All patients with (impending) fractures of the long bones due to bone metastases and an operation indication will be asked to participate in the OPTIMAL cohort and provide patient reported outcomes. In addition, they will be informed about the PORT trial. Post-operatively, shortly before discharge from the hospital, they will be asked for informed consent for the PORT trial by the treating physician or a researcher. This assures a waiting period of 3-7 days between information and consent. Patients are informed that they are free to decide whether they wish to participate in the trial and will receive written information in addition to oral information. If patients do not wish to participate in the trial, they will receive standard care (which is post-operative radiotherapy in most cases). The first post-operative questionnaire will be sent 4 weeks after surgery.
