abstract

As motion preservation implants begin to replace fusion devices for lumbar degenerative disc disease, preclinical mechanical testing of these devices is critical to predicting their in vivo safety and efficacy. ISO and ASTM standards committees have tried for years to develop a universal test standard for all lumbar disc implants. The eDisc, an elastomeric/titanium disc replacement, is substantially different in its mechanical performance than the Synthes ProDisc or J&J Charite disc. These discs rely on ball and socket motion about a fixed or moving center or rotation to provide motion restoration in 3 to 5 axes. In contrast, the eDisc has viscoelastic motion in 3 translation and 3 rotational directions, just as in the natural human disc.
