Guidelines for the diagnosis and treatment of osteoporosis

  Osteoporosis (OP) is a systemic bone disease characterized by low bone mass and destruction of bone microarchitecture, leading to increased bone fragility and susceptibility to fracture (World Health Organization, WHO).  In 2007, the National Institutes of Health (NlH) proposed that osteoporosis is a disease of the bone and iliac system characterized by decreased bone strength and increased fracture risk, with bone strength reflecting two major aspects of the skeleton, namely bone mineral density and bone mass. The disease can occur in different genders and at any age, but is more common in postmenopausal women and older men. Osteoporosis is divided into two major categories: primary and secondary. Primary osteoporosis is divided into postmenopausal osteoporosis (type I), senile osteoporosis (type II), and idiopathic osteoporosis (including adolescent type). Postmenopausal osteoporosis generally occurs within 5 to 10 years after menopause in women; senile osteoporosis generally refers to osteoporosis occurring after the age of 70 years in the elderly: and idiopathic osteoporosis mainly occurs in adolescents, the cause of which is still unknown.  Osteoporosis is a health problem with clear pathophysiological, psychosocial and economic consequences. A serious consequence of osteoporosis is the occurrence of osteoporotic fractures (fragility fractures), which are fractures that can occur with minor trauma or during daily activities due to decreased bone strength. Osteoporotic fractures greatly increase disability and mortality in the elderly.
