Osteoporosis is a common disease characterized by reduced bone mass, microarchitectural degeneration of bone tissue, and an increased incidence of fragility fractures. A fragility fracture, or osteoporotic fracture, is a low-energy fracture caused by a fall from a standing position or lower height, for example, that can occur with minor violence during daily activities and is the most serious consequence of osteoporosis. Osteoporotic fractures can occur in all parts of the body, including the hip, leg, wrist, pelvis, spine gui, ribs, humerus, clavicle, radius and ulna. Foreign scholars classify osteoporotic fractures into four categories: proximal femur fractures, spine fractures, the remaining major fractures (including pelvic fractures, distal femur fractures, proximal tibia fractures, multiple rib fractures and proximal humerus fractures) and minor fractures (including distal upper extremity and distal lower extremity fractures such as forearm fractures, metacarpal or wrist fractures, rib fractures, distal lower extremity fractures, foot and clavicle fractures. Osteoporotic fractures of the extremities refer to fractures occurring in other parts of the body than the spine and pelvis as described above, with hip fractures and distal radius fractures being the most common.
