Study DesignA retrospective observational study.ObjectiveTo introduce a novel hybrid technique using segmentation correction (SC) and to compare it with traditional correction (TC) in treating dystrophic scoliosis secondary to neurofibromatosis type 1 (NF1-S) lacking pedicles in the apical area.MethodsWe reviewed the NF1-S cases lacking pedicles diagnosed in our hospital between January 2015 and December 2019. Patients were divided into the SC and TC groups and were followed up for at least 2 years. The degree of deformities, correction rate, and vertebral rotatory subluxation (RS) were assessed before the operation, post-traction, post operation, and during follow-up visits.ResultsA total of 27 patients were included in the SC group and 21 in the TC group. There was no significant difference in the 2 groups before the surgery regarding age, height, weight, degree of deformities, and spinal flexibility. The correction rate of patients in the SC group was higher (57.7% ± 17.3% vs. 40.9% ± 19.0%, P = 0.002) than in the TC group. During the 2-year follow-up, the loss of Cobb angles of the SC group in both coronal and sagittal planes were lower than those of the TC group (coronal plane, 1.2° ± 1.1° vs. 2.0° ± 1.4°, P = 0.039; sagittal plane, 0.9° ± 0.5° vs. 1.7° ± 1.0°, P = 0.002).ConclusionsThe SC technique showed better deformity correction than TC, suggesting that SC may be an alternative method for treating NF1-S patients lacking pedicles in the apical area.Copyright © 2022 Elsevier Inc.
