Abstract
PURPOSE OF REVIEW: There have been numerous published reports describing skeletal differences between males and females. The goal of this report is to describe recent findings to help elucidate remaining questions. RECENT FINDINGS: It is known that even in youth, there are sex differences in skeletal health. One recent report suggests these differences are evident at 6 years of age. With the availability of newer imaging techniques, specifically HRpQCT and microCT-3D, micro-architectural differences related to sex-differences have been studied. This has highlighted the importance of cortical porosity in describing possible sex differences in fracture risk. We have a better understanding of skeletal microarchitecture that highlights sex differences in both growth and aging that may relate to fracture risk, although more longitudinal studies are needed. Sex differences in microarchitecture, particularly cortical porosity may also be important in understanding any, as of yet unknown, sex differences in fracture reduction with treatment.
