Sternum is one of the skeleton parts which have frequently congenital anomalies and variations are commonly used by researchers in determining sex. We evaluated the morphological characteristics and sex-related changes of the sternum in adult individuals using multidetector computed tomography in our study.
Two hundred adults (103 female and 97 male) aged between 18 and 87 years were evaluated. Utilising the morphological characteristics of the sternum based on the multislice images; length, width and the thickness of manubrium, length, width and the thickness of corpus sterni, total length of sternum, sternal angle, sternal index (SI), length of the xiphoid process, the thickness of xiphoid process, the number of indents of xiphoid process were measured and a total of 20 parameters were evaluated by adding age, height and weight to these variables.
The mean length of the manubrium, the length of corpus sterni, the length of total sternum, SI, sternal angle were found in females 46.7 ± 5.1, 86.6 ± 9.7, 133.1 ± 1.1, 54.47 ± 10.0 and 163.75 ± 5.79; in males 51.2 ± 6,102.4 ± 13.3, 154.1 ± 13.1, 50.11 ± 10.02 and 162.21 ± 6.17, respectively. We found that Hyrtl's Law and SI did not provide adequate accuracy for sex determination in our patients. It has been detected that the length of the manubrium alone is not helpful for individual samples. Total length of the sternum was found to be more reliable than the length of the manubrium and the length of corpus sterni. We determined sternal cleft and sternal foramen as 0.5% and 3.5%, respectively.
We suggest that the morphometric standards cannot be universally applied and can demonstrate individual differences. The standard rules must be implemented for every population.
胸骨是骨骼中先天性异常较为常见的部位之一，研究人员在性别判定中常用到其变异情况。在本研究中，我们使用多排螺旋计算机断层扫描评估了成年个体胸骨的形态特征及与性别相关的变化。
对200名年龄在18至87岁之间的成年人（103名女性和97名男性）进行了评估。根据多层图像利用胸骨的形态特征；测量了胸骨柄的长度、宽度和厚度，胸骨体的长度、宽度和厚度，胸骨的总长度，胸骨角，胸骨指数（SI），剑突的长度，剑突的厚度，剑突的凹陷数量，并通过将年龄、身高和体重添加到这些变量中，共评估了20个参数。
女性的胸骨柄平均长度、胸骨体长度、胸骨总长度、SI、胸骨角分别为46.7±5.1、86.6±9.7、133.1±1.1、54.47±10.0和163.75±5.79；男性分别为51.2±6、102.4±13.3、154.1±13.1、50.11±10.02和162.21±6.17。我们发现，在我们的患者中，希尔特尔定律和SI在性别判定方面的准确性不足。已检测出仅胸骨柄长度对个体样本并无帮助。胸骨总长度被发现比胸骨柄长度和胸骨体长度更可靠。我们确定胸骨裂和胸骨孔的发生率分别为0.5%和3.5%。
我们建议形态测量标准不能普遍适用，可能会显示个体差异。必须为每个群体实施标准规则。
