Deviations observed during operations triggered our effort to initiate an investigation concerning variations in the formation of brachial plexus.
In 50 cadavers of adult subjects the authors examined 100 brachial plexuses in order to detect incidence of neural variations. The participation of the C4 radix or Th2 radix as well as various variants from outlets of individual radices and their branches from the vertebral column to the variants in the formation of nerve trunks was investigated. The attention was devoted to their course, anastomoses, thickness and occasional absence. In addition to anatomical complexity and variability, attention is paid to motor innervation peculiarities in relation to diagnosis. The attention is paid to the mechanisms and morphological reasons in the origin of certain type of injuries.
The prefixed type occurred in 24 cases (48%), the postfixed one in a singe case. In 25 cases (50%) 32 deviations were observed. The deviations were more frequent on the left side in 11 cases.
The study made it possible to find out and describe exceptional, so far unpublished, anatomical deviations in the formation of nerve radices and trunks of brachial plexus.
手术过程中观察到的偏差促使我们着手对臂丛神经形成的变异进行调查。
作者对50具成年尸体的100个臂丛神经进行了检查，以检测神经变异的发生率。研究了C4神经根或Th2神经根的参与情况，以及各个神经根从脊柱发出处及其分支到神经干形成过程中的各种变异。重点关注它们的走行、吻合情况、粗细以及偶尔的缺如。除了解剖结构的复杂性和变异性外，还关注与诊断相关的运动神经支配特点。关注特定类型损伤发生的机制和形态学原因。
前置型出现24例（48%），后置型1例。25例（50%）观察到32处变异。左侧变异更常见，有11例。
该研究使得发现并描述臂丛神经根和神经干形成过程中迄今未发表的特殊解剖变异成为可能。
