====== Vertebral body replacement ======


[[Vertebral body replacement]] (VBR) using CFR PEEK cages represents a legitimate surgical strategy that opens a variety of improvements-especially in patients in need of postoperative radiotherapy of the spine and MRI-based follow-up examinations

Design variations of [[expandable cage]]s for [[vertebral body]] [[replacement]] do not show any significant effect on the biomechanical results. There was no significant difference found, between the biomechanical properties of expandable and non-expandable cages. After corporectomy, isolated implantation of expandable cages plus anterior plating was not able to restore normal stability of the motion segment. As a consequence, isolated anterior stabilization using cages plus LCDCP should not be used for vertebral body replacement in the thoraco-lumbar spine
