Abstract

Aim: The aim of the study was to establish reference values for the cross-sectional area of the tibial nerve on high-resolution ultrasonography and to investigate the relationship between the cross-sectional area of the tibial nerve and subject's age, gender, height (in cm), weight (in kg) and body mass index.

Methods: Two hundred subjects of either gender and over 18 years of age with no history of peripheral neuropathy or trauma to the lower limb were evaluated with high-resolution ultrasonography. Mean cross-sectional areas of tibial nerves were measured at two different levels in both lower limbs, first at 1 cm below the bifurcation of the sciatic nerve into tibial and common peroneal nerves (level I) and the second at 1 cm superior and posterior to the medial malleolus (level II).

Results: The mean cross-sectional area measured at level I (0.196 + 0.014 cm2) was larger than the one measured at level II (0.111 ± 0.011 cm2). A positive correlation was found between the mean cross-sectional area and height, weight, and body mass index (p <0.05). Women had smaller cross-sectional areas of the tibial nerves than men at both sites. In addition, no significant relationship was found with the age of the subjects (p >0.05).

Conclusion: The established reference values of the cross-sectional area of the tibial nerve will aid in early diagnosis of peripheral neuropathy.

正常胫骨神经高分辨率超声截面积的参考值。
目的:建立高分辨率超声胫骨神经截面积参考值,探讨胫骨神经截面积与受试者年龄、性别、身高(cm)、体重(kg)、体质指数的关系。方法:对200名年龄在18岁以上、无周围神经病变或下肢创伤史的男女受试者进行高分辨率超声检查。测定两下肢坐骨神经分岔处胫腓总神经下1 cm处(ⅰ节)和内踝前后1 cm处(ⅱ节)胫骨神经平均截面积。结果:ⅰ节测量的平均截面积(0.196 + 0.014 cm2)大于ⅱ节测量的平均截面积(0.111±0.011 cm2)。平均横截面积与身高、体重、体质指数呈正相关(p >0.05)。结论:建立胫神经截面积参考值有助于周围神经病变的早期诊断。
