Abstract

Cervical disc arthroplasty techniques were developed as an alternative to fusion in order to preserve natural motion and reduce the risk of adjacent segment degeneration in the appropriately selected patients with cervical myeloradiculopathy. These arthroplasty implants must provide stability, preserve physiologic motion, and replicate the kinematic signature of the natural disc. There are currently eight cervical arthroplasty implants approved by the Food and Drug Administration (FDA) for use in the United States. The majority of approved implants follow a metal on polyethylene ball-in-socket or saddle-type design. Over the past decade, there has been an explosion of cervical arthroplasty implant designs each with their own advantages and disadvantages. The purpose of this chapter is to review the biomechanics and kinematics of the natural cervical disc. We will also review available in vivo and ex vivo literature on novel elastomeric compression, hydraulic, and next-generation ball-in-socket cervical arthroplasty designs.
