The rapid development of society has also brought about various hazards, and the incidence of tumors is now increasing, and with the increasing number of various tumors, there are more and more patients with metastases. In the past, it was thought that tumor metastasis meant a death sentence, but now more and more evidence shows that tumor metastasis can be survived with tumor. The most common tumor metastases are lung metastases, liver metastases and bone metastases. Lung metastasis eventually affects breathing directly, and liver metastasis leads to internal organ failure, both of which are tricky and are often treated mainly with chemotherapy, radiotherapy and biotherapy. There are still more treatment options for bone metastatic tumors (including extremity and spine metastases), such as spine tumor excision and internal fixation, tumor scraping and internal fixation, tumor excision and prosthesis replacement, local radiotherapy, etc. The most common bone tumor tumors include: thyroid tumor, lung cancer, prostate cancer, breast cancer, gastrointestinal tumor, kidney cancer, etc.
