Objective To study the methods for constructing a digitized three‐dimensional ( 3D ) model of a virtual lumbar region and its adjacent structures in order to assist anatomical study and virtual surgery. Methods Images of DSCF5375 ‐p1 to DSCF5745 ‐p1 were taken from the database of the digitized V irtual C hinese human of S outhern M edical U niversity in G uangzhou. This region encompasses the superior facet joint of L 4 to the inferior edge of the intervertebral body of L 5 . The regions of interest were interactively segmented from the images utilizing Adobe Photoshop software. The images were further processed using format conversion and segmentation. Finally, a 3D model of the L 4–5 region and its neighboring structures was reconstructed with the assistance of M imics 10.01 software. Results A digitized 3D model of this part of the virtual lumbar spine and its adjacent structures was reconstructed. This model allows all constructed structures to be displayed individually or jointly, moved or rotated arbitrarily, setting of different transparencies and convenient measurement of the diameters and angles of the reconstructed structures. The 3D model precisely displays the anatomical relationships between all structures and provides a reliable 3D model for a spinal endoscopic surgery simulation system. Conclusion Visualization of the digitized 3D reconstruction of the virtual lower lumbar region displays this region and its adjacent structures stereoscopically and in actuality, thus providing morphological data concerning anatomy, image diagnosis and virtual operations in this region.
