If tectorial membrane damage what likely to occur
Answers
The tectorial membrane is the superior extension of the posterior longitudinal ligament (Fig. 5-17). It begins by attaching to the posterior aspect of the vertebral body of C2. It then crosses over the odontoid process and inserts onto the anterior rim of the foramen magnum (specifically the upper region of the basilar part of the occipital bone, or clivus). The tectorial membrane has superficial and deep fibers. The deep fibers have a median band that extends all the way to the basilar portion of the occipital bone. Two lateral bands of deep fibers pass medially to the atlanto-occipital joints before attaching to the occiput. The superficial fibers extend even more superiorly than the deep fibers and blend with the cranial dura mater at the upper region of the basilar part of the occipital bone (clivus). This ligament limits both flexion and extension of the atlas and occiput (Standring et al., 2008).
