Motion preservation technology for the spine has specific design goals that differ dramatically from fixation technology. In order to accurately characterize motion preservation devices, new methods of biomechanical testing along with new metrics for comparison are needed. Devices designed to serve as an adjunct to fusion, i.e., spinal fixation instrumentation, have traditionally relied on arthrodesis to off load the implant over time as the fusion mass gains structural integrity. However, motion preservation devices are expected to function continuously for extended periods of time.
