Navigation-Assisted Endoscopic Excision of Lumbar Vertebral Osteoid Osteoma: A Case Report.
Article in Journal of orthopaedic case reports, 2026. 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: Osteoid osteoma is a benign osteogenic tumor that commonly affects young individuals and may involve the posterior elements of the spine. Surgical intervention is indicated when conservative management fails. We describe a novel technique of navigation-assisted endoscopic excision for the precise and minimally invasive management of lumbar vertebral osteoid osteoma. Case Report: A 21-year-old male presented with nocturnal low back pain for 6 months, partially relieved with non-steroidal anti-inflammatory drugs. Computed tomography revealed a well-defined nidus involving the left lamina of the L2 vertebra in close proximity to neural structures. Navigation-assisted endoscopic excision of the lesion was performed. Intervention and Outcome: Using a 3D C-arm-based navigation system, precise localization and trajectory planning were achieved. Complete en bloc excision of the nidus was performed endoscopically with preservation of surrounding bony and neural structures. The patient experienced immediate post-operative pain relief and was discharged on post-operative day 1. Histopathology confirmed osteoid osteoma, and no recurrence was noted at 15-month follow-up. Conclusion: Navigation-assisted endoscopic excision offers a safe, effective, and minimally invasive alternative for spinal osteoid osteoma, allowing precise localization, reduced morbidity, and histological confirmation.
