目的探讨青少年特发性脊柱侧凸(AIS)患者冠状畸形角比(C-DAR)与支撑矫正(IBC)的关系及其对长期支撑结局的预测作用。
在这项回顾性多中心研究中,病人的性别,年龄,初级曲线Cobb角(在支具治疗开始时,最好的支架,脊柱融合术前,和最终随访),曲线模式,支具治疗的持续时间,撑杆类型,记录支撑开始时的C-DAR。C-DAR值分类为<5、5≤至≤6和>6。IBC值分类为≥50%,40%≤到≤49%,和<40%。我们在最终随访时根据Cobb角将患者分为成功和失败两组。
共纳入164名患者(25名男孩和119名女孩)。其中60.4%的支持成功。C-DAR与支撑结果之间存在显著关联(p<0.0001)。63.9%C-DAR<5的患者IBC≥50%。然而,当C-DAR为5≤≤6且>6时,29.2%和16.9%的患者IBC≥50%,分别。对于IBC≥50%的患者,支撑成功率为89.2%。logistic回归分析结果显示,支撑治疗结果的最强预测因子是C-DAR,赔率比为2.11。
C-DAR可用作AIS中支具治疗的长期结果的预测因子。

To investigate the relationship between coronal deformity angular ratio (C-DAR) and in-brace correction (IBC) and their role in predicting the long-term bracing outcome in adolescents with idiopathic scoliosis (AIS).
In this retrospective multicenter study, the patient\'s sex, age, primary curve Cobb angle (at initiation of brace treatment, best in-brace, before spinal fusion, and final follow-up), curve pattern, duration of brace treatment, brace type, and C-DAR at initiation of bracing were recorded. The C-DAR values were classified as < 5, 5 ≤ to ≤ 6, and > 6. The IBC values were classified as ≥ 50%, 40% ≤ to ≤ 49%, and < 40%. We classified the patients into two groups of success and failure according to the Cobb angle at the final follow-up.
A total of 164 patients (25 boys and 119 girls) were included. Bracing was successful in 60.4% of them. There was a significant association between C-DAR and bracing outcome (p < 0.0001). 63.9% of the patients with C-DAR < 5 had an IBC ≥ 50%. However, when C-DAR was 5 ≤ to ≤ 6 and > 6, 29.2% and 16.9% of the patients had an IBC of ≥ 50%, respectively. For patients with IBC ≥ 50%, the success rate of bracing was 89.2%. Results of logistic regression analysis revealed that the strongest predictor for brace treatment outcome was the C-DAR, with an odds ratio of 2.11.
C-DAR may be used as a predictive factor for the long-term outcome of brace treatment in AIS.
