The most serious complication of osteoporosis is osteoporotic fracture. Fractures caused by osteoporosis seriously threaten the physical and mental health of the elderly and affect their quality of life, with high rates of disability, death and medical care costs, and are second only to cardiovascular diseases in importance. Among osteoporotic fractures, spine fractures, hip fractures and distal radius fractures are the most common. 1, causes, patients with osteoporosis have reduced bone mass, impaired bone microstructure, destruction of bone trabeculae, thinning of cortical bone, increased bone fragility, and stress below the fracture threshold, which leads to an increased risk of bone fracture. The occurrence of fracture is closely related to the reduction of bone density, which is significantly reduced in patients with osteoporosis. 2, the occurrence of causative factors, osteoporotic spine fractures most often occur without a large external force, such as in the twisting body, holding objects, opening windows, coughing or riding in a car vibration and other daily movements. The pain worsens suddenly at the onset, some patients (20%) have no pain, and some patients experience spontaneous fractures without any external force. Hip fractures and distal radius fractures are mostly caused by falls. 3. Morbidity, the incidence of fractures in men increases from the age of 65 years, while in women it keeps increasing from the age of 45 years. Females account for 85% of all fractures. The lifetime risk of various osteoporotic fractures is estimated to be 30% to 40% for women and 10% to 15% for men. Fractures occur at relatively fixed sites 4. Fractures are more likely to occur in the thoracic and lumbar spine (vertebral compression fractures), hip (proximal femur fractures), distal radius (Colles fractures) and ankle bone.
