A predictable cascade of junctional failure following progressive long-segment fusion: an 11-year case analysis.
Article in Journal of surgical 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
Instrumented spinal fusion is a common treatment for degenerative spinal disease but may lead to progressive mechanical and biological complications, especially in long multilevel constructs. We report the case of a 62-year-old woman who developed serial adjacent segment degeneration, pseudarthrosis, implant failure, vertebral fractures, and progressive deformity over 11 years following posterior lumbar fusion. Multiple revision surgeries with stepwise cranial extension to the upper thoracic spine were required. Despite advanced fixation techniques-including multi-rod constructs, iliac fixation, and CT-navigated instrumentation-recurrent mechanical failure occurred. The final presentation involved an unstable thoracic fracture with impending spinal cord injury, necessitating urgent revision with vertebral body replacement and cranial extension into the cervical region. This case highlights the cumulative biomechanical and biological burden of long-segment fusion and underscores the importance of careful patient selection, bone health optimization, and long-term follow-up.
