Spinal stabilization by using crossed-screw anterior-posterior fixation after multisegmental total spondylectomy for thoracic chondrosarcoma - Case report

The authors describe the case of a 41-year-old man with high-grade chondros arcoma who presented with a paraspinous mass extending into three thoracic vertebrae (T10-12). Crossfixed long anterior and posterior instrumentation was placed after three complete spondylectomies (T10-12). This technique au gments spinal stability with an outrigger effect by using crossfixators pla ced between paired dorsal rods, as well as between the anterior and posteri or hardware components. This technique may be used as an alternative when m ultiple vertebrae or all three spinal columns are involved by radioresistan t malignant tumors in patients in whom there is a relatively long life expe ctancy.
