摘要
目的探讨正常臂丛神经根的声像图特征及定位标志,以对神经根发出位置水平进行准确定位。方法对40名正常人进行臂丛神经超声检查,以C7椎体横突前结节短小或缺如这一形态学特征为标志,以椎体长轴为轴线,于横断面判定各个神经根发出椎间孔的相应椎体水平,观察C5-T1各神经根的超声声像图的特征。结果通过各颈椎椎体横突的超声表现可辨认和识别神经根发出水平,C7神经根出椎间孔段的超声声像图具有特征性。于40名受检者均可观察到C5-7水平的神经根,25名可见C8神经根,7名可见T1神经根。结论高频超声能利用椎体横突的形态学的差别区分和定位各个神经根所对应的椎体水平,对臂丛神经损伤的定位诊断提供依据。
Objective To explore the ultrasonographic features of the roots of the brachial plexus and location mark in normal adults,and to confirm the exact location given by nerve root.Method Forty healthy adults underwent ultrasonography,and the sonographic features of C5—T1 root level were observed.The levels of brachial plexus roots were identified using the transverse processes as landmarks on cross section,especially the absence or the shortness of the anterior tubercle from C7 level transverse processes.Results The levels of the roots of the brachial plexus with ultrasonography by means of the evaluation of their transverse processes were identified.C7 level of brachial plexus root nerve had distinct characteristics in ultrasonogram of intervertebral foramen.The overall nerve roots of C5—7 were revealed in all 40 subjects,of C8 in 25,while of T1 only in 7 subjects.Conclusion High frequency ultrasound can reveal the levels of the roots of the brachial plexus on the basis of the different morphology in terms of the transverse processes of the vertebrae,therefore providing basis for the diagnosis of brachial plexus injuries.
