Summary

Intradiscal pressure/volume testing correlates with disk degeneration severity. This simple, risk-free procedure should be a standard preoperative diagnostic step for spinal disc interventions.

Area of Science:

  • Spine surgery
  • Diagnostic imaging
  • Biomechanical testing

Background:

  • Diskograms are commonly used to assess disc degeneration.
  • Assessing intradiscal pressure and volume can provide biomechanical insights.
  • Current diagnostic routines may benefit from enhanced objective measures.

Purpose of the Study:

  • To investigate the correlation between intradiscal pressure/volume recordings and diskographic findings.
  • To evaluate the clinical utility of intradiscal pressure/volume testing in preoperative diagnostics.

Main Methods:

  • Collected 242 sets of intradiscal pressure/volume recordings and corresponding diskograms.
  • Performed statistical analysis to determine the correlation between variables.

Main Results:

  • A significant correlation (p < 0.01) was found between disk compliance and the degree of diskographic degeneration.
  • Intradiscal pressure/volume testing demonstrated high reliability and safety.

Conclusions:

  • Intradiscal pressure/volume testing is a reliable and risk-free method to assess disk degeneration.
  • This testing should be integrated into the preoperative diagnostic routine for patients undergoing spinal disc procedures like chemonucleolysis or percutaneous diskectomy.
