression.

8. Clinical Presentations for Idiopathic Scoliosis
  • Pattern: Lateral spinal curvature with three-dimensional deformity (coronal curvature with vertebral rotation), most commonly identified during periods of growth.
  • Onset: Often detected incidentally by the individual, family member, school screening, or healthcare provider.
  • Symptoms: Many individuals are asymptomatic; others may report back pain, fatigue, or cosmetic concerns. Marked or progressive pain is uncommon and suggests an alternative diagnosis.
  • Functional impact: Usually minimal in mild curves; functional limitations may occur with larger or progressive curves.
  • Clinical signs: Asymmetry of shoulders, scapulae, or pelvis; trunk shift; rib or lumbar prominence on Adam’s Forward-Bending Test.
  • Diagnostic considerations: Idiopathic scoliosis is a diagnosis of exclusion after non-idiopathic causes (e.g., congenital, neuromuscular, or syndromic scoliosis) have been ruled out.
  • Imaging: Curves with a Cobb angle <10° are considered normal variants and should not be diagnosed as scoliosis. Radiographic assessment using the Cobb method remains the reference standard for confirming scoliosis and assessing curve magnitude.
9. Conservative Treatment Considerations for Idiopathic Scoliosis

Approach to treatment

The treatments outlined below reflect core domains of conservative care identified across high-quality clinical practice guidelines for idiopathic scoliosis. Management should be individualized based on age, skeletal maturity, curve magnitude and pattern, risk of progression, and individual goals and preferences. Not all domains are required in every case or at every stage. This pathway is not prescriptive and does not include all possible interventions; clinicians should consult relevant guidelines for condition-specific protocols and dosing.

This pathway applies to idiopathic scoliosis. Suspected secondary (non-idiopathic) scoliosis requires referral for further medical evaluation.

(Negrini 2018; Romano 2024)

Patient education

  • Education regarding the nature of idiopathic scoliosis, expected course, and factors influencing progression
  • Reassurance regarding participation in daily activities, sport, and school physical education, unless otherwise contraindicated
  • Discussion of expectations, adherence, and shared decision-making related to monitoring or treatment

Bracing

  • Rigid bracing is a standard component of conservative management for skeletally immature adolescents at risk of curve progression
  • Typically considered for individuals with moderate curves during growth, and may be considered in selected adolescents with curves approximately 45–60 degrees who wish to attempt avoiding surgery
  • Bracing is commonly prescribed for most of the day (often up to ~18 hours/day), depending on brace type, curve characteristics, growth status, and individual tolerance
  • Bracing should be delivered within a structured program with monitoring of fit, adherence, and clinical response

Exercise

  • Exercises are typically emphasized when not wearing the brace
  • Generic therapeutic exercises alone have little to no effect on scoliosis progression or cosmetic outcomes, though they may provide modest quality-of-life benefits. When combined with bracing, therapeutic exercises may be associated with reduced curve progression.
  • Therapeutic exercises focused on posture control, stabilization, and activities of daily living are recommended during periods of growth, particularly in individuals at risk of progression.
  • Physiotherapeutic scoliosis-specific exercises (PSSE) may include scoliosis-specific postural correction, asymmetric strengthening and stretching, breathing techniques, and approaches such as Schroth-based exercises.
  • PSSE should be individualized, progressive, and delivered by clinicians trained in scoliosis management, ideally within an integrated treatment team, with attention to adherence and quality of delivery.

Manual therapy

  • Manual therapy techniques (e.g., gentle mobilization or soft-tissue approaches) may be used only as adjuncts to exercise-based stabilization programs.
  • Manual therapy should not be used as a standalone treatment for scoliosis correction or curve progression.
  • The role of manual therapy is limited to supporting comfort and function within a broader conservative care plan.

Sport and physical activity

  • Participation in general sport and physical activity is encouraged for psychological, neuromotor, and overall health benefits.
  • Sport participation is not a treatment for scoliosis and should not be expected to influence curve progression.
  • Individuals should be supported to remain active according to their interests, abilities, and stage of growth, unless specific medical contraindications are present.
10. Risk and Prognostic Factors for Idiopathic Scoliosis

Risk factors for curve progression

  • Growth potential: Younger age at diagnosis and greater remaining skeletal growth
  • Sex: Higher risk of progression in females
  • Curve characteristics: Thoracic-dominant curves
  • Curve magnitude: Larger initial Cobb angle (e.g., >25° in children; >50° thoracic or >30° lumbar in adults)

Prognosis

  • The clinical course of idiopathic scoliosis is highly variable and influenced primarily by growth status and curve characteristics.
  • Curves identified during periods of rapid growth carry a higher risk of progression, while progression risk is substantially lower after skeletal maturity.
  • Many individuals with mild curves remain stable and asymptomatic, whereas others experience progression requiring intervention.

Negative prognostic indicators

  • Family history of scoliosis
  • Joint or skin laxity
  • Thoracic hypokyphosis
  • Periods of rapid growth
  • Angle of trunk rotation >10°

(Negrini, 2018; Weiss, 2006)

11. Ongoing Follow-up
  • Monitor progress: Reassess symptoms, functional status, and patient-reported outcomes at appropriate intervals. Confirm that care remains aligned with the patient’s goals, values, and expectations.
  • Adjust treatment plan: Continuously realign the management plan based on evolving goals, treatment response, clinical findings, and professional judgment. Modify interventions, dosage, frequency, or focus as needed to support meaningful improvement.
  • Support self-management: Reinforce the patient’s understanding of home strategies, activity recommendations, and behavioural approaches. Encourage adherence and address barriers that may affect progress.
  • Recognize plateaus or change in status: Identify when the patient is improving, stable, or worsening. Reassess for contributing factors such as comorbidities, psychosocial influences, or new functional limitations.
  • Referral and co-management: Consider referral or co-management with an appropriate provider when there is limited or no significant improvement within an expected timeframe (for example 6 to 8 weeks), when new or concerning findings emerge, or when additional expertise is required to support optimal care.
  • Documentation: Record follow-up assessments, changes to the plan, patient feedback, reassessment of goals, and any referral or co-management decisions.
12. Criteria for Discharge
  • Discharge criteria: Establish clear criteria for concluding active care. These may include achieving the patient’s initial goals, demonstrating meaningful improvement in symptoms or function, reaching a plateau in progress, or transitioning to self-management as the primary approach. Consider patient preferences, functional demands, and clinical judgment when determining readiness for discharge.
  • Clinical reassessment: Prior to discharge, complete a focused reassessment to confirm stability of symptoms, functional status, and the patient’s confidence in managing their condition. Address any remaining concerns and ensure no new issues require further evaluation.
  • Post-discharge planning: Discuss ongoing self-management strategies, including activity recommendations, home exercises, behavioural or lifestyle modifications, and symptom monitoring. Provide guidance on when to return for follow-up, when to seek additional care, and what indicators should prompt medical evaluation.
  • Future care needs: Clarify options for episodic care, preventive visits, or re-engagement with the provider if symptoms recur or functional demands change. Encourage ongoing communication if new concerns arise.
  • Documentation: Record the rationale for discharge, the patient’s status at the time of discharge, self-management recommendations provided, and the agreed-upon follow-up plan
