Minimally invasive surgery for osteoid osteoma of the cervical spine using microendoscopic discectomy system

We report herein the case of an 18-year-old man who underwent endoscopic resection for an osteoid osteoma in the seventh cervical facet joint. The patient had experienced right neck pain for approximately one year, but no neurological abnormalities were noted. Cervical magnetic resonance imaging suggested an osteoid osteoma in the superior articular process of the seventh cervical vertebra. The tumor was resected microendoscopically. Operative time was 1 hour 29 minutes, and blood loss was 5 mL. During the two years since surgery, the patient has remained pain free with no cervical spine instability. We thus propose microendoscopic surgery for osteoid osteoma developing in a posterior element of the cervical spine is a potentially effective operative procedure.
