Abstract: Objective To construct a three-dimensional (3D) lumbar spine model to allow real-time complicated interactions in virtual lumbar surgery based on virtual reality technique. Methods The data of high-resolution CT slices were segmented and the contours were extracted. Surface rendering technique was adopted to construct of the lumbar spine model on the basis of serial contours, and the model was optimized according to the need of real-time interaction. Results The lumbar spine model with fewer polygons was characterized by high resolution and smoothness. After being loaded in the virtual surgery system, the model accurately displayed the anatomy of lumbar spine and allowed real-time interaction during the virtual surgery. Conclusion The 3D lumbar spine model constructed based on the CT slices is applicable for complicated interactions in virtual lumbar surgery.
