Osteolytic bone destruction refers to the destruction of the normal structure of bone due to pathological factors, bone resorption and disappearance, and the loss of bone structure and bone mass in areas with normal bone structure, called osteolytic bone destruction. Common causes include acute injury, long-term inflammatory stimulation, local ischemic changes, as well as infections, tumors, and systemic metabolic diseases, which can easily lead to abnormal bone metabolism and also produce bone resorption and osteolysis, for example, acute injury leads to local blood circulation disruption, and the damage to the bone mass will result in corresponding osteolysis, but the area of this condition is not very large, and only a small amount of osteolysis is produced locally in the fracture injury. Generally, it can heal well after treatment and recovery. Osteolytic destruction of tumor is due to tumor invasion and destruction of bone, resulting in bone resorption and replacement of the original location by tumor tissue, resulting in pathological changes.
