Free-Hand Pedicle Screw Placement Using a Ball Tip Widening Technique for Small Pedicles.
Article in Clinics in orthopedic surgery, 2025. 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
The purpose of this study was to assess the accuracy and validity of the "ball tip widening technique." We designed a retrospective analysis of 212 pedicle screws inserted in correction surgery for pediatric scoliosis, using posterior spinal instrumentation and fusion with pedicle screws at Seoul National University Bundang Hospital between July and August of 2021. The accuracy of pedicle screw placement was then classified using intraoperative computed tomography (CT; O-arm). Intraoperative CT revealed that 86.8% of pedicle screws (184 / 212) were placed in pedicle. The ball tip widening technique introduced in this study can enhance the accuracy of screw insertion into small pedicles. Furthermore, this technique may also be applied to lumbar surgery for degenerative conditions in the future.
