Robotic navigation assistance for spinal fixation in Marfan syndrome: a case report addressing anatomical challenges.
Article in Journal of spine surgery (Hong Kong), 2025. 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
Background: Patients with Marfan syndrome (MFS) can experience spinal deformity characterized by thoracolumbar kyphoscoliosis, severe spondylolisthesis, dural ectasia, vertebral body scalloping, and hypoplastic pedicles. These unique anatomical features complicate conventional spinal instrumentation techniques, rendering robotic navigation assistance (RNA) a viable option in such cases. Case Description: A 41-year-old woman diagnosed with MFS presented with progressive mid-thoracic and low back pain spanning over two decades. Imaging revealed characteristic findings of MFS, including severe leftward thoracolumbar kyphotic scoliosis, dural ectasia, hypoplastic pedicles (1 mm), and vertebral body scalloping. Due to debilitating pain and impaired function, a two-stage thoracolumbar fusion was planned. The 1 Conclusions: At the six-month and three-year follow-ups, the patient reported significant improvements in back pain and functionality, with imaging demonstrating progressive fusion without loosening of the implants. RNA effectively addressed the unique anatomical challenges of hypoplastic pedicles and sacral body scalloping in a patient with MFS-associated spinal deformity. This technology enabled an individualized surgical approach through preoperative planning of instrumentation at each spinal level, allowing for precise placement of juxtapedicular and S2AI screws to achieve stable fixation in anatomically constrained regions.
