C1 lateral mass screw insertion caudally from C2 nerve root - An alternate method for insertion of C1 screws: A technical note and preliminary clinical results

摘要

Background: C1 lateral mass screw was widely used for fixation of the upper cervical spine. However, massive bleeding from the C1-2 venous plexus is sometimes encountered. In this study, we proposed an alternate method for C1 lateral mass screw insertion, which involves insertion of the screws caudally from the C2 nerve root to reduce bleeding from C1-2 venous plexus.
