“…We used a CT imaging reference model because CT images are known to be highly accurate 1 , 13 , 14 , 23 . Previously, Lim et al 24 used CT images of two cervical spines to show that a 3D spinal motion analysis method was accurate within 1 mm of translation and 1° of rotation.…”

To validate the accuracy of Cone beam computed tomography (CBCT) cervical spine modeling with three dimensional (3D)-3D registration for in vivo measurements of cervical spine kinematics. CBCT model accuracy was validated by superimposition with computed tomography (CT) models in 10 healthy young adults, and then cervical vertebrae were registered in six end positions of functional movements, versus a neutral position, in 5 healthy young adults. Registration errors and six degrees of freedom (6-DOF) kinematics were calculated and reported. Relative to CT models, mean deviations of the CBCT models were < 0.6 mm. Mean registration errors between end positions and the reference neutral position were < 0.7 mm. During flexion–extension (F–E), the translation in the three directions was small, mostly < 1 mm, with coupled LB and AR both < 1°. During lateral bending (LB), the bending was distributed roughly evenly, with coupled axial rotation (AR) opposite to the LB at C1–C2, and minimal coupled F–E. During AR, most of the rotation occurred in the C1–C2 segment (29.93 ± 7.19° in left twist and 31.38 ± 8.49° in right twist) and coupled LB was observed in the direction opposite to that of the AR. Model matching demonstrated submillimeter accuracy in cervical spine kinematics data. The presently evaluated low-radiation-dose CBCT technique can be used to measure 3D spine kinematics in vivo across functional F–E, AR, and LB positions, which has been especially challenging for the upper cervical spine.

“…Flexion increases the foraminal height width and foraminal area. Extension decreases them [27,33,41]. After cervical retraction, dimensions of the cervical neural foramina show no significant change, except at C3-C4 [29].…”

“…Foraminal stenosis of the C5 nerve root indicated stenosis of the C5 intervertebral foramen (between C4 and C5) caused by improper alignment, facet hypertrophy, disc space narrowing, or bony spurs. [ 17 , 18 ] Determination of foraminal stenosis was based mainly on oblique views of cervical radiographs at the site of the affected shoulder (Fig. 3 ); other views were used for comparison.…”
