摘要

基于5例AIS手术病例的临床资料，建立有限元模型，模拟患者体位和脊柱内固定。模拟了不同的患者体位和器械配置，并分析了相关的校正和螺钉拔出力。患者俯卧位导致Cobb角降低超过5°。胸垫垂直、尾侧和头侧移位对胸后凸有显著影响。骨盆旋转通过下肢伸展/屈曲对腰椎前凸有显著影响。经过验证的FEM可以模拟患者的体位和脊柱内固定。患者体位配置对畸形矫正和螺钉拔出力有显著影响。

Biomechanical modeling and assessment of patient positioning to facilitate spinal deformity instrumentation.

Finite element models (FEM) were built based on clinical documentation of five AIS surgical cases to simulate patient positioning and spinal instrumentation. Various patient positioning and instrumentation configurations were simulated, and the associated corrections and screw pull-out forces were analyzed. Patient prone-positioning resulted in Cobb angle reduction of over 5°. Vertical, caudal, and cephalad displacement of thoracic cushions had significant impact on thoracic kyphosis. Pelvic rotation through lower-limb extension/flexion had significant effect on lumbar lordosis. The validated FEM enabled simulations of patient positioning and spinal instrumentation. Patient positioning configurations had significant effects on deformity correction and screw pull-out forces.

期刊介绍： The primary aims of Computer Methods in Biomechanics and Biomedical Engineering are to provide a means of communicating the advances being made in the areas of biomechanics and biomedical engineering and to stimulate interest in the continually emerging computer based technologies which are being applied in these multidisciplinary subjects. Computer Methods in Biomechanics and Biomedical Engineering will also provide a focus for the importance of integrating the disciplines of engineering with medical technology and clinical expertise. Such integration will have a major impact on health care in the future.
