Abstract
Objective- Estimation of sex by pattern of calcification of first costal cartilage in North Indian Population.
Methods- The present study has been conducted in the “Department of Anatomy in collaboration with the Department of Forensic Medicine and Department of Radiology,PGIMS, Rohtak”.
The specimen consisted of 50 pairs of first ribs and manubrium from both sexes, aged between 15 and 30 years, in order to determine the pattern of calcification. Specimens were taken from “cases of medico-legal autopsies” performed in the “Department of Forensic Medicine” with the legal heir of the deceased's consent, and they were radiographed in the “Department of Radiology”.
Results- In the present study, calcification was observed in cartilages of both sexes aged above 16 years. Type A (marginal bracket), type A 1 (marginal linear) and type B (central) pattern were found more frequently in females on both sides with an estimated predictive value of 66.32%, 50.27% and 100% respectively. Type C (mixed) pattern occurred more frequently in males on both sides with estimated predictive value to be 100%.
Conclusion- There was no evidence of bilateral asymmetry between the calcification patterns on the right and left sides. This means that the first costal cartilage's calcification displays a clear pattern in respect to the sex at issue.
