Abstract

Objective

The purpose of this study was to establish an anatomical foundation for minimally invasive lumbar spine surgery in adolescents by assessing the 3D anatomical parameters of the lumbar vertebrae in the age group of 12–21 years.

Methods

We collected CT data from 90 adolescents and performed 3D reconstructions using Mimics 16.0 software. The dimensions assessed included the height and sagittal diameter of the intervertebral foramen, as well as the length and widths of the transverse and spinous processes.

Results

The intervertebral foramen height exhibited variation corresponding to the vertebral level, being smallest at L5/S1 and largest at L3/4. The sagittal diameter of the intervertebral foramen increased with age, reaching a minimum at L1/2 and a maximum at L4/5. Significant gender differences were observed in the 12–14 age group, with females exhibiting larger measurements than males. The length and width of the transverse processes were maximal at L3 and L5, respectively. The spinous process length was greatest at L3 and smallest at L5, with notable gender differences present in the 12–14 and 19–21 age groups.

Conclusion

The study reveals that gender and age are significant factors influencing the anatomy of the adolescent lumbar spine, which is essential for the development of minimally invasive surgical techniques. Our findings contribute valuable insights for the design and surgical planning of spinal devices tailored to adolescents.
三维数字解剖测量在 12-21 岁青少年腰椎椎间孔微创手术中的临床应用。
研究目的本研究旨在通过评估 12-21 岁年龄组腰椎的三维解剖参数,为青少年微创腰椎手术奠定解剖学基础:我们收集了 90 名青少年的 CT 数据,并使用 Mimics 16.0 软件进行了三维重建。评估的尺寸包括椎间孔的高度和矢状直径,以及横突和棘突的长度和宽度:椎间孔高度随椎体水平而变化,L5/S1最小,L3/4最大。椎间孔的矢状直径随着年龄的增长而增加,在 L1/2 达到最小值,在 L4/5 达到最大值。在 12-14 岁年龄组中观察到明显的性别差异,女性的测量值大于男性。横突的长度和宽度分别在 L3 和 L5 达到最大值。棘突长度在 L3 最大,在 L5 最小,12-14 岁和 19-21 岁年龄组存在明显的性别差异:研究显示,性别和年龄是影响青少年腰椎解剖的重要因素,这对微创手术技术的发展至关重要。我们的研究结果为设计和手术规划适合青少年的脊柱装置提供了宝贵的见解。
