Infection with bacteroides thetaiotaomicron during posterior decompression and dynamic stabilization of the lumbar spine: a case report and review of the literature.

Patient and surgical risk factors have often been implicated for postoperative posterior spinal wound infection. A 56-year-old male with widely disseminated multiple myeloma presented with severe back pain and lower extremity weakness as a result of fracture and collapse of the L4 vertebral body. Posterior decompression involving bilateral pedicle resection and partial L4 corpectomy was performed. Stabilization was performed by Dynesys instrumentation of L3-5, screw supplementation with polymethylmethacrylate, and posterolateral fusion was performed. Postoperatively, the patient suffered from multiple infections, including Bacteroides thetaiotaomicron, which were eventually resolved with antibiotic as well as incision and debridement treatment regimens. In cases with numerous perioperative risk factors for infections, the best therapeutic approach may be a preventative one. An understanding of the relevant risk factors may enable the physician to facilitate a perioperative condition best suited for optimal treatment. A case report of infection with Bacteroides thetaiotaomicron during lumbar decompression and dynamic stabilization as well as a review of the literature regarding infection risk factors are presented.
