Does hip structural damage affect the lower extremity compensations in ankylosing spondylitis patients with thoracolumbar kyphosis before and after pedicle subtraction osteotomy?
To investigate the effect of hip structural damage on compensatory mechanisms in the pelvis and lower extremities of AS patients with thoracolumbar kyphosis, and to identify a useful spinopelvic parameter for assessing these compensations before and after PSO.
Key Findings:
57 patients included: 26 in mild hip involvement (MHI) and 31 in severe hip involvement (SHI) groups.
No significant differences in demographics or fusion levels between MHI and SHI groups.
Radiographic parameters showed no statistical difference between MHI and SHI groups pre-surgery.
Interpretation:
Understanding hip structural damage's impact is crucial for assessing compensatory mechanisms in AS patients, potentially influencing surgical outcomes.
Limitations:
Single-center study may limit generalizability.
Retrospective design may introduce selection bias, affecting the reliability of findings.
Conclusion:
The study underscores the importance of evaluating hip involvement in AS patients with thoracolumbar kyphosis to enhance understanding of compensatory mechanisms and improve surgical planning.
