Feasibility of Minimally Invasive Scoliosis Surgery in Adolescent Idiopathic Scoliosis Exceeding 80° of Curve Magnitude.
Article in Neurospine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo investigate feasibility and effectiveness of minimally invasive scoliosis surgery (MISS) via posterior approach in patients with adolescent idiopathic scoliosis (AIS) presenting with very severe curve exceeding 80°.
methodsA total of 257 flexible AIS patients who underwent deformity correction using posterior MISS were retrospectively categorized into 3 groups based on the curve magnitude: moderate (M group, main Cobb angle <60°, n=142), severe (S group, 60°-80°, n=91), and very severe (VS group, ≥80°, n=24). Radiological parameters, perioperative outcomes, and complication rates were compared among the 3 groups.
resultsThe VS group required significantly longer operative times (p<0.001), more fused segments (p<0.001), and a greater number of rib resections during thoracoplasty (p=0.032) compared to the other groups. Despite these surgical demands, there were no statistical differences in the correction rate (p=0.954) and last follow-up thoracic kyphosis (p=0.830) among the 3 groups. Regarding complications, while the overall complication rate showed no statistical difference, the VS group required significantly more invasive management for pleural effusions (p=0.012).
conclusionPosterior MISS demonstrated acceptable radiological and perioperative outcomes even in flexible AIS with Cobb angles ≥80°. These findings suggest the posterior MISS can be a feasible surgical option for selected very severe AIS patients with sufficient flexibility.
