Chapter 11 - Total Disc Arthroplasty
Spine Technology Handbook, pp 303-370

Abstract
This chapter summarizes early total disc replacement designs and current cervical and lumbar disc replacements. The chapter focuses on three historical disc replacement designs evaluated in patients: Fernström spheres, the AcroFlex artificial disc, and the Charité artificial disc. From a historical and implant design perspective Fernström was the first pioneer of disc arthroplasty. His work introduced the notion that a motion-preserving interbody prosthesis might possibly avoid undesirable complications of spine fusion procedures. Fernström's work also provides some evidence, albeit extremely limited, that metallic disc replacement components were biocompatible when implanted as bearing materials in the intervertebral disc space to articulate against the end plates. The AcroFlex artificial disc represents a major evolutionary step in the conceptual design of total disc arthroplasties, especially when juxtaposed against the much simpler design of the Fernström sphere. The Charité design, formally known as the SB Charite artificial disc by its inventors, basically consists of two metallic end plates fixed to the adjacent vertebral bodies, which articulate against a central core fabricated from ultrahigh molecular weight polyethylene (UHMWPE).
