Abstract

Cervical disc arthroplasty (CDA) attempts to preserve normal motion at adjacent segments and in doing so may decrease the incidence of adjacent segment degeneration in comparison with cervical arthrodesis. Since 2006, the United States Food and Drug Administration (FDA) has approved seven CDA prosthetic devices for surgical management of symptomatic cervical spondylosis and disc herniation (seven for 1-level disease and two for two-level disease). Motion-preserving CDA has showed great promise with equivalent quality-of-life outcomes in many long-term comparative studies. Currently, follow-up duration of up to 10 years is available from some of the FDA trials comparing CDA to arthrodesis. In general, study findings have consistently demonstrated that both techniques result in significant clinical improvement by roughly 3 months post-op and that improvement may be maintained at final follow-up. Overall, there exists robust data to support CDA as a viable alternative to arthrodesis in select patients. However, complications such as heterotopic ossification have been reported. In this chapter, we review CDA, with an emphasis on highlighting the published long-term outcomes and complications for this motion-preserving operation in comparison with arthrodesis.
