Ultrasound-guided bone fulcrum lever rotation for fetal head malposition.
Article in Archives of gynecology and obstetrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 the efficacy and safety of applying the ultrasound-guided bone fulcrum lever rotation method during manual rotation of the fetal head in cases of labor dystocia due to fetal head malposition.
methodsThis retrospective study analyzed 109 parturients with persistent occiput posterior (POP) or occiput transverse (OT) positions in the second stage of labor, who delivered at a tertiary hospital in Jiangsu Province, China, between January 2024 and September 2025. Participants were divided into an experimental group (ultrasound-guided bone fulcrum lever rotation, n = 54) and a control group (conventional manual rotation, n = 55). Comparisons were made regarding the fetal head rotation success rate, the mode of delivery, and the neonatal outcomes.
resultsThe success rate of fetal head rotation was significantly higher in the experimental group compared to the control group (88.89% vs. 67.27%, P = 0.006). The rotation procedure time was shorter in the experimental group (P = 0.019), and the rate of spontaneous vaginal delivery was significantly higher (94.44% vs. 76.36%, P = 0.008). There were no significant differences in neonatal outcome indicators between the two groups.
conclusionIn this study, intrapartum ultrasound localization was combined with manual rotation manipulation for the management of cephalic dystocia. The results indicated that this combined intervention yielded better clinical efficacy than conventional manual rotation alone, and thus it holds high clinical application value.
