Pain: Low back pain or circumferential skeletal pain, increased pain or limited movement with increased load. Spinal deformity: There may be shortening of height and hunchback, spinal deformity and limited extension. Compression fractures of the thoracic spine can lead to thoracic deformity and affect cardiopulmonary function; fractures of the lumbar spine may alter the abdominal anatomy, leading to constipation, abdominal pain, bloating, decreased appetite, and a sense of premature fullness. Fractures: Fragility fractures refer to low-energy or non-violent fractures, such as those that occur as a result of daily activities. Common sites are the thoracic and lumbar spine, hip, distal radius and ulna, and proximal humerus. According to our statistics, the incidence of fractures in the elderly is 6.3% to 24.4%, especially in elderly women. In the United States, there are 15 to 20 million people suffering from osteoporosis and 1.2 million people suffer from fractures every year. The most frequent fracture sites are the hip, spine, and wrist, especially in women, where hip fractures occur 2 to 3 times more often than in men. The mortality rate one year after hip fracture is 12-20%, only 25% of patients can fully recover, 50% of patients need help to take care of their daily life, and another 25% of patients are completely unable to take care of themselves. Despite the many publicity reports on osteoporosis, the percentage of patients treated is still very low. The most vulnerable to osteoporosis are women over 55 years of age, and many women with osteoporosis do not make a diagnosis until clinical symptoms appear.
