| Abstract: | Objective To create a 3D finite element model on images of L4 - L5 spondylolisthesis for experimental study of biomechanics. Methods A volunteer with lumbar spondylolisthesis was treated as the subject, and the sectional images of L4 - L6 spondylolisthesis were obtained through Spiral CT scanning. After the images were handled by computer program Adobe Photoshop 5.0. The L4 - L5 spondylolisthesis images were divided into different units and nodes to create a 3D model. Results We created a 3D model of L4 - L5 spondylolisthesis including 662 units and 1162 nodes. Conclusion Finite element model of L4 - L5 spondylolisthesis can be created by means of CT scanning and computer aided design. |
