Computational biomechanical models have the potential to broaden our understanding and to aid the work of many practicing medical professionals. However, these models are only reliable, thus applicable and valuable, insofar as they are able to replicate a specific portion of reality. Therefore, validation of computational models is indispensable. To ensure that our proposed 3D finite element head-neck model does bear meaningful resemblance to real cervical spines, we relied on all available relevant rotation-moment measurements. Previously proposed validation metrics were used to quantify model error and experimental uncertainties. These metrics may be adopted for a wide range of other applications as well. Our model was found to be adequate for the study of kinematical properties of the human cervical spine.
