Pulsed Electromagnetic Field (PEMF) Stimulation for the Treatment of Fifth Metatarsal Fracture Nonunion.
Article in Orthopedic reviews, 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
Background: Healing success for fifth metatarsal fracture nonunions is challenging and hindered by risk factors for nonunion. Pulsed electromagnetic field stimulation (PEMF) promotes bone healing and can help overcome biological deficiencies in patients at risk. Objective: The current study assessed the impact of PEMF treatment to promote successful bone healing in metatarsal nonunion. Methods: A multi-center, retrospective study was conducted to evaluate PEMF treatment for fifth metatarsal fracture nonunion. Subjects undergoing treatment and eligible for treatment with PEMF (PhysioStim™ device) were enrolled. Subjects were followed for up to 12 months to determine bone healing status determined by radiographic assessment. Subjects were assessed for healing status and impact of risk factors for nonunion. Results: Fifty-six (n=56) subjects were included in the analysis. Subjects were 89.3% female with a mean age of 59.7 years. Of the risk factors studied, 75.0% of subjects had at least 1 risk factor associated with compromised bone healing. PEMF treatment started shortly after the nonunion diagnosis, and the average time from nonunion diagnosis until successful healing was 154.7 days. Approximately 62.5% of subjects showed successful healing of their 5th metatarsal fracture by 4 months; 75.0% of subjects healed by 6 months; 91.1% of subjects healed by 12-months. The number of risk factors (up to 5 total per subject) was associated with longer heal times (p<0.02). Of the risk factors studied, only nicotine use was associated with longer healing times (p<0.03). Conclusion: Metatarsal nonunion subjects treated with PEMF achieved favorable time to healing despite having risk factors for compromised healing.
