The 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.
A 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.
The 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.
Zone 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.
腓骨位于小腿外侧，在胚胎期骨骼生长和早期骨化过程中通过滋养动脉获得重要营养。本研究旨在评估来自南印度人群的干燥腓骨滋养孔的方向、距离、位置、数量和孔指数。
一项描述性横断面分析纳入了63根来自坦达勒姆萨维塔医学院及医院解剖学系的干燥成人人类腓骨。记录了腓骨长度、血管孔位置、数量和方向等参数。对形态学数据和孔指数进行了统计分析。
腓骨平均长度为34.68±2.11厘米。在这些腓骨中，88.88%有单个滋养孔，4.76%有两个滋养孔，6.34%没有滋养孔。大多数单个孔位于内侧嵴（66.66%），其次是内侧嵴与后缘之间（20.63%）。滋养孔主要位于II区（87.30%），其次是III区（11.11%）和I区（1.58%）。在方向上，85.71%向下，14.28%向上。平均孔指数为40.85±6.78，范围为32.57至56.25。
II区，特别是在内侧嵴上，是腓骨血管孔最常见的位置。6.34%的病例出现双孔。这一精确的解剖学知识对包括人类学家、法医专家、放射科医生、整形外科医生和骨科医生在内的各种医学专业人员具有重要价值，特别是在涉及带血管腓骨移植的手术中。
