Discography can cause mechanical changes in the spine. Patient position and injection pressure significantly influence disc bulge and annular strains during this diagnostic test.

Area of Science:

  • Orthopedics
  • Biomechanical Engineering
  • Radiology

Background:

  • Discography is a common diagnostic tool for back pain.
  • Its clinical utility is debated, with limited understanding of associated mechanical changes.
  • Investigating disc deformation during discography is crucial.

Purpose of the Study:

  • To quantify 3D deformations of the posterior annulus during discography.
  • To identify factors influencing these deformations, such as spine position and injection pressure.

Main Methods:

  • Measured displacements of the lumbar posterior annulus during discographic injection.
  • Analyzed data across three different spinal positions.
  • Calculated disc bulge and annular strains from displacement measurements.

Main Results:

  • The combined effects of disc pressurization, spine position, and disc location explained 56% of the variation in bulges and strains (r² = 0.56).
  • Spine position and pressurization alone did not always significantly impact strains.
  • Interactions between spine position, disc location, and pressurization frequently influenced strains and bulges.

Conclusions:

  • Patient positioning during discography significantly affects disc mechanics.
  • Standardizing patient position in clinical discography studies is recommended.
  • Understanding these biomechanical changes can improve diagnostic accuracy.
