死者身高推估為法醫人類學中重要研究領域，其所得的資訊可以提供人身鑑別更多線索，縮小死者身分調查範圍。過往研究中，主要以長骨為研究對象，但在近年來大災難等事件中，常見碎屍塊與骨骸殘片而缺乏長骨。本研究目的為藉由易於辨識的第二頸椎結合電腦斷層影像技術進行身高推估公式研究，以期未來在骨骸殘片遺體推估身高時能有國人合適之推估公式應用。本研究採用回溯性研究，量測第二頸椎之齒突頂點至椎體前端最低位點、錐體前端最低點至棘突頂點與棘突頂點至齒突頂點之最長長度。得到單一特徵位點長度、混合兩種與三種特徵位點長度組合身高推估計算公式共6組公式，總計18組身高推估公式。在不分性別組別、男性組別的全部身高推估公式與女性組別兩組單一特徵位點身高推估公式，其結果推估身高皆與原始身高無顯著差異。本研究建立之台灣人第二頸椎身高推估公式，在法醫實務上不分性別的遺體或骨骸屍等狀況，最適合採用之推估公式為錐體前端最低點至棘突頂點單一特徵位點身高推估公式，其效度分析結果最佳。

Human body height prediction from residual bones is an important field in forensic anthropology. It may provide information in individual identification and can apply to judicial investigation. In previous studies, researchers focused on the association between long bones and body height. However, we may obtain only fragments of long bones and small bones for body height prediction in mass disaster. This study aimed to develop formulas to estimate adult body height of different genders by using computed tomography data of human second cervical vertebrae of Taiwanese. The results may apply to body height prediction with residual bones of anonymous corpses in forensic casework. This research was a retrospective study. The measurements were taken at three points and three lengths were obtained: the top of the dens to the anterior-inferior point of the vertebral body (DA); the anterior-inferior point of the vertebral body to the posterior point of the spinous process (AS); the top of the dens to the posterior point of the spinous process (DS). In this study, 18 human height prediction formulas from second cervical vertebrae was established. There were no significant differences between the observed body heights of these subjects and the estimated heights of subjects in both-gender group and male group. However, in the female group, there were four formulas failed for body height prediction. In conclusion, we contrasted the formulas of Taiwanese body height from second cervical vertebrae by using computed tomography data. We recommend the use of AS formula in body height prediction for unknown-gender corpuses in forensic casework.
