Nutrient foramina of human fibula: morphometric analysis and clinical relevance.
Article in Journal of bone and mineral metabolism, 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
backgroundThe fibula, situated laterally in the leg, receives vital nutrition through nutrient arteries during embryonic bone growth and early ossification. This study aims to assess the direction, distance, location, number, and foraminal index of nutrient foramina in dry fibulae from the South Indian population. MATERIALS AND
methodsA descriptive cross-sectional analysis involved 63 dry adult human fibulae sourced from the Department of Anatomy, Saveetha Medical College and Hospital, Thandalam. Parameters like fibula length, location, number, and direction of vascular foramina were recorded. Statistical analyses were performed on morphometric data and foraminal index.
resultsThe mean fibula length was 34.68 ± 2.11 cm. Among the fibulae, 88.88% had a single nutrient foramen, 4.76% had dual foramina, and 6.34% lacked nutrient foramina. Most single foramina were found on the medial crest (66.66%), followed by between the medial crest and posterior border (20.63%). Nutrient foramina were primarily located in Zone II (87.30%), followed by Zone III (11.11%) and Zone I (1.58%). Directionally, 85.71% pointed downward, while 14.28% pointed upward. The mean foraminal index was 40.85 ± 6.78, ranging from 32.57 to 56.25.
conclusionZone II, particularly on the medial crest, was the most prevalent location for vascular foramina in the fibula. Dual foramina occurred in 6.34% of cases. This precise anatomical knowledge is valuable for various medical professionals, including anthropologists, forensic experts, radiologists, plastic surgeons, and orthopedic surgeons, especially in procedures involving vascularized fibular bone grafts.
