Treatment of Common Low Back Pain: A New Approach to an Old Problem

Area of Science:

• Neurology
• Anatomy
• Pain Management

Background:

• Low back pain is highly prevalent, yet its underlying pathophysiology remains unclear.
• Existing knowledge of the epidural space and neuroforamen anatomy is reviewed.

Observation:

• Flexible endoscopic observations of the epidural cavity (epiduroscopy) and cadaveric dissections provide new insights.
• A hypothesis is proposed for common low back pain pathophysiology.

Findings:

• Inflammatory material accumulation in a suprapedicular compartment within the neuroforamen is hypothesized to cause pain.
• This inflammation sensitizes the peridural membrane and surrounding periosteum.
• Percutaneous Ablation and Curettage and Inferior Foraminotomy (PACIF) targets the peridural membrane, denervates sensitive structures, and removes inflammatory tissue.

Implications:

• The PACIF procedure demonstrates high effectiveness and safety in initial case reports.
• This novel treatment approach warrants further investigation for managing low back pain.
• Understanding the role of the peridural membrane offers new therapeutic targets.
