With the acceleration of global aging, osteoporotic fractures (OPF) have become a significant public health issue threatening the health of the elderly, especially with a marked increase in fracture incidence among postmenopausal women and elderly men. This article systematically analyzes the pathological mechanisms of osteoporotic fractures, focusing on the key roles of osteoclasts and osteoblasts in fracture occurrence and healing. Overactivation of osteoclasts and dysfunction of osteoblasts are the main causes of delayed fracture healing and bone quality deterioration. Aging, oxidative stress, inflammatory responses, and estrogen deficiency, among other factors, influence osteoclast and osteoblast functions through various signaling pathways. To effectively treat osteoporotic fractures, this article summarizes the latest therapeutic strategies targeting osteoclasts and osteoblasts, including inhibition of osteoclast activity via the RANKL/RANK signaling pathway, promotion of osteoblast function with parathyroid hormone (PTH) analogs, and the potential application of gene therapy and nanotechnology in fracture treatment. In conclusion, precision treatment strategies are expected to accelerate fracture healing, improve bone quality, and significantly reduce the impact of osteoporotic fractures on patients’ quality of life and the socioeconomic burden. %K 骨质疏松性骨折， %K 病理机制， %K 破骨细胞， %K 成骨细胞， %K 治疗策略
