The amount of immediate correction necessary to nullify the bending moment ranged between 19% and 61% with average 48% (flexible spine model) and 27% (stiff spine model).
CONCLUSION: the finite element model of artificial disc replacement can be established by CT scanning, digital processor and computer aided design, and used for further study on spinal biomechanics.
