1 · What the graph read from it

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.

2 · The registry

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

introductionSurgical treatment of the adolescent idiopathic scoliosis consists of a three-dimensional correction, involving correction of the vertebral rotation in axial plane, correction of the coronal and sagittal imbalance. Previously, most studies have considered coronal Cobb angle correction as the main objective. Currently, it is admitted that the restoration of sagittal alignment remains also a primary goal. Bending rods intraoperatively can be complicated, leading to complications such as rod notching or sagittal imbalance. PURPOSE: The aim of this study is to analyze the restoration of sagittal balance postoperatively in AIS using patient-specific rods and compare the sagittal alignment obtained at last follow-up with the preoperative planning.

methodsIn this study, we analyzed the radiological outcomes of 53 AIS patients treated by correction fusion surgery using patient-specific rods between 2019 and 2023. Rods bending was planned by the surgeon, based on spinopelvic parameters from the patient, according to the principles described by Kariman Abelin Genevois (KAG). Demographic data, relevant radiological parameters and classifications were carried out early preoperatively, immediate post-op, 6 weeks post-op, at 6 months, at two years and at last follow up.

resultsMost of the predictions of post-operative changes in sagittal parameters were inaccurate, with only three parameters (thoracic kyphosis (TK), pelvic incidence (PI), and C7 plumb line to S1 (SVA)) showing no significant differences between the predicted values and the early postoperative values. However, thoracic hypokyphosis was corrected in 14 out of 17 (82.3%) patients with preoperative hypokyphosis (< 20°). Out of the 53 patients, only 4 (7.5%) patients had a hypokyphosis postoperatively. Adjusted multivariate logistic regression didn't show any predictive factor for a poor correction of sagittal alignment correction.

conclusionPatient-specific rods are helpful for the surgeon to restore optimal sagittal alignment and the preoperative predictions correspond to the values obtained at last follow-up. LEVEL OF EVIDENCE: Level IV.
