SURGICAL TREATMENT OF CERVICAL SPINE FRACTURES IN PATIENTS WITH ANKYLOSING SPONDYLITIS

Abstract

Objective. To analyze the results of surgery for cervicothoracic deformity fractures in patients with ankylosing spondylitis. Material and Methods. Retrospective review of treatment for fractures of cervicothoracic deformity in 6 patients with ankylosing spondylitis was performed. All patients had transdiscal fractures caused by low-energy trauma, most frequently at C5–C6 and C6–C7 levels. Each patient had at least one comorbidity. The spinal cord was injured in 100 % of cases. Results. Postoperative complications were registered in all patients. Analysis of postoperative x-rays showed that spinal deformity was corrected in most cases, and the stable fixation was achieved at the operated level of the spine. Three patients who had underwent anterior fixation showed the regression of neurological symptoms. Patients classified as Frankel A died of cardiopulmonary insufficiency at 2–7 days after surgery without any signs of neurological symptom regression. Autopsy revealed severe spinal cord injury. Mortality rate was 50 %. Conclusion. Surgical treatment of cervical spine fractures providing a stable fixation reduces the risk of complications and allows for early activation of patients with ankylosing spondylitis.
