Template:Backpain1 the differential diagnosis of acute onset lower back pain, with bowel and bladder dysfunction, sensory and motor deficits,

Classification of pain in the back based on etiology Diease Clinical Manifestation Diagnosis Comments
Symptoms Signs Lab findings Imaging
Onset Duration Quality of pain Radiation Stiffness Fever Rigors and chills Headache Nausea and vomiting Syncopy Weight loss Motor weakness Sensory deficit Pulse Deficit Heart Murmur Bowel or bladder dysfunction Horner's syndrome
Neurological Arachnoiditis[1] Acute Hours Dull aching pain Head, neck and back +/- + +/- +/- +/- +/- +/- +/- +/- - - +/- +/- CSF
  • Elevated protein with normal or low glucose

Culture and sensitivity

  • May be due to TB or Meningitis

Nucleic acid tests

  • Helpful in tuberculous meningitis
Radiography
  • Thickened nerve roots

CT

  • Narrowing of subarachnoid space
  • Irregular collections of contrast material
  • Thickened nerve roots

MRI

  • Study of choice shows indistinct cord outline
  • Usually caused by meningitis or TB
Cauda equina syndrome[2][3] Acute Hours Severe, sharp local pain Rarely to sacroiliac joint - - - - - - - + +/- - - +/- - CBC
  • To rule out anemia

Electrolytes, blood urea nitrogen, and creatinine

  • To rule out renal failure and retroperitoneal hematoma

Erythrocyte sedimentation rate

  • To rule out inflammatory origin

Syphilis serology

  • To rule out meningovascular syphilis
Radiography
  • May show vertebral erosions

MRI

  • Of choice and may show nerve root abnormalities

Duplex

  • For vascular abnormalities

Lumbar puncture

  • For inflammation
Electrical studies:

EMG

  • Done to rule out acute denervation

SSEPs

  • Done to rule out multiple sclerosis
Epidural abscess[4][5] Acute Variable Dull, throbbing pain Locally - +/- +/- +/- +/- +/- +/- +/- +/- - - +/- +/- CBC
  • May show leukocytosis, left shift, thrombocytopenia, and anemia

ESR

  • Elevated

Culture and sensitivity

  • To identify causative organism

Immunohistochemical staining

  • Includes gram stain, special stains for fungi and mycobacteria, also consider brucella
MRI
  • Of choice and demonstrates fluid collection

CT

  • Demonstrates fluid collection

Radiography

  • Demonstrates osteomyelitis or vertebral collapse
  • LP carries risk of spread of infection
Radiculopathy[6][7] Acute Variable Severe, shooting pain Anterior thigh and knee +/- - - - - - - +/- +/- - - +/- -
  • Typically no specific lab findings

Radiography

  • To rule out serious underlying etiology

CT

  • Demonstrates disc herniation

MRI

  • Demonstrates disc herniation and nerve root impingement

Myelography

  • Used preoperatively to visualize spinal anatomy accurately

Discography

  • To localize a symptomatic disc
  • Disc herniation is the most common cause of nerve impingement
Sciatica[8][9][9] Acute Minutes to hours Severe, shooting pain Posterior thigh, buttocks and knee +/- - - - - - - +/- +/- - - +/- - To exclude other pathologies
  • CBC with differential
  • ESR
  • Alkaline and acid phosphatase level
  • Serum calcium level
  • Serum protein electrophoresis

Radiography

  • With technetium-99m labeled phosphorus to indicate bone mineralization status

CT

  • Demonstrates disc herniation

MRI

  • Demonstrates disc herniation and nerve root impingement

Myelography

  • Used preoperatively to visualize spinal anatomy accurately

Discography

  • To localize a symptomatic disc
  • May have a psychological component
Spinal cord compression[2][3]

- Thoracic spine

- Lumbar spine

Acute Minutes to hours Severe and localized Locally, may radiate below lesion - - - - - - - +/- +/- - -

+/-

- Neoplasm must be suspected and is ruled out by
    • CBC - May demonstrate a pancytopenia
    • Prothrombin time and activated partial thromboplastin time - May be prolonged
    • Metabolic profile, including calcium level and liver function - May indicate metastasis
MRI
  • May demonstrate tumors and collapse of intervertebral spaces
  • May distinguish between bone lesions and malignancy

Radiography

  • May demonstrates bony destruction or calcification

Nuclear imaging

  • To identify neoplasms
  • Aggressive radiotherapy is often needed
