Ethnic origin plays an important role in bone morphometry. Studies examining the influence of coracoid process have focused primarily on adults and have not included people from diverse Asian ethnic backgrounds. Our goal was to explore ethnic differences in morphometry of coracoid among Asian population. We performed morphometric measurements of coracoid process on cadaveric shoulders and shoulder CT scans from 118 specimens. The cadaveric sample included Indian (46%), Chinese (27%), and Myanmarese (27%) subjects, while the CT scans sample included Chinese (67%) and Malay (33%) subjects. The morphometric measurements were performed using digital caliper and software developed at Golden Horses Health Sanctuary (GHHS). In the Indian cadaveric shoulders, the coracoid process is better developed than the other groups with the exception of the tip width of coracoid process. There are significant differences in almost all measurements ( < 0.05) between the ethnic groups. On the other hand, the morphometry of coracoid process from CT scans data is bigger in Chinese than Malay subjects when stratified by sex ( < 0.05). Moreover, in all morphometric measurements, the females had smaller measurements than males ( < 0.05). Understanding such differences is important in anatomy, forensic and biological identity, and orthopaedic and shoulder surgeries.
种族起源在骨形态测量学中起着重要作用。研究喙突影响的研究主要集中在成年人身上，尚未纳入来自不同亚洲种族背景的人群。我们的目标是探讨亚洲人群中喙突形态测量的种族差异。我们对118个标本的尸体肩部和肩部CT扫描进行了喙突的形态测量。尸体样本包括印度人（46%）、中国人（27%）和缅甸人（27%），而CT扫描样本包括中国人（67%）和马来人（33%）。形态测量使用数字卡尺和金马健康保护区（GHHS）开发的软件进行。在印度尸体肩部中，除了喙突尖端宽度外，喙突比其他组发育得更好。不同种族之间几乎所有测量值均存在显著差异（<0.05）。另一方面，按性别分层时，CT扫描数据中中国人的喙突形态测量值比马来人更大（<0.05）。此外，在所有形态测量中，女性的测量值均小于男性（<0.05）。了解这些差异在解剖学、法医和生物识别以及骨科和肩部手术中很重要。
