Abstract

Background: The fibula is a long bone located at the lateral aspect of the leg. Its diaphysis is principally nourished by one or more nutrient arteries entering the shaft through an opening referred to as the nutrient foramen. The present findings on the morphometrics of the foramen may be helpful to forensic experts, radiologists and clinicians for diagnosis and management of various bony conditions. Materials and Methods: This was a descriptive cross sectional study conducted on fifty dry adult human fibulae collected at the Department of Anatomy, Chitwan Medical College from June to September 2020. Total fibular length along with the number and location of all nutrient foramina present were recorded. Foraminal index of the fibula was calculated as well. Results: The study revealed that the average length of Nepalese fibulae was 34.1 ± 1.9 cm. Eighty-eight percent fibula had a single nutrient foramen, 4 % had two and 8 % had none. The most common location was between the medial crest and posterior border (63%, in fibula with single foramen), followed by the medial crest (30%) and between the medial crest and interosseous border (7%). The average foraminal index was 44.01 ± 7.9 % with a range of 34.9 to 65.7 %. Conclusion: Single nutrient foramen located at the middle third on posterior aspect was the most common finding. Regional data on the number and location of the foramina would be useful to forensic experts and clinicians for various diagnostic and treatment purposes.
腓骨营养孔的变异及其临床意义
背景:腓骨是位于腿外侧的一根长骨。其骨干主要由一条或多条营养动脉滋养,这些营养动脉通过称为营养孔的开口进入骨干。本研究结果对法医专家、放射科医生和临床医生诊断和治疗各种骨疾病有一定的帮助。材料和方法:这是一项描述性横断面研究,对2020年6月至9月在Chitwan医学院解剖学系收集的50块干成人腓骨进行了研究。记录腓骨总长度以及所有营养孔的数量和位置。计算腓骨椎间孔指数。结果:尼泊尔人腓骨平均长度为34.1±1.9 cm。88%的腓骨只有一个营养孔,4%的腓骨有两个营养孔,8%的腓骨没有营养孔。最常见的位置是内侧嵴与后缘之间(63%,在腓骨单孔),其次是内侧嵴(30%)和内侧嵴与骨间缘之间(7%)。平均孔指数为44.01±7.9%,范围为34.9 ~ 65.7%。结论:单一营养孔位于后侧正中三分之一是最常见的。关于椎间孔数目和位置的区域数据对法医专家和临床医生用于各种诊断和治疗目的是有用的。
