Outcome of avulsion fractures in the foot after supination trauma: A systematic review.
Synthesis in European journal of trauma and emergency surgery : official publication of the European Trauma Society, 2025. 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
purposeAvulsion fractures of the foot after supination trauma are frequently encountered at the emergency department. Despite their high incidence, the prognosis of these fractures remains largely unknown. Moreover, evidence-based treatment recommendations are lacking and treatment decisions are primarily guided by expert-opinion. Our purpose is to provide an overview of the prognosis for these fractures.
methodsA systematic review was performed using the Medline and Embase databases to search for studies that reported on clinical outcome ≥ 6 months after an avulsion fracture of the foot after supination trauma.
resultsSeven avulsion fracture-types were identified and included in the search. Seventeen studies were included. Three studies focused on avulsion fractures of the anterior process of the calcaneus, and 14 focused on avulsion fractures of the base of the fifth metatarsal. Average number of cases was 41 (range 6-102). Average follow-up duration from fracture date was 22.6 months (range 6-206). Clinical outcome scores (AOFAS/Karlsson) indicated a favorable outcome for most patients of both fracture-types. However, both fracture-types had a subgroup with less favorable outcomes as all lower limits of the reported ranges were below normative.
conclusionLimited data is available on the clinical outcome (≥ 6 months) of fractures of the anterior process of the calcaneus and fifth metatarsal, both seem favorable. However, for both fracture-types there appears to be a subgroup with substantial persisting complaints. For 5 out of 7 avulsion fracture-types of the foot after supination there is insufficient data available in literature to provide patients with an adequate prognosis. LEVEL OF EVIDENCE: Therapeutic Level III, systematic review containing retrospective cohort studies.
