ABSTRACT

Objective: To describe the technique of total sacrectomy through a posterior-only approach, discussing indications, technical aspects, complications, and oncological outcomes available in the literature. Methods: Technical report based on detailed surgical description and narrative literature review. Expected results: The posterior-only approach may reduce operative time, intraoperative blood loss, and morbidity compared to the combined approach. Conclusion: Total sacrectomy via a posterior-only approach with the modified Cathedral reconstruction is a feasible and safe alternative in selected cases of primary malignant sacral tumors.
