Thespecificaimsofthesymposiumare:1) to review recent advancements for resections at the cer-

vical, thoracolumbar spine and sacrum;2) identify promising directions for future resection and seg-

mental spinal defect reconstruction techniques;3) outline different biomechanical features of implant systems

and complex instrumental reconstructions;4) promote an interchange of ideas and stimulate collabora-

tive investigations between international spine surgeon community;

5) encourage all colleagues who are involved in the care of spine tumor patients to study options for management of lesions which previously have been considered as non-resectable.
