ABSTRACT

BACKGROUND:

Orthopedic osteotomy at the apex of kyphosis is best for treatment of ankylosing spondylitis from a biomechanical aspect, but there is a high risk for intraoperative spinal cord injury.

OBJECTIVE:

To explore the clinical efficacy of vertebral plate osteotomy+vertebra osteotomy+long-segment pedicle screw fixation in the treatment of ankylosing spondylitis with kyphotic deformity.

METHODS:

Thirty-six patients with ankylosing spondylitis were subjected to pedicle subtraction osteotomy and Smith-Peterson osteotomy, and then fol owed up for 3 months to 2 years. RESULTS AND

CONCLUSION:

After implantation, sagittal imbalance did not occur in 36 patients, and the improvement rate of sagittal imbalance was 64%. The improvement rates of thoracolumbar kyphosis and chin-brow vertical angle were 60%and 98%, respectively. The pain relief rate was 64%, and the Oswestry Disability Index was 95%. There were no pul ed nails, broken nails and broken robs after implantation. These findings indicate that the combination of selective osteotomy technique and long-segment internal fixation can achieve stable fixation effects, prevent sagittal imbalance, and avoid the occurrence of pul ing nails, breaking nails and breaking robs caused by osteoporosis.
