The fibula is a long bone located at the lateral aspect of the leg. Diaphysis of fibula is supplied by one or more nutrient arteries through an opening referred to as the nutrient foramen. Mor-phometric studies of the nutrient foramina of fibulae are very sparse in literature.
This cross-sectional descriptive study was conducted on 51 dry adult human fibulae housed in the department of anatomy, AIIMS, New Delhi. Total fibular length along with the number and location of all nutrient foramina present were recorded. Foraminal indexes (FI) of the fibulae were calculated as well.
The study revealed that the average length of fibulae was 35.48 ± 1.76 cm. 94% fibulae had a single nutrient foramen and 6 % had two. In fibula with single foramen, the most common location was on the medial crest (50%), followed by between medial crest and posterior border (35%), between the medial crest and interosseous border (8%) and on posterior border (6%). Nutrient foramen was located in middle 1/3rd of shaft in 98 % and in inferior 1/3rd of shaft in 2 % of fibulae. The average foraminal index was 44.85 ± 6.67% with a range of 35.7 to 63.8%.
Most common location of nutrient foramen in fibula is middle 1/3rd of shaft on the medial crest with dual nutrient foramina in 6% of fibulae. These parameters show variability in different geographical location and population groups. These data may be helpful for anthropologists, forensic experts, radiologists and might guide in harvesting vascularised fibular bone graft.
腓骨是位于腿部外侧的长骨。腓骨干由一根或多根营养动脉通过称为营养孔的开口供应。腓骨营养孔的形态学研究在文献中非常少见。
这项横断面描述性研究在位于新德里 AIIMS 解剖系的 51 个成人干腓骨上进行。记录了所有存在的营养孔的总数和位置以及总腓骨长度。还计算了腓骨的孔指数（FI）。
研究表明，腓骨的平均长度为 35.48 ± 1.76cm。94%的腓骨有一个单一的营养孔，6%的有两个。在有单个孔的腓骨中，最常见的位置是内侧嵴（50%），其次是内侧嵴和后缘之间（35%）、内侧嵴和骨间缘之间（8%）和后缘（6%）。营养孔位于骨干中 1/3 段的 98%和骨干下 1/3 段的 2%。平均孔指数为 44.85 ± 6.67%，范围为 35.7 至 63.8%。
腓骨营养孔最常见的位置是内侧嵴骨干中 1/3 段，6%的腓骨有双营养孔。这些参数在不同的地理位置和人群中存在差异。这些数据可能对人类学家、法医专家、放射科医生有帮助，并可能指导带血管腓骨骨移植的采集。
