Abstract

The present study assessed the correlation between the stature and scapular measurements from both sides in order to develop population-specific regression equations to estimate the stature from measurements of the scapula in a contemporary Northern Indian population individually for the left and right sides. A total of 597 cadavers underwent postmortem multidetector computed tomography and subsequent medicolegal autopsy in our department between August 2021 and August 2022. Two hundred samples (100 males and 100 females) were randomly collected based on inclusion and exclusion criteria. Six linear anthropometric measurements of the scapula from either side were measured using the 3D volume-rendered technique by an electronic cursor. Each anthropometric measurement showed a significant difference between males and females (p < 0.05). Regression analysis was applied to match the taken measurements against stature. The accuracy to predict stature ranged from 3.99 to 4.94 cm for males and from 4.49 to 5.27 cm for females, respectively. Left-sided measurements were better predictors of stature than the right side in both genders. The results of this study indicate that scapular measurements could be useful to estimate the stature of Northern Indian individuals, particularly in scenarios of disaster victim identification lacking long bones, which are considered to be better predictors to date.

利用三维体积渲染技术,通过回归方程对印度北部人口的肩胛骨测量结果进行身材估算。
本研究评估了身材与两侧肩胛骨测量值之间的相关性,以便建立针对特定人群的回归方程,根据对当代印度北部人群左右两侧肩胛骨的测量值估算身材。2021 年 8 月至 2022 年 8 月期间,本部门共对 597 具尸体进行了死后多载体计算机断层扫描和随后的法医尸检。根据纳入和排除标准随机收集了 200 份样本(男性 100 份,女性 100 份)。使用三维体积渲染技术,通过电子光标测量两侧肩胛骨的六个线性人体测量值。每项人体测量结果均显示男性和女性之间存在显著差异(P < 0.05)。采用回归分析法将测量结果与身材相匹配。男性预测身材的准确度为 3.99 至 4.94 厘米,女性为 4.49 至 5.27 厘米。左侧测量结果比右侧测量结果更能预测男女的身材。这项研究的结果表明,肩胛骨测量值可用于估计北印度人的身材,尤其是在缺乏长骨的灾民身份鉴定中,因为迄今为止,长骨被认为是更好的预测指标。

期刊介绍: Medicine, Science and the Law is the official journal of the British Academy for Forensic Sciences (BAFS). It is a peer reviewed journal dedicated to advancing the knowledge of forensic science and medicine. The journal aims to inform its readers from a broad perspective and demonstrate the interrelated nature and scope of the forensic disciplines. Through a variety of authoritative research articles submitted from across the globe, it covers a range of topical medico-legal issues. The journal keeps its readers informed of developments and trends through reporting, discussing and debating current issues of importance in forensic practice.
