Navigating Post-operative Complications: A Case Report of Cerebrospinal Fluid Leak and Pan-Resistant Enterobacter Infection Following Lumbar Fusion.
Article in Journal of orthopaedic case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Post-operative cerebrospinal fluid leakage and deep surgical site infection are challenging complications after instrumented lumbar fusion, and their coexistence - especially with multidrug-resistant organisms - increases morbidity while jeopardizing neural integrity and implant stability. Case Report: A 65-year-old woman with diabetes mellitus and hypertension developed persistent wound discharge 1 month after L4-L5 decompression and fusion, with cultures revealing pan-resistant Enterobacter infection. Despite serial debridements and empirical antibiotics, she developed a refractory cerebrospinal fluid leak due to occult dural-tear confirmed intraoperatively with fluorescein localization. Management included repeated meticulous debridement, targeted intravenous and intrathecal colistin therapy, and temporary thecoperitoneal shunting for cerebrospinal-fluid diversion, followed by definitive dural repair with shunt removal that achieved complete infection control and leak resolution. At 2-year follow-up, she was asymptomatic with stable fusion and no recurrence. Conclusion: Early recognition of deep infection and prompt multidisciplinary intervention are essential to prevent catastrophic sequelae after instrumented lumbar fusion. Tailored antimicrobial therapy, cerebrospinal fluid diversion, and staged surgical repair can clear infection and achieve durable dural healing while preserving spinal instrumentation.
