[Antibiotics should not be used for treating back pain due to Modic changes]

Area of Science:

• Spinal disorders
• Infectious diseases
• Musculoskeletal pain

Background:

• Modic changes are common findings in the spine.
• A proposed link exists between spinal infection and back pain in individuals with Modic changes.
• Previous research has explored the role of bacteria in chronic back pain.

Purpose of the Study:

• To review current Scandinavian research on the association between infection and Modic changes in back pain.
• To evaluate the efficacy of antibiotic treatment for back pain associated with Modic changes.
• To investigate the prevalence and significance of bacterial presence in spinal discs.

Main Methods:

• Review of Scandinavian studies, including a randomized controlled trial (RCT) on antibiotic treatment.
• Analysis of long-term follow-up data comparing patients with and without Modic changes.
• Bacterial analysis of disc samples from patients undergoing surgery for lumbar disc herniation and control groups.

Main Results:

• A Norwegian RCT found no benefit from antibiotic treatment for patients with Modic changes and back pain.
• A Danish long-term study showed similar physical disability but less sick leave in patients with Modic changes compared to those without.
• A Swedish study found comparable bacterial presence in discs of operated and control patients, suggesting surgical contamination rather than infection-related pain.

Conclusions:

• The evidence does not support infection as a primary cause of back pain in individuals with Modic changes.
• Antibiotic treatment appears ineffective for this patient group.
• Bacterial presence in spinal discs is likely due to contamination, not a cause of chronic back pain.
