Spinal energy balance can predict post-operative spine alignment in Lenke 1 Adolescent Idiopathic Scoliosis.

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
purposeThe preoperative planning of adolescent idiopathic scoliosis (AIS) remains largely debated. We hypothesized that adopting a biomechanical energetic framework could provide valuable insights for exploring the impact of spinal arthrodesis. Using this approach, we conducted a comparative analysis to quantify discrepancies between in silico simulations derived from preoperative radiographs and the actual three-dimensional spinal alignment obtained from post-operative imaging.
methodsFifty-two consecutive patients with Lenke Type 1 AIS (mean age: 16 years; mean thoracic Cobb angle: 52°) who underwent posterior spinal fusion were included in the analysis. All patients had complete biplanar radiographs at three time points: preoperatively, post-operatively and at two-year follow-up. Discrepancies between in silico simulated surgery, calculated using preoperative radiographs and a biomechanical model, and actual clinical outcomes were quantified using two metrics: maximum coronal/sagittal deviations (MaxC/MaxS) from T1 to L5, and a comprehensive predictability factor (
resultsMean MaxC was 4.7 mm (SD=4.9) and MaxS was 5.7 mm (SD=3.8). Mean values of
conclusionThe distribution of biomechanical energy obtained from preoperative radiographs is reliable to simulate spine alignment after arthrodesis in a Lenke 1 AIS cohort.
