History

cervical disc replacement

Although currently a ‘hot topic’, Artificial Cervical Disc Replacement (ACDR) concept is not new

First forays into Spinal Disc Replacement surgery were mage in the 1950’s. Fernstrom used steel ball bearings (1966)(endoprosthesis) implanted into disc spaces

250 procedures were performed in the 1950 & 60’s. Results were poor with segmental hypermobility & balls subsiding through the vertebral endplates.

The Bristol Cummins Disc was invented in the 980’s. 22 were implanted. Complications included being too large, Screw loosening, Galvanic corrosion (titanium-stain steel), Howevere the was no wear even after 8 years.

The Prestige I Disc was invented in 1998 and in a Pilot study 15 patients received the disc at levels adjacent to a fusion only.

Design

Disc Replacements can be one piece or multiple pieces. The joint can be metal on metal or with a plastic spacer.
Cobalt Chrome is one of the toughest metals and is often used in the joint bearing surfaces whereas titanium is used adjacent to bone due to its more natural modulus more similar to bone.

Various methods can be used to fix the disc into bone such as screws and anchors

 

Potential advantages over Fusion Surgery

Cervical Fusion
95% successful fusion rates in nonsmokers and it is a Tried and tested procedure

Cervical Disc Replacement
Maintains segment motion and reduces adjacent disc disease.
Eliminates need for a bone graft
Faster recovery and reduced hospital LOS (debatable)
