A mathematical model for the study of the mechanics of the human vertebral column.

摘要: Abstract The construction of a mathematical model for studies the mechan cal function human vertebral column is described. modeled as collection rigid bodies, and equilibrium or geometrical configurations are sought to satisfy constraints imposed so simulate action real spine. initial conducted with demonstrate geometry three-dimensional motions spine in flexion, extension, lateral bending, axial rotation. In each case, predicted deformations ligaments intervertebral discs anatomically reasonable. Agreement in-vivo other investigators obtained. It shown that not geometrically constrained have patterns motion, but can achieve many variety ways.
