In addition to the primary tumor, bone is also a common site of metastasis for other malignant tumors, such as breast cancer, prostate cancer, thyroid cancer, bladder cancer, lung cancer, kidney cancer, and malignant melanoma. Bone metastases can involve all bones of the body and can cause bone pain, pathological fractures, compression of nerves and blood vessels, and even paraplegia. In the past, the traditional view was that once metastasis occurred, surgical treatment was of little significance. However, with the improvement of treatment technology, the prognosis of many tumors such as breast cancer, prostate cancer, thyroid cancer and kidney cancer has been significantly improved and life expectancy has been significantly extended. Therefore, when bone metastases appear, treatment should be actively carried out to improve the quality of life of patients. For patients with bone metastases with longer expected survival, reasonable surgery can achieve the following purposes: 1. treatment and prevention of pathological fractures. 2. release of spinal cord and nerve compression. 3. relief of local pain caused by bone metastases. 4. removal of some lesions. 5. plastic surgery and rehabilitation. Personalized surgical treatment for patients with bone metastases can help patients restore limb function, facilitate care or restore self-care, and improve quality of life.
