Factors and predictive model associated with perioperative complications after long fusion in the treatment of adult non-degenerative scoliosis

Abstract Introduction Adult non-degenerative scoliosis accounts for 90% of spinal deformities in young adults. However, perioperative complications and related risk factors long posterior instrumentation fusion the treatment adult have not been adequately studied. Methods We evaluated clinical radiographical results from 146 patients with who underwent fusion. Preoperative data, intraoperative variables, radiographic parameters were collected to analyze complications. Potential independent by univariate analysis logistic regression analysis. Results One hundred forty-six included our study. There 23 21 (14.4%) patients, eight which cardiopulmonary complications, two infection, six neurological three gastrointestinal four incision-related complication. The development total change Cobb angle (odds ratio [OR] = 1.085, 95% CI 1.035 ~ 1.137, P 0.001) osteotomy (OR 3.565, 1.039 12.236, 0.043). factor minor is 1.092, 1.023 1.165, 0.008). major are 4.475, 1.960 20.861, 0.036) 1.106, 1.182, 0.003). Conclusions Our study indicate that after long-segment patients. Change an
