The first experience of total sacral endoprothesis with an individual implant after total sacrectomy (a rare clinical case)

Bone sarcomas are one the rarest types of malignant tumors comprising only 0.2–1 % of oncological diseases. Chondrosarcoma is the 3^rd most common bone sarcoma. This tumor is characterized by low sensitivity to drug and radiological treatment. According to literature data, the current golden standard of bone chondrosarcoma treatment is en bloc radical surgical resection with preservation of clean resection margins. However, common for this tumor location in the pelvic bones can pose difficulties at the stage of surgical planning.

The article presents a clinical case of surgical treatment of sacrum G₂ chondrosarcoma in the volume of total sacrectomy with defect replacement using a personalized implant manufactured using a 3D printer and with lumbosacral stabilization.
