This work presents a new methodology for implementation of facet joints in the lumbar spine model developed by De Zee et al. (2007: J Biomech. 40, 1219-1227). It enables the facet joint forces to become part of a redundant system of equilibrium equations for the entire system including the muscles. This redundant system is subsequently solved uniquely thereby making it possible to analyze the effect of whole body movements and loads on facet joint loading for the whole lumbar spine together with its muscles.
