Most primary benign tumors of the spine (e.g., osteoid osteoma, osteoblastoma, Langerhan’s histiocytosis) are curable with curettage. A few primary benign tumors have a high rate of local recurrence or can cause severe localized bone destruction (e.g., aggressive osteoblastoma, giant cell tumor of bone, aneurysmal bone cyst) and thus require more extensive resection. These tumors need to be considered for complete resection or in-lesion resection supplemented with local therapeutic approaches (e.g., bone cement, embolization, radiotherapy) to expand the resection borders. The overall success rate of surgical treatment for benign tumors is 86-100%. The outcome of surgical treatment of primary malignant tumors of the spine depends on the surgical approach and the surgical boundaries achieved. The 5-year survival rate after curettage of primary malignant tumors of the spine is 0%. the Iowa study showed a 5-year survival rate of 75% after complete resection. In this study, the 5-year survival rate after incomplete resection of malignant tumors was 18%.
