Title: Differential diagnosis

Differential diagnosis
  1. Neck
  2. Back
  3. Extremities
  4. Floppy infant syndrome

II. Back pain
  • requires careful evaluation if lasts more than 1
    to 2 weeks (in child)
  • usually the result of a serious underlying
    disorder including psychogenic back pain which is
    often difficult to manage

II. Back pain
  • in the past, unlike adults, children were thought
    to uncommonly have back pain related to
    psychogenic causes
  • children with acute or short-lived back pain
    more likely to have muscle and ligamentous strain
    or pain associated with systemic viral infection

II. Back pain
  • History should include
  • location
  • duration
  • radiation
  • character of pain
  • illness or activity preceding its onset
  • Interference with normal daily recreational
    activities should be determined

II. Back pain
  • Examination should seek other signs such as
  • abnormalities in gait
  • configuration of the back (subtle changes in
    contour may offer localizing clues)
  • tenderness on palpation

II. Back pain
  • Skin overlying spine should be carefully
    inspected for
  • dimples
  • tufts of hair
  • hemangiomas
  • other cutaneous changes
  • Any cutaneous changes may denote developmental

II. Back pain
  • Lesions causing back pain may also produce
    neurologic changes in extremities or bladder or
    bowel dysfunction
  • Signs of neuromuscular disease should also be

II. Back pain Most common causes
  • Hyperlordotic mechanical back pain
  • Ligamentous or muscle strain
  • Spondylolisthesis

II. Back pain
  • Lordotic mechanical back pain
  • Reputed to be a common cause in adolescent
  • Pain
  • only in lumbar area
  • variable hyperextension or hyperflexion testing
  • inability to fully flex the spine forward

II. Back pain
  • Lordotic mechanical back pain
  • Kyphosis of thoracic spine present in
    compensation for decreased forward mobility of
    lumbar spine
  • Some have suggested contractures at the facet
    joints as site of pain

II. Back pain
  • Ligamentous or muscle strain
  • History of fall, unusual exercise or other forms
    of trauma should be sought
  • There may be localized tenderness and
    paravertebral muscle spasm
  • Strain probably the most common cause of back
    pain but it should be short-lived

II. Back pain
  • Prolapse of intervertebral disc
  • Uncommon lesion in children

    and bowel control and sensory changes

II. Back pain
  • Brucellosis
  • Small abscesses may develop in vertebrae
  • Generally associated with widespread
  • Acute transverse myelopathy

II. Back pain
Neoplastic disorders Benign tumors

  • Several vertebrae may be wedged anteriorly
  • Pathophysiologic mechanism thought to be prolapse
    of nucleus pulposis into the vertebrae body,
    possibly due to osteoporosis

    be sought such as infection, diskitis or tumor

II. Back pain
Psychogenic pain
  • Back pain may be associated with reaction to
    stressful situations
  • Should always be considered if patients affect
    is inconsistent with symptoms or if findings are

  • Clues to underlying problem should be sought by
    close examination of the skin over spine for
    cutaneous abnormalities

II. Back pain
Miscellaneous causes
