II. Epidemiology

  1. Most common Partial Cord Syndrome

III. Pathophysiology

  1. Hyperextension of the Cervical Spine (e.g. fall onto face)
  2. Edema and Hemorrhage into the central cord (gray matter and lateral Corticospinal tracts)
  3. Images
    1. CordSyndrome.jpg

IV. Precautions

  1. Have a high index of suspicion in Trauma
  2. Findings may initially be subtle and mistakenly attributed to peripheral injury

V. Causes

  1. Older patients (most common)
    1. Cervical Spondylosis
    2. Cervical SpineOsteoarthritis
  2. Athletes
    1. Hyperextension with ligamentum flavum buckling
  3. Other mechanisms
    1. Unrestrained in Motor Vehicle Accident

VI. Signs

  1. Bilateral motor weakness
    1. Upper extremities affected more than the lower extremities
    2. Distal extremities affected more than proximal extremities
  2. Sensory deficiency
    1. Variable
    2. Hyperesthesia may be present

VII. Imaging

  1. MRI Spine without contrast (preferred)
  2. CT Spine
    1. Typically performed as initial study in Trauma
    2. May demonstrate Fracture or spinal subluxation
    3. However, CT is unlikely to identify cord compression

VIII. Management

  1. Consult Neurosurgery
  2. Decompression Surgery
    1. In acute Trauma-related cases, may result in better neurologic outcomes

IX. Prognosis

  1. Better than with other Partial Cord Syndromes
