Questions and Answers

What is scoliosis, and why is it classified as a diagnosis of exclusion?

Scoliosis is a lateral curvature of the spine that is classified as a diagnosis of exclusion because other potential pathologies must be ruled out before establishing it as the primary issue.

What is the main distinction between structural and functional scoliosis?

The main distinction is that structural scoliosis involves a permanent lateral curvature and vertebral rotation, while functional scoliosis develops as a secondary response to other injuries or conditions.

What are some of the developmental associations of structural scoliosis?

Developmental associations include muscular dystrophy, connective tissue disorders, and cerebral palsy.

Study Notes

Scoliosis

  • Scoliosis is a lateral curvature of the spine.
  • It's a diagnosis of exclusion, meaning other pathologies must be ruled out before confirming it as the primary or contributing cause, especially with functional scoliosis.
  • The most crucial factor in addressing scoliosis is identifying its cause, which can be challenging.
  • Many cases are idiopathic (unknown cause) but are often multifactorial.
  • Assessing scoliosis typically involves ongoing evaluation.
  • Two main types:
    • Structural:
      • Exhibits lateral curvature and vertebral rotation to varying degrees.
      • Both rotation and curvature contribute to spinal deformity.
      • Develops due to:
        • Developmental causes (adolescence, but onset can be as early as 3 years old), sometimes associated with conditions like muscular dystrophy, connective tissue disorders, and cerebral palsy.
        • Degenerative causes (older population) – associated with disc herniations, osteoporosis, and vertebral fractures.
      • Differentiating factor from functional scoliosis: fixing structural scoliosis is outside the scope of an athletic therapist, while optimizing function around the condition is within our role.
      • Treatment for adolescents involves bracing and surgery in severe cases, but influence on its development is limited due to the anatomical nature of the issue.
    • Functional:
      • Develops secondary to other injuries, postures, movements (sports/ADL related), muscle imbalances, leg-length discrepancies (which could be anatomical or functional for adaptation reasons), or pelvic/lower extremity malalignments.
      • More relevant to athletic therapists as intervention is possible.
      • Treating scoliosis symptomatically doesn't have a substantial long-term impact.
      • Fixing functional scoliosis takes time as it forms over time.
      • The main goal is to assess the cause and treat it.
      • Hand dominance can significantly impact functional scoliosis, especially in one-arm dominant sports/occupations.
      • A significant portion may be asymptomatic.
  • Scoliotic curves are labeled based on:
    • Region of occurrence (cervical, thoracic, lumbar).
    • Direction of the curve's convexity (right or left).
  • Finding scoliosis can be incidental during the assessment of another issue. Linking the two is possible but not always the case. Addressing one issue may contribute to improvement in the other.

Vertebrobasilar Insufficiency (VBI)

  • VBI involves localized or widespread disruption of blood circulation to the posterior brain and brainstem.

  • The most frequent injury site is C1-C2 due to anatomical features and the significant rotation occurring between these vertebrae which can stretch/compress/kink the vertebral arteries.

  • The most problematic cervical rotation is contralateral (ex., left vertebral artery is most vulnerable with right rotation).

  • Pathologically , VBI is often preceded by transient ischemic attacks and stroke.

  • While a network of redundant vessels exists in the area, unilateral occlusion is rare with a neurological deficit.

  • The most severe form of VBI is arterial dissection, which can have fatal consequences and is frequently associated with traumatic forces (e.g. MVAs, whiplash).

  • Research on cervical spine manipulation faces challenges due to variations in patient health (healthy vs. compromised blood vessels).

  • The vertebrobasilar artery system contains 3 key vessels: left vertebral artery, right vertebral artery, and basilar artery.

  • A pre-manipulation algorithm (Cook, 2007) exists, but the principles should be adapted to mobilization/pre-mobilization techniques.

  • Immediate referral to a physician is required for indiscriminate VBI symptoms with the cervical rotation test.

  • A key symptom is dizziness.

  • A vestibular therapist may be involved in such cases where dizziness is presented.

  • The pre-manipulation position test is crucial before performing spinal manipulation.

  • Cranial nerve testing is crucial for VBI assessment as most are supplied by the VB system, but the olfactory nerve is not affected.

  • Blood pressure monitoring (looking for hypertension) can provide clues, though it's not definitive in identifying VBI.

  • Eye examinations should be conducted as part of the assessment process

  • VBI tests are not definitive, relying on ultrasound to truly clear the vertebral arteries, a significant issue given the lack of imaging.

  • In the absence of clearing the artery, any manipulations/mobilizations/ROM exercises for VBI, should be avoided.

  • There's a strong need for a clinical prediction rule to identify VBI risk as history and screening tests lack strong reliability. It's crucial to avoid false negatives and be cautious due to potential for serious complications. Physician referral remains critical for diagnostic imaging

  • Common differential diagnoses for VBI include: spondylosis, disc pathology, stenosis, upper cervical instability, multiple sclerosis, cerebrovascular accident, tumors, facet dysfunction, concussion, Bell's palsy, CV disease, BPPV, epilepsy, medication side effects.

Thoracic Outlet Syndrome (TOS)

  • TOS involves obstructions of structures emerging from the superior thoracic aperture.

  • Key affected structures include brachial plexus trunks, medial cord of the brachial plexus, subclavian artery and vein, and potentially the axillary artery and vein.

  • Most commonly, TOS is neurogenic (90% of cases).

  • Types of TOS (sorted in order from most to least common and least to most common):

    • Most common: Neurogenic, then Venous, then Non-specific/mixed, then Arterial.

  • Vascular TOS requires physician referral.

  • TOS diagnosis is typically a process of exclusion, with a focus on identifying the underlying cause. A multifactorial and ongoing assessment is crucial.

  • Palpation assessment should include: Upper trapezius, Pectoralis minor, Scalenes, Erb's point, Clavicle, Upper Quadrant Soft Tissues, First rib Joint Play, and Distal pulses.

  • Potential assessment division might include: initial focus on vascular ruling out, followed by treatment, assessment, and finding causes in future appointments.

  • Common Differential diagnoses include: disc pathology, spondylosis, radiculopathy, brachial plexus injury, peripheral nerve entrapment, diabetes, shoulder injury, tumours, multiple sclerosis, Raynaud’s, cardiac events, angina, myofascial pain, and chronic regional pain syndrome.
