Abstract
ObjectivesThe cervical vertebrae are more durable than other skeletal components, and therefore may be the only remnants of a dead body. The present study aims to investigate the role of several linear dimensions of the second cervical vertebrae measured by Three-Dimensional Computed Tomographic Scanning (3D CT Scan) in height estimation of Iranian adult population. In this cross-sectional study, height determination was performed by measuring 15 indexes of the second cervical vertebrae. Indexes were obtained by screening cervical CT scan of 66 patients (33 males and 33 females) aged ≥ 18 years at Rasoul Hospital. Chi square, T student and logistic regression tests were used for statistical analysis. The significance level was considered to be < 0.05.ResultIn the total population, among the indexes for the second cervical vertebrae, the Max height of the axis (AMA) (r = 0.470, P = 0.0001), Max length of the axis (CMA) (r = 0.320, P = 0.007), and Sagittal max body diameter (DSMC) (r = 0.281, P = 0.019) had a strong and positive correlation with height. The results of this study showed the accuracy of linear dimensions of cervical vertebrae in determining the body height of the Iranian adult population.
Highlights
The results of this study showed the accuracy of linear dimensions of cervical vertebrae in determining the body height of the Iranian adult population
In this study, for the first time, the dimensions of the second cervical vertebrae were used in the determination of the height in the mature and living population of Iran using their cervical CT scan
The standard errors of the estimate were large. They showed the size of the C2 as measured with multidetector computed tomography (MDCT) images may be useful for stature estimation [11]
Summary
Since bones remain several years after death, the skeletal examination could be especially useful to identify those cases [1, 2]. Though in most of the times, we do not have long bones or they are fragmented, while smaller bones, The relationship between heights of people with spinal vertebrae morphology is one of the effective factors in identifying a person in forensic medicine. For this reason, in cases where only part of the body spine is available, the morphology of the vertebral column can explain the various skeletal features of a person, including his height. Each component of the spinal cord at any portion, especially in the cervical area, can be of great help in identifying height, especially in cases where it is not possible to assess height, such as severe traumas [3, 12–14]
