The term Keyhole Disc Replacement is in itself misleading because the procedure replaces the central portion of the disc (Nucleus Pulposus) rather than the whole disc including the Disc Wall (Annulus).

The author considers that the problems surrounding Total Disc Replacement center on :

The replication of an individual’s disc. The Replacements are available in a small number of sizes which fail to accurately match the disc. Patients may be tall/short, fat or thin. Patients may be asymmetrical, scoliotic and may have varieties of postures. All of these features make for a variation in the natural disc. Then the size (footprint), shape and height of all the discs (par example L3/4, L4/5, and L5/S1 discs) are all different. Manmade Replacements simply do not replicate the disc accurately.

Their failure to replicate the complex movement patterns of a disc. Discs do not simply bend in one direction. The presence of the posterior facet joints dictates a complex ellipsoidal pattern of movements upon the disc. The orientation of these joints varies significantly from person to person. The Total Disc Replacement fails to replicate these movements.
