The stiffness in flexion and extension increased Purpose Few finite element studies have investigated with all HS models, except for the extension stiffness changes in cervical biomechanics with various prosthesis with ACDF/ACDR. The facet stresses between the index design parameters using hybrid surgery (HS), and none have and infra-adjacent level in ACDR/ACDF were significantly investigated those combined different HS strategies. The aim greater than those in the intact model . The stresses on the of our study was to investigate the effect of ball-and-socket BS-5 UHMWPE core were greater than the yield stress. prosthesis geometry on the biomechanical performance of Conclusion The core radii and position did not significantly the cervical spine combined with two HS constructs. affect the moments, ROM, and facet stress in extension.
