STUDY DESIGN Finite element study. OBJECTIVE To investigate intradiscal pressure, shear strain between anulus and adjacent endplates, and fiber strain in the anulus under pure and combined moments. SUMMARY OF BACKGROUND DATA Concerning anulus failures such as fissures and disc prolapses, the mechanical response of the intervertebral disc during combined load situations is still not well understood. METHODS A 3-dimensional, nonlinear finite element model of a lumbar spinal segment L4-L5… CONTINUE READING
