Bottom Line: Accordingly, establishment of an ideal less invasive surgical strategy for spinal OO remains yet unsettled.We illustrate the efficacy of a computed tomography (CT)-based navigation system in excising OO located adjacent to the facet joint of spine.We advocate a less invasive approach to spinal OO, particularly in an environment with an available CT-based navigation system.

ABSTRACT
Osteoid osteoma (OO) is a benign osteoblastic tumor. Its curative treatment is complete removal of the nidus, where intraoperative localization of the nidus governs clinical results. However, treatment can be difficult since the lesion is often invisible over the bony surface. Accordingly, establishment of an ideal less invasive surgical strategy for spinal OO remains yet unsettled. We illustrate the efficacy of a computed tomography (CT)-based navigation system in excising OO located adjacent to the facet joint of spine. In our 2 cases, complete and pin-point removal of the nidus located close to the facet joint was successfully achieved, without excessive removal of the bone potentially leading to spinal instability and possible damage of nearby neurovascular structures. We advocate a less invasive approach to spinal OO, particularly in an environment with an available CT-based navigation system.

Mentions: A 16-year-old man complained of right neck pain. A plain X-ray of the cervical spine at the initial consultation showed a slight torticollis. MR imaging revealed an inflammation/edema pattern at the right side of C2 lamina (Fig. 3) with the diagnosis of bone bruise. He enjoyed playing Judo, though he reported no preceding severe trauma. NSAID was effective during an early stage of his illness, though pain aggravated gradually.
