Computational modelling of spinal implants 449
materials and spine tissues depends strongly on several modelling assump-
tions, such as spine model geometry (Noailly et al ., 2007; Meijer et al .,
2011), tissue model assumptions (Noailly et al ., 2011; Kim et al ., 2011a),
and load boundary conditions (Noailly et al ., 2012). As such, most device
assessments must be performed by comparative analyses of untreated and
treated models, and interpretation of the computed results must take into
account the different model assumptions as well as the possible impact of
these assumptions on the calculations.
