This case highlights a rare complication of severe kyphosis surgery in ankylosing spondylitis (AS) with ossification of spinal ligaments. Early recognition and preparedness for thoracic myelopathy are crucial for better patient outcomes.
Area of Science:
- Spine surgery
- Orthopedics
- Neurology
Background:
- Severe thoracolumbar kyphosis in ankylosing spondylitis (AS) poses complex surgical challenges.
- Concurrent ossification of the posterior longitudinal ligament (OPLL) and yellow ligament (OYL) can complicate spinal procedures.
- High pelvic incidence-lumbar lordosis (PI-LL) mismatch necessitates corrective osteotomies.
