Histo‐anatomy of the proximal femur in rats: Impact of ovariectomy on bone mass, structure, and stiffness

Hip fractures are the most devastating consequence of osteoporosis in humans. Since the ovariectomized (ovx) rat is a useful model of estrogen‐deficient osteoporosis, the purposes of this study were to describe the histo‐anatomical features of the rat hip and to determine changes in the proximal femur induced by ovariectomy to evaluate the use of this skeletal site for future bone studies.
