Myelography

Contributor(s): Frank Andrews, Chris Whitton

Introduction

  • Structures in the vertebral canal can be outlined with contrast medium.

Uses

  • To confirm the nature, extent and site of the cervical vertebral malformation   Spine: cervical vertebral malformation (CVM)    Spine: deformity  (cf normal   Spine: cervical normal flexed - myelogram    Spine: cervical normal neutral - myelogram  ).
  • To confirm a diagnosis of spinal cord compression due to soft tissue changes.
  • To assess spinal cord compression associated with trauma   Spine: fracture  .
  • To differentiate normal cervical static stenosis at C5-6/C6-7 evident radiographically from cases associated with intramedullary lesions.

Advantages

  • Few side-effects.

Disadvantages

  • Requires general anesthesia for complete assessment.

Do not use technique unless the results would alter the management of the case.

  • Standing technique does not permit flexed, extended and ventrodorsal views.
