Bone metastatic cancer with pathological fracture, the purpose of surgery is to relieve pain to restore limb function and improve life quality. The traditional surgical method is based on amputation, which is very traumatic for patients, slow in wound recovery and poor in function. At present, we adopt steel plate and bone cement to treat metastatic bone tumor in the limbs, which can effectively relieve pain, establish local “steel and bone cement” structure, preserve the limb, effectively prevent pathological fracture, and improve the patient’s quality of life. It is a simple and effective palliative and prophylactic treatment method, which is easy to operate, less traumatic, significantly shortens the hospitalization time, reduces the side effects of local radiotherapy, and satisfies the short-term efficacy with proper selection of surgical indications. In recent years, the Department of Bone Oncology has adopted the “reinforced bone cement” technique for limb preservation surgery and achieved good results. Since 2010, more than 80 patients have been successfully operated by this technique, which has relieved their pain and reduced hospitalization time and various complications.
