Stature estimation is an important process of biological profile analysis for the identification of skeletal remains. In forensic practice, non-long bones might be needed for estimating stature, in case long bones were not recovered or well preserved. This study developed the stature estimation model from dry sterna in a Thai population. The combined length of manubrium and mesosternum (CMM) was the best single stature estimation indicator for males and combined sex samples, whereas the sternal area (SA) was the best stature estimation indicator for females in our study. The best multiple regression analysis models of our study were stature equal 122.685+0.182 (CMM)+0.592 (intercostal length between the third and fourth ribs [ICL]) with a standard error of estimation (SEE) of 6.134 cm for males, stature equal 130.676+0.005 (SA) with SEE of 5.370 cm for females, and stature equal 79.412+0.342 (CMM)+0.506 (corpus sterni width at first sternebra [CSW])+0.794 (ICL) with SEE of 6.222 cm for unknown sex samples. The results indicated that a sternum can be used for estimating the stature of skeletal remains in a Thai population. However, these models might not be suitable for other populations, especially, in case the suspected stature is over the stature range in our study.
身高估计是生物特征分析中鉴定骨骼遗骸的一个重要过程。在法医实践中，如果长骨未找到或保存不佳，可能需要使用非长骨来估计身高。本研究建立了泰国人群干燥胸骨的身高估计模型。在本研究中，男性和混合性别人群的最佳单一身高估计指标是胸骨柄和胸骨体的联合长度（CMM），而女性的最佳身高估计指标是胸骨面积（SA）。本研究中最佳的多元回归分析模型为：男性身高=122.685 + 0.182（CMM）+ 0.592（第三和第四肋骨之间的肋间长度[ICL]），估计标准误差（SEE）为6.134厘米；女性身高=130.676 + 0.005（SA），SEE为5.370厘米；未知性别样本身高=79.412 + 0.342（CMM）+ 0.506（第一胸骨节处胸骨体宽度[CSW]）+ 0.794（ICL），SEE为6.222厘米。结果表明，胸骨可用于估计泰国人群骨骼遗骸的身高。然而，这些模型可能不适用于其他人群，特别是在疑似身高超出本研究身高范围的情况下。
