Design Factors Affecting the Fixation of Cervical Disc Replacements

This study presents the first quantification of micromotion, representing initial fixation, in cervical disc arthroplasty. Further, findings were generally consistent with clinical literature regarding device migration. This study has identified device-specific trends that may influence micromotion in vivo. These findings or methodology can be utilized to identify successful devices for patients or offer valuable insights into future cervical disc designs.
