Scoliosis & Kyphosis: Differential Diagnosis
(In a Page: Signs and Symptoms)

Scoliosis

  • Idiopathic (75–80% of cases) scoliosis usually occurs in otherwise healthy patients; pain and neurologic deficits are rare; right thoracic curve is most common, then double curve (right thoracic and left lumbar); named by convex side
    –Infantile (birth to 3 years): Rare in the U.S.
    –Juvenile (4–10 years): Uncommon
    –Adolescent (11 years to skeletal maturity): Occurs mostly in females
  • Neuromuscular scoliosis
    –Common with paralytic disorders
    –More severe, almost always progressive
    • Congenital scoliosis
      –Failure of formation or segmentation

    Kyphosis
  • Postural roundback
    • Scheuermann's disease
      –Second most common pediatric spinal deformity
      –Cannot voluntarily correct
      –Angulation in mid- to low-thoracic spine
    • Congenital kyphosis
      Less common etiologies (“zebras”)
    • Post-thoracotomy
    • Marfan's syndrome
    • Neurofibromatosis
    • Achondroplasia
    • Diastrophic dwarfism
    • Specific neuromuscular disorders (e.g., cerebral palsy, syringomyelia, polio, muscular dystrophy, cord tumor/trauma)

Scoliosis: Differential Diagnosis
(In A Page: Pediatric Signs and Symptoms)

    • Idiopathic scoliosis
      –Lateral deviation or curvature of either the thoracic or lumbar spine greater than 10°
      –Right thoracic curves are most common
      –Usually presents in early adolescence
      –Girls > boys
  • Risk factors for progression
    –Curve >20°
    –Age less than 12
    –Skeletal maturity, Risser stage 0–1
    • Infantile idiopathic scoliosis
      –Presents at 0–3 years old
      –Left thoracic curve more common
      –Boys > girls
      –85% spontaneously resolve
      –Must rule out spinal cord disease or congenital cause of scoliosis
  • Juvenile idiopathic scoliosis presents at 3–10 years old and is similar to adolescent (idiopathic) scoliosis
  • Neuromuscular scoliosis
    –Related to cerebral palsy, muscular dystrophy, myotonic myopathy, and spinal muscular atrophy
    –Tends to progress more rapidly and even continues after maturity, as compared to idiopathic scoliosis
    –Pulmonary complications seen with severe curves >90°
    • Congenital scoliosis
      –Failure of formation or segmentation of spinal vertebra
      –Rapid progression and worse prognosis is associated with unilateral unsegmented bar with contralateral hemivertebra
  • Other causes
    –Tumor, infection, neurofibromatosis, metabolic bone disorders, and Marfan syndrome

Scoliosis: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

Scoliosis may be functional, structural, or idiopathic. Functional (postural) scoliosis usually results from a discrepancy in leg lengths rather than from a fixed deformity of the spinal column; it corrects when the patient bends toward the convex side. Structural scoliosis results from a deformity of the vertebral bodies, and it doesn’t correct when the patient bends to the side. Structural scoliosis may be:

❑ congenital: usually related to a congenital defect, such as wedge vertebrae, fused ribs or vertebrae, or hemivertebrae; may result from trauma to zygote or embryo

❑ paralytic or musculoskeletal: develops several months after asymmetrical paralysis of the trunk muscles due to polio, cerebral palsy, or muscular dystrophy

❑ idiopathic (the most common form): may be transmitted as an autosomal dominant or multifactorial trait. This form appears in a previously straight spine during the growing years. Brain stem dysfunction, possibly due to a lesion of the posterior columns or the inner ear, may be the cause.

Idiopathic scoliosis can be classified as infantile, which affects mostly male infants between birth and age 3 and causes left thoracic and right lumbar curves; juvenile, which affects both sexes between ages 4 and 10 and causes varying types of curvature; or adolescent, which generally affects girls between age 10 and achievement of skeletal maturity and causes varying types of curvature.

Scoliosis: Causes
(Handbook of Diseases)

Scoliosis may be functional or structural. Functional (postural) scoliosis usually results from poor posture or a discrepancy in leg lengths, not fixed deformity of the spinal column. In structural scoliosis, curvature results from a deformity of the vertebral bodies.

Structural scoliosis may be one of three types:

❑ Congenital scoliosis is usually related to a congenital defect, such as wedge vertebrae, fused ribs or vertebrae, or hemivertebrae.

❑ Paralytic or musculoskeletal scoliosis develops several months after asymmetrical paralysis of the trunk muscles from polio, cerebral palsy, or muscular dystrophy.

❑ Idiopathic scoliosis (the most common form) may be transmitted as an autosomal dominant or multifactoral trait. This form appears in a previously straight spine during the growing years.

Idiopathic scoliosis can be classified as infantile, which affects mostly male infants between birth and age 3 and causes left thoracic and right lumbar curves; juvenile, which affects both sexes between ages 4 and 10 and causes varying types of curvature; or adolescent, which generally affects girls between age 10 and achievement of skeletal maturity and causes varying types of curvature.
