Summary
Re-stooping after corrective osteotomy in ankylosing spondylitis (AS) is linked to changes in the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS). Managing mSASSS may help prevent posture recurrence post-surgery.
Area of Science:
- Orthopedic Surgery
- Spine Surgery
- Rheumatology
Background:
- Ankylosing spondylitis (AS) patients often undergo corrective osteotomy for posture.
- Post-surgical re-stooping is a concern, but factors influencing it are unstudied.
- This study investigates predictors of re-stooping after AS corrective osteotomy.
Purpose of the Study:
- To identify factors contributing to re-stooping after thoracolumbar corrective osteotomy in AS patients.
- To analyze demographic and radiological parameters associated with posture recurrence.
Main Methods:
- Retrospective analysis of 50 AS patients undergoing thoracolumbar corrective osteotomy.
- Patients classified into non-re-stooping (N) and re-stooping (R) groups based on correction loss.
- Radiological parameters including mSASSS, sagittal vertical axis, and spinal angles were assessed.
Main Results:
- A significant difference in mSASSS change was observed between the N group (2.87 ± 3.08) and R group (9.20 ± 5.44).
- Multivariate analysis revealed a significant correlation between the ratio of correction loss and the change in mSASSS from pre-surgery to final follow-up.
Conclusions:
- Thoracolumbar corrective osteotomy offers high patient satisfaction but re-stooping can occur.
- Changes in mSASSS are a key factor associated with re-stooping.
- Postoperative management including rehabilitation and medication may mitigate AS progression.
