Abstract

We present a rare case of a patient who underwent complete microendoscopic excision of an osteoid osteoma, which induced radiculopathy without nerve root compression. A 20-year-old man presented severe right groin pain that was temporarily relieved by nonsteroidal anti-inflammatory drugs. A computed tomography (CT) scan showed typical features of a nidus located in the inferior cortex of the right L3 pedicle. We performed surgery using a posterior microendoscopic approach. We drilled vertically along the line of the cortex of the caudal pedicle using a high-speed drill. After identifying the tumor, en bloc resection of the nidus was achieved. Immediately after surgery, pain in the right groin disappeared. A CT scan showed that most of the right L3 pedicle remained. This minimally invasive technique preserves spinal structures, including the facet and pedicle, and is a viable option for the treatment of spinal osteoid osteomas located close to vital structures.
