Osteosarcoma affecting the L3 vertebra in a 55-year-old man (Case 11). (A, B) Preoperative computed tomography (CT) scan showed the lesion within the L3 vertebra, right pedicle, and right lamina. Total en bloc spondylectomy, through a single posterior approach, was performed. (C, D) Extracted specimens included the posterior element and the anterior portion. (E) Titanium mesh filled with bone cement was used as anterior reconstruction, and a pedicle screw was applied in the posterior reconstruction. Shown is a postoperative radiogram demonstrating the correct alignment of instrumentation. (F) A CT study at 18 months after surgery demonstrated no relapse.
