Posterior Epidural Migrated Lumbar Disc Fragment at L2-3 Level Mimicking an Extradural Spinal Tumor: A Case Report.

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: Disc sequestration is well known as a perforation of the fibrous ring and posterior longitudinal ligament, and migration of the fragment to the epidural space. Case Report: A 62-year-old man complained of increased pain and hypoesthesia and muscle weakness of the left lower limb that had started 1 month before. Magnetic resonance imaging revealed a tumor-like mass at the L2-3 level on the posterior side of the dura. The fragment was strongly adhered to the dural sac and was resected piece by piece. Disc herniation recognized at L2-3 compressed the left L3 nerve root and was removed. The histopathological diagnosis was consistent with a degenerated intervertebral disc. All symptoms improved after the surgery. Conclusion: There are few reports about the posterior migrated disc herniation at higher lumbar level. It may be associated with fused segments from L4 to the pelvis due to the previous surgery, which impacted the adjacent segment.
