Cross-sectional and longitudinal retrospective study.
To measure thoracic dimensions and volume during growth in early-onset idiopathic scoliosis (EOIS) patients and to compare them to a population of asymptomatic adults and to the previous literature.
Data on trunk growth for scoliotic children between 6 and 14 years of age is sparse in the literature.
Thirty-six patients (29 girls and 7 boys, between 3 and 14 years old, average Cobb angle 33°±15°) were included, all with a minimum two-year follow-up. Sixty-one asymptomatic girls and 54 asymptomatic adults were included as control groups. All subjects underwent biplanar radiography and 3D reconstruction of the spine, pelvis, and rib cage. EOIS patients repeated their radiologic examination every six months. Cobb angle, rib cage volume, anteroposterior and transverse diameters, thoracic index, thoracic perimeter, pelvic incidence, and T1-T12 and T1-S1 distance were calculated. Reproducibility of measurement was assessed.
Measurement reliability in such young patients was comparable to previous studies in adolescents and adults. Geometrical parameters of EOIS patients increased linearly with age. For instance, rib cage volume in girls with EOIS increased from 2200 cm at six to seven years of age to 4100 cm at 13-14 years (65% of adult values, 294 cm/y). Comparison with asymptomatic girls showed that EOIS could affect growth spurt. Longitudinal analysis on a cohort of six girls who had a follow-up of six years confirmed the cross-sectional data.
In this longitudinal and cross-sectional study, trunk growth between 3 and 14 years of age was characterized, for the first time, with biplanar radiography and 3D reconstruction. The results can be useful to estimate patient growth and thus have potential application in the surgical planning of EOIS patients.
Level II, retrospective study.
横断面和纵向回顾性研究。
测量早发性特发性脊柱侧凸（EOIS）患者生长过程中的胸廓尺寸和容积，并将其与无症状成年人及既往文献进行比较。
文献中关于6至14岁脊柱侧凸儿童躯干生长的数据较少。
纳入36例患者（29例女孩和7例男孩，年龄在3至14岁之间，平均Cobb角33°±15°），均至少随访两年。纳入61例无症状女孩和54例无症状成年人作为对照组。所有受试者均接受脊柱、骨盆和胸廓的双平面X线摄影及三维重建。EOIS患者每六个月重复进行影像学检查。计算Cobb角、胸廓容积、前后径和横径、胸廓指数、胸廓周长、骨盆倾斜度以及T1-T12和T1-S1距离。评估测量的可重复性。
此类年轻患者的测量可靠性与既往青少年和成年人研究相当。EOIS患者的几何参数随年龄呈线性增加。例如，EOIS女孩的胸廓容积从6至7岁时的2200立方厘米增加到13 - 14岁时的4100立方厘米（为成人值的65%，每年增长294立方厘米）。与无症状女孩的比较表明，EOIS可能影响生长突增。对一组随访六年的六名女孩进行的纵向分析证实了横断面数据。
在这项纵向和横断面研究中，首次通过双平面X线摄影和三维重建对3至14岁的躯干生长进行了表征。这些结果有助于估计患者的生长情况，因此在EOIS患者的手术规划中具有潜在应用价值。
