The recent progress in oncologic management of patients with metastatic disease has permitted a significant improvement of their life expectancy. Many of these patients will suffer from complications related to bone metastasis. Unfortunately an orthopaedic treatment is seldom offered to them, mainly because of the misconception that this would not bring them any benefice. However these patients are often good candidates for an orthopaedic management, which objectives are to relieve pain and to re-establish their quality of life. The available surgical techniques are well described and the management protocols are clearly defined, as are the expectable complications and the errors that must not be done.
