Does Rheumatoid Arthritis Affect the Infection and Complications Rates of Spinal Surgery? A Systematic Review and Meta-Analysis

BACKGROUND: Rheumatoid arthritis (RA) is a chronic autoimmune disease that produces synovial membrane inflammation and causes progressive articular damage with function loss. Some controversy exists regarding whether RA is associated with infection and complications after spinal surgery. The present study aimed to determine the effect of RA on spinal surgery infection and complications. METHODS: A systematic literature search was performed in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines. All studies that had compared patients who had undergone spinal surgery with and without RA were included in the analysis. RESULTS: We found significantly greater rates statistically of complications (odds ratio [011], 1.43; 95% confidence interval [Cl], 1.20-1.70; P < 0.05) and infections (OR, 1.69; 95% CI, 1.46-1.95, P < 0.05) in those with RA than in those without RA after spinal surgery. When registry data were excluded, the results suggested that the incidence of complications (OR, 2.24; 95% CI, 0.92-5.44; P = 0.08) and infections (OR, 1.76; 95% CI, 1.50-2.07; P< 0.05) was still greater for the RA group than for the non-RA group. CONCLUSION: When undergoing spinal surgery, patients with RA have a greater risk of operative complications and infection. Surgeons should be aware of these risks and appropriately plan spinal operation for patients with RA to reduce the risk of complications.

Automated summary

This study found that patients with rheumatoid arthritis have significantly higher risks of operative complications and infections after spinal surgery. Even when excluding registry data, the results still show that the incidence of complications and infections is greater for the RA group compared to the non-RA group. Surgeons should be aware of these risks and plan spinal operations accordingly for RA patients to minimize complications.
