Biomechanics and materials of reconstruction after tumor resection in the spinal column.

We initially review the general biomechanical principles that should be considered in surgical reconstruction of spinal tumors. This will be further clarified by more detailed descriptions for individual spinal regions in the subsequent part of the article. In the case of patients with spinal metastases, especially in patients with a median survival time less than a few months, a thorough review of the risks and benefits regarding surgical intervention must be discussed with the patient. However, once the decision for surgery has been made, a biomechanically sound reconstruction should be performed to help restore or maintain the patient's mobility.
