Association Between Degeneration of the Paraspinal Muscles and Nerve Root Compression in Lumbar Disc Herniation Patients Who Underwent Percutaneous Endoscopic Lumbar Discectomy

Key Points

• The research investigates the relationship between paraspinal muscle degeneration and nerve root compression in lumbar disc herniation patients.
• Evaluated degeneration of multifidus and erector spinae muscles in patients with lumbar disc herniation.
• Measured nerve root compression and assessed improvements post-operatively after a percutaneous endoscopic lumbar discectomy.
• Analyzed the duration of LEP as a factor influencing muscle degeneration and recovery.
• Found significant association between muscle degeneration and nerve root compression.
• Noted improvement in paraspinal muscle condition after surgery, particularly in multifidus and erector spinae.
• Longer preoperative LEP duration was linked to better recovery of muscle function post-surgery.
