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.

Case 1. Computed tomography images. Preoperative (A), Postoperative (B) and one-year follow-up (C) computed tomography images. Pin-point extirpation of the nidus without excessive bone resection (B) and its remodeling (C) was observed. No tumor recurrence was detected.

Figure 1: Case 1. Computed tomography images. Preoperative (A), Postoperative (B) and one-year follow-up (C) computed tomography images. Pin-point extirpation of the nidus without excessive bone resection (B) and its remodeling (C) was observed. No tumor recurrence was detected.

Mentions: A 40-year-old man suffered from localized left lower back pain with a 3-year history. The pain deteriorated gradually, particularly during night time. His sleep was constantly disturbed by unremitting pain during the previous year. He visited an orthopaedic clinic where OO of L2 was identified by CT (Fig. 1A) and magnetic resonance (MR) imaging. Nidus was localized in the subchondral region of the left superior articular process of L2 (Fig. 1A). Treatment with non-steroidal anti-inflammatory drug (NSAID) was effective, however, this treatment was halted due to a drug-induced gastric ulcer.
