Locating the Instant Center of Rotation in the Subaxial Cervical Spine with Biplanar Fluoroscopy during In Vivo Dynamic Flexion-Extension.

Conclusions: The ICR in the cervical spine showed a trend of moving progressively more superiorly and anteriorly and the disc space overlapping the distribution circle of ICR increased along the lower motion segments except the C5-6 segment. These findings could provide a good basis for level-specific cervical arthroplasty designs. PMID: 31788173 [PubMed - in process]
