Which age group is most likely to show significant differences in iliac crest fusion between genders?

The age group of 17-19 years is significant for studying iliac crest fusion because this period coincides with the later stages of skeletal maturation, where notable differences in bone development between genders become more pronounced. During these years, males typically experience a later maturation of their skeletons compared to females, which can lead to distinct differences in the ossification of the iliac crest.

In females, fusion tends to occur earlier due to earlier onset of puberty and associated growth spurts. By the ages of 17 to 19, many females will have completed fusion, while many males may still be undergoing this process. This biological timing creates a clear window for observing and studying the differences in iliac crest fusion between genders, making this age range particularly relevant for forensic assessments and anthropological studies related to sexual dimorphism.

In contrast, the other age groups may not reveal the same degree of disparity. For instance, 13-15 years is often too early, as both genders are still in earlier stages of puberty where fusion may not yet be as evident. The ages of 16-18 can show some differences, but many individuals may still not have fully completed the fusion process. By 20-22 years, most individuals will have reached complete fusion
