Abstract
The aim of the present study was to identify risk factors for perioperative complications associated with spinal surgery for cervical, thoracic, and lumber spinal stenosis in a Japanese cohort. Patients with spinal stenosis who underwent spinal surgery between 2008 and 2012 were included. Neurological and/or surgical site complications within 30days of index surgery were retrospectively collected, and the rates of complications were calculated. Using univariate and multivariate logistic regression analyses, risk factors for complications were identified. A total of 364 patients underwent 407 spinal surgeries. Of the 407 surgeries performed, 236 were cervical, 28 were thoracic, and 143 were lumbar surgeries. Ossification of the ligamentum flavum was the most common diagnosis in patients with thoracic stenosis (85%), whereas spinal degenerative stenosis and disc herniation were the two most common diagnoses in patients with cervical and lumbar stenosis. Laminoplasty and laminectomy alone were the two most frequently performed procedures. The rate of complications was greater in patients with thoracic stenosis (36%) than in those with cervical (16%) or lumbar stenosis (13%, p=0.013). After a multivariate analysis, only thoracic st...Continue Reading
