    This study analyzed the correlation between lumbar core muscle structure and residual chronic low back pain (rCLBP) after Posterior Lumbar Interbody Fusion (PLIF).

  • 2

    Patients were divided into two groups: those with rCLBP and a non-pain control group, with 46 rCLBP patients and 51 NrCLBP patients included in the analysis.

  • 3

    Lower cross-sectional area (CSA) of the psoas major and paraspinal muscles were independently associated with an increased risk of rCLBP after PLIF.

  • 4

    The mean density of the quadratus lumborum was also linked to rCLBP, suggesting muscle density may be a sensitive imaging biomarker.

  • 5

    The study highlights the need for further exploration of muscle morphology's role in rCLBP, as causality cannot be inferred from its retrospective design.
