Three-dimensional anatomical position of rotatory center in cervical rotatory and local manipulation / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the three-dimensional anatomical position of the rotatory center in cervical rotatory and local manipulation.</p><p><b>METHODS</b>A three-dimensional model was constructed based on CT data from cadaveric specimens of axial spinous process deviation. Cervical rotation was simulated on this model, and the graphic outcome was analyzed.</p><p><b>RESULTS</b>The rotatory center of this model was at the dens axis, not at the apex of the axial spionus process, and the angle of rotation exceeded observable angle.</p><p><b>CONCLUSION</b>The new concept of anisotropic rotation of the cervical vertebrae should be established and its principles must be comprehended in clinical practice of cervical rotatory manipulation.</p>
