Abstract:

BACKGROUND: The biomechanical study of lumbar disk bulging is significant.
OBJECTIVE: To investigate the digital model and three-dimensional visualization of lumbar disk bulging segment.
METHODS: Bone structure and various soft tissues of the lumbar spine were reconstructed by Mimics software based on 16-slice spiral CT continuous two-dimensional 114 images of L3-4 segments. The models were verified by introduced finite element analysis software.
RESULTS AND CONCLUSION: The established three-dimensional digital model of lumbar disk bulding segment included two vertebral bodies, endplate, annulus fibrosus, nucleus pulposus and six types of ligaments. The digital model could be used for research of three-dimensional measurement, reduction, surgical simulation, output as computer aided design, rapid prototyping, and finite element analysis based on its natural appearance and strong entity. It is indicated that thin-layer CT and Mimics software ensure more accurate and rapid establishment of digital model in order to facilitate further research.
