high risk of falling, and assessment results can be used to facilitate community-based intervention.BACKGROUND Lumbar spinal fusion with rigid spinal fixators as one of the high risk factors related to adjacent-segment failure. The purpose of this study is to investigate how the material properties of spinal fixation rods influence the biomechanical behavior at the instrumented and adjacent levels through the use of the finite element method. METHODS Five finite element models were constructed in our study to simulate the
