Surgical correction of thoracolumbar and lumbar scoliosis: efficacy and morbidity

AimTo investigate anterior instrumented corrective fusion for thoracolumbar or lumbar scoliosis.MethodsA retrospective review of medical records and radiographs of 38 consecutively managed patients who underwent anterior spine surgery for thoracolumbar curves by a single surgeon between 2001 and 2011. The cohort consisted of 28 female and 10 male patients with idiopathic scoliosis as the commonest aetiology. Data collated and analysed included patient demographics, surgical factors, post-operative management and complications. In addition, radiographic analysis was performed on pre-operative and follow-up x-rays.ResultsThoracolumbar/lumbar curves were corrected from 70 to 27 degrees. The thoracic compensatory curve spontaneously corrected from 34 to 19 degrees. Sagittal imbalance of greater than 4 centimeters was found in 40 percent of patients preoperatively and in 16 percent post operatively (85 percent negative sagittal imbalance, 15 percent positive sagittal imbalance).
