The hip bone (os coxae, innominate bone, pelvic bone or coxal bone) is a large irregular bone, constricted in the center and expanded above and below. In some vertebrates (including humans before puberty) it is composed of three parts: the ilium, ischium, and the pubis
property
Differences in bone properties between noncases and incident hip fracture cases followed similar trends in both men and women, were located at compatible regions, and showed heterogeneity in the spatial distribution of their magnitude, with focal regions showing greater differences.
Most of the regions with a significant interaction between fracture group and sex showed differences of greater magnitude in men than in women between noncases and hip fracture cases, with different spatial distributions for all bone properties, with the exception of cortical bone thickness.
While most of these regions showed better bone quality in male than in female cases, female cases showed higher vBMD in the principal compressive group and higher endotrabecular vBMD at several regions, including the anterior, posterior, and lateral aspects of the proximal femur.
"These findings indicate the value of these image analysis techniques by providing unique information about the specific patterns of bone deterioration associated with incident hip fracture and their sex differences, highlighting the importance of looking to men and women separately in the assessment of hip fracture risk," the authors conclude.
