    ObjectiveThe objective of the study was to compare the efficacy of halo-gravity traction (HGT) with subsequent surgical treatment in adolescent and adult patients with severe scoliosis by evaluating the radiographic outcomes and clinical complications.MethodsWe performed a retrospective analysis of 51 patients with severe scoliosis who underwent a posterior spinal instrumented fusion with HGT during the perioperative period between March 2010 and June 2017. The patients were divided into 2 groups: adults (age >18 years) and adolescents (age 10-18 years). All patients were followed with full posteroanterior and lateral spine radiographs, bending films, neurological complications, and lung function tests for a minimum of 2 years. Deformity correction, pulmonary function testing, and clinical complications were compared between the 2 groups.ResultsWe identified 29 adults (8 males and 21 females, mean age = 23.7 ± 8.7 years) and 22 adolescents (10 males and 12 females, mean age = 13.0 ± 4.5 years). In the adult group, the mean Cobb angle of the main curve before HGT was 141.7 ± 18.2°, which improved to 126.4 ± 8.6° and 67.5 ± 10.2° after traction and operation, respectively. The kyphotic angle was corrected from 137.1 ± 15.6° before traction to 122.5 ± 11.3° after traction to 67.6 ± 13.8° after operation. The mean functional vital capacity% and forced expiratory volume in one second% were 43.1% and 37.5%, which improved to 46.7% and 41.7% after traction, respectively. In the adolescent group, the mean correction of the main curve improved from 139.3 ± 12.6° before traction to 112.1 ± 8.3° after traction to 59 ± 13.1° after surgical intervention. The kyphotic angle was corrected from 130.7 ± 9.4° before traction to 101.5 ± 12.2° after traction and then to 48.2 ± 10.1° after surgical intervention. Overall, patients in both groups showed significant improvement in their main scoliosis and kyphosis (P < 0.05), while the correction rate of the main curve and kyphosis was significantly higher in the adolescent group than that in the adult group (P < 0.05). The functional vital capacity% increased from 44.8% to 55.0% and the forced expiratory volume in one second% increased from 44.0% to 51.0% after using HGT. In terms of surgical outcomes, the incidence of postoperative neurological complications was 27.6% and 18.2% in the 2 groups, respectively.ConclusionsHGT is an effective and safe method to correct spinal deformities and improve lung function, especially in adolescent patients with severe scoliosis. In addition, it can potentially reduce the risk of neurological complications and the level of osteotomy in posterior spinal instrumented fusion surgery.Copyright © 2022 Elsevier Inc.
