The present study established the locations and loci of the IARs at vertebral levels T11-T12 and T12-L1 in sagittal, frontal, and transverse planes using the FE method. The IAR locations and loci were found to vary and the loci of the IARs were observed to move along different tracks with rotation in three anatomical planes.
