The vertebral location of a lesion compatible with an osteoid osteoma often requires a marginal en bloc resection. Our objective is to present the use of 3D printing technology for the development of specific cutting guides that achieve a safe and complete resection of an L1 osteoid osteoma. We present the case of a 13-year-old male who underwent surgery for an L1 osteoid osteoma, detailing the preoperative planning assisted by 3D technology, the surgical technique using 3D printed cutting guides, a real model of the lumbar spine, and the postoperative control. Conclusion: Before the surgical indication of a lesion compatible with an osteoid osteoma in the spine, we must decide between the possibility of an open intralesional resection or percutaneous and marginal en bloc resection. Different methods can be used for the intraoperative location of the lesion. In our department, we use 3D technology for preoperative planning of multiple acute and post-traumatic pathologies. This allows us to be precise and safe in the identification of intraoperative resection margins, minimizing the removal of healthy tissues and avoiding postoperative instability.
