Clinical outcomes of navigation-assisted versus fluoroscopy-guided UBE-ULBD in single-level lumbar spinal stenosis: a retrospective study.
Article in BMC surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundLumbar spinal stenosis (LSS) is a common degenerative disorder characterized by neural compression, leading to radicular pain, neurogenic claudication, and lower limb dysfunction. Unilateral biportal endoscopic unilateral laminotomy for bilateral decompression (UBE-ULBD) has emerged as an effective minimally invasive surgical technique, but it requires advanced surgical skills and has a steep learning curve. The use of computer-assisted navigation has been increasingly adopted to improve surgical efficiency and safety; however, its clinical effectiveness and safety in UBE-ULBD for single-level LSS remain insufficiently investigated.
methodsA total of 119 patients undergoing UBE-ULBD were included and divided into Group A (navigation-assisted, n = 57) and Group B (fluoroscopy-guided, n = 62), with a minimum follow-up of 12 months. Perioperative outcomes and clinical efficacy were evaluated using operative time, fluoroscopy frequency, estimated blood loss, postoperative hospital stay, complication rates, as well as visual analogue scale (VAS) scores for back and leg pain, Oswestry Disability Index (ODI), and modified MacNab criteria.
resultsNo statistically significant differences were observed in baseline characteristics between the two groups. Group A had a significantly shorter operative time, fewer intraoperative fluoroscopies, and lower estimated blood loss compared with Group B (all P < 0.001), while postoperative hospital stay and overall complication rates did not differ significantly (P > 0.05). No surgical site infections or permanent nerve injuries occurred in either group. Both groups showed significant postoperative improvements in VAS and ODI scores relative to preoperative values; however, no intergroup differences were found at any follow-up point (P > 0.05). At the final follow-up, the excellent/good rate based on the modified MacNab criteria was 93.0% in Group A and 87.1% in Group B, with no significant difference (P > 0.05).
conclusionNavigation-assisted UBE-ULBD can significantly improve surgical efficiency and markedly reduce intraoperative radiation exposure for surgeons, while demonstrating comparable safety and clinical efficacy to conventional fluoroscopy-guided procedures. These advantages highlight its potential clinical value as a safer and more efficient alternative for minimally invasive decompression in lumbar spinal stenosis.
