(I) Treatment principles Repositioning, fixation, functional exercise and anti-osteoporosis treatment are the basic principles of osteoporotic fracture treatment. In addition to the above principles, individualized treatment plans should be formulated according to the fracture site, fracture type, severity of osteoporosis and general condition of the patient to choose surgical treatment or conservative treatment for osteoporotic fractures of the extremities. For those who need surgical treatment, minimally invasive or less invasive repositioning and fixation techniques should be preferred, and relatively strong fixation devices in osteoporotic conditions should be used, with intramedullary nails and locking splints being good choices. Gently operate during surgery to reduce soft tissue injury, prevent excessive stripping of the periosteum, and protect the blood flow of the bone. For those with severe bone defects, bone grafting or bone cement, calcium sulfate and other materials can be used to strengthen the bone. Functional exercise is performed early after surgery to improve the function of the affected limb and prevent re-fracture.
