研究设计：对青少年脊柱侧凸患者的脊柱立体X线片进行横断面研究，以测量其生长情况。目的：确定7.5-20岁年龄范围内，椎体和椎间盘对T5和L5之间脊柱长度增加的相对贡献。背景资料概要：脊柱畸形的进展（脊柱侧弯）与骨骼生长有关，但青少年生长期间椎骨和椎间盘的不对称生长和重塑的相对作用尚不清楚。方法。现有数据库包含188名患有特发性脊柱侧弯的青少年的406项脊柱立体放射学研究，年龄在7.5 - 20岁之间，用于测量椎体和椎间盘的高度，以及两者的总和（脊柱长度）.结果.在这个年龄范围内，观察到脊柱长度从约250 mm增加到350 mm。脊柱生长与10岁以后椎体高度的增加相关，椎间盘高度的增加很小（如果有的话）。脊椎和椎间盘高度的贡献估计为每年约17和8毫米，分别在7.5岁，但椎间盘高度增长估计有效零后，年龄12 years.Conclusion.Spinal年龄在10和20岁之间的脊柱侧凸患者的生长几乎完全发生在椎骨的高度增加，而不是椎间盘。
Study Design.A cross-sectional study of spinal stereoradiographs of adolescents with scoliosis to measure growth.Objective.To determine the relative contributions of the vertebral bodies and intervertebral discs to the increase in spinal length between T5 and L5, over the age range of 7.5–20 years.Summary of Background Data.The progression of spinal deformity (scoliosis) is associated with skeletal growth, but the relative roles of asymmetrical growth and remodeling of the vertebrae and discs during adolescent growth are unclear.Methods.An existing database of 406 spinal stereoradiographic studies of 188 adolescents with idiopathic scoliosis, aged between 7.5 and 20 years, was used to measure the heights of vertebral bodies and intervertebral discs, and the summation of both (spinal length).Results.Spinal length was observed to increase from about 250 to 350 mm over this range of ages. Spinal growth was associated with an increase in vertebral height after age 10 years, with minimal if any increase in disc height. The contribution of vertebral and discal height was estimated to be about 17 and 8 mm per year, respectively, at age 7.5 years, but discal height growth was estimated to be effectively zero after age 12 years.Conclusion.Spinal growth of patients with scoliosis aged between 10 and 20 years occurs almost exclusively by height increases in the vertebrae, not the discs.
