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

backgroundAlthough instrumented fusion is the most widely accepted surgical treatment for adolescent idiopathic scoliosis, it leads to permanent spinal motion loss and an increased risk of adjacent segment degeneration. Consequently, there is great interest in finding nonfusion methods to correct scoliosis in patients with adolescent idiopathic scoliosis. The aim of this manuscript is to report a case of adolescent idiopathic scoliosis (Lenke 5C) treated by dynamic stabilization without fusion using the Dynesys system. CASE PRESENTATION: The patient was a 17-year-old East Asian female. Before the operation, the major lumbar curve was 32.2° and the lumbosacral curve was 18.5°, with the Risser sign at grade 4. The procedure was performed using the Wiltse approach. The extent of fixation was from the cephalic horizontal vertebra to sacrum. The scoliosis was corrected by the unequal length of the spacers on the concave/convex side. We obtained a good correction of scoliosis, which was maintained during the 5-year follow-up. We also observed less intraoperative blood loss, faster postoperative recovery, and more motion preservation.

conclusionIn this case, dynamic stabilization was demonstrated to be technically feasible for the treatment of thoracolumbar/lumbar moderate scoliosis. The benefits are related to less damage to the soft tissues, reduced blood loss, and motion preservation. However, further studies are needed to determine the effectiveness of the described surgical strategy.
