Anatomical Importance Between Neural Structure and Bony Landmark: Clinical Importance for Posterior Endoscopic Cervical Foraminotomy

Abstract

A prediction of the correlated position between the lateral dura edge and the V-point is essential for the PECF not to injure the neural structure. In the case of a performing the PECF at the C5-6 and C6-7 level in the old-aged patient, it should be considered the laterally moved dura edge, and more extended bony remove is needed for less neural structure damage.
