NGS for Spine Surgery Patients

During revision spinal surgery for aseptic indications, there remains a concern that the failure may have resulted from undetectable subclinical infection. In the common revision indications of hardware loosening and adjacent segment disease it is possible that bacterial colonization and low-grade infection precipitated the failure event. There is also significant controversy on the role infectious processes have in the development of degenerative disc disease (modic changes). In particular, this study will investigate whether discogenic colonization with Propionibacterium acnes (P. acnes) can be associated with modic changes. Whereas, in surgery for known spinal infection, epidural abscess and septic revisions, it is possible that standard culture techniques fail to detect polymicrobial flora or accurate speciation. This may lead to inappropriate antibiotic management that is not addressing the range of pathology present. There remains an incomplete understanding of the role that subclinical infection plays in aseptic spinal revision surgery and degenerative disc disease
