AbstractChanges in bone structure as a function of age have been studied by simple inspection, x‐ray imaging, stereo‐photography, deep field optical microscopy, circularly polarised light microscopy, and scanning electron microscopy (SEM), including both topographic and compositional backscattered electron (BSE) imaging modes.

The decline of tissue function in ageing is a consequence of many changes in the gene expression and other extrinsic factors. The molecular mechanisms underlying these changes are heavily investigated with focus on regulation of time-lapse gene expression.

AbstractChanges in bone architecture and metabolism with aging increase the likelihood of osteoporosis and fracture. Age‐onset osteoporosis is multifactorial, with contributory extrinsic and intrinsic factors including certain medical problems, specific prescription drugs, estrogen loss, secondary hyperparathyroidism, microenvironmental and cellular ...

Reviews in Clinical Gerontology, 1998
In Europe, vertebral fracture incidence has increased 300–400% for women and more than 400% for men during the last 30 years. These data are age-adjusted and therefore highlight that there is a decrease in bone mass or bone quality from generation to generation.

Pathophysiology and Aging of Bone [PDF]
, 2003 Human aging is a complex process which, as a result of multiple genetically programmed mechanisms as well as stochastic events, leads to accumulation of damaging alterations in vital cellular functions. A variety of in vitro studies indicate that aging is associated with an overall decline in protein synthesis and protein turnover as well as with an ...

Clinical Orthopaedics and Related Research, 1982
A survey was done of aging changes in compact and trabecular bone. During the past decade, noninvasive methods have demonstrated similar results for compact bone in large samples. Aging decreases of 3%/decade begin at about age 40 in both sexes and continue, but in women, an additional loss occurs after menopause, bringing their total rate of decrease ...

On age-dependent bone remodeling
Journal of Biomechanics, 2020A number of previous studies have investigated the possibilities of modelling the change in density of bones. Remodeling can be formulated at the constitutive or the kinematic level. In this work we introduce a formulation for the density growth process which takes not only the mechanical stimulus into account but also the influence of age on the ...

The purpose of this article has been to summarize the existing body of literature on the changes in the function of muscle and bone that occur as a consequence of aging. Throughout this article, the importance of distinguishing between aging and disuse has been a recurring theme.

Skeletal development in average healthy individuals is maximal at age 25 in women and at age 30 to 35 in men. However, there are significant racial differences, skeletal mass being greater in black than in white individuals. This difference appears best accounted for by increased muscle mass in blacks.
