Osteoporosis Piebald

Osteoporosis piebald What is osteoporosis Osteoporosis is a systemic skeletal disease characterized by a decrease in bone mass, a violation of the microarchitecture of bone tissue, and, as a consequence, the risk of developing fractures due to minimal traumatic load. It manifests itself as an expansion of the network of bone marrow spaces, thickening of the cortical layer of bone. X-ray examination also reveals wear of the cancellous bone and defects in its trabeculae. The development of osteoporosis leads to an expansion of the perimeter of the metaphyseal cartilage of the diaphysis.

Most often occurs in women of post-castration age, much less often in men of older age groups suffering from endocrine pathology, death of large osteoblastic zones of more active hematopoietic zones. In addition, risk factors for the development of osteoporosis include occupational hazards, smoking, and prolonged immobilization with a reduction in the load on the skeletal system. There are primary and secondary osteoporosis. Primary occurs due to insufficient activity of osteoblasts (cells from which bone cells are formed) in the spine or heads of the femurs, vertebrae of the pelvis and ribs, which leads to the development of osteopenia - the appearance of a slight decrease in the volume of bone tissue (more than 1% compared to the norm for a given sex and age). An increased incidence of secondary osteoporosis is observed in diseases of the liver, kidneys and gastrointestinal tract, as well as hyperthyroidism, long-term treatment
