Impact of lumbar spinal canal stenosis on paravertebral muscle condition: an observational study in Japan

Key Points

• This research aims to evaluate the relationship between lumbar spinal canal stenosis and the condition of paravertebral muscles.
• Conducted an observational study in Japan
• Analyzed the relationship between stenotic levels and muscle condition
• Assessed muscle atrophy and fat infiltration in patients
• Increased stenotic levels correlated with greater muscle atrophy and fat infiltration
• Anatomical location of stenosis had minimal effect on muscle condition
• Stenosis severity appears to be a major factor in muscle degeneration
