The aims of this study are to define the coracoid process anatomy in a Malaysian population, carried out on patients in Hospital Serdang with specific emphasis on the dimension of the base of coracoid process which is important in coraco-acromial (CC) ligament reconstruction, to define the average amount of bone available for use in coracoid transfer, and to compare the size of coracoid process based on gender and race, and with findings in previous studies. Fifteen pairs of computed tomography (CT) based 3-dimensional models of shoulders of patients aged between 20 to 60 years old were examined. The mean dimensions of coracoid were measured and compared with regards to gender and race. The data were also compared to previously published studies. The mean length of the coracoid process was 37.94 ± 4.30 mm. Male subjects were found to have larger-sized coracoids in all dimensions as compared to female subjects. The mean tip of coracoid dimension overall was 19.99 + 1.93mm length × 10.03 + 1.48mm height × 11.63 + 2.12mm width. The mean base of coracoid dimension was 18.96 + 3.71mm length × 13.84 + 1.76mm width. No significant differences were observed with regards to racial denomination. The overall coracoid size measurements were found to be smaller compared to previous studies done on the Western population. This study may suggest that Malaysians have smaller coracoid dimension compared to Caucasians. The findings further suggest that the incidence of coracoid fracture and implants pull out in Malaysian subjects may be higher.
本研究的目的是确定马来西亚人群的喙突解剖结构，以马来西亚沙登医院的患者为研究对象，特别强调喙突基部的尺寸，这在喙肩（CC）韧带重建中很重要；确定可用于喙突转移的平均骨量；并根据性别和种族比较喙突的大小，以及与先前研究结果进行比较。对15对年龄在20至60岁患者基于计算机断层扫描（CT）的肩部三维模型进行了检查。测量了喙突的平均尺寸，并按性别和种族进行比较。数据还与先前发表的研究进行了比较。喙突的平均长度为37.94±4.30毫米。发现男性受试者在所有维度上的喙突尺寸都比女性受试者大。喙突尺寸的平均尖端总体为19.99 + 1.93毫米长×10.03 + 1.48毫米高×11.63 + 2.12毫米宽。喙突基部尺寸的平均长度为18.96 + 3.71毫米×13.84 + 1.76毫米宽。在种族方面未观察到显著差异。与先前对西方人群的研究相比，发现喙突的总体尺寸较小。这项研究可能表明，与白种人相比，马来西亚人的喙突尺寸较小。研究结果进一步表明，马来西亚受试者中喙突骨折和植入物拔出的发生率可能更高。
