Objective To determine abnormal MRI fi ndings in adults hospitalized with acute severe axial LBP. Method Sixty patients with back pain were divided into 3 groups consisting of 1) 23 adults with acute axial severe LBP who could not sit up or stand up for several days, but had not experienced previous back-related diseases or trauma (group A), 2) 19 adults who had been involved in a minor traffi c accident, and had mild symptoms but not limited mobility (group B), and 3) 18 adults with LBP with radicular pain (group C)., Various MRI fi ndings were assessed among the above 3 groups and compared as follows: disc herniation (protrusion, extrusion), lumbar disc degeneration (LDD), annular tear, high intensity zone (HIZ), and endplate changes. Results Th e MRI fi ndings of A group were as follows: disc herniation (87%), LDD (100%), annular tear (100%),HIZ (61%), and end plate changes (4.4%). Th e fi ndings of disc herniation, annular tear, HIZ, and LDD were more prevalent in A group than in B group (p<0.01). HIZ fi ndings were more prevalent in A group than in group B or group C (p<0.05). Conclusion Patients with acute severe axial LBP were more likely to have disc herniation, LDD, annular tear, HIZ. Among LBP groups, there was a signifi cant association of HIZ on MRI with acute severe axial LBP.
