Abstract
Transforaminal endoscopic spine surgery is an emerging technique in spine surgery but offers two distinct challenges to spine surgeons looking to adopt it: 1) targeting spine pathology, and 2) understanding the endoscopic anatomy visualized through the endoscope. Intraoperative CT guided navigation is also an emerging technique in spine surgery that is becoming widely adopted for its benefits in assisting surgeons in localizing pathology and guided spine instrumentation placement. In this technical note, we describe a technique that utilizes intraoperative CT guided navigation concomitantly with a transforaminal endoscopic approach to decompress a Lumbar 4-5 foraminal heterotopic bone formation after an oblique lumbar interbody fusion. The addition of intraoperative CT guided navigation proved both beneficial in targeting the pathology during the procedure as well as assurance that the pathology was resolved by offering postoperative CT visualization of the decompressed neural foramen.
