An improved and detailed 3D FE model of human cervical spine model was created using digitized geometric measurement tool. The vertebral bodies of the model were fused at three locations. The unfused and the fused models were physiologically loaded and the changes in stresses in intervertebral discs were compared. A moment of 1.5 Nm was used in combination with a 50 N compressive preload. The results showed that the lower cervical spine fusion induces the most stress changes in the neighboring discs.
