title: [Anatomic deviations in the origin of the median nerve].
abstract: OBJECTIVE
  Deviations detected during the operation triggered our interest to start work dealing with variations in the formation of n. medianus
  One hundred brachial plexuses were examined in order to detect variations of n. medianus. Attention was paid to the course and anastomoses.
  
  
  RESULTS
  In 32 cases (64%) the authors observed 40 deviations. The deviations occurred more frequently on the left in 16 cases. They were most frequently of anastomosis character.
  
  
  CONCLUSIONS
  The study made it possible to detect and describe deviations in the formation of n. medianus up to the lower third of shoulder.
