Although osteoporosis has been de? ned as “a metabolic bone disease characterized by low bone mass and microarchitectural deterioration of bone tissue leading to enhanced bone fragility and a consequent increase in fracture risk,” it is not clear that osteoporosis represents a single disease as much as a similar response of bone to different pathophysiologies. In the 1940s Fuller Albright and colleagues recognized “osteoporosis of old age” and distinguished it from osteoporosis associated with the postme- pausal state, as well as from osteoporosis from disuse, osteoporosis from malnutrition, and other forms of osteoporosis. He nevertheless pointed out that it was unclear how much of osteoporosis is due to old age per se, in view of the fact that “in many cases osteoporosis of disuse, of malnutrition, of the postmenopausal state and of senility are inseparably superimposed. ” In this volume, Duque and Kiel have gathered an international panel of experts to highlight the unique features of senile osteoporosis and cons- eration of this disease spans the very basic through the clinical and the epidemiologic. As an organ which harbors stem cells, bone may clearly in? uence not only its own regeneration but also the regeneration of other tissues, notably the hematopoietic system.

This new edition includes the most up-to-date information about the pathophysiology and new therapeutic alternatives for osteoporosis of advanced age. It is written by investigators (clinicians and basic scientists) in the field of aging bone research.It was just recently that a new syndrome, osteoporosis of advanced age, was recognized as a new entity with its own pathophysiology and potential treatments. Unfortunately, and despite the fact that hip fractures are mostly a consequence of this process, and apart from the first edition of this book, there are few publications about this subject. The first edition of this book demonstrated that there is a need to understand the particular features of osteoporosis in older persons, which is the main aim of this book. The institutions where the authors are affiliated are highly recognized as the main centers in aging bone research. As an innovation, the second edition includes some aspects of muscle and bone interaction focusing of the impact of age-related muscle loss (sarcopenia) on the pathogenesis of falls and fractures in older persons. As in the previous edition, this book is expected to be the reference guide for geriatricians, gerontologists, and bone biologists as well as medical trainees in order to understand the mechanisms of senile osteoporosis with a practical approach to the treatment of its consequences.
