The Anatomical Boundaries and Endoscopic Technique of Posterior Cervical Key-Hole Foraminotomy

Posterior cervical foraminotomy stands as a recognized decompressive intervention aimed at alleviating radiating symptoms in the arm, neck, and shoulder stemming from refractory cervical radiculopathy. Although it parallels the anterior cervical discectomy and fusion (ACDF) in application, its endoscopic iteration boasts pronounced merits, especially when juxtaposed with ACDF and conventional open foraminotomy. Such benefits are attributed to reduced tissue insult and diminished postoperative discomfort. In this segment, the authors delineate contemporary advancements made in enhancing the endoscopic posterior cervical foraminotomy procedure. Moreover, they furnish an abundant array of intraoperative endoscopic depictions capturing surgically pertinent landmarks and anatomy, supplemented by their radiographic analogs.
