Decompression alone for 62 isolated L1-2 lumbar disc herniation.
Article in Surgical neurology international, 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
Background: Upper lumbar disc herniations (ULDHs) are rare and present significant technical challenges due to the inability to retract the conus medullaris. Here, we reviewed our outcomes treating 62 patients with L1-2-disc herniations with open laminectomy/microdiscectomy (OLM) without fusion. Methods: Between 2005 and 2022, we performed 62 OLM procedures at the L1-2 level without fusion. Our analysis included demographic characteristics and outcomes assessments (Visual Analog Scale leg pain, Modified Japanese Orthopaedic Association score), plus 1-year postoperative dynamic X-rays to confirm stability. Results: L1-2-disc herniations occurred in 0.9% out of a larger series of lumbar discs we reviewed. Patients' presenting symptoms typically included back (95%)/leg pain (82%), cauda equina symptoms/signs (64%), and neurogenic claudication (45%); more than 50% of patients had been symptomatic for over 1 year. Postoperatively, no discs recurred, and patients exhibited neither clinical nor radiological symptoms/signs of instability. Conclusion: The OLM technique for removal of L1-2 lumbar disc herniations resulted in adequate outcomes without evidence of spinal instability.
