Computer-Assisted Navigation Full Visualization Spinal Endoscopic Surgery for Lumbar Vertebral Osteoid Osteoma.

backgroundOsteoid osteoma is a benign osteogenic tumor that occurs mostly in the femoral stem, while osteoid osteoma occurring in the lumbar vertebral body is a relatively rare case. To minimize treatment-related complications, a computer-assisted navigation fully visualized spinal endoscopy was used. Ultimately, the pathology was diagnosed as osteoid osteoma. CASE PRESENTATION: We report a 19-year-old adult male with low back pain that worsened at night and CT, MRI imaging showed an abnormal signal shadow at the posterior margin of the lumbar vertebral body. Due to the proximity of the lesion to the spinal canal and adjacent to the nerve roots, it was difficult to precisely localize the lesion by purely endoscopic or open procedures, and if necessary, the resection of surrounding tissues had to be expanded, causing unnecessary damage to the surrounding tissues. Therefore, we choose computer-assisted navigation fully visualized spinal endoscopy to perform the treatment.

conclusionIn this case, we report an osteoid osteoma that occurs less frequently in the lumbar vertebral body. Using computer-assisted navigation with fully visualized spinal endoscopy, we successfully resected the osteoid osteoma at the posterior margin of the L3 vertebral body preoperatively by computer-planned path with intraoperative visualization endoscopy, minimizing the damage to spinal stability. Computer-assisted navigation with visualization endoscopy provides a more precise and minimally invasive approach to the treatment of osteoid osteoma of the spine.
