A finite element model for predicting the biomechanical behaviour of the human lumbar spine

摘要

The aim of this study was to develop a biomechanically validated finite element model to predict the biomechanical behaviour of the human lumbar spine in compression. For validation of the finite element model, an in vitro study was performed: Twelve human lumbar cadaveric spinal segments (six Segments L2/3 and six segments L4/5) were loaded in axial compression using 600 N in the intact state and following surgical Treatment using two different internal stabilisation devices. Range of motion was measured and used to calculate stiffness.
