It is not uncommon to see the non union of the fractures in the long bones. Among the various reasons for the nonunion of the fractured bones, the nutrient artery plays an important role.
This study was aimed at analyzing the nutrient foramina in dry adult humerii ,with regards to the number, size and the location of the nutrient foramen with respect to the surfaces and the zones and its distance from the mid point of the humerus.
This was an analytical study. All the humerii from various medical colleges of the Vinayaka Missions University in Salem were included in the study. Those which were damaged and those which had pathological abnormalities were excluded. The following parameters were noted; namely, the length of the humerus, the number and the size of the nutrient foramen and the location of the nutrient foramen with respect to the surfaces and the zones of the humerus and its distance from the mid-point of the humerus were analyzed. The length of the humerus and the mid point of the humerus were measured by using the osteometric board, whereas the size of the nutrient foramen was measured by using various size of hypodermic needles. When more than one foramen was found, the larger one was taken as the dominant foramen and its size was measured. All the data were noted and the statistical analysis was done by calculating the mean, the range and the standard deviation.
Totally, 258 adult dry humerii were studied. The mean length of the humerii was 27.96 cm, with a SD of 2.18. The mean size of the nutrient foramen was 0.828 mm, with a SD of 0.26. The mean distance of th dominant nutrient foramen from the mid point of the humerus was 2.31 cm, with a SD of 1.25 cm. In majority of the humerii (86.43%), the nutrient foramen was located in the middle 1/3(rd) of the bone and in 13.57% of the bones, it was located in the lower 1/3(rd) of the bone. The location of the nutrient foramen in the anteromedial surface was 89.92%, that in the posterior surface was 8.53% and that in the anterolateral surface was 1.55%.
长骨骨折不愈合的情况并不少见。在骨折不愈合的各种原因中，滋养动脉起着重要作用。
本研究旨在分析干燥成人肱骨的滋养孔，包括滋养孔的数量、大小、相对于骨面和区域的位置以及其距肱骨中点的距离。
这是一项分析性研究。纳入了来自塞勒姆维奈亚卡使命大学各医学院的所有肱骨。排除有损伤和病理异常的肱骨。记录以下参数；即，分析肱骨的长度、滋养孔的数量和大小、滋养孔相对于肱骨表面和区域的位置以及其距肱骨中点的距离。使用骨测量板测量肱骨的长度和肱骨的中点，而使用各种尺寸的皮下注射针测量滋养孔的大小。当发现多个孔时，将较大的一个作为主要孔并测量其大小。记录所有数据，并通过计算平均值、范围和标准差进行统计分析。
共研究了258根成人干燥肱骨。肱骨的平均长度为27.96厘米，标准差为2.18。滋养孔的平均大小为0.828毫米，标准差为0.26。主要滋养孔距肱骨中点的平均距离为2.31厘米，标准差为1.25厘米。在大多数肱骨（86.43%）中，滋养孔位于骨的中1/3，在13.57%的骨中，它位于骨的下1/3。滋养孔在前内侧表面的位置为89.92%，在后表面的位置为8.53%，在前外侧表面的位置为1.55%。
