AB  - STUDY DESIGN: Retrospective study. PURPOSE: To calculate the minimum clinically 
      important difference (MCID) for total and individual domains of the Oswestry 
      Disability Index (ODI) and assess score distribution and changes over time in 
      surgically treated adult spinal deformity (ASD) patients. OVERVIEW OF LITERATURE: 
      Despite the common use of ODI for assessing ASD, there are no robust studies 
      defining MCID values for this index. METHODS: This study included 240 consecutive 
      ASD patients with a minimum of 2 years of follow-up. We calculated MCID values 
      for total and individual ODI domains using all or part of the Scoliosis Research 
      Society-22R questionnaire as anchors. Using current MCID values, we measured the 
      acquisition rates in patients who acquired MCID at follow-up in both total and 
      individual ODI domains. Differences in pathology, age, and locations of the upper 
      and lower instrumented vertebrae were analyzed. RESULTS: MCID of the total ODI 
      score was 11%, with an area under the curve of 0.737. Each domain ranged from 0 
      to 2, with 1 being the most common value. In the pain and standing domains, >60% 
      of the patients acquired MCID, although acquisition rates of the personal care, 
      lifting, sleep, and sexual activity domains were relatively low (20%-35%). 
      Patients with MCID had more radiographic improvement in lumbar lordosis, sagittal 
      vertical axis, and T1 pelvic angle than those without MCID (p<0.05). CONCLUSIONS: 
      To our knowledge, this is the first study to describe MCID of ODI (11%) after ASD 
      surgery. In the pain and standing domains, most patients acquired MCID although 
      the rates of acquisition of MCID in the personal care, lifting, sleep, and sexual 
      activity domains were low. Spine surgeons should counsel their patients regarding 
      the benefits and setbacks of ASD surgery.
