Management of chronic low back pain

Area of Science:

• Pain Management
• Musculoskeletal Disorders
• Interventional Pain Medicine

Background:

• Chronic low back pain (CLBP) affects millions globally, persisting over 3 months.
• Current treatments include monotherapies, multidisciplinary therapy, and reductionism.
• Many monotherapies demonstrate limited efficacy for CLBP.

Purpose of the Study:

• To review the efficacy of different chronic low back pain treatment categories.
• To highlight the role of targeted interventions based on specific diagnoses.
• To discuss diagnostic tools and emerging treatments for specific CLBP causes.

Main Methods:

• Literature review of CLBP treatment modalities.
• Analysis of diagnostic techniques including joint blocks and discography.
• Evaluation of interventional procedures like radiofrequency neurotomy.

Main Results:

• Monotherapies (e.g., analgesics, NSAIDs, physiotherapy) show limited effectiveness.
• Multidisciplinary therapy offers modest pain relief and improved physical function.
• Diagnostic blocks and discography identify specific pain generators: zygapophysial joints (15-40%), sacroiliac joints (20%), internal disc disruption (>40%).

Conclusions:

• A reductionist approach, pursuing specific diagnoses, is crucial for effective CLBP management.
• Radiofrequency neurotomy effectively treats zygapophysial joint pain.
• Emerging techniques show promise for sacroiliac joint pain and internal disc disruption.
