Spinopelvic Fixation After Sacrectomy

Tumor resection and solid arthrodesis of the lumbosacral region of the spine are challenging. Tumors in this region as well as their surgical resection can significantly influence the biomechanics of the sacropelvis resulting in failure of axial load transmission. Therefore, to perform an oncologically and functionally optimal surgery, both the anatomical and biomechanical consequences must be carefully considered during preoperative planning.
