Since morphometric data on the upper end of the humerus from Indian anatomical samples are scarce, this study was undertaken with reference to orthopedic surgery. The aim was to determine the length, width and depth of the bicipital groove and to find the incidence of a supratubercular ridge of Meyer in an Indian population.
The study included 104 unpaired dry humeri (48 right side and 56 left) which belonged to the anatomy laboratory of our institution. The length, width and depth of the bicipital groove were measured with a digital vernier caliper. The data were tabulated as mean ± SD and statistically compared between the right and left sides.
The mean length, width and depth of the bicipital groove were 84.6 ± 10.9 mm, 8.5 ± 2.3 mm and 4.4 ± 1.8 mm, respectively, which corresponded to 27.8% of the total length, 32.2% of the transverse width and 17% of the anteroposterior widh of the humerus, respectively. There was no statistically significant difference in these parameters between the left and right sides (p > 0.05). A supratubercular ridge of Meyer was seen in 24 (23.1%) of the humeri.
The study determined the morphometric parameters of the bicipital groove in an Indian population. We believe that this study will be an important reference for scientific research, and the details are also important for anthropologists and clinical anatomists.
由于来自印度解剖样本的肱骨上端形态测量数据稀缺，本研究针对骨科手术展开。目的是确定肱二头肌沟的长度、宽度和深度，并找出印度人群中迈耶氏结节上嵴的发生率。
本研究纳入了104根不成对的干燥肱骨（右侧48根，左侧56根），这些肱骨来自我们机构的解剖实验室。用数字游标卡尺测量肱二头肌沟的长度、宽度和深度。数据以平均值±标准差列表，并在左右两侧之间进行统计学比较。
肱二头肌沟的平均长度、宽度和深度分别为84.6±10.9毫米、8.5±2.3毫米和4.4±1.8毫米，分别相当于肱骨总长度的27.8%、横向宽度的32.2%和前后宽度的17%。这些参数在左右两侧之间无统计学显著差异（p>0.05）。在24根（23.1%）肱骨中可见迈耶氏结节上嵴。
本研究确定了印度人群中肱二头肌沟的形态测量参数。我们认为这项研究将为科学研究提供重要参考，其细节对人类学家和临床解剖学家也很重要。
