Total uncinectomy of the cervical spine with an osteotome: technical note and intraoperative video

Restricted access

Total uncinate process resection or uncinectomy is often required in the setting of severe foraminal stenosis or cervical kyphosis correction. The proximity of the uncus to the vertebral artery, nerve root, and spinal cord makes this a challenging undertaking. Use of a high-speed burr or ultrasonic bone dissector can be associated with direct injury to the vertebral artery and thermal injury to the surrounding structures. The use of an osteotome is a safe and efficient method of uncinectomy. Here the authors describe their technique, which is illustrated with an intraoperative video.

ABBREVIATIONS PLL = posterior longitudinal ligament; UP = uncinate process; VA = vertebral artery.
