Abstract：
BACKGROUND: Nutrient foramen (NF) is a hole on the long bones that allows the passage of the nutrient artery. The vasculature of the bone is very important for fracture healing and vascularized bone grafting. Therefore, information about the location and number of NFs is important for surgical and clinical practice. The clavicle is the most commonly fractured bone. The aim of this study was to analyze the relationship between the location and number of NFs on the clavicle and other clavicle parameters.
METHODS: This study was performed on 86 dry clavicles of contemporary adult individuals without age and gender records. Some clavicle parameters and NF parameters were measured and the relationship between them was analyzed. Measurements were performed using a digital caliper.
RESULTS: Most of the clavicles had a single NF. There was a positive correlation between DFant/DFpost (distance between NF and anterior border/distance between NF and posterior border) and vertical thickness of sternal end (VTs), vertical thickness of thinnest point (VTt) and clavicular thinnest point index (CIt) in all cases (p < 0.05). Sagittal thickness of acromial end (STa), vertical thickness of clavicle (VTc), sagittal thickness of clavicle (STc) and sagittal thickness of thinnest point (STt) were associated with NF counts. The most common localization of NFs was type 2. The NFs were mostly located in the inferior position.
CONCLUSIONS: Relationships between the number and morphometric characteristics of NFs and some clavicle parameters were determined. It was suggested that the knowledge of the number and morphometric characteristics of NFs is important for the protection of the nutrient artery in orthopedic surgery applications.

摘要：
背景：营养孔（NF）是长骨上的一个孔，允许营养动脉通过。骨的脉管系统对于骨折愈合和血管化骨移植非常重要。因此,有关NFs的位置和数量的信息对于手术和临床实践很重要.锁骨是最常见的骨折。本研究旨在分析锁骨上NFs的位置和数量与其他锁骨参数之间的关系。
方法：这项研究是对没有年龄和性别记录的当代成年人的86个干燥锁骨进行的。测量了一些锁骨参数和NF参数，并分析了它们之间的关系。使用数字卡尺进行测量。
结果：大多数锁骨具有单个NF。DFant/DFpost（NF与前边界之间的距离/NF与后边界之间的距离）与胸骨端垂直厚度（VT）之间呈正相关，所有病例的最薄点垂直厚度（VTt）和锁骨最薄点指数（CIt）（p<0.05）。肩峰端矢状厚度(STa),锁骨垂直厚度(VTc),锁骨矢状厚度（STc）和最薄点矢状厚度（STt）与NF计数相关。NFs最常见的定位是2型。NFs大多位于劣势。
结论：确定了NFs的数量和形态特征与一些锁骨参数之间的关系。有人建议，了解NFs的数量和形态特征对于在骨科手术中保护营养动脉很重要。
