腰椎间盘膨出节段数字模型及三维可视化
Digital model and three-dimensional visualization of lumbar disk bulging segment
摘要
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 on16-slice spiral CT continuous two-dimensional 114 images of L3-4 segments. The models were verified by introduced finiteelement analysis software.RESULTS AND CONCLUSION: The established three-dimensional digital model of lumbar disk bulding segment included twovertebral bodies, endplate, annulus fibrosus, nucleus pulposus and six types of ligaments. The digital model could be used forresearch 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 Mimicssoftware ensure more accurate and rapid establishment of digital model in order to facilitate further research.关键词
