Abstract
BACKGROUND
Surgical treatment of vertebral osteomyelitis, discitis, and epidural abscesses is indicated in the setting of failure of antibiotic therapy, neurological deficits, epidural abscess, or spinal instability/deformity. Historically, surgical treatment mandated aggressive debridement and spinal stabilization. However, there is growing evidence that direct debridement may not be necessary and may contribute to morbidity. The purpose of this study was to evaluate the efficacy of posterior instrumentation without debridement in treating spinal infections.
METHODS
A retrospective medical record review was performed to identify patients treated with posterior instrumentation for spontaneous spinal infections. Success of treatment was determined based on postoperative ambulatory status, surgical complications, and need for revision surgery.
RESULTS
Twenty-seven patients treated with posterior-only long-segmented rigid fixation without formal debridement of infected material were included. The most common indications for surgical intervention included spinal instability (67%), neurologic compromise (67%), and failure of prolonged antibiotic treatment (63%). There were no recurrent deep infections in 21 of 22 patients who had long-term follow-up. Four patients required revision surgery, and 3 additional patients requested elective hardware removal. Postoperatively, 70% were ambulatory with no assistive devices postoperatively.
CONCLUSIONS
Vertebral osteomyelitis/discitis are challenging medical problems. Single-stage long-segment fusion without formal debridement combined with antibiotics is effective in the management of spontaneous spinal infections.
CLINICAL RELEVANCE
The present study suggests that acute instrumentation without anterior debridement is associated with a resolution of infection and improvements in neurologic deficits in patient with spontaneous spine infections.
