Discography, a controversial diagnostic tool, offers objective evaluation of spinal discs through volumetric, manometric, and radiographic challenges. When performed with careful patient selection and technique, it proves safe and accurate for pain provocation assessment.

Area of Science:

  • Orthopedics
  • Neurosurgery
  • Diagnostic Imaging

Background:

  • Discography is a long-standing diagnostic procedure for evaluating spinal disc pain.
  • Its interpretation has been historically controversial due to variability in results.
  • Understanding disc anatomy, pathophysiology, intradiscal pressure, and applied loads is crucial for objective interpretation.

Purpose of the Study:

  • To describe the equipment and technique for performing discography using a manometry system.
  • To review the complications and outcomes associated with discography.
  • To highlight discography as a safe, accurate, reproducible, and objective diagnostic tool.

Main Methods:

  • Utilizes a manometry system for volumetric and pressure measurements.
  • Incorporates radiographic imaging (fluoroscopy) to assess disc changes.

Related Experiment Videos

  • Involves pain provocation during the procedure to correlate with patient symptoms.

    • Main Results:

    • Discography provides a physiologic challenge to the disc.
    • When considering intradiscal pressure and applied loads, results become more objective and reproducible.
    • The procedure is safe when indications for patient selection are followed.

    Conclusions:

    • Discography can be a safe, accurate, reproducible, and objective diagnostic tool.
    • Proper technique, patient selection, and interpretation considering anatomy and pathophysiology are key.
    • The combination of volume, pressure, fluoroscopic changes, and pain provocation enhances diagnostic value.
