Ligament deformation patterns of the craniocervical junction during head axial rotation tracked by biplane fluoroscopes

In vivo cervical vertebrae kinematic studies based on dual fluoroscopic imaging system measurement: A narrative review

“…This result may be attributed to the orientation of the articular facets of the zygapophyseal joints [ 16 ]. Zhou et al found that during axial rotation of the head, C0–C1, C1–C2, and the entire cranio-cervical junction (C0–C2) exhibited complex coupled segmental motion [ 24 ].…”

“…Researchers have utilized DFIS to study the characteristics of cervical ligaments during motion. Zhou et al found that during head rotation, each component of the transverse atlanta ligament, including the superior longitudinal band and inferior longitudinal band undergoes slight deformation [ 24 ]. The ipsilateral alar ligaments significantly lengthen, while the contralateral alar ligaments are compressed.…”

“…There are partial variations in studies involving healthy individuals. These differences may arise from various factors such as different physiological curvatures of the cervical spine, variations in participant age (reflecting different degrees of degeneration) [ 16 ], and differences in participant gender [ 24 ]. Scholars suggest that age and gender significantly impact cervical spine anatomy and kinematics [ 66 ].…”
