Degenerative changes such as facet hypertrophy and disc herniations alter these relationships, potentially leading to nerve root compression and cervical radiculopathy. Methods: This review synthesizes existing knowledge on the cIVF. Key imaging, cadaveric, and clinical studies serve as a foundation for this anatomic review. Results: We explore topics such as dynamic changes that affect foraminal size and their implications for nerve root compression, the relationship of the dorsal root ganglion to the cervical foramen, and the function and clinical significance of foraminal ligaments, arteries, and veins.

The absence of a neck brace after surgery is safe and does not affect the outcome of surgery. However, the effect on the incidence of AS is unclear. Methods: Patients who underwent anterior cervical single-segment ACDF between May 2020 and August 2021 were retrospectively analyzed. Participants were divided into brace group and nonbraced groups. The incidence of axial symptoms, cervical mobility, and postoperative quality of life were then compared between the 2 groups. Results: A total of 121 patients were included in this study: 62 in the brace group and 59 in the nonbraced group. There were no statistically significant variations observed in the overall demographic characteristics, including age, sex, body mass index, smoking status, and disease duration. The study findings showed that there was a significant decrease in the occurrence of axial symptoms among patients in nonbraced group, in addition to a considerable increase in cervical mobility 1 month following the surgery.
