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.

Bone and fat connection in aging bone
Current Opinion in Rheumatology, 2008The fat and bone connection plays an important role in the pathophysiology of age-related bone loss. This review will focus on the age-induced mechanisms regulating the predominant differentiation of mesenchymal stem cells into adipocytes. Additionally, bone marrow fat will be considered as a diagnostic and therapeutic approach to osteoporosis.There ...

There must be few fields of clinical medicine that are subject to as much confusion as osteoporosis. The diagnosis in any particular case is frequently uncertain, and may vary from specialist to specialist. There are no agreed investigation protocols, for diagnosing osteoporosis and the treatment tends to be arbitrary and stereotyped.

Bone Age Assessment Based on Two-Stage Deep Neural Networks
International Conference on Digital Image Computing: Techniques and Applications, 2018Skeletal bone age assessment is a clinical practice to diagnose the maturity of children. To accurately assess the bone age, we proposed an automatic bone age assessment method in this paper based on deep convolution network.

Bone age assessment defined as the measure of skeletal development is most often used in pediatrics and forensics to estimate the true age of a person. It is usually done by comparing the left hand X-ray of a person with the hand radiographs in the standard atlas or based on local regions of interests (ROI) that include epiphyseal regions of the ...

Ageing and bone structure [PDF]
, 1993 Ageing causes substantial changes in both the structure and the mechanical properties of bone, i.e. quantity and quality18,31. Bone loss throughout life has been observed in so many different populations, that it is regarded as a universal feature of ageing, also called ‘physiological osteopenia’6,31,44.
