Minimally Invasive Surgery for the Treatment of Lumbar Spinal Stenosis: A Comprehensive Review.
Review in Current pain and headache 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
introductionLumbar spinal stenosis (LSS) is a prevalent and debilitating condition characterized by the narrowing of the spinal canal, leading to pain and neurogenic claudication. While open laminectomy is the gold standard for severe cases, it carries significant risks, especially for older patients. The variable success of non-surgical conservative treatments highlights the need for l minimally invasive interventions. This review compares available surgical options for LSS, with a focus on percutaneous image-Guided lumbar decompression (PILD) and minimally invasive spine (MIS) procedures.
methodsA literature review of clinical studies on MIS procedures for lumbar stenosis published between 2000 and 2025 was conducted via PubMed.
resultsThe PILD procedure, which involves the percutaneous removal of hypertrophied ligamentum flavum, has demonstrated statistically significant reductions in pain and improvements in functional mobility in multiple studies, including three Level 1 randomized controlled trials. Pain relief emerges as early as six weeks and is sustained for up to two years, with a low rate of minor complications. Other MIS options include interspinous spacers and endoscopic decompression, which also show positive outcomes in select patient populations.
conclusionThe PILD procedure is a safe and effective MIS treatment for LSS specifically caused by ligamentum flavum hypertrophy in patients who have failed conservative care. While offering reduced morbidity compared to open surgery, its long-term efficacy relative to other MIS and traditional techniques requires further investigation.
