Effect of posterior fusion surgery on idiopathic scoliosis in Iran

Background: Scoliosis is a sideways curve in the spine. Considering that postoperative complications are common among these patients, the aim of this study is to examine the postoperative complications of posterior fusion surgery with instrumentation among adult patients with idiopathic scoliosis. Methods: In this cross-sectional descriptive study, the postoperative complications were examined among 93 patients with idiopathic scoliosis who underwent posterior fusion surgery with instrumentation. The convenience sampling was used by referring to the files of these patients. The patients were classified into four groups according to the type of scoliosis deformity (long C-shaped, thoracic, thoracolumbar/lumbar, and double-curve) and the complications were compared together. Results: Postoperative respiratory problems were significantly different between the four groups of scoliosis deformity (P = 0.009); 35 cases of postoperative complications occurred and 20 of them were related to postoperative pulmonary complications. Conclusion: Postoperative complications are common among patients with idiopathic scoliosis who underwent posterior fusion surgery with instrumentation; in addition, pulmonary complications are the most common postoperative complication among these patients
