Cross-sectional descriptive study.
To describe the normal rate pattern of thoracic spine growth in children without any spinal deformity.
The knowledge of thoracic spine growth and height is important for growing spine treatment and the decision of final fusion. Currently, pediatric spinal deformity is approached as early onset and late onset with an understanding of the fast growth during the first 5 years of life. The growth data that support this classification is often cited but has not been reconfirmed with follow-up studies.
Sagittal computed tomography (CT) reformations of thoracic vertebrae were examined in children without spinal deformity. The sagittal CT cut at the widest canal diameter was identified and the measurements were performed on this image. The length of the thoracic spine was measured from the posterosuperior corner of T1 to the posteroinferior corner of the T12.
One hundred forty-four thoracic CT scans satisfied the inclusion criteria. The analysis of the data identified two break points in the growth velocity; one at the end of the 4th year of life and the other at the beginning of the 12th year. Specifically, growth rate between 1 and 4 years was 1.71 cm/yr, between 4 and 8 years was 0.55 cm/yr, between 8 and 10 was 0.74 cm/yr, between 10 and 12 was 0.69 cm/yr, and between 12 and 16 was 1.61 cm/yr.
The results show that in growing children the thoracic spine demonstrates two major growth spurts. The initial growth spurt is between the birth to the end of the fourth year of life and the second is between the 12 and 16 years of age. Between 4 and 12 years there is a steady but slower increase in thoracic height. The findings show that the fastest growth velocity may be limited to a younger age group than previously believed. This data will help guide growth friendly management strategies.
横断面描述性研究。
描述无脊柱畸形儿童胸椎生长的正常速率模式。
胸椎生长和身高的知识对于生长中的脊柱治疗及最终融合的决策很重要。目前，小儿脊柱畸形分为早发型和晚发型，这基于对生命最初5年快速生长的认识。支持这种分类的生长数据常被引用，但尚未经后续研究再次证实。
对无脊柱畸形儿童的胸椎矢状面计算机断层扫描（CT）重建图像进行检查。确定椎管直径最宽处的矢状面CT切片，并在此图像上进行测量。胸椎长度从T1后上角测量至T12后下角。
144例胸椎CT扫描符合纳入标准。数据分析确定生长速度有两个转折点，一个在4岁末，另一个在12岁初。具体而言，1至4岁的生长速度为1.71厘米/年，4至8岁为0.55厘米/年，8至10岁为0.74厘米/年，10至12岁为0.69厘米/年，12至16岁为1.61厘米/年。
结果表明，在生长中的儿童中，胸椎有两个主要生长高峰。最初的生长高峰在出生至4岁末，第二个在12至16岁。4至12岁之间，胸椎高度稳步但缓慢增加。研究结果表明，最快生长速度可能局限于比先前认为更年轻的年龄组。这些数据将有助于指导有利于生长的管理策略。
