Oblique lumbar interbody fusion for the treatment of severe central lumbar spinal stenosis: a retrospective study of 48 patients.
Article in BMC musculoskeletal disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThe use of oblique lumbar interbody fusion (OLIF) to treat severe central lumbar spinal stenosis remains contentious. This study sought to assess the efficacy of OLIF without posterior decompression in the treatment of severe central lumbar spinal stenosis.
methodsBetween October 2018 and October 2022, 48 patients who underwent OLIF were retrospectively analyzed. All patients had a preoperative magnetic resonance imaging diagnostic of severe central lumbar spinal stenosis according to the Schizas classification (grade C or D). All patients complained of low back and leg pain, which presented with intermittent claudication or dynamic radicular pain. The symptoms were mostly relieved in supine position. Clinical and radiological outcomes were evaluated.
resultsSeven patients received stand-alone OLIF. Eight patients were treated with OLIF, and percutaneous transpedicular screw fixation was performed within one week after OLIF. Thirty-three patients underwent a single-stage OLIF with percutaneous pedicle screw fixation. All patients' clinical outcomes improved significantly over time, including ODI (63.1 ± 12.2/17.5 ± 5.8/7.8 ± 4.5/6.9 ± 4.6, p < 0.01), VAS of low back pain (6.1 ± 1.7/2.4 ± 1.0/1.1 ± 0.8/1.0 ± 0.7, p < 0.01), and VAS of leg pain (5.8 ± 1.5/1.9 ± 0.9/0.9 ± 0.8/0.8 ± 0.7, p < 0.05) recorded preoperatively and 1, 3, and 12 months postoperatively. The mean disc height increased from 7.8 ± 2.1 mm preoperatively to 10.4 ± 1.7 mm one week postoperatively (p < 0.01) and dropped to 10.1 ± 1.8 mm 12 months postoperatively (p < 0.01). The segmental lordosis angle increased from 7.7 ± 3.3 preoperatively to 8.9 ± 3.2 at one week postoperatively (p < 0.01) and remained stable at 12 months (8.8 ± 3.3, p = 0.22). The CSA increased considerably over time, from 44.0 ± 18.6 mm2 preoperatively to 65.1 ± 20.8 mm2 (p < 0.01) at one week postoperatively and 124.9 ± 19.2 mm2 at 12 months postoperatively (p < 0.01). Two patients with stand-alone OLIF underwent decompression surgery due to postoperative cage subsidence and recurrence of lower extremity problems. At one year of follow-up, the fusion rate was 97.9%.
conclusionsOLIF combined with pedicle screw fixation is effective in treating severe central lumbar spinal stenosis. It is a good option for patients whose symptoms can be relieved in supine position.
