Osteoporosis can occur in all parts of the body, and the bones of osteoporotic patients are brittle and prone to fracture. The common clinical sites of osteoporosis are as follows: 1, thoracic and lumbar spine: patients are prone to fractures of the lumbar and thoracic spine after weight-bearing, or even several vertebrae at the same time, such as compression fractures of the thoracic and lumbar spine, which can occur in severe cases after coughing; 2, hip: patients can have bilateral hip fractures at the same time, or two unilateral fractures; 3, distal forearm: postmenopausal women are prone to forearm distal fracture.
