The Etiology and Treatment of Failed Back Surgery Syndrome in Patients with Primary Lumbar Fixation.
Article in Journal of orthopaedic case 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
Introduction: Low back pain (LBP) ranks among the most common and debilitating musculoskeletal disorders worldwide, affecting about 9.4% of the population and imposing substantial social, economic, and psychological burdens. The aging population has led to a significant rise in chronic LBP and spinal surgical interventions. Nearly 10% of patients continue to experience symptoms beyond 3 months. The biomechanics of the lumbar spine, especially changes in the neutral zone, play a critical role in contributing to instability and pain. Despite advancements in surgical techniques, the success rates of repeat spine surgeries are declining. The objective of the above study was to evaluate the cause and treatment of failed back surgery. Materials and Methods: This prospective observational analysis was conducted at a tertiary care teaching hospital from January 2021 to June 2022. The study included 26 adults with failed back surgery syndrome (FBSS) following lumbar fixation. Results: The straight leg raise test (SLRT) showed significant improvement in most patients over time after revision surgery. At the 3-month and 6-month follow-ups post-revision surgery, SLRT was free in the majority of patients (92.3% and 96.2%, respectively). Visual Analog Scale (VAS) and Oswestry disability index (ODI) scores significantly decreased between pre- and post-operative follow-ups at various intervals (P < 0.001). The percentage improvement in VAS and ODI scores was significant from 1 month to 6 months during follow-up. The VAS score improved by 62.5% at 1 month and 89% at the end of 6 months. The ODI score improved by 77% at 1 month to 97.3% at the end of 6 months. Conclusion: This study demonstrates that revision spinal surgery - specifically utilizing the transforaminal lumbar interbody fusion technique - is a highly effective intervention for the management of FBSS.
