BACKGROUND: The aim of our study was to evaluate the incoming interrelations between chronic low back pain and biomechanical changes of the lumbar spine, using an MRI-compatible axial-loading device mimicking the standing position. MATERIALS AND METHODS: Fifty consecutive patients (28 males and 22 females), with both chronic low pack pain and recurrent painful blockages, were selected and studied using a 1.5 T Gyroscan Intera Philips MRI unit (Philips, Best, Holland) and a dedicated axial loading apparatus (MIKAI manufacturing, Genoa, Italy). RESULTS: After loading, no significant modifications occurred in ten patients (20%), a spinal stenosis was seen in 18 patients (45%), an increase in the discal protrusions or hernias was detected in 8 patients (20%) and a significant accentuation of the spondylolisthesis was observed in 6 patients (15%). CONCLUSION: Axial loading MRI provides valuable information for specific non-invasive or operative management of low back pain.
