Risk Factors for Scoliosis Progression in Children with Idiopathic Short Stature on Growth Hormone Therapy

Objective : To analyze the clinical characteristics of scoliosis in children with idiopathic short stature after growth hormone treatment, and to explore the influence of growth hormone treatment on the progression of scoliosis and the risk factors for the progression of scoliosis. Methods : A retrospective study of children with scoliosis treated with growth hormone between January 2021 and June 2024 was conducted, analyzing the clinical characteristics of scoliosis and comparing the progression rate of scoliosis between the exposure group and the control group. Independent risk factors for exacerbation of scoliosis were determined by univariate and multifactorial logistic regression analysis. Results : In this study, the median Cobb Angle at the initial diagnosis of scoliosis in all children was 11°. Scoliosis mostly occurred at the thoracolumbar junction, and its apical vertebrae were distributed in thoracic 10- lumbar 1 (64.17%). The progression rate of scoliosis in the exposure group was significantly higher than that in the control group, and the risk ratiowas 4.26. Univariate and multivariate logistic regression analyses showed that continued growth hormone treatment and the initial Cobb Angle were independent risk factors for scoliosis progression. Conclusion : 1. Scoliosis developing in children with idiopathic short stature (ISS) receiving growth hormone (GH) therapy predominantly manifests as mild curvature. 2. If scoliosis develops during GH therapy, continued treatment may increase the risk of scoliosis progression. 3. Patients with smaller initial Cobb Angles are at higher risk of progression, necessitating closer clinical monitoring for this subgroup.
