Abstract
Objective: To report the clinical and radiological outcomes after corrective osteotomy in ankylosing spondylitis patients. Subject and method: We prospectively analyzed 69 ankylosing spondylitis patients who underwent corrective osteotomy between 2010 and 2022. The clinical outcomes were assessed by the Oswestry Disability Index (ODI) scores and Scoliosis Research Society (SRS-22) index. The radiologic results were evalutated by radiologic measurements in standing lateral radiographs before and 3 months after surgery. Results: A total of 91 corrective osteotomies were performed in 69 patients with a mean follow-up of 30.1 months (range, 3 to 68 months). The mean correction angles were 24 0 ± 200 (range, -140 to 710). The thoracolumbar type was the most common. There were significant improvements in both the ODI score and SRS-22 (p<0.05). The mean ODI preoperative score was 50 ± 15%, (range, 31.7% to 88.3%) and postoperative ODI was 22.5 ± 6% (range, 16.7% to 46.6%). The mean SRS-22 score increased significantly from 9.2 ± 1.4 preoperative to 22.8 ± 1.7 at the 3 month postoperative moment. There were 28 surgery-related complications in 12 patients (17.3%). Conclusion: Corrective osteotomy is an effective method for treating a fixed kyphotic deformity occurring in ankylosing spondylitis, resulting in satisfactory outcomes with acceptable complications.
