Some studies have shown that MC are strongly associated with low back pain (LBP) compared to disc degeneration alone. However, the long-term consequences in terms of Patient- Reported Outcomes (PROs) have not been reported. This study evalu- ated if MC is associated with long-term disability and pain. Purpose / Aim of Study: To evaluate is patients with Modic changes (MC) have worse long-term outcomes compared to patients without. Materials and Methods: In 2002, 207 patients with chronic low back pain were enrolled in an RCT comparing cognitive training with physical therapy. Inclusion criteria were age 18-60, almost daily LBP of ≥ 4 for more than 4 months in the past year. In 2017, these patients were then asked to complete the same PROs collected at baseline: back and leg pain (0-10), Roland-Morris Disability Questionnaire (RMDQ) and Inflammatory pain pattern (IPP). Patients were then stratified based on the presence or absence of MC on their initial low-Tesla MRI. Findings / Results: Of the 204 cases with MRIs in 2002, 82 (40%) had MC in a least one lumbar segment. In 2017, 167 cases (82%) were available for fol- low-up including 65 (39%) with MC. There were no differences in demograph- ics, smoking status, back-or leg-pain or IPP scores at baseline and at 13-year follow-up between patients with and without MC. RMDQ was similar in both groups at baseline but worse in patients without MC at follow-up. Conclusions: The current study showed that patients without MC who had pain and were referred to a back clinic have the same clinical presentation as patients with MC. However, patients with MC were found to have better long- term outcomes compared to patients without. 134.
