Abstract

Background: The present study is an attempt to estimate stature from the measurements   of Foramen Magnum using postmortem multidetector computed tomography (PMCT) in the North Indian population. Foramen Magnum Length (FML) and Foramen Magnum  Breadth (FMB) measurements for every skull were taken using the PMCT of 100 North Indian people.  Materials and Method: PMCT examination was performed using a 16-slice MSCT spiral scanner, Cannon Medic l Systems, results were evaluated with the Vitrea  software v.6.9.1. The images were viewed using Multiplanar Reconstruction and Volume Rendering technique (MPR-VRT). STAT, FML, andFMB were measured and analyzed  Results: The study population comprised 57 males and 43 females with a mean age  of 38.3 years, respectively. Regression analysis was used in stature estimation from FML   and FMB. The standard error of estimate (SEE) of the FML was 6.18 and FMB was 6.64 for   the combined population while SEE ranged from 4.77 to 5.21 cm for the male population  and 6.18 to 6.30 cm for the female population respectively.  Conclusions: This study is the first to provide a metric and statistical analysis of the  Foramen Magnum measurements in Northern India using PMCT and concluded that
stature estimation is highly possible with minimum SEE from the Foramen Magnum  measurements. Furthermore, the equations derived to estimate stature in this study can  How to cite this article:  Karthi Vignesh Raj K, Abhishek Yadav, Sudhir K Gupta et al.
