Transpedicular corpectomies are frequently used to perform anterior surgery from a posterior approach. Minimally invasive thoracolumbar corpectomies have been previously described, but these are performed through a unilateral approach. Bilateral access must be obtained for a circumferential decompression when using such techniques. The authors describe a technique that allows for a mini-open transpedicular corpectomy, 360° decompression, and expandable cage reconstruction through a single posterior approach. This is performed using percutaneous pedicle screws, the trap-door rib-head osteotomy, and a single midline fascial exposure. The authors describe this technique with intraoperative photos and a video demonstrating the technique.
