To investigate the maturation of the peripheral nervous system by analyzing the cross-sectional area of the sciatic nerve during the first 2 years of life.
The sciatic nerve was examined by high-resolution ultrasound imaging in 52 children aged 0 days to 10 years, 45 of whom were younger than 2 years. The correlation between the cross-sectional area of the nerve and the age was statistically tested. A logarithmic regression analysis was performed to develop a logarithmic growth model of the cross-sectional area.
There is a highly significant correlation between the age and the cross-sectional area of the sciatic nerve. The growth rate can well be described by a logarithmic model.
Based on the literature on the maturation of the median nerve and nerve roots and the findings of the present study, we conclude that both the proximal and the distal parts of the nerves of the peripheral nervous system increase simultaneously.

通过分析出生后前 2 年期间坐骨神经的横截面积来研究周围神经系统的成熟度。
对 52 名年龄在 0 天至 10 岁的儿童进行了高分辨率超声成像检查，其中 45 名儿童年龄小于 2 岁。对神经横截面积与年龄之间的相关性进行了统计学检验。对数回归分析用于建立横截面积的对数生长模型。
坐骨神经的横截面积与年龄之间存在高度显著的相关性。生长率可以很好地用对数模型来描述。
基于正中神经和神经根成熟的文献以及本研究的结果，我们得出结论，周围神经系统的神经近端和远端同时增加。
