    Introduction: Although many bones of the human skeleton show the sex-, age-, and race-related differences, the distinctive morphology of the human rib bone makes it of utmost interest from anatomical, anthropological, and forensic point of view. The human first rib bone is one of the most informative bones in the human body. Morphometry of the rib bone is important for the anatomist as well as for the anthropologist for population studies. Moreover, specimen identification and sex determination from skeletal remains have great importance in many forensic medicine and related investigations. Materials and Methods: In the present study, a total of 20 dry rib bones of unknown sex and without any gross abnormality were collected from the Department of Anatomy, Saveetha Dental College, Chennai, for evaluation. With the help of Vernier caliper, the measurements such as the length, breadth, and diameter of rib bone were measured. The results obtained were analyzed, tabulated, and represented graphically. Results: In male, the average total length of the first rib on the right side was found to be 67.28 ± 2.34 and on the left side, it was 66.43 ± 3.42. In female, on the right side, it was 61.32 ± 1.6 and on the left side, it was 63.85 ± 1.56. In male, the average of ventrodorsal breadth of the first rib on the right side was found to be 21.57 ± 2.93 and on the left side, it was 20.4 ± 1.62. In female, on the right side, it was 18.5 ± 2.84 and on the left side, it was 17.43 ± 1.79. The mean angle of curvature of the right and left rib in male was 45.5° and 46.2°. In female, it was 41.5° and 42.8° on the right and left side. Conclusion: There are no much studies in literature for comparing the angle of the first rib between the right and left sides for Indian population. The present study was an initial step in estimation of the angle which can be used for estimating sexual dimorphism. Further researches on the first rib can add to the information and help the forensic anthropologists to identify the sex of an individual.
