“…One was the direct visual examination of the bone fusion, and the other was its radiological analysis. Several researchers performed a direct visual examination of bone specimens extracted from cadavers to evaluate the manubriosternal junction (MSJ) fusion [1,[17][18][19]. Another study was evaluated from a longitudinal section of the sternum through the midline [20].…”

The objectives of this study were to evaluate the manubriosternal joint (MSJ) to estimate the minimum chronological age of complete fusion, and how changes in this joint influence age estimation. The study also focused on investigating the calcification patterns of the second costal cartilage (SCC), as they may be related to age. Between January and September 2020, individuals between 30 and 80 years of age, who underwent chest tomography at our institution, were listed by sex and divided into five groups according to age with intervals of 10 years. Twenty patients from each age group and sex were randomly selected, and 200 patients were evaluated. The relationship between age and changes in MSJ and SCC was evaluated. The incidence of complete fusion did not differ significantly between the 30 and 80 age groups. A significant difference was found between the age groups and MSJ degeneration (p < 0.001). The degree of MSJ degeneration and calcification in SCC significantly increased with age, but the range was wide. These values might be used to support traditionally accepted age‐estimation methods but not as independent indicators of specific age ranges.

“…2 Sometimes experts face a problem even in identifying whether the skeletal remains are of human or not. 3,4 Identification can become more difficult during mutilation of body parts and decomposition. 1,5,6 In these cases of dubious identity, fine differences also assume importance and identification has to be done from remnants.…”

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.
