En-bloc resection of spine tumors is difficult to achieve compared to extremities tumors for anatomical reason. Several surgical techniques have been described, such as combined multiple surgical approaches or an enlarged single posterior approach. These demanding strategies correlate with high rate of intraoperative/postoperative complications. The current case is about a patient treated with a single posterior-lateral surgical approach to perform hemivertebrectomy of L5 for a single grade 2 chondrosarcoma metastasis (WBB 2-5/b-c). Usually, L5 hemivertebrectomy requires a combined surgical approach to preserve L5 root. The final solution was to perform a T-shape skin incision: a longitudinal branch centered on the vertebral spine and a transverse branch on the iliac crest. This approach allowed osteotomy of the ipsilateral iliac crest, achieving sufficient view to preserve L5 root and vessels anteriorly; the same osteotomy was used to create a bone autograft to reconstruct the residual part of L5. Finally, cryotherapy was used in order to increase the adequacy of surgical margins. A L3-S1 arthrodesis is assembled to achieve stability of the system. Surgical time was 5 hours, no nerve roots have been sacrificed nor any other intraoperative complications occurred. This surgical technique had never been described before in literature.
