“…In harmony with results of the present work was study of Changani et al (2014) for determination of sex from sternal measurements by CT in Indian population found that the manubrium length, sternal body length, manubrium width and combined length of manubrium and sternal body were found to be larger in male than females and the difference was statistically significant.…”

Sex determination is an important step in personal identification which can be done from bones examination either from their metric measurements or radiograph images especially in difficult identification as dismemberments, mutilations and explosions. The present study was designed to assess the possibility of sex determination from sternal measurements by multislice computed axial tomography (MSCT) and generate statistical equations that can be used to determine sex from sternum in Upper Egypt persons. This study was performed on one hundred and sixty healthy living Upper Egypt persons (80 males and 80 females) of age 18-80 years old during MSCT investigation of the chest region, in department of radiodiagnosis in Assiut University hospital after informed consent. Fourteen sternal measurements were taken including manubrium length, sternal body length, combined length of the manubrium and sternal body, sternal index, manubrium width at tip, width and base, sternal body width at articulation with 2 nd , 3 rd , 4 th , 5 th and 6 th ribs and two virtual angles of sternum. First angle lies between two intersected virtual lines made along the lateral aspect of the upper part of the sternal body and the lateral aspect of the manubrium. Second angle lies between two virtual lines drawn along the lateral margins of the lower part of sternal body and xiphoid process. The data were analyzed statistically. Results of this study demonstrated that the male measurements showed higher statistical significant values than females measurements except sternal index. Use of the multiple and simple regression equations of relation between sternal measurements and sex demonstrated that the total body length was the most significant parameter for sex prediction. The discriminant function analysis revealed correct sex prediction in known Upper Egyptians by 93%. The multivariant logistic regression can give correct sex prediction in unknown Upper Egyptians by 85.4%. This study concluded that sex determination can be done through sternal measurements including the virtual sternal angles, the MSCT is a trustful method for bone measurement during forensic investigation and sex prediction from measurements of all sternal parts is higher than those from single part.

“…Hyrtl's rule 23,25 was applied which states that SI >50 in female and <50 in male. The identification point (IP) 20,21,23,26,29 was determined by the lowest value of a variable in males and highest value for the same in females.…”

Introduction: The comprehensive goal in forensic anthropology is the identification of skeletal remains for which researchers are constantly working to produce methods that are as accurate as possible. Because of distinct sexual dimorphism, bones of the pelvis and skull are preferred; however, when these bones are unavailable other bones like sternum have to be used as it holds a great deal of sexual dimorphism. Objective: To evaluate sexual dimorphism in the metric parameters of the sternum through MDCT images amongst Nepalese adults. Materials and Methods: Sternal dimensions of 105 study participants (62 male and 43 female) were measured using Computed Tomography (CT) images from Radiology Department of Dhulikhel Hospital. An independent t test was performed to assess the strength of association between different variables and genders. Differences were considered significant at P < 0.05. ROC curve analysis was done to determine the discriminating power of variables for sex determination. Result: The different measurements of sternal lengths were significantly greater in male than females(p<0.001) except Sternal Index which was found to be higher in female (p<0.001). Despite this difference in mean, most of the sterna were in overlapping zone. The limiting point of 126 was determined for total sternum which could correctly classify majority of sternum. Using ROC curve the mesosternum and total sternum were found to be most accurate (>95%) in sex determination. Hyrtl’s law could classify 91.9% of the male and Ashley’s rule of 136 could 97.67% of the female. Conclusion: Hence this study made an effort in sexing the sternum in Nepalese population amongst which mesosternal length and total sterna length were found to be best estimators of sex whereas manubrium length and sternal index were not found to be satisfactory.
