Lessons learned on cervical total disc replacement after 7-year follow-up

Cervical spine fusion was well adopted since the 1950s to stabilize, treat degenerative changes and reduce deformity. Various studies demonstrate that single-level ACDF do alter spinal kinematics and compromise global spinal motion. Along with critical clinical and scientific overview, arthroplasty technology was developed to maintain movement and reduce adjacent segment stress and degeneration. Here we point out to the success and the complications after our 7 years experience with PCM total disc replacement.
